New DFF grants
We are very grateful to have received funding from DFF for our ongoing efforts with NALCN, as well as ASIC. The latter grant is a collaboration with the labs of Henriette Autzen and Joe Rogers and we hugely look forward to getting this off the ground together with them. Watch this space for updates on the projects.
Lab members on the road
Our TEVC rigs are less busy than usual these days because Hendrik and Sam are busy patching neurons abroad. Specifically they are visiting the labs of Arnaud Monteil in Montpellier and Christian Rosenmund in Berlin, respectively. Happy recordings and we look forward to welcoming you back later in the year!
Stephan was hosted by Lundbeck Foundation Collaborative Grant collaborator Prof Mei Zhen at the Lunenfeld-Tanenbaum Research Institute, before visiting Adriano Senatore at the University of Toronto Mississauga, as well as a short stint at ProteinQure. Big thanks to the hosts and to everyone involved for inspiring discussions and input.
New preprint on NALCN pharmacology
NALCN is notorious for its resilience towards pharmacological manipulation. In our latest preprint, we find that unplugging DI-DIV and DII-DIII lateral fenestrations reveals an unexpected pharmacology. All credit goes to former MSc student Katharina Schott and to former postdoc Han Chow Chua, now lecturer at the University of Sydney, for leading this project. The full story can be found HERE.
Tim in town
4 years after his move to Bergen, Norway to set up his own lab, we had the pleasure of hosting Pless lab alumus Timothy Lynagh. It was great to have him in town and to hear about all the cool ion channel work they have going on up there near the Polar Circle! Thanks for swinging by, Tim, and very nice to see your lab doing so well!
NALCN workshop in Alicante, Spain
Registrations are now open for the first-ever workshop on NALCN with the goal to bring together PATIENT FAMILIES, PHYSICIANS and RESEARCHERS to improve the lives of patients. The event is hosted by the Libellas Foundation.
Genetic code expansion talk
Stephan was fortunate enough to be invited to contribute to the virtual genetic code expansion (GCE) seminar series. This was a welcome opportunity to share some of our recent efforts on introduction of non-canonical amino acids into ASICs. A recording of the talk can be found HERE.
Stephanie returns from maternity leave to re-join our efforts on ASIC, while Emma starts her PhD work on NALCN. Welcome back and we hugely look forward to having you around (again)!
Two Marie Curie Fellowships
Delighted to share the news that we will have two incoming Marie Curie Postdoc fellows this year! Nadine Ritter will re-join the lab to work on NALCN and Laurie Peverini will start working on splicing in Nav1.5 – big congratulations to both and we look forward to having you around from later in the year!
Victor is a MSc student that will team up with Sam (and Alex Hauser) to work on computational approaches on the NALCN complex and Mikkel is a project student who will join Mette in her quest to unravel the functional consequences of protein-protein interactions in ligand-gated ion channels.
Hello and farewell
Time to say a big thank you to Fadumo, who has been a terrific lab tech intern over the past year. Your help was greatly appreciated and we wish you all the best for the future. At the same time, we welcome Hanna to the team, who will be our lab tech intern for the next 12 months – we look forward to having you around!
New manuscript on bioRxiv
Our latest endeavours into protein engineering show that ASICs are exquisitely sensitive to side chain length and charge at a conserved Lys in the extracellular domain – one carbon can make all the difference! Big thanks to postdocs former postdocs Debayan Sarkar and Iacopo Galleano for leading this effort, assisted by former MSc students Sofie Ou and Gül Uzun, as well as the contributions by lab alumnus Keith Khoo and Gerbrand J.v.d.H. van Noort from Leiden (Netherlands)! We are very grateful for funding by the Lundbeck Foundation and the DFF. The current version of the manuscript can be found HERE.
New grant from the Lundbeck Foundation
We are very grateful for a Lundbeck Foundation Collaborative Project grant. This will enable us to study and target the sodium leak channelosome together with the group of Prof Mei Zhen in Toronto over the next five years.
Thanks for 2022
2022 was an exciting year, with lots of progress in the lab, new faces, sad goodbyes, finally some conferences again and plenty of ideas to keep us occupied for the year(s) to come. Big thanks to all the many contributors and their ceaseless efforts to keep the lab running (and make it more green!), as well as their curiosity and perseverance to push our projects forward!
Congratulations to Claudia
Congratulations to Claudia for successfully defending her PhD thesis! Her work focused on studying the effects of disease-causing mutations in the NALCN channelosome and contributed to classifying them according to the type of mutation. We wish her all the best for her future and also thank her thesis assessment committee, Hanne Poulsen, Arnaud Monteil and Petrine Wellendorph
Talking about split inteins in California
After a long Covid-related delay, the ‘Chemistry and Biology of Peptides’ GRC finally went ahead in Ventura, California. Big kudos to the organizers for putting together an exciting and diverse program covered a staggering array of peptide science – a big honor for the lab to be able to showcase some of our intein magic!
Lab represented at SHIFT 2022
Stephan had the honor of presenting some of our ASIC work at the second “Doing biology with light” meeting on Tenerife. Big thanks to Drs Teresa Giraldez and Andrew Plested for putting together a very inspiring meeting in a spectacular place. Fingers crossed the third iteration of “Doing biology with light” is not too far off!
Nadine and Hendrik present at Europhysiology
The Europhysiology 2022 meeting brought an abundance of physiology experts to town, including some interested in ion channels. This presented a great opportunity to showcase some of our recent efforts to incorporate non-canonical amino acids and post-translational modifications into Nav1.5 and NALCN, presented by Hendrik and Nadine, respectively. It also provided a welcome opportunity to catch up with collaborators and friends!
Visit by NALCN expert
This week, we have the pleasure of hosting Dr Arnaud Monteil from the CNRS Montpellier. Arnaud is an expert on many aspects of NALCN physiology and we look forward to having him around for a few days!
Lab retreat 2022
Unlike previous years, we left town only for a single day for our annual lab retreat – this time to the island of Hven. Awkwardly making our way across the island on tandem bikes, we learned about its illustrious history, incl its past as the former basis for Tycho Brahe’s astronomy studies and its current efforts to distill liquor with the help of music – go figure! Thanks to the team for a fun day out!
Bidding farewell to Chow
After a record-breaking 6 years in the Pless lab, Chow moved on to new adventures – for which we wish him all the very best! He deserves huge credit for helping to lift NALCN (and its auxiliary proteins) from relatively obscurity back into the ion channel limelight – and giving us plenty of work on (and things to think about) for the years to come. Thank you for your many contributions, you will be missed!
Sam talks at channel GRC
After various pandemic-related delays, it was finally time for the ion channel GRC in Mt Holyoke again. Sam and Stephan got treated to a fantastic line-up of speakers and Sam did a great job presenting his latest effort into identifying new interaction partners of the NALCN complex. Huge thanks to the organisers for a fun week full of channel magic!
Congratulations to Gül and Sofie
Big congratulations to Gül and Sofie for passing their MSc thesis defense yesterday. They both did a fantastic job over the past 9 months learning about and working on split intein-mediated protein splicing on acid-sensing ion channels. They made a huge contribution to the project and we wish them all the best for the future!
Two more farewells
We had a nice farewell breakfast for Debayan and Stephanie. Luckily, it is only a temporary ‘Auf Wiedersehen’ for Stephanie, as we can look forward to her returning after parental leave to continue her ASIC adventures! Debayan will move onto new endeavours elsewhere, for which we wish him all the best! We are very grateful for him deploying the split intein magic on an entire zoo of different channels for the past two years – and for always being a cheerful lab mate and dedicated supervisor!
LEAF Bronze status for Pless lab
Thanks to the efforts by Janne, Fadumo and Hendrik, the lab has now achieved the Bronze level certification status of the LEAF program. The programs aims at making laboratories (and the work in them) more sustainable and we hope to tackle Silver status next!
Goodbye to Iacopo and Nadine
After 5 months as an exchange PhD student, it was time to say goodbye to Nadine – and thank her for astounding amount of NALCN patching she got done in this short time period! We wish her all the best for the remainder of her PhD and very much hope to see her again in the future!
Iacopo had been in the role of the resident (and later remote) Pless lab peptide magician since 2018 and will be missed on all levels! Thank you so much for all your amazing contributions to the many projects you were involved in and, most importantly, for enabling the intein magic around here in the first place! We miss you (and your pink shirts) already and wish you all the best for your new adventures!
EMBO/FEBS lecture course in Erice
After being postponed twice, the EMBO/FEBS lecture course on ion channels and transporters finally went ahead in the sleepy Sicilian hill town of Erice! Not everything was as expected (think thick fog, rain and wind instead of sunshine) or hoped for (participants with Visa issues and numerous Corona infections), but the food and science part delivered: delicious local bites and a fantastic lineup of didactic and science lectures, poster sessions and many informal discussions! Big thanks to all contributors, students, speakers and, especially, our sponsors and the local organisers!
Stephan talks in Linköping
One of the many 2022 events that got postponed numerous times, the Wallenberg symposium finally took place in Linköping, Sweden – Stephan was very honored to join the great speaker lineup (and visit friends and colleagues).
After various COVID-related delays, Stephan finally got to celebrate his inauguration as Professor at the Dept of Drug Design and Pharmacology. Huge thanks to all lab members (past and present), colleagues and collaborators – it would have never (ever) happened without you!
Ligand recognition GRC in Lucca, Italy
Stephanie and Stephan got to attend the GRC on ligand recognition and molecular gating in Lucca, Italy. The densely-packed program did not leave much time to admire the achingly beautiful surroundings, but the science was top-notch. Big kudos to the organisers!
Structure of Nax-Nav beta3 complex
Our latest collaboration with the Payandeh and Ciferri groups at Genentech reveals the structure of human Nax/Nav2.1 in complex with Nav beta3; now out in Nat Comms. Despite looking very similar to Nav/Cav channels, its functional properties appear to diverge substantially: numerous lipids populate the pore, physiological activation mechanism remains elusive, but channel engineering suggests it is non-selective among monovalent cations, inhibited by TTX, Ca2+ and some Nav inhibitors. Cameron Noland and Marc Kschonsak spearheaded the structural efforts, while Chow masterminded the functional interrogations on our end, together with Stephanie and Nina. Big thanks to everyone one involved. Now all we need is somebody to find out how this channel is activated endogenously…
P2X2 manuscript published
After years of delays, our work on the intersubunit interfaces of P2X2 receptors finally got published! We show that subunit interfaces are missense mutation hotspots & mutations here tend to increase apparent ATP affinity. Huge thanks to everyone involved, in particular Federica Gasparri for her patience, Alexander Hauser for his contribution to the population analysis and Debayan Sarkar for getting it over the line!
Biophysics meeting 2022
Biophysics 2020 was the last in-person meeting pre-Covid, so it was only fitting that Biophysics 2022 would kick off real-life conferences again. Although only Debayan and Stephan made it to California in the end, the lab was strongly represented with 2 talks and 3 posters. Definitely exciting to catch up with friends and collaborators in person again – and big thanks to the organisers for an outstanding and diverse program, as well as for providing a safe environment.
ASIC-PcTx1 paper out now
After many years of work, our epic effort into figuring out the mechanism and stoichiometry of how the peptide toxin PcTx1 inhibits ASICs is finally published in eLife. This really was a long-term effort and a great collaboration between Stephanie and Christian – thank you for your persistance and for generating very thorough mechanistic insight into this tricky problem!
Hi and goodbye
Yesterday, it was time to say farewell to our 2021-2022 lab technician intern Marijana. Big thanks for all her help and we wish her all the best for the future! Today, we say hi to Fadumo, who will be our 2022-2023 lab technician intern – welcome to the team!
Today, Nadine Ritter joins us as a visiting PhD student from the University of Muenster, Germany. She will be working on NALCN with Sam for the next 4 months. Welcome and we look forward to having you around.
Say hi to 2022
While we say hello to the new year, I would like to take the opportunity to thank the amazing Pless lab team for hanging in there during the past 12 months. Certainly not everything went to plan and Corona did its best to make things tricky, but I am very grateful for everyone’s efforts and enthusiasm to push things forward! Here is to the new year, along with all the highs and lows it may bring. Looking forward to seeing all the exciting projects progress!
Structure of NALCN channelosome published
After years of work and a big team effort, our structure-function effort on the entire NALCN channelosome is now published in Nature. Together with our fantastic collaborators (Payandeh and Ciferri labs @ Genentech, Manu Ben-Johny @ Columbia, and Alexander Leitner @ ETH), we show that UNC79/80 form a massive figure-8-like HEAT repeat assembly below the channel, CaM co-purifies as a surprise passenger and single channel data reveal very low Po. Check out all the details HERE. Congratulations to the entire team, especially Marc Kschonsak and Han Chow Chua, who took the lead on deciphering structure and function of this massive complex. We are very grateful for support by the Carlsberg Foundation, DFF and the Lundbeck Foundation. Lastly, congratulations also to Kang & Chen, who preprinted very similar work HERE.
Infrastructure grant from Carlsberg Foundation
We are very grateful for an infrastructure grant from the Carlsberg Foundation that will support our efforts to decipher the function and structure of the NALCN channelosome.
Stephan talks in Stockholm
After what felt like an eternity, Stephan got to talk in person again abroad – big thanks to Lucie Delemotte and Reba Howard for hosting a fun visit at the SciLife Labs in Stockholm!
Today, we welcome Paolo Zucculini from Italy, who will do a short stay in our lab to get some experience in VCF recordings.
Our first-ever review on ASICs
Congrats to Stephanie for this epic effort to assemble an overview of what animal models have taught us about the potential of acid-sensing ion channels as therapeutic targets. Apart from the well-studied stroke implications and the tricky area of pain, ASICs may turn out to be suitable targets in a number of other diseases – check out the details here.
New paper out in PLoS Biology
After many years of big efforts, Nina’s paper on incorporation of photo-crosslinking ncAAs is finally out in PLoS Biology. The project took many twists and turns, but thanks to the courage and tenacity of Nina, it all worked out in the end. Special kudos to Jacob Andersen for kicking off the idea and big thanks to our fantastic collaborators from the Andrea Sinz group and Nanion!
Welcome to Caroline, Gül, Sam and Sofie
Today, we welcome four new people to the group: Caroline is joining as a scholar student to work on ASICs with Stephanie; Gül and Sofie will be working on ASICs with Debayan as part of their MSc thesis and Sam joins from Oxford as a postdoc to work on NALCN. Welcome and we look forward to having you around!
CBP annual retreat
This year’s CBP retreat was all about creativity (day 1) and equality, diversity and inclusion (day 2). Set at the beautiful F’berg campus, we were lucky to be entertained by excellent speakers: Itai Yanai (NYU) and Martin Lercher (Düsseldorf) from the Night Science podcast & Roshni Mooneeram (EMBL) and Vanessa Hall (UCPH). Big thanks to everyone involved for making this happen!
Latest paper on ASIC selectivity
Big congratulations to Zeshan for his heroic effort on deciphering how M1 and pre-M1 contribute to ion selectivity in ASICs and ENaCs. Him, Matthias and Tim were fortunate enough to be assisted by strong collaborators from both academia (Mike Althaus, Bonn) and industry (Nanion Technologies, Germany), but it was Zeshan who really spear-headed this project. It ended up involving chimeras, non-canonical amino acids, automated and single channel patch-clamp and much more and really helped us understand key differences between ASICs and their constitutively active cousins from the ENaCs family. The paper just came out in JGP.
New paper out in PNAS
Thanks to a collaborative effort involving split intein-mediated protein engineering and MD simulations (credit to the group of Prof Lucie Delemotte), we were able to show how some Nav1.5 patient mutations are functionally benign – until they get phosphorylated and wreak havoc on inactivation. We were also able to provide insight on the basic mechanism of inactivation and how phosphorylation can affect Nav1.5 pharmacology. Big kudos to Keith Khoo for providing the foundation for the project. Get the full story here.
Our latest ASIC study on bioRxiv
The work represents the culmination of a long-term effort to decipher the stoichiometry and conformational landscape of the ASIC-PcTx1 interaction. Started way back in 2015, it took many concatemers (big thanks to Janne!) and countless recordings of WT and virtually toxin-insensitive channels (with and without fluorescent labeling) to decipher the mechanism and stoichiometry of this interaction. Read the full here.
On the road back to normality
As government and university restrictions are lifted, we can finally look forward to more lab events again! After a long Covid-related hiatus, we will re-start our boating tradition, have an in-person MSc day and also go on a lab retreat – lots of things to look forward to!
Chow talks in Oxford
Congrats to Chow for being given the opportunity to talk (virtually) at the Oxford Department of Pharmacology about his work on NALCN – and thanks to Paolo Tammaro for hosting!
Ion Channel Symposium
Congratulations to Stephanie and Chow for putting together a hugely popular virtual ion channel symposium. They assembled a great line up of speakers and as a result, both days of the symposium attracted around 250 attendees. The talks can now also be viewed on YouTube: Talks from Day 1 and Talks from Day 2.
Congratulations to Janne
Janne had her 25-year work anniversary at the institute today – congratulations! Along with the rest of the department, we are extremely grateful for all her contributions, help and advice in pretty much every imaginable matter. Thank you for being around and thank you for being awesome!
Finally on the web!
After many delays (mea culpa!), we finally posted our work on P2X2 receptor gating on bioRxiv. Huge thanks to Federica Gasparri, first-ever PhD student of the Pless lab, who was later joined by Sarune Bielickaite and Mette H. Poulsen on the project. We show that mutating the inter-subunit interfaces consistently increases apparent ATP affinity.
Welcome back, Hendrik
After doing his thesis work with us and finishing his MSc (equivalent) in Germany, we are delighted to welcome Hendrik Harms back as a PhD student. He will be working on atypical sodium channels and we very much look forward to having him around again!
Intein-mediated engineering of channels
Congrats to Debayan and Hendrik for leading the efforts on this book chapter on split-intein mediated engineering of ion channels. Big thanks also to Iacopo and Zeshan for helping to putt together this chapter, which will hopefully help others to implement this powerful approach. The chapter is online now HERE.
Register for ion channel symposium
Registration is now open for the first ion channel symposium on ‘Novel members, structures and function’ – sign up for free here. The May 5th and 6th event will be fully online and feature an exciting line up of ion channel experts from around the globe.
New preprint on bioRxiv
Congrats to Zeshan for leading this big effort into the contributions of M1 and pre-M1 to ion selectivity in ASICs and ENaCs. The work features plenty of ephys (whole cell, single channel and high throughput), plus >80 conventional mutants, plus non-canonical amino acids and more – and can now be found on bioRxiv. This study would not have been possible without the other contributors and collaborators Matthias Wulf, Timothy Lynagh (now in Bergen, Norway), Mike Althaus (Bonn, Germany) and Søren Friis (Nanion Technologies)
Welcome back, Mette and Katharina
We are delighted to welcome Mette and Katharina back to our team! Mette re-joins after maternity leave to continue her exciting work on protein-protein interactions and Katharina will conduct her MSc thesis work on NALCN – great to have you around (again)!
Welcome on board, Marijana
Today, we say hi to Marijana Oljica, who will be around as a laboratory technician intern for the next year – welcome and we look forward to having you around!
Alex was our latest lab tech intern and we are very grateful for all your help over the last (and slightly chaotic) year. Thanks and all the best for your next move(s).
We continue our (sad) string of farewells in early 2021 by saying goodbye to Zeshan. He had joined in 2016 as a PhD student and has since greatly helped us understand ion selectivity in ASICs and ENaCs. He has been immensely productive and he will be missed a lot! Thank you for everything and all the best for your next endeavours – we hope to still see you around occasionally!
Nina says goodbye
Today, it was time to bid our (socially distanced) farewell to Nina. We are very sad to see her move on after having been around for the past 6 years – and having been instrumental in setting up much of the ncAA and ASIC efforts around the lab. Thank you so much for all your contributions in and around the lab – you will be missed a lot! Wishing you all the best for your next endeavour!
Congrats to Iacopo and Hendrik
Our latest endeavour into protein semi-synthesis / MD combo is out on bioRxiv. Together with our fantastic collaborators from the Lucie Delemotte lab, we show how Nav1.5 patient mutations can be functionally benign – until they get phosphorylated and then wreak havoc on inactivation. Great job by Iacopo and Hendrik putting this together and we are grateful for support by DFF and the Lundbeck Foundation.
Well done Stephanie!
Congrats to postdoc Stephanie for being awarded an infrastructure grant from the Carlsberg Foundation. The grant will support her efforts into understanding how neuropeptides modulate ASICs – read further details HERE.
Farewell to Christian
After a productive 5 years in the Pless, we are very sad to see Christian move on. He has been instrumental in many of our ASIC-related projects, especially those involving neuropeptides and toxins – and will be missed tremendously by us all! Thanks for being a great lab members and all the best for whatever awaits you on the other side of your 4 month-daycare career!
Ninas new preprint is out
Congrats to Nina for getting her primary PhD project out on bioRxiv! She established a way to record from ncAA-containing ASICs on an automated patch-clamp (APC) device – and used the approach to dig into the details of the function and pharmacology of up to 309 ASIC variants. Huge thanks to our collaborators: Jacob Andersen for getting this off the ground, Søren Friis from Nanion for lending us his APC expertise and the Team of Andrea Sinz in Halle for their help with mass spectrometry!
More good news
We are immensely grateful for the Novo Nordisk Foundation to support our latest endeavours into the world of atypical sodium channels. We very much look forward to getting this new project off the ground in 2021 – stay tuned!
Chow talks in Canada (virtually)
Chow was invited to present some of our recent data on the function and structure of NALCN at the University of Alberta, Edmonton.
How to neutralize a snake toxin
After years of work, this collaboration on peptide inhibitors of the alpha-cobratoxin-nAChR alpha7 interaction is finally out. Big thanks to everyone involved, especially to Brian Lohse for initiating it all, our lab neighbours Christian Olsen and Bengt Gless for affinity measurements, the Daniel Kümmel group for structural work – and the tireless Tim Lynagh for pretty much everything else! Read the full story in J Med Chem now.

Congrats to Asli
Congrats to Asli Topaktas for successfully defending her MSc thesis today. She was the fourth and last MSc student to finish this year and she has helped us decipher some of the details of how ASICs are modulated by toxins and neuropeptides – thanks and all the best for the future!
Well done Aisha Ameen, who successfully defended her MSc thesis today! Aisha helped us decipher the function of a whole range of NALCN patient mutations. We will miss having a native English (British!) speaker around and we’re wishing her all the best for her next endeavours!
Johann defends his MSc thesis
Congrats to MSc student Johann Sigurdsson for successfully defending his thesis yesterday. Big thanks for helping us understand some of the effects of protein-protein interactions on ASICs – and all the best for your future!
Well done, Dr Sheikh
Congrats to Zeshan for successfully defending his PhD thesis today. Over the past 3 years, he made huge contributions to our attempts to decipher ion selectivity in ASICs and ENaCs. He then demonstrated strong nerves when having to write up and defend during a pandemic – well done!
Big thanks also to the assessment committee, consisting of Drs Palmer, Premdjee and Kristensen.
Congrats to Peilin
Congrats to our MSc student Peilin Tu for successfully defending her thesis today. She helped us understand how Nalcn is modulated by auxiliary proteins. Well done and best of luck with your future endeavours!
2020 lab retreat
This year, our annual lab retreat took us to Sjællands Odde, where we were hosted in Janne’s beautiful summer house. Big thanks to everyone for contributing to our lively discussions on stress(relief), reproducibility, research integrity and minimizing waste around lab. Fingers crossed we can do our next retreat without face masks.
Welcome to new postdoc Debayan
Debayan Sarkar finally made it to Denmark today after a (multiple month) long delay due to the COVID-19 situation. He joins us from India, where he conducted a very successful PhD working on (mostly) peptide modulation of TRPV1 channels – welcome and we look forward to having you around!
Today, we welcomed Katharina Schott to our team. She joins us from the University of Vienna for a internship this fall, followed by her MSc thesis work in 2021 – we look forward to having her around!
Review in J Physiol
Structure of NALCN out in Nature
Great collaboration with the Ciferri and Payandeh groups out in Nature now: Structure of the human sodium leak channel NALCN/FAM155A complex.
The work explains how a) FAM155A forms a dome-like structure above the pore to determine the notorious NALCN pharmacology, b) structurally unique voltage-sensing domains mediate the odd voltage-sensitivity and c) disease-causing mutations cluster around the pore module to affect channel function.
Congratulations to the teams on both sides! Especially excited for Marc, Chow, Cameron and Claudia, who lead our efforts on structure and function! Big thanks to the amazing (and tireless) Jian, as well as our local undergrad students Aisha and Oskar for their contributions.
My group is hugely grateful to the Carlsberg Foundation, DFF and Lundbeck Foundation for their continued support since the early stages of this exciting project.
Big thanks to external lab meeting speakers
We are very grateful to Anna Ulstein Odland (UCPH, DK), Eva Kaulich (MRC, UK) and Valeria Kalienkova (Univ Groningen, NL) for agreeing speak at our recent virtual lab meetings! Great to hear about their exciting science – and a fantastic opportunity for us to learn more animal models, funky channels and cryo-EM!
Lab is back in action
After over two months of zero, or at least very restricted lab access, we are delighted to report that we are back in action. Distancing and hygiene rules stay in place, but everyone as able to come to the lab again and continue their projects.
Things have been challenging in many ways since the shutdown, but the team did a fantastic effort to make the best of the situation – kudos to everyone’s patience and resilience!
Protein engineering paper out in Nature Communications
Huge congrats to the whole team, lead by the terrific and fearless duo of Keith and Iacopo, for putting together a terrific study on protein engineering! Initially not more than a somewhat abstruse idea, the team managed to insert synthetic peptides into a variety of proteins in life cells using what has become internally known as ‘intein magic’. The work is now published at Nature Communications, including a blog post in the Nature Research Bioengineering Community.
Thanks also to our collaborators from the Tampé group in Frankfurt – and to our funders for enabling us to bring this idea to life.
Our first NALCN paper out in Science Advances
After a big effort from Team NALCN, our first paper on the NALCN complex is now out in Science Advances. We show that NALCN-mediated currents are only observed in the presence of three auxiliary proteins – and that the leak activity is modulated by both extracellular calcium and voltage. Big thanks to Chow, Matthias, Claudia and Lise for all their hard work on this tricky project!
First step back towards normality
After exactly 6 weeks of shut down, we are excited to report the partial re-opening of the lab! For now, it will only be one person at a time, but it is great to know that we are able to get our projects going again. Big thanks to all lab members for their patience – both over the last few weeks and now during this slow re-opening phase.
New ASIC paper out in PNAS
We are delighted to announce the formal publication of our latest paper on ASICs in PNAS. The work, lead by postdocs Christian, Nina and Stephanie, shows how a neuropeptide binds to and modulates ASIC1a. The study involved many different technologies and we are hugely grateful for the contributions by our terrific collaborators in the Bennett and Strømgaard labs at KU! Due to its potential implications in pain, the work was featured in a KU press release and on Eurakalert!
Lab shut down due to COVID-19 crisis
Like most other labs around the globe, we are currently shut down. Nobody is allowed in the lab and all scientific activities are limited to online meetings, reading, writing and project planning tasks. This creates a whole new set of challenges for everyone involved, but the team has been fantastic in keeping up the spirit during this unusual time – huge thanks to everyone for their continued efforts and motivation to restart their projects as soon as we are allowed back to the lab!
After half a year in the lab, it’s time for Oskar to move on. He was fortunate enough to be financed by a NNF pre-graduate scholarship and has done a fantastic job working on NALCN – he will be missed!
Pless lab in San Diego
Nina, Chow and Stephan represented the lab at the annual meeting of the Biophysical Society in San Diego. This was a great opportunity to catch up on the latest science and meet old (and new) friends. Nina presented a very well-received ASIC poster, Chow gave a great talk on NALCN and Stephan took home the Paul F Cranefield award by the Society of General Physiologists (SGP), making for a very successful meeting overall!
New paper on bioRxiv
Proud to present our first foray into protein semi-synthesis. Using Nav1.5, P2X2R and GFP as examples, we show that tandem protein trans-splicing can used to insert synthetic peptides into proteins in live cells. The project was lead by two fantastic postdocs, Keith Khoo and Iacopo Galleano, with assistance from a number of other lab members, as well as our collaborators from the Tampé group in Frankfurt. Full paper can be found on bioRxiv.
After providing fantastic help and assistance with many projects in the lab, lab technician intern Cristina is moving on to finish her education. Thank you very much for everything, you did extremely well and we wish you all the best for your future studies!

Our work on NALCN is on bioRxiv
Huge thanks to postdoc Chow and the rest of the NALCN team for their epic efforts to put this manuscript together. We demonstrate how the elusive sodium leak channel requires the presence of three other neuronal proteins to be robustly expressed in heterologous systems. We then go on to show that its constitutive activity is modulated by both voltage and extracellular divalent cations, in particular calcium. All the details to be found on here. We are very grateful for the support from the Danish Research Council, the Carlsberg Foundation and the Lundbeck Foundation.
Congrats to Yasmin
After over a year in the lab, it was Yasmin´s turn to defend her MSc thesis.

Farewell and thanks to Matthias
Today, we said goodbye to former PhD student and postdoc Matthias. Being only the second-ever PhD student in the Pless lab, he was there from pretty much the beginning and has made a huge contribution to setting up methods and making the lab the place it is today. Not only has he (single-handedly) established high-sensitivity patch-clamp fluorometry, but he has also worked with single channel recordings, FRET, unroofing of mammalian cells etc – and always been a role model in persistence and patience. He will be missed dearly and we wish him all the best for his next move!
Iacopo and Stephan in Kyoto
Iacopo and Stephan were fortunate to enough to be able to attend the 10th International Peptide Symposium in Kyoto, Japan.

Welcome Sarune and Jamie
We are very happy to announce that Sarune and Jamie will be joining our team for a 1-year MSc thesis – welcome and we look forward to having you around!
2 new publications in JGP
We are very grateful to have been part of a fun collaboration with the Kurata lab at the University of Alberta, Edmonton, Calgary on the mechanism of two related potassium channel openers. In two back-to-back manuscripts in JGP we describe how these compounds (one of them in use as an anti-epileptic) require very different drug-channel stoichiometries to affect channel function: despite their resemblance, one of the requires only a single drug binding site per channel tetramer, while the other requires drug binding sites on each of the four channel subunits to have its full effect. Here are the links to the retigabine story and the ICA study.
Big funding success for Tim
Congratulations to Tim for securing a coveted ERC starting grant! We wish him all the best for starting his own group later in the year and have no doubt he will put the grant to good use over the next 5 years. Find the link to the KU SUND news feature here
Trip to the sunny south
We were lucky enough to be able to spend the 2018 edition of our annual lab retreat at Lake Como, Italy. Although our lodgings were not quite as fancy as George Clooney´s famous lakeside estate only meters further down the road, we greatly enjoyed our two days of science presentations and hikes. Thanks to the advice and planning by local and former PhD student Federica, we were treated to great food and superb views – while also brushing up on a lot of the technologies used in the lab (e.g. obsessing over Western blots, series resistance compensation and color palettes). Thanks everyone for making it a productive and fun outing!
Well done, Zeshan
Following in the footsteps of his PhD student predecessors, Zeshan delivered an award-winning presentation at the annual DRA Research Day – congrats on the poster prize!
New paper online
Together with the Strømgaard and Jemth groups, we have just published a review on probing backbone hydrogen bonds with amide-to-ester substitutions.

Today, we welcome Claudia Weidling as our latest PhD student. Originally from Hamburg, she has ample experience in protein biology and will join Chow and Lise on a new project in the lab. Welcome and we look forward to having you around!
Congrats to Tim
Together with our collaborators from the Glover group in Norway, Tim has worked hard to shed new light on the emergence of proton sensing – which, as it turns out, has happened a lot longer ago than previously anticipated. He also spent significant efforts on elucidating the mechanism of proton sensing itself, a topic that continues to puzzle the field. The work has been accepted at PNAS, where it can currently be found in the “Latest Articles” section – follow the link HERE.
A huge thanks to Tim!
After 4 1/2 very successful years in the Pless lab, Tim moves on to establish his own group later in the year. Tim was the first group member of the Pless lab and has been instrumental in setting up the lab and getting various projects off the ground – and looking at his track record, he has done so in a very successful fashion: he has published high-impact papers (his latest one can be found HERE), acquired highly competitive postdoc-fellowships and also established himself as a recognised expert amongst ion channelologists, as evidenced by his latest assignment as chair of the Ion Channel GRS in the US!
We wish Tim all the best for the adventures ahead and hope to still get to see him every once in a while – he will be missed!
Gordon Conference on Ion Channels 2018
Every two years, ion channel geeks from around the globe gather in the middle of nowhere (South Hadley, to be precise) to attend the Gordon Conference on Ion Channels. The Pless lab made a good showing this year, with 4 posters, a talk by Keith and Tim chairing the research seminar preceding the main meeting.

Congrats to Nina. Again.
Competing with other PhD students from all over Europe, Nina was able to secure a coveted Boehringer Ingelheim Fond PhD fellowship – congrats and well done, Nina!
You would think that 2 years after moving in we would be past any issues related to noise. Well, think again. Thanks to a (not so) brilliantly timed and communicated renovation effort half the department will need to come to work with heavy-duty ear mufflers until the end of the year – or just stay at home. Then again, at least we´ll be well prepared to deal with the inevitable Christmas jingle onslaught.
Congrats to Nina
We´re very happy to report that Nina just received a PhD scholarship from the Lundbeck Foundation!
Welcome Camilla, Daniel and Sarah
After some of them had already joined us on our lab retreat, we´re very happy to have three new MSc students join the team: Camilla Lund, Daniel Vasquez and Sarah Yandurah – looking forward to having you guys around!

Biophysical Society meeting 2016
Courtesy to travel awards to Federica (Biochemical Society), Matthias (Lundbeck) and Tim (DFF), we were able to treck across the pond with quite a few lab members this year. Greeted by sunny and warm weather, it quickly became clear that – thanks to a busy program – we would not have time to indulge in either. Instead, we were treated to an excellent meeting, with very successful poster presentations by Nina, Federica and Matthias.
Welcome Nina and Alba
After a very productive MSc thesis last year, Nina returns as a PhD student this week. Alba joins us from Spain for an internship over the summer. Welcome both, we´re very much looking forward to having you around!

It really was fantastic to have you around, Vitaly, and we will certainly miss you!
Experts in town
After months of planning, the big day had finally come: Oct 6th, the day of the “Hot topics in protein medicinal chemistry” symposium. The line-up was absolutely world class and I think it´s safe to say nobody in the audience went home disappointed – the lectures were absolutely outstanding and extremely inspirational! More coverage of the event can be found here!
More travel for Stephan
Stephan had the pleasure to be invited to the annual meeting of both the French and the Spanish ion channel communities – two fantastic showcases of the exciting ion channel work being done in the warm south! Thanks very much to the organisers for arranging great meetings! (Photo credit: PRBB, likely the research institute with the best location ever – in the center of Barcelona, only meters from the beach…)
It took a while
We´re happy to report the publication of the (likely first) book on how to apply chemical biology approaches to ion channel research – published by Springer, the work can be find under this link. We were very fortunate to be able to recruit world-leading experts to contribute to the book and hope it will find widespread application in the field!
Thanks for the feature
Our latest work on potassium channels modulators just got featured in a science blog – find the details here
Together with our colleagues in Canada, the US and Germany, we have published our latest work in Nature Communications. The work directly shows how a recently marketed anti-epileptic drug elicits its action on a neuronal ion channel. Using synthetic amino acids, we were able to show that the drug, retigabine, binds to the channel primarily via a single hydrogen bond. Curiosly, the H-bond donor within the channel turned out to be the indole nitrogen of a tryptophan side chain, constituting a previously undescribed mechanism of a drug-receptor interaction. Ongoing research in our group, in collaboration with partners from both industry and academia (in Denmark, Canada and Germany), now focuses on complementing this work with detailed SAR studies of retigabine – see also current MSc projects.
We were fortunate enough to receive grant support for purchasing new equipment from the Beckett Foundation, Brodrene Hartmann Foundation and the Hørslev Foundation – we are very grateful for their support!
Goodbye to Nina and Michael
In the past week, we said goodbye to both Nina and Michael, who did an outstanding job in the lab over the last couple of months! While Nina decided to head home the hard way (1200 km by bike), Michael had no choice but to hop on a plane back to the West Coast…
Congrats to Federica
Federica won the poster competition amongst the 2nd year PhD students at the DRA Summer School 2015 – congrats on a job well done! See the link for details
Together with our friends in Edmonton and Iowa, we have just had a paper accepted at Nature Communications – congrats to all involved. Details to follow follow soon!
Talk at UCL
Thanks to Lucia Sivilotti, the leading glycine receptor single channel aficionado (see her recent award lecture on the topic here), Stephan had the pleasure of being invited to UCL for a talk. This meant getting a chance to catch up with some of the world-leading ion channel experts in what has to be the at one of the strongest ion channel/neuroscience departments around – thanks for a great visit.
As our inaugural lab retreat, we left Copenhagen to not only discuss the latest science going on in the lab, but also to check out some massive underground features in nearby Hamburg. More precisely, the tunnels of DESY – built to enlighten us science nerds on all sorts of fancy topics, ranging from our X-ray crystallography of biomolecules (which we are known to occasionally deal with) to quarks, gluons, dark matter and quite literally the big bang itself…
Open PhD position
We currently have a PhD position available for a highly motivated student – check out the details here.
A special guest
We had the great pleasure of welcoming Prof Joe Lynch to town this week. One of the leading glycine receptor experts around, he also was responsible for much of the scientific training of Tim and Stephan, who both did their PhDs with him. More info on Joe can be found here.
Sailing, Viking style
Despite the daunting weather forecast, the members of the Center for Biopharmaceuticals took to the sea at Roskilde in a boat replica of what would have been used by the Vikings a long while back – a fun ride that definitely instilled a lot of respect for those who used tiny boats like these to brave the open waters of the North Sea!
Jose will be working on his MSc thesis with us as part of his MSc degree in Human Biology (here at KU), while Michael is an undergraduate student from the University of British Columbia who is visiting us for the summer – welcome on board, gentlemen!
Jason Chin in Aarhus
Vitaly and Stephan got on the train to Aarhus to attend a talk by Jason Chin from Cambridge. After a pleasant ride through the beautiful Danish spring, there were treated to an outstanding lecture about the possibilities of using an expanded genetic code to address a wide variety of chemical and biological questions – very inspiring indeed!

Talk in Aachen
No doubt, the hospital of Aachen, Germany has some of the most outrageous architecture imaginable. Not only does the outside look somewhat unique, architects really went to town on the inside, too, where they stuck almost exclusively to green floors, doors and walls – only interspersed by the odd silver wall or neon-colored door. Together, this provided a very unique backdrop to a very inspiring visit and many fruitful discussions with fellow ion channels aficionados that Stephan had the pleasure of meeting. Thank you, Stefan, for a great visit in Aachen!
Say hi to Nina and Matthias
While Matthias embarks on his PhD, Nina will be joining us for her MSc – welcome to the lab! Oh, and their profiles will follow shortly!
He did it again.

Lab summer outing
Motivated by the beautiful summer weather we decided to take to the waters of the harbor for a little self-guided tour of the local attractions. Given we´re in Copenhagen it was only appropriate that we were powered by an über-environmentally friendly outboard engine delivering a whopping 12 V (from solar power-charged batteries, of course). We, on the other hand, were fueled by delicious smørrebrød and local brews, making for fun afternoon out on the water. We certainly hope to be able to make it a summer tradition!
Say hi to Federica
We´re very happy to announce the arrival of our first PhD student, Federica Gasparri! Originally from Milan, Federica just finished her MSc, which including an extended (and very successful) stay at Oxford Brooks.

Attending the annual meeting of the Biophysical Society is always fun, even more so when San Francisco is the host city! Plenty of exciting science, meeting old and new friends and copious amounts of post-conference mix and mingle made for a good mix – looking forward to the 2015 edition (despite that one being hosted by Baltimore – in February)
Congrats to Tim. Again.
Propofol is an intravenous general anesthetic that has recently garnered much attention, not least due to its alleged involvement in the death of a certain King of Pop. Tim now shows how this innocent looking compound can both inhibit and enhance currents through some ligand-gated ion channels – doing so via a single site! See the whole story published as a prestigious Brief Communication in The Journal of Neuroscience.
Congrats to Tim
Tim has been invited as a speaker at the ‘Anthelmintics: From Discorvery to Resistance’ Meeting in San Francisco – congrats!
