However, modeling healthy and pathological aging of the human vasculature represents an unresolved experimental challenge. Here, we generated induced vascular endothelial cells (iVECs) and smooth muscle cells (iSMCs) by direct reprogramming of healthy human fibroblasts from donors of different ages and Hutchinson-Gilford Progeria Syndrome (HGPS) patients. iVECs induced from old donors revealed upregulation of GSTM1 and PALD1, genes linked to oxidative stress, inflammation and endothelial junction stability, as vascular aging markers. A functional assay performed on PALD1 KD VECs demonstrated a recovery in vascular permeability. We found that iSMCs from HGPS donors overexpressed bone morphogenetic protein (BMP)−4, which plays a key role in both vascular calcification and endothelial barrier damage observed in HGPS. Strikingly, BMP4 concentrations are higher in serum from HGPS vs. age-matched mice. Furthermore, targeting BMP4 with blocking antibody recovered the functionality of the vascular barrier in vitro, hence representing a potential future therapeutic strategy to limit cardiovascular dysfunction in HGPS. These results show that iVECs and iSMCs retain disease-related signatures, allowing modeling of vascular aging and HGPS in vitro.","lang":"eng"}],"external_id":{"pmid":["32896271"]},"publisher":"eLife Sciences Publications","_id":"11055","ddc":["570"],"date_published":"2020-09-08T00:00:00Z","article_processing_charge":"No","title":"Direct reprogramming of human smooth muscle and vascular endothelial cells reveals defects associated with aging and Hutchinson-Gilford progeria syndrome","file":[{"creator":"dernst","date_updated":"2022-04-08T06:53:10Z","file_name":"2020_eLife_Bersini.pdf","file_size":4399825,"relation":"main_file","date_created":"2022-04-08T06:53:10Z","access_level":"open_access","checksum":"f8b3821349a194050be02570d8fe7d4b","content_type":"application/pdf","success":1,"file_id":"11132"}],"publication":"eLife","type":"journal_article","publication_identifier":{"issn":["2050-084X"]},"doi":"10.7554/elife.54383","year":"2020","extern":"1","article_number":"e54383","volume":9,"status":"public","date_updated":"2024-10-14T11:17:02Z","scopus_import":"1","keyword":["General Immunology and Microbiology","General Biochemistry","Genetics and Molecular Biology","General Medicine","General Neuroscience"],"oa_version":"Published Version"},{"file_date_updated":"2022-04-08T07:06:05Z","day":"01","publication_status":"published","pmid":1,"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","citation":{"chicago":"Bersini, Simone, Rafael Arrojo e Drigo, Ling Huang, Maxim N.

However, it is largely unknown which factors drive the age-dependent or pathological decline of the vasculature and how vascular defects relate to tissue aging. The goal of the study is to design a multianalytical approach to identify how the cellular microenvironment (i.e., fibroblasts) and serum from healthy donors of different ages or Alzheimer disease (AD) patients can modulate the functionality of organ-specific vascular endothelial cells (VECs). Long-living human microvascular networks embedding VECs and fibroblasts from skin biopsies are generated. RNA-seq, secretome analyses, and microfluidic assays demonstrate that fibroblasts from young donors restore the functionality of aged endothelial cells, an effect also achieved by serum from young donors. New biomarkers of vascular aging are validated in human biopsies and it is shown that young serum induces angiopoietin-like-4, which can restore compromised vascular barriers. This strategy is then employed to characterize transcriptional/functional changes induced on the blood–brain barrier by AD serum, demonstrating the importance of PTP4A3 in the regulation of permeability. Features of vascular degeneration during aging and AD are recapitulated, and a tool to identify novel biomarkers that can be exploited to develop future therapeutics modulating vascular function is established.","lang":"eng"}],"file":[{"file_size":2490829,"relation":"main_file","date_created":"2022-04-08T07:06:05Z","file_name":"2020_AdvancedBiosystems_Bersini.pdf","date_updated":"2022-04-08T07:06:05Z","creator":"dernst","file_id":"11134","content_type":"application/pdf","success":1,"checksum":"5584d9a1609812dc75c02ce1e35d2ec0","access_level":"open_access"}],"publication":"Advanced Biosystems","type":"journal_article","title":"Transcriptional and functional changes of the human microvasculature during physiological aging and Alzheimer disease","article_processing_charge":"No","doi":"10.1002/adbi.202000044","publication_identifier":{"issn":["2366-7478","2366-7478"]},"date_updated":"2024-10-14T11:18:07Z","status":"public","article_number":"2000044","volume":4,"extern":"1","year":"2020","oa_version":"Published Version","keyword":["General Biochemistry","Genetics and Molecular Biology","Biomedical Engineering","Biomaterials"],"issue":"5","scopus_import":"1"},{"volume":34,"year":"2020","extern":"1","date_updated":"2024-10-14T11:18:25Z","status":"public","scopus_import":"1","issue":"13-14","oa_version":"Published Version","keyword":["Developmental Biology","Genetics"],"title":"Dynamic regulation of histone modifications and long-range chromosomal interactions during postmitotic transcriptional reactivation","article_processing_charge":"No","type":"journal_article","publication":"Genes & Development","file":[{"access_level":"open_access","checksum":"84e92d40e67936c739628315c238daf9","content_type":"application/pdf","success":1,"file_id":"11136","creator":"dernst","date_updated":"2022-04-08T07:12:33Z","file_name":"2020_GenesDevelopment_Kang.pdf","date_created":"2022-04-08T07:12:33Z","relation":"main_file","file_size":4406772}],"publication_identifier":{"issn":["0890-9369","1549-5477"]},"doi":"10.1101/gad.335794.119","language":[{"iso":"eng"}],"quality_controlled":"1","tmp":{"image":"/images/cc_by.png","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode"},"date_created":"2022-04-07T07:44:09Z","external_id":{"pmid":["32499403"]},"intvolume":"        34","abstract":[{"text":"During mitosis, transcription of genomic DNA is dramatically reduced, before it is reactivated during nuclear reformation in anaphase/telophase. Many aspects of the underlying principles that mediate transcriptional memory and reactivation in the daughter cells remain unclear. Here, we used ChIP-seq on synchronized cells at different stages after mitosis to generate genome-wide maps of histone modifications. Combined with EU-RNA-seq and Hi-C analyses, we found that during prometaphase, promoters, enhancers, and insulators retain H3K4me3 and H3K4me1, while losing H3K27ac. Enhancers globally retaining mitotic H3K4me1 or locally retaining mitotic H3K27ac are associated with cell type-specific genes and their transcription factors for rapid transcriptional activation. As cells exit mitosis, promoters regain H3K27ac, which correlates with transcriptional reactivation. Insulators also gain H3K27ac and CCCTC-binding factor (CTCF) in anaphase/telophase. This increase of H3K27ac in anaphase/telophase is required for posttranscriptional activation and may play a role in the establishment of topologically associating domains (TADs). Together, our results suggest that the genome is reorganized in a sequential order, in which histone methylations occur first in prometaphase, histone acetylation, and CTCF in anaphase/telophase, transcription in cytokinesis, and long-range chromatin interactions in early G1. We thus provide insights into the histone modification landscape that allows faithful reestablishment of the transcriptional program and TADs during cell division.","lang":"eng"}],"date_published":"2020-04-28T00:00:00Z","publisher":"Cold Spring Harbor Laboratory Press","_id":"11057","ddc":["570"],"day":"28","publication_status":"published","pmid":1,"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","citation":{"short":"H.

However, our knowledge of Nup93 function in breast cancer besides its role as structural component of the nuclear pore complex is not understood. Combination of functional assays and genetic analyses suggested that chromatin interaction of Nup93 partially modulates the expression of genes associated with actin cytoskeleton remodeling and epithelial to mesenchymal transition, resulting in impaired invasion of triple-negative, claudin-low breast cancer cells. Nup93 depletion induced stress fiber formation associated with reduced cell migration/proliferation and impaired expression of mesenchymal-like genes. Silencing LIMCH1, a gene responsible for actin cytoskeleton remodeling and up-regulated upon Nup93 depletion, partially restored the invasive phenotype of cancer cells. Loss of Nup93 led to significant defects in tumor establishment/propagation in vivo, whereas patient samples revealed that high Nup93 and low LIMCH1 expression correlate with late tumor stage. Our approach identified Nup93 as contributor of triple-negative, claudin-low breast cancer cell invasion and paves the way to study the role of nuclear envelope proteins during breast cancer tumorigenesis.","lang":"eng"}],"type":"journal_article","publication":"Life Science Alliance","file":[{"success":1,"content_type":"application/pdf","checksum":"3bf33e7e93bef7823287807206b69b38","access_level":"open_access","file_id":"11137","creator":"dernst","date_created":"2022-04-08T07:33:01Z","relation":"main_file","file_size":2653960,"date_updated":"2022-04-08T07:33:01Z","file_name":"2020_LifeScienceAlliance_Bersini.pdf"}],"title":"Nup93 regulates breast tumor growth by modulating cell proliferation and actin cytoskeleton remodeling","article_processing_charge":"No","doi":"10.26508/lsa.201900623","publication_identifier":{"issn":["2575-1077"]},"date_updated":"2024-10-14T11:18:41Z","status":"public","article_number":"e201900623","volume":3,"year":"2020","extern":"1","oa_version":"Published Version","keyword":["Health","Toxicology and Mutagenesis","Plant Science","Biochemistry","Genetics and Molecular Biology (miscellaneous)","Ecology"],"scopus_import":"1","issue":"1"},{"publisher":"Optica Publishing Group","_id":"10328","oa_version":"None","date_published":"2020-01-01T00:00:00Z","abstract":[{"text":"We discus noise channels in coherent electro-optic up-conversion between microwave and optical fields, in particular due to optical heating.

Here, we develop a coarse-grained model to systematically explore the effect that the structural properties of the lipid membrane and the nature of protein–membrane interactions have on the nucleation rates of amyloid fibrils. We identify two physically distinct nucleation pathways—protein-rich and lipid-rich—and quantify how the membrane fluidity and protein–membrane affinity control the relative importance of those molecular pathways. We find that the membrane’s susceptibility to reshaping and being incorporated into the fibrillar aggregates is a key determinant of its ability to promote protein aggregation. We then characterize the rates and the free-energy profile associated with this heterogeneous nucleation process, in which the surface itself participates in the aggregate structure. Finally, we compare quantitatively our data to experiments on membrane-catalyzed amyloid aggregation of α-synuclein, a protein implicated in Parkinson’s disease that predominately nucleates on membranes. More generally, our results provide a framework for understanding macromolecular aggregation on lipid membranes in a broad biological and biotechnological context.","lang":"eng"}],"intvolume":"       117"},{"oa":1,"article_type":"original","month":"10","page":"10628-10639","citation":{"apa":"Debets, V.

The resulting trajectories are usually consistent with some type of anomalous diffusion, but the molecular origins behind the observed anomalous behaviour are usually not obvious. Here we use coarse-grained molecular dynamics simulations to help identify the physical mechanisms that can give rise to experimentally observed trajectories of nanoscopic objects moving on biological membranes. We find that diffusion on membranes of high fluidities typically results in normal diffusion of the adsorbed nanoparticle, irrespective of the concentration of receptors, receptor clustering, or multivalent interactions between the particle and membrane receptors. Gel-like membranes on the other hand result in anomalous diffusion of the particle, which becomes more pronounced at higher receptor concentrations. This anomalous diffusion is characterised by local particle trapping in the regions of high receptor concentrations and fast hopping between such regions. The normal diffusion is recovered in the limit where the gel membrane is saturated with receptors. We conclude that hindered receptor diffusivity can be a common reason behind the observed anomalous diffusion of viruses, vesicles, and nanoparticles adsorbed on cell and model membranes. Our results enable direct comparison with experiments and offer a new route for interpreting motility experiments on cell membranes."}],"intvolume":"        16","OA_place":"publisher","external_id":{"pmid":["33084724"]},"date_created":"2021-11-26T06:29:41Z","acknowledgement":"We thank Jessica McQuade for her input at the start of the project.

To accomplish this, we combine an evolutionary algorithm with coarse-grained molecular dynamics simulations and explore the solution space of ligand patterns on a nanoparticle that promote efficient and reliable cell uptake. Surprisingly, we find that in the regime of low ligand number the best-performing structures are characterized by ligands arranged into long one-dimensional chains that pattern the surface of the particle. We show that these chains of ligands provide particles with high rotational freedom and they lower the free energy barrier for membrane crossing. Our approach reveals a set of nonintuitive design rules that can be used to inform artificial nanoparticle construction and the search for inhibitors of viral entry.","lang":"eng"}],"intvolume":"       125","OA_place":"publisher","external_id":{"pmid":["33315453"]},"_id":"10344","ddc":["530"],"publisher":"American Physical Society","date_published":"2020-11-23T00:00:00Z","article_processing_charge":"No","title":"Exploring the design rules for efficient membrane-reshaping nanostructures","type":"journal_article","publication":"Physical Review Letters","file":[{"file_id":"10345","access_level":"open_access","checksum":"fbf2e1415e332d6add90222d60401a1d","success":1,"content_type":"application/pdf","date_updated":"2021-11-26T07:16:49Z","file_name":"2020_PhysRevLett_Forster.pdf","file_size":844353,"date_created":"2021-11-26T07:16:49Z","relation":"main_file","creator":"cchlebak"}],"main_file_link":[{"open_access":"1","url":"https://www.biorxiv.org/content/10.1101/2020.02.27.968149v1"}],"publication_identifier":{"eissn":["1079-7114"],"issn":["0031-9007"]},"doi":"10.1103/physrevlett.125.228101","year":"2020","extern":"1","volume":125,"article_number":"228101","status":"public","date_updated":"2024-10-16T12:59:57Z","scopus_import":"1","issue":"22","oa_version":"Published Version"},{"date_updated":"2024-10-16T13:05:34Z","status":"public","volume":119,"year":"2020","extern":"1","oa_version":"Published Version","keyword":["biophysics"],"issue":"9","scopus_import":"1","publication":"Biophysical Journal","type":"journal_article","title":"Modeling fibrillogenesis of collagen-mimetic molecules","article_processing_charge":"No","doi":"10.1016/j.bpj.2020.09.013","publication_identifier":{"issn":["0006-3495"]},"main_file_link":[{"open_access":"1","url":"https://www.biorxiv.org/content/10.1101/2020.06.08.140061v1"}],"acknowledgement":"We thank Melinda Duer, Patrick Mesquida, Lucy Colwell, Lucie Liu, Daan Frenkel, and Ivan Palaia for helpful discussions.

Collagen type I molecules are a crucial component of the extracellular matrix, where they self-assemble into fibrils of well-defined axial striped patterns. This striped fibrillar pattern is preserved across the animal kingdom and is important for the determination of cell phenotype, cell adhesion, and tissue regulation and signaling. The understanding of the physical processes that determine such a robust morphology of self-assembled collagen fibrils is currently almost completely missing. Here, we develop a minimal coarse-grained computational model to identify the physical principles of the assembly of collagen-mimetic molecules. We find that screened electrostatic interactions can drive the formation of collagen-like filaments of well-defined striped morphologies. The fibril axial pattern is determined solely by the distribution of charges on the molecule and is robust to the changes in protein concentration, monomer rigidity, and environmental conditions. We show that the striped fibrillar pattern cannot be easily predicted from the interactions between two monomers but is an emergent result of multibody interactions. Our results can help address collagen remodeling in diseases and aging and guide the design of collagen scaffolds for biotechnological applications."}],"page":"1791-1799","day":"23","OA_type":"hybrid","publication_status":"published","pmid":1,"user_id":"0043cee0-e5fc-11ee-9736-f83bc23afbf0","author":[{"first_name":"Anne E.","last_name":"Hafner","full_name":"Hafner, Anne E."},{"last_name":"Gyori","first_name":"Noemi G.","full_name":"Gyori, Noemi G."},{"full_name":"Bench, Ciaran A.","last_name":"Bench","first_name":"Ciaran A."},{"first_name":"Luke K.","last_name":"Davis","full_name":"Davis, Luke K."},{"orcid":"0000-0002-7854-2139","full_name":"Šarić, Anđela","id":"bf63d406-f056-11eb-b41d-f263a6566d8b","first_name":"Anđela","last_name":"Šarić"}],"citation":{"apa":"Hafner, A.

A fundamental challenge for progress is the range of possible target species and the disparate timescales involved, since the aggregating proteins are simultaneously the reactants, products, intermediates, and catalysts of the reaction. It is a complex problem, therefore, to choose the states of the aggregating proteins that should be bound by the compounds to achieve the most potent inhibition. We present here a comprehensive kinetic theory of amyloid-aggregation inhibition that reveals the fundamental thermodynamic and kinetic signatures characterizing effective inhibitors by identifying quantitative relationships between the aggregation and binding rate constants.

How it breaks membranes, though, remains unknown. Here, we characterize a sequential polymerization of ESCRT-III subunits that, driven by a recruitment cascade and by continuous subunit-turnover powered by the ATPase Vps4, induces membrane deformation and fission. During this process, the exchange of Vps24 for Did2 induces a tilt in the polymer-membrane interface, which triggers transition from flat spiral polymers to helical filament to drive the formation of membrane protrusions, and ends with the formation of a highly constricted Did2-Ist1 co-polymer that we show is competent to promote fission when bound on the inside of membrane necks. Overall, our results suggest a mechanism of stepwise changes in ESCRT-III filament structure and mechanical properties via exchange of the filament subunits to catalyze ESCRT-III activity."}],"date_published":"2020-08-18T00:00:00Z","publisher":"Elsevier","_id":"10348","title":"An ESCRT-III polymerization sequence drives membrane deformation and fission","article_processing_charge":"No","type":"journal_article","publication":"Cell","publication_identifier":{"issn":["0092-8674"]},"main_file_link":[{"url":"https://www.sciencedirect.com/science/article/pii/S0092867420309296","open_access":"1"}],"doi":"10.1016/j.cell.2020.07.021","volume":182,"year":"2020","extern":"1","date_updated":"2021-11-26T08:58:37Z","status":"public","scopus_import":"1","issue":"5","oa_version":"Published Version","keyword":["general biochemistry","genetics and molecular biology"]},{"publication_status":"published","day":"07","citation":{"apa":"Tarrason Risa, G., Hurtig, F., Bray, S., Hafner, A.

Here, in exploring the mechanism of cell division in S. acidocaldarius, we identify a role for the archaeal proteasome in regulating the transition from the end of one cell cycle to the beginning of the next. Further, we identify the archaeal ESCRT-III homolog, CdvB, as a key target of the proteasome and show that its degradation triggers division by allowing constriction of the CdvB1:CdvB2 ESCRT-III division ring. These findings offer a minimal mechanism for ESCRT-III–mediated membrane remodeling and point to a conserved role for the proteasome in eukaryotic and archaeal cell cycle control."}],"intvolume":"       369","publication":"Science","type":"journal_article","title":"The proteasome controls ESCRT-III–mediated cell division in an archaeon","article_processing_charge":"No","doi":"10.1126/science.aaz2532","publication_identifier":{"issn":["0036-8075"],"eissn":["1095-9203"]},"main_file_link":[{"open_access":"1","url":"https://www.biorxiv.org/content/10.1101/774273v1"}],"date_updated":"2021-11-26T08:58:33Z","status":"public","volume":369,"extern":"1","year":"2020","oa_version":"Preprint","keyword":["multidisciplinary"],"issue":"6504","scopus_import":"1"},{"issue":"24","scopus_import":"1","oa_version":"Published Version","keyword":["general chemistry"],"volume":11,"year":"2020","extern":"1","date_updated":"2021-11-26T11:21:20Z","status":"public","publication_identifier":{"issn":["2041-6520"],"eissn":["2041-6539"]},"main_file_link":[{"url":"https://pubs.rsc.org/en/content/articlehtml/2020/sc/c9sc06501f","open_access":"1"}],"license":"https://creativecommons.org/licenses/by-nc/3.0/","doi":"10.1039/c9sc06501f","title":"Identification of on- and off-pathway oligomers in amyloid fibril formation","article_processing_charge":"No","type":"journal_article","publication":"Chemical Science","external_id":{"pmid":["32953019"]},"intvolume":"        11","abstract":[{"lang":"eng","text":"The misfolding and aberrant aggregation of proteins into fibrillar structures is a key factor in some of the most prevalent human diseases, including diabetes and dementia. Low molecular weight oligomers are thought to be a central factor in the pathology of these diseases, as well as critical intermediates in the fibril formation process, and as such have received much recent attention. Moreover, on-pathway oligomeric intermediates are potential targets for therapeutic strategies aimed at interrupting the fibril formation process. However, a consistent framework for distinguishing on-pathway from off-pathway oligomers has hitherto been lacking and, in particular, no consensus definition of on- and off-pathway oligomers is available. In this paper, we argue that a non-binary definition of oligomers' contribution to fibril-forming pathways may be more informative and we suggest a quantitative framework, in which each oligomeric species is assigned a value between 0 and 1 describing its relative contribution to the formation of fibrils. First, we clarify the distinction between oligomers and fibrils, and then we use the formalism of reaction networks to develop a general definition for on-pathway oligomers, that yields meaningful classifications in the context of amyloid formation. By applying these concepts to Monte Carlo simulations of a minimal aggregating system, and by revisiting several previous studies of amyloid oligomers in light of our new framework, we demonstrate how to perform these classifications in practice. For each oligomeric species we obtain the degree to which it is on-pathway, highlighting the most effective pharmaceutical targets for the inhibition of amyloid fibril formation."}],"date_published":"2020-06-08T00:00:00Z","publisher":"Royal Society of Chemistry","_id":"10350","language":[{"iso":"eng"}],"quality_controlled":"1","acknowledgement":"We are grateful to the Schiff Foundation (AJD), Peterhouse, Cambridge (TCTM), the Swiss National Science foundation (TCTM), Ramon Jenkins Fellowship, Sidney Sussex, Cambridge (GM), the Royal Society (AŠ), the Academy of Medical Sciences and Wellcome Trust (AŠ), the Danish Research Council (MK), the Lundbeck Foundation (MK), the Swedish Research Council (SL), the Wellcome Trust (TPJK), the Cambridge Centre for Misfolding Diseases (TPJK), the BBSRC (TPJK), the Frances and Augustus Newman Foundation (TPJK) for financial support.

By developing a general approach that combines theory, experiment and simulation, we reveal, in molecular detail, the mechanisms of Aβ42 oligomer dynamics during amyloid fibril formation. Even though all mature amyloid fibrils must originate as oligomers, we found that most Aβ42 oligomers dissociate into their monomeric precursors without forming new fibrils. Only a minority of oligomers converts into fibrillar structures. Moreover, the heterogeneous ensemble of oligomeric species interconverts on timescales comparable to those of aggregation. Our results identify fundamentally new steps that could be targeted by therapeutic interventions designed to combat protein misfolding diseases."}],"intvolume":"        12","acknowledgement":"We acknowledge support from Peterhouse (T.C.T.M.), the Swiss National Science foundation (T.C.T.M.), the Royal Society (A.Š.), the Academy of Medical Sciences (A.Š.), the UCL Institute for the Physics of Living Systems (S.C.), Sidney Sussex College (G.M.), the Wellcome Trust (A.Š., M.V., C.M.D. and T.P.J.K.), the Schiff Foundation (A.J.D.), the Cambridge Centre for Misfolding Diseases (M.V., C.M.D. and T.P.J.K.), the BBSRC (C.M.D. and T.P.J.K.), the Frances and Augustus Newman Foundation (T.P.J.K.), the Swedish Research Council (S.L.) and the ERC grant MAMBA (S.L., agreement no. 340890).

The collective FG Nup behavior has long been conceptualized either as a polymer brush, dominated by entropic and excluded-volume (repulsive) interactions, or as a hydrogel, dominated by cohesive (attractive) interactions between FG Nups. Here we compare mesoscale computational simulations with a wide range of experimental data to demonstrate that FG Nups are at the crossover point between these two regimes. Specifically, we find that repulsive and attractive interactions are balanced, resulting in morphologies and dynamics that are close to those of ideal polymer chains. We demonstrate that this property of FG Nups yields sufficient cohesion to seal the transport barrier, and yet maintains fast dynamics at the molecular scale, permitting the rapid polymer rearrangements needed for transport events."}],"intvolume":"       101","external_id":{"pmid":["32168597"]}},{"oa":1,"month":"01","article_type":"original","user_id":"8b945eb4-e2f2-11eb-945a-df72226e66a9","pmid":1,"citation":{"ista":"Paraschiv A, Hegde S, Ganti R, Pilizota T, Šarić A. 2020.

By developing a coarse-grained computer model we find that clustering promotes the channel closure, which is highly dependent on the channel concentration and membrane stress. This behaviour yields a tightly regulated gating system, whereby at high tensions channels gate individually, and at lower tensions the channels spontaneously aggregate and inactivate. We implement this positive feedback into the model for cell volume regulation, and find that the channel clustering protects the cell against excessive loss of cytoplasmic content."}],"external_id":{"pmid":["32058787"]},"date_created":"2021-11-26T09:57:01Z","acknowledgement":"We thank Samantha Miller, Bert Poolman, and the members of Šarić and Pilizota laboratories for useful discussion.
