However, the coupling nanotopography at many synapses remains unknown, and it is unclear how it changes during development. To address these questions, we examined coupling at the cerebellar inhibitory basket cell (BC)-Purkinje cell (PC) synapse. Biophysical analysis of transmission by paired recording and intracellular pipette perfusion revealed that the effects of exogenous Ca2+ chelators decreased during development, despite constant reliance of release on P/Q-type Ca2+ channels. Structural analysis by freeze-fracture replica labeling (FRL) and transmission electron microscopy (EM) indicated that presynaptic P/Q-type Ca2+ channels formed nanoclusters throughout development, whereas docked vesicles were only clustered at later developmental stages. Modeling suggested a developmental transformation from a more random to a more clustered coupling nanotopography. Thus, presynaptic signaling developmentally approaches a point-to-point configuration, optimizing speed, reliability, and energy efficiency of synaptic transmission.","lang":"eng"}],"date_updated":"2024-03-05T09:31:24Z","related_material":{"link":[{"description":"News on ISTA Website","url":"https://ista.ac.at/en/news/synapses-brought-to-the-point/","relation":"press_release"}]},"citation":{"ama":"Chen J, Kaufmann W, Chen C, et al.

Here, we show that the actin cortex of leukocytes is mechanoresponsive and that this responsiveness requires neither force sensing via the nucleus nor adhesive interactions with a substrate. Upon global compression of the cell body as well as local indentation of the plasma membrane, Wiskott-Aldrich syndrome protein (WASp) assembles into dot-like structures, providing activation platforms for Arp2/3 nucleated actin patches. These patches locally push against the external load, which can be obstructing collagen fibers or other cells, and thereby create space to facilitate forward locomotion. We show in vitro and in vivo that this WASp function is rate limiting for ameboid leukocyte migration in dense but not in loose environments and is required for trafficking through diverse tissues such as skin and lymph nodes."}],"date_updated":"2024-03-25T23:30:12Z","oa_version":"Published Version","type":"journal_article","month":"01","page":"47-62.e9","_id":"10703","year":"2022","acknowledgement":"We thank N.

The level of cortical tension outside of the cell–cell contact, when pulling at the contact edge, scales with the total size to which a cell–cell contact can grow [J.-L. Maître et al., Science 338, 253–256 (2012)]. Here, we show in zebrafish primary germ-layer progenitor cells that this monotonic relationship only applies to a narrow range of cortical tension increase and that above a critical threshold, contact size inversely scales with cortical tension. This switch from cortical tension increasing to decreasing progenitor cell–cell contact size is caused by cortical tension promoting E-cadherin anchoring to the actomyosin cytoskeleton, thereby increasing clustering and stability of E-cadherin at the contact. After tension-mediated E-cadherin stabilization at the contact exceeds a critical threshold level, the rate by which the contact expands in response to pulling forces from the cortex sharply drops, leading to smaller contacts at physiologically relevant timescales of contact formation. Thus, the activity of cortical tension in expanding cell–cell contact size is limited by tension-stabilizing E-cadherin–actin complexes at the contact.","lang":"eng"}],"month":"02","oa_version":"Published Version","type":"journal_article","volume":119,"date_created":"2022-02-20T23:01:31Z","file_date_updated":"2022-02-21T08:45:11Z","acknowledgement":"We thank Guillaume Salbreaux, Silvia Grigolon, Edouard Hannezo, and Vanessa Barone for discussions and comments on the manuscript and Shayan Shamipour and Daniel Capek for help with data analysis.

vesicles (CCVs) facilitate the internalization of material from the cell surface as well as the movement of cargo in post-Golgi trafficking pathways. This diversity of functions is partially provided by multiple monomeric and multimeric clathrin adaptor complexes that provide compartment and cargo selectivity. The adaptor-protein assembly polypeptide-1 (AP-1) complex operates as part of the secretory pathway at the trans-Golgi network (TGN), while the AP-2 complex and the TPLATE complex jointly operate at the plasma membrane to execute clathrin-mediated endocytosis. Key to our further understanding of clathrin-mediated trafficking in plants will be the comprehensive identification and characterization of the network of evolutionarily conserved and plant-specific core and accessory machinery involved in the formation and targeting of CCVs. To facilitate these studies, we have analyzed the proteome of enriched TGN/early endosome-derived and endocytic CCVs isolated from dividing and expanding suspension-cultured Arabidopsis (Arabidopsis thaliana) cells. Tandem mass spectrometry analysis results were validated by differential chemical labeling experiments to identify proteins co-enriching with CCVs. Proteins enriched in CCVs included previously characterized CCV components and cargos such as the vacuolar sorting receptors in addition to conserved and plant-specific components whose function in clathrin-mediated trafficking has not been previously defined. Notably, in addition to AP-1 and AP-2, all subunits of the AP-4 complex, but not AP-3 or AP-5, were found to be in high abundance in the CCV proteome. The association of AP-4 with suspension-cultured Arabidopsis CCVs is further supported via additional biochemical data.","lang":"eng"}],"date_updated":"2023-08-02T14:46:48Z","type":"journal_article","month":"06","oa_version":"Preprint","_id":"10841","acknowledgement":"The authors would like to acknowledge the VIB Proteomics Core Facility (VIB-UGent Center for Medical Biotechnology in Ghent, Belgium) and the Research Technology Support Facility Proteomics Core (Michigan State University in East Lansing, Michigan) for sample analysis, as well as the University of Wisconsin Biotechnology Center Mass Spectrometry Core Facility (Madison, WI) for help with data processing.

Therefore, it is critical to study biological structures in 3D and at high resolution to gain insights into their physiological functions. Electron microscopy of metal replicas of unroofed cells and isolated organelles has been a key technique to visualize intracellular structures at nanometer resolution. However, many of these methods require specialized equipment and personnel to complete them. Here, we present novel accessible methods to analyze biological structures in unroofed cells and biochemically isolated organelles in 3D and at nanometer resolution, focusing on Arabidopsis clathrin-coated vesicles (CCVs). While CCVs are essential trafficking organelles, their detailed structural information is lacking due to their poor preservation when observed via classical electron microscopy protocols experiments. First, we establish a method to visualize CCVs in unroofed cells using scanning transmission electron microscopy tomography, providing sufficient resolution to define the clathrin coat arrangements. Critically, the samples are prepared directly on electron microscopy grids, removing the requirement to use extremely corrosive acids, thereby enabling the use of this method in any electron microscopy lab. Secondly, we demonstrate that this standardized sample preparation allows the direct comparison of isolated CCV samples with those visualized in cells. Finally, to facilitate the high-throughput and robust screening of metal replicated samples, we provide a deep learning analysis method to screen the “pseudo 3D” morphologies of CCVs imaged with 2D modalities. Collectively, our work establishes accessible ways to examine the 3D structure of biological samples and provide novel insights into the structure of plant CCVs.","lang":"eng"}],"date_updated":"2023-08-04T09:39:24Z","oa_version":"Published Version","type":"journal_article","month":"10","volume":15,"date_created":"2023-01-16T09:51:49Z","file_date_updated":"2023-01-30T07:46:51Z","project":[{"name":"Molecular mechanisms of endocytic cargo recognition in plants","call_identifier":"FWF","_id":"26538374-B435-11E9-9278-68D0E5697425","grant_number":"I03630"}],"isi":1,"keyword":["Plant Science","Molecular Biology"],"language":[{"iso":"eng"}],"issue":"10","publication_identifier":{"issn":["1674-2052"]},"doi":"10.1016/j.molp.2022.09.003","quality_controlled":"1","publisher":"Elsevier","user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","pmid":1,"department":[{"_id":"JiFr"},{"_id":"EM-Fac"},{"_id":"Bio"}],"publication":"Molecular Plant","scopus_import":"1","article_processing_charge":"Yes (via OA deal)","article_type":"original","tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","image":"/images/cc_by.png","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)"},"author":[{"first_name":"Alexander J","last_name":"Johnson","full_name":"Johnson, Alexander J","id":"46A62C3A-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-2739-8843"},{"full_name":"Kaufmann, Walter","orcid":"0000-0001-9735-5315","id":"3F99E422-F248-11E8-B48F-1D18A9856A87","first_name":"Walter","last_name":"Kaufmann"},{"first_name":"Christoph M","last_name":"Sommer","full_name":"Sommer, Christoph M","id":"4DF26D8C-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0003-1216-9105"},{"orcid":"0000-0001-9732-3815","id":"D93824F4-D9BA-11E9-BB12-F207E6697425","full_name":"Costanzo, Tommaso","first_name":"Tommaso","last_name":"Costanzo"},{"last_name":"Dahhan","first_name":"Dana A.","full_name":"Dahhan, Dana A."},{"full_name":"Bednarek, Sebastian Y.","first_name":"Sebastian Y.","last_name":"Bednarek"},{"first_name":"Jiří","last_name":"Friml","full_name":"Friml, Jiří","orcid":"0000-0002-8302-7596","id":"4159519E-F248-11E8-B48F-1D18A9856A87"}],"file":[{"checksum":"04d5c12490052d03e4dc4412338a43dd","date_updated":"2023-01-30T07:46:51Z","file_id":"12435","access_level":"open_access","date_created":"2023-01-30T07:46:51Z","success":1,"file_name":"2022_MolecularPlant_Johnson.pdf","creator":"dernst","relation":"main_file","content_type":"application/pdf","file_size":2307251}],"day":"03","title":"Three-dimensional visualization of planta clathrin-coated vesicles at ultrastructural resolution"},{"date_updated":"2023-11-07T08:16:09Z","abstract":[{"text":"The phytohormone auxin triggers transcriptional reprogramming through a well-characterized perception machinery in the nucleus. By contrast, mechanisms that underlie fast effects of auxin, such as the regulation of ion fluxes, rapid phosphorylation of proteins or auxin feedback on its transport, remain unclear1,2,3. Whether auxin-binding protein 1 (ABP1) is an auxin receptor has been a source of debate for decades1,4. Here we show that a fraction of Arabidopsis thaliana ABP1 is secreted and binds auxin specifically at an acidic pH that is typical of the apoplast. ABP1 and its plasma-membrane-localized partner, transmembrane kinase 1 (TMK1), are required for the auxin-induced ultrafast global phospho-response and for downstream processes that include the activation of H+-ATPase and accelerated cytoplasmic streaming. abp1 and tmk mutants cannot establish auxin-transporting channels and show defective auxin-induced vasculature formation and regeneration. An ABP1(M2X) variant that lacks the capacity to bind auxin is unable to complement these defects in abp1 mutants. These data indicate that ABP1 is the auxin receptor for TMK1-based cell-surface signalling, which mediates the global phospho-response and auxin canalization.","lang":"eng"}],"type":"journal_article","month":"09","oa_version":"Submitted Version","page":"575-581","date_created":"2023-01-16T10:04:48Z","file_date_updated":"2023-11-02T17:12:37Z","volume":609,"year":"2022","acknowledgement":"We acknowledge K.

Immunological challenge causes LNs to increase more than tenfold in size within a few days. Here, we characterized the biomechanics of LN swelling on the cellular and organ scale. We identified lymphocyte trapping by influx and proliferation as drivers of an outward pressure force, causing fibroblastic reticular cells of the T-zone (TRCs) and their associated conduits to stretch. After an initial phase of relaxation, TRCs sensed the resulting strain through cell matrix adhesions, which coordinated local growth and remodeling of the stromal network. While the expanded TRC network readopted its typical configuration, a massive fibrotic reaction of the organ capsule set in and countered further organ expansion. Thus, different fibroblast populations mechanically control LN swelling in a multitier fashion."}],"date_updated":"2023-08-02T06:53:07Z","_id":"9794","acknowledgement":"This research was supported by the Scientific Service Units of IST Austria through resources provided by the Imaging and Optics, Electron Microscopy, Preclinical and Life Science Facilities.

The polar, cellular localization of Arabidopsis PIN‐FORMED (PIN) proteins is crucial for their function in directional auxin transport. The clustering of PIN polar cargoes within the plasma membrane has been proposed to be important for the maintenance of their polar distribution. However, the more detailed features of PIN clusters and the cellular requirements of cargo clustering remain unclear.\r\nHere, we characterized PIN clusters in detail by means of multiple advanced microscopy and quantification methods, such as 3D quantitative imaging or freeze‐fracture replica labeling. The size and aggregation types of PIN clusters were determined by electron microscopy at the nanometer level at different polar domains and at different developmental stages, revealing a strong preference for clustering at the polar domains.\r\nPharmacological and genetic studies revealed that PIN clusters depend on phosphoinositol pathways, cytoskeletal structures and specific cell‐wall components as well as connections between the cell wall and the plasma membrane.\r\nThis study identifies the role of different cellular processes and structures in polar cargo clustering and provides initial mechanistic insight into the maintenance of polarity in plants and other systems."}],"date_updated":"2023-08-04T11:01:21Z","page":"351-369","_id":"8582","year":"2021","acknowledgement":"We thank Dr Ingo Heilmann (Martin‐Luther‐University Halle‐Wittenberg) for the XVE>>PIP5K1‐YFP line, Dr Brad Day (Michigan State University) for the ndr1‐1 mutant and the complementation lines, and Dr Patricia C.

Here we show that α2δ subunits are essential for the formation and organization of glutamatergic synapses. Using a cellular α2δ subunit triple-knockout/knockdown model, we demonstrate a failure in presynaptic differentiation evidenced by defective presynaptic calcium channel clustering and calcium influx, smaller presynaptic active zones, and a strongly reduced accumulation of presynaptic vesicle-associated proteins (synapsin and vGLUT). The presynaptic defect is associated with the downscaling of postsynaptic AMPA receptors and the postsynaptic density. The role of α2δ isoforms as synaptic organizers is highly redundant, as each individual α2δ isoform can rescue presynaptic calcium channel trafficking and expression of synaptic proteins. Moreover, α2δ-2 and α2δ-3 with mutated metal ion-dependent adhesion sites can fully rescue presynaptic synapsin expression but only partially calcium channel trafficking, suggesting that the regulatory role of α2δ subunits is independent from its role as a calcium channel subunit. Our findings influence the current view on excitatory synapse formation. First, our study suggests that postsynaptic differentiation is secondary to presynaptic differentiation. Second, the dependence of presynaptic differentiation on α2δ implicates α2δ subunits as potential nucleation points for the organization of synapses. Finally, our results suggest that α2δ subunits act as transsynaptic organizers of glutamatergic synapses, thereby aligning the synaptic active zone with the postsynaptic density.","lang":"eng"}],"date_updated":"2023-08-08T13:08:47Z","month":"04","type":"journal_article","oa_version":"Published Version","volume":118,"date_created":"2021-04-18T22:01:40Z","file_date_updated":"2021-04-19T10:10:56Z","acknowledgement":"We thank Arnold Schwartz for providing α2δ-1 knockout mice; Ariane Benedetti, Sabine Baumgartner, Sandra Demetz, and Irene Mahlknecht for technical support; Nadine Ortner and Andreas Lieb for electrophysiological experiments; the team of the Electron Microscopy Facility at the Institute of Science and Technology Austria for technical support related to ultrastructural analysis; Hermann Dietrich and Anja Beierfuß and her team for animal care; Jutta Engel and Jörg Striessnig for critical discussions; and Bruno Benedetti and Bernhard Flucher for critical discussions and reading the manuscript.

Experimental data suggest that microglial TLR4 mediates the uptake and clearance of α-synuclein also termed synucleinophagy. The accumulation of misfolded α-synuclein throughout the brain is central to Parkinson's disease (PD). The distribution and progression of the pathology is often attributed to the propagation of α-synuclein. Here, we apply a classical α-synuclein propagation model of prodromal PD in wild type and TLR4 deficient mice to study the role of TLR4 in the progression of the disease. Our data suggest that TLR4 deficiency facilitates the α-synuclein seed spreading associated with reduced lysosomal activity of microglia. Three months after seed inoculation, more pronounced proteinase K-resistant α-synuclein inclusion pathology is observed in mice with TLR4 deficiency. The facilitated propagation of α-synuclein is associated with early loss of dopamine transporter (DAT) signal in the striatum and loss of dopaminergic neurons in substantia nigra pars compacta of TLR4 deficient mice. These new results support TLR4 signaling as a putative target for disease modification to slow the progression of PD and related disorders.","lang":"eng"}],"oa_version":"Published Version","month":"10","type":"journal_article","page":"59-65"},{"publication":" Receptor and Ion Channel Detection in the Brain","ec_funded":1,"article_processing_charge":"No","user_id":"D865714E-FA4E-11E9-B85B-F5C5E5697425","publisher":"Humana","department":[{"_id":"RySh"},{"_id":"EM-Fac"}],"place":"New York","title":"High-Resolution localization and quantitation of membrane proteins by SDS-digested freeze-fracture replica labeling (SDS-FRL)","author":[{"first_name":"Walter","last_name":"Kaufmann","orcid":"0000-0001-9735-5315","id":"3F99E422-F248-11E8-B48F-1D18A9856A87","full_name":"Kaufmann, Walter"},{"id":"42E121A4-F248-11E8-B48F-1D18A9856A87","full_name":"Kleindienst, David","first_name":"David","last_name":"Kleindienst"},{"last_name":"Harada","first_name":"Harumi","full_name":"Harada, Harumi","orcid":"0000-0001-7429-7896","id":"2E55CDF2-F248-11E8-B48F-1D18A9856A87"},{"last_name":"Shigemoto","first_name":"Ryuichi","full_name":"Shigemoto, Ryuichi","orcid":"0000-0001-8761-9444","id":"499F3ABC-F248-11E8-B48F-1D18A9856A87"}],"day":"27","keyword":["Freeze-fracture replica: Deep learning","Immunogold labeling","Integral membrane protein","Electron microscopy"],"series_title":"Neuromethods","language":[{"iso":"eng"}],"project":[{"name":"In situ analysis of single channel subunit composition in neurons: physiological implication in synaptic plasticity and behaviour","_id":"25CA28EA-B435-11E9-9278-68D0E5697425","call_identifier":"H2020","grant_number":"694539"},{"grant_number":"720270","_id":"25CBA828-B435-11E9-9278-68D0E5697425","call_identifier":"H2020","name":"Human Brain Project Specific Grant Agreement 1 (HBP SGA 1)"}],"doi":"10.1007/978-1-0716-1522-5_19","quality_controlled":"1","publication_identifier":{"isbn":["9781071615218"],"eisbn":["9781071615225"]},"_id":"9756","acknowledgement":"This work was supported by the European Union (European Research Council Advanced grant no. 694539 and Human Brain Project Ref. 720270 to R.

During treatment with SDS, intracellular organelles and proteins not anchored to the replica are dissolved, whereas integral membrane proteins captured and stabilized by carbon/platinum deposition remain on the replica. Their intra- and extracellular domains become exposed on the surface of the replica, facilitating the accessibility of antibodies and, therefore, providing higher labeling efficiency than those obtained with other immunoelectron microscopy techniques.

During endocytosis, an area of flat membrane is remodeled by proteins to create a spherical vesicle against intracellular forces. The protein machinery which mediates this membrane bending in plants is unknown. However, it is known that plant endocytosis is actin independent, thus indicating that plants utilize a unique mechanism to mediate membrane bending against high-turgor pressure compared to other model systems. Here, we investigate the TPLATE complex, a plant-specific endocytosis protein complex. It has been thought to function as a classical adaptor functioning underneath the clathrin coat. However, by using biochemical and advanced live microscopy approaches, we found that TPLATE is peripherally associated with clathrin-coated vesicles and localizes at the rim of endocytosis events. As this localization is more fitting to the protein machinery involved in membrane bending during endocytosis, we examined cells in which the TPLATE complex was disrupted and found that the clathrin structures present as flat patches. This suggests a requirement of the TPLATE complex for membrane bending during plant clathrin–mediated endocytosis. Next, we used in vitro biophysical assays to confirm that the TPLATE complex possesses protein domains with intrinsic membrane remodeling activity. These results redefine the role of the TPLATE complex and implicate it as a key component of the evolutionarily distinct plant endocytosis mechanism, which mediates endocytic membrane bending against the high-turgor pressure in plant cells.","lang":"eng"}],"oa_version":"Published Version","month":"12","type":"journal_article","_id":"9887","acknowledgement":"We gratefully thank Julie Neveu and Dr. Amanda Barranco of the Grégory Vert laboratory for help preparing plants in France, Dr. Zuzana Gelova for help and advice with protoplast generation, Dr. Stéphane Vassilopoulos and Dr. Florian Schur for advice regarding EM tomography, Alejandro Marquiegui Alvaro for help with material generation, and Dr. Lukasz Kowalski for generously gifting us the mWasabi protein.

It has been assumed to operate in an evolutionary conserved manner as in yeast and animals. Here we report characterisation of ultrastructure, dynamics and mechanisms of plant CME as allowed by our advancement in electron microscopy and quantitative live imaging techniques. Arabidopsis CME appears to follow the constant curvature model and the bona fide CME population generates vesicles of a predominantly hexagonal-basket type; larger and with faster kinetics than in other models. Contrary to the existing paradigm, actin is dispensable for CME events at the plasma membrane but plays a unique role in collecting endocytic vesicles, sorting of internalised cargos and directional endosome movement that itself actively promote CME events. Internalized vesicles display a strongly delayed and sequential uncoating. These unique features highlight the independent evolution of the plant CME mechanism during the autonomous rise of multicellularity in eukaryotes."}],"date_updated":"2023-08-18T06:33:07Z","volume":9,"file_date_updated":"2020-07-14T12:47:59Z","date_created":"2020-02-16T23:00:50Z","project":[{"grant_number":"742985","name":"Tracing Evolution of Auxin Transport and Polarity in Plants","call_identifier":"H2020","_id":"261099A6-B435-11E9-9278-68D0E5697425"},{"name":"Molecular mechanisms of endocytic cargo recognition in plants","call_identifier":"FWF","_id":"26538374-B435-11E9-9278-68D0E5697425","grant_number":"I03630"}],"isi":1,"language":[{"iso":"eng"}],"publication_identifier":{"eissn":["2050-084X"]},"doi":"10.7554/eLife.52067","quality_controlled":"1","publisher":"eLife Sciences Publications","user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","department":[{"_id":"JiFr"},{"_id":"GaTk"},{"_id":"EM-Fac"},{"_id":"SyCr"}],"pmid":1,"publication":"eLife","tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","image":"/images/cc_by.png","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)"},"article_type":"original","scopus_import":"1","article_processing_charge":"No","ec_funded":1,"author":[{"last_name":"Narasimhan","first_name":"Madhumitha","full_name":"Narasimhan, Madhumitha","orcid":"0000-0002-8600-0671","id":"44BF24D0-F248-11E8-B48F-1D18A9856A87"},{"full_name":"Johnson, Alexander J","id":"46A62C3A-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-2739-8843","first_name":"Alexander J","last_name":"Johnson"},{"first_name":"Roshan","last_name":"Prizak","full_name":"Prizak, Roshan","id":"4456104E-F248-11E8-B48F-1D18A9856A87"},{"full_name":"Kaufmann, Walter","id":"3F99E422-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0001-9735-5315","last_name":"Kaufmann","first_name":"Walter"},{"id":"2DE75584-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-0471-8285","full_name":"Tan, Shutang","last_name":"Tan","first_name":"Shutang"},{"id":"351ED2AA-F248-11E8-B48F-1D18A9856A87","full_name":"Casillas Perez, Barbara E","last_name":"Casillas Perez","first_name":"Barbara E"},{"first_name":"Jiří","last_name":"Friml","full_name":"Friml, Jiří","orcid":"0000-0002-8302-7596","id":"4159519E-F248-11E8-B48F-1D18A9856A87"}],"file":[{"date_created":"2020-02-18T07:21:16Z","access_level":"open_access","file_id":"7494","date_updated":"2020-07-14T12:47:59Z","checksum":"2052daa4be5019534f3a42f200a09f32","file_size":7247468,"relation":"main_file","content_type":"application/pdf","creator":"dernst","file_name":"2020_eLife_Narasimhan.pdf"}],"day":"23","article_number":"e52067","title":"Evolutionarily unique mechanistic framework of clathrin-mediated endocytosis in plants"},{"project":[{"name":"International IST Postdoc Fellowship Programme","call_identifier":"FP7","_id":"25681D80-B435-11E9-9278-68D0E5697425","grant_number":"291734"},{"grant_number":"742573","name":"Interaction and feedback between cell mechanics and fate specification in vertebrate gastrulation","call_identifier":"H2020","_id":"260F1432-B435-11E9-9278-68D0E5697425"},{"_id":"2521E28E-B435-11E9-9278-68D0E5697425","name":"Modulation of adhesion function in cell-cell contact formation by cortical tension","grant_number":"187-2013"}],"status":"public","related_material":{"record":[{"status":"public","id":"10766","relation":"later_version"},{"status":"public","id":"9623","relation":"dissertation_contains"}]},"language":[{"iso":"eng"}],"citation":{"ieee":"J.

The level of cortical tension outside of the cell-cell contact, when pulling at the contact edge, scales with the total size to which a cell-cell contact can grow1,2. Here we show in zebrafish primary germ layer progenitor cells that this monotonic relationship only applies to a narrow range of cortical tension increase, and that above a critical threshold, contact size inversely scales with cortical tension. This switch from cortical tension increasing to decreasing progenitor cell-cell contact size is caused by cortical tension promoting E-cadherin anchoring to the actomyosin cytoskeleton, thereby increasing clustering and stability of E-cadherin at the contact. Once tension-mediated E-cadherin stabilization at the contact exceeds a critical threshold level, the rate by which the contact expands in response to pulling forces from the cortex sharply drops, leading to smaller contacts at physiologically relevant timescales of contact formation. Thus, the activity of cortical tension in expanding cell-cell contact size is limited by tension stabilizing E-cadherin-actin complexes at the contact."}],"title":"Tension-dependent stabilization of E-cadherin limits cell-cell contact expansion","date_created":"2021-07-29T11:29:50Z"},{"quality_controlled":"1","doi":"10.1016/j.devcel.2018.04.002","project":[{"name":"Drosophila TNFa´s Funktion in Immunzellen","call_identifier":"FWF","_id":"253B6E48-B435-11E9-9278-68D0E5697425","grant_number":"P29638"},{"_id":"2536F660-B435-11E9-9278-68D0E5697425","call_identifier":"FP7","name":"Investigating the role of transporters in invasive migration through junctions","grant_number":"334077"}],"issue":"3","language":[{"iso":"eng"}],"isi":1,"day":"07","author":[{"full_name":"Ratheesh, Aparna","id":"2F064CFE-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0001-7190-0776","last_name":"Ratheesh","first_name":"Aparna"},{"id":"3CCBB46E-F248-11E8-B48F-1D18A9856A87","full_name":"Biebl, Julia","first_name":"Julia","last_name":"Biebl"},{"last_name":"Smutny","first_name":"Michael","full_name":"Smutny, Michael"},{"last_name":"Veselá","first_name":"Jana","full_name":"Veselá, Jana","id":"433253EE-F248-11E8-B48F-1D18A9856A87"},{"first_name":"Ekaterina","last_name":"Papusheva","full_name":"Papusheva, Ekaterina","id":"41DB591E-F248-11E8-B48F-1D18A9856A87"},{"last_name":"Krens","first_name":"Gabriel","full_name":"Krens, Gabriel","id":"2B819732-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0003-4761-5996"},{"orcid":"0000-0001-9735-5315","id":"3F99E422-F248-11E8-B48F-1D18A9856A87","full_name":"Kaufmann, Walter","first_name":"Walter","last_name":"Kaufmann"},{"last_name":"György","first_name":"Attila","orcid":"0000-0002-1819-198X","id":"3BCEDBE0-F248-11E8-B48F-1D18A9856A87","full_name":"György, Attila"},{"full_name":"Casano, Alessandra M","id":"3DBA3F4E-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-6009-6804","first_name":"Alessandra M","last_name":"Casano"},{"full_name":"Siekhaus, Daria E","id":"3D224B9E-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0001-8323-8353","last_name":"Siekhaus","first_name":"Daria E"}],"title":"Drosophila TNF modulates tissue tension in the embryo to facilitate macrophage invasive migration","department":[{"_id":"DaSi"},{"_id":"CaHe"},{"_id":"Bio"},{"_id":"EM-Fac"},{"_id":"MiSi"}],"pmid":1,"publisher":"Elsevier","user_id":"c635000d-4b10-11ee-a964-aac5a93f6ac1","article_type":"original","scopus_import":"1","ec_funded":1,"article_processing_charge":"No","publication":"Developmental Cell","publication_status":"published","oa":1,"acknowledged_ssus":[{"_id":"SSU"}],"main_file_link":[{"open_access":"1","url":"https://doi.org/10.1016/j.devcel.2018.04.002"}],"date_published":"2018-05-07T00:00:00Z","external_id":{"isi":["000432461400009"],"pmid":["29738712"]},"status":"public","citation":{"ama":"Ratheesh A, Bicher J, Smutny M, et al.

We find that macrophage invasion into the germband through transient separation of the apposing ectoderm and mesoderm requires cell deformations and reductions in apical tension in the ectoderm. Interestingly, the genetic pathway governing these mechanical shifts acts downstream of the only known tumor necrosis factor superfamily member in Drosophila, Eiger, and its receptor, Grindelwald. Eiger-Grindelwald signaling reduces levels of active Myosin in the germband ectodermal cortex through the localization of a Crumbs complex component, Patj (Pals-1-associated tight junction protein).

After HPF, samples are maintained at low temperature during dehydration and fixation, while avoiding damaging recrystallization. This is a notoriously slow process. McDonald and Webb demonstrated, in 2011, that sample agitation during FS dramatically reduces the necessary time. Then, in 2015, we (H.G. and S.R.) introduced an agitation module into the cryochamber of an automated FS unit and demonstrated that the preparation of algae could be shortened from days to a couple of hours. We argued that variability in the processing, reproducibility, and safety issues are better addressed using automated FS units. For dissemination, we started low-cost manufacturing of agitation modules for two of the most widely used FS units, the Automatic Freeze Substitution Systems, AFS(1) and AFS2, from Leica Microsystems, using three dimensional (3D)-printing of the major components. To test them, several labs independently used the modules on a wide variety of specimens that had previously been processed by manual agitation, or without agitation. We demonstrate that automated processing with sample agitation saves time, increases flexibility with respect to sample requirements and protocols, and produces data of at least as good quality as other approaches.","lang":"eng"}],"date_updated":"2023-10-17T08:42:24Z"},{"pubrep_id":"900","publication_identifier":{"issn":["22111247"]},"quality_controlled":"1","doi":"10.1016/j.celrep.2017.04.027","project":[{"grant_number":"281556","name":"Cytoskeletal force generation and force transduction of migrating leukocytes (EU)","call_identifier":"FP7","_id":"25A603A2-B435-11E9-9278-68D0E5697425"},{"name":"Cytoskeletal force generation and transduction of leukocytes (FWF)","call_identifier":"FWF","_id":"25A8E5EA-B435-11E9-9278-68D0E5697425","grant_number":"Y 564-B12"}],"issue":"5","language":[{"iso":"eng"}],"file":[{"checksum":"8fdddaab1f1d76a6ec9ca94dcb6b07a2","file_id":"5109","date_updated":"2020-07-14T12:47:38Z","access_level":"open_access","date_created":"2018-12-12T10:14:54Z","file_name":"IST-2017-900-v1+1_1-s2.0-S2211124717305211-main.pdf","creator":"system","file_size":2248814,"relation":"main_file","content_type":"application/pdf"}],"day":"02","author":[{"full_name":"Vaahtomeri, Kari","id":"368EE576-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0001-7829-3518","first_name":"Kari","last_name":"Vaahtomeri"},{"last_name":"Brown","first_name":"Markus","id":"3DAB9AFC-F248-11E8-B48F-1D18A9856A87","full_name":"Brown, Markus"},{"full_name":"Hauschild, Robert","id":"4E01D6B4-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0001-9843-3522","first_name":"Robert","last_name":"Hauschild"},{"full_name":"De Vries, Ingrid","id":"4C7D837E-F248-11E8-B48F-1D18A9856A87","first_name":"Ingrid","last_name":"De Vries"},{"first_name":"Alexander F","last_name":"Leithner","full_name":"Leithner, Alexander F","id":"3B1B77E4-F248-11E8-B48F-1D18A9856A87"},{"last_name":"Mehling","first_name":"Matthias","id":"3C23B994-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0001-8599-1226","full_name":"Mehling, Matthias"},{"last_name":"Kaufmann","first_name":"Walter","orcid":"0000-0001-9735-5315","id":"3F99E422-F248-11E8-B48F-1D18A9856A87","full_name":"Kaufmann, Walter"},{"first_name":"Michael K","last_name":"Sixt","full_name":"Sixt, Michael K","id":"41E9FBEA-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-6620-9179"}],"publist_id":"7052","title":"Locally triggered release of the chemokine CCL21 promotes dendritic cell transmigration across lymphatic endothelia","department":[{"_id":"MiSi"},{"_id":"Bio"},{"_id":"EM-Fac"}],"user_id":"3E5EF7F0-F248-11E8-B48F-1D18A9856A87","publisher":"Cell Press","tmp":{"name":"Creative Commons Attribution-NonCommercial-NoDerivatives 4.0 International (CC BY-NC-ND 4.0)","short":"CC BY-NC-ND (4.0)","image":"/images/cc_by_nc_nd.png","legal_code_url":"https://creativecommons.org/licenses/by-nc-nd/4.0/legalcode"},"article_processing_charge":"Yes","scopus_import":1,"ec_funded":1,"publication":"Cell Reports","has_accepted_license":"1","publication_status":"published","oa":1,"date_published":"2017-05-02T00:00:00Z","ddc":["570"],"status":"public","citation":{"short":"K.

Upon DC transmigration, these Golgi deposits disperse and CCL21 becomes extracellularly enriched at the sites of endothelial cell-cell junctions. When we reconstitute the transmigration process in vitro, we find that secretion of CCL21-positive vesicles is triggered by a DC contact-induced calcium signal, and selective calcium chelation in lymphatic endothelium attenuates transmigration. Altogether, our data demonstrate a chemokine-mediated feedback between DCs and lymphatic endothelium, which facilitates transendothelial migration."}],"date_updated":"2023-02-23T12:50:09Z","page":"902 - 909","file_date_updated":"2020-07-14T12:47:38Z","date_created":"2018-12-11T11:47:50Z","volume":19,"year":"2017","_id":"672"},{"issue":"26","language":[{"iso":"eng"}],"doi":"10.1073/pnas.1704470114","quality_controlled":"1","publication_identifier":{"issn":["00278424"]},"publication":"PNAS","article_processing_charge":"Yes (in subscription journal)","scopus_import":1,"publisher":"National Academy of Sciences","user_id":"3E5EF7F0-F248-11E8-B48F-1D18A9856A87","department":[{"_id":"EM-Fac"},{"_id":"RySh"}],"pmid":1,"title":"Numbers of presynaptic Ca2+ channel clusters match those of functionally defined vesicular docking sites in single central synapses","publist_id":"7013","author":[{"first_name":"Takafumi","last_name":"Miki","full_name":"Miki, Takafumi"},{"full_name":"Kaufmann, Walter","id":"3F99E422-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0001-9735-5315","last_name":"Kaufmann","first_name":"Walter"},{"first_name":"Gerardo","last_name":"Malagon","full_name":"Malagon, Gerardo"},{"first_name":"Laura","last_name":"Gomez","full_name":"Gomez, Laura"},{"full_name":"Tabuchi, Katsuhiko","first_name":"Katsuhiko","last_name":"Tabuchi"},{"full_name":"Watanabe, Masahiko","first_name":"Masahiko","last_name":"Watanabe"},{"full_name":"Shigemoto, Ryuichi","id":"499F3ABC-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0001-8761-9444","last_name":"Shigemoto","first_name":"Ryuichi"},{"full_name":"Marty, Alain","last_name":"Marty","first_name":"Alain"}],"day":"27","file":[{"date_created":"2020-01-03T13:27:29Z","access_level":"open_access","file_id":"7223","date_updated":"2020-07-14T12:47:44Z","checksum":"2ab75d554f3df4a34d20fa8040589b7e","file_size":2721544,"content_type":"application/pdf","relation":"main_file","creator":"kschuh","file_name":"2017_PNAS_Miki.pdf"}],"intvolume":"       114","citation":{"apa":"Miki, T., Kaufmann, W., Malagon, G., Gomez, L., Tabuchi, K., Watanabe, M., … Marty, A.

Vesicular release statistics at such “simple synapses” indicate that they contain a small complement of docking sites where vesicles repetitively dock and fuse. In this work, we investigate functional and morphological aspects of docking sites at simple synapses made between cerebellar parallel fibers and molecular layer interneurons. Using immunogold labeling of SDS-treated freeze-fracture replicas, we find that Cav2.1 channels form several clusters per active zone with about nine channels per cluster. The mean value and range of intersynaptic variation are similar for Cav2.1 cluster numbers and for functional estimates of docking-site numbers obtained from the maximum numbers of released vesicles per action potential. Both numbers grow in relation with synaptic size and decrease by a similar extent with age between 2 wk and 4 wk postnatal. Thus, the mean docking-site numbers were 3.15 at 2 wk (range: 1–10) and 2.03 at 4 wk (range: 1–4), whereas the mean numbers of Cav2.1 clusters were 2.84 at 2 wk (range: 1–8) and 2.37 at 4 wk (range: 1–5). These changes were accompanied by decreases of miniature current amplitude (from 93 pA to 56 pA), active-zone surface area (from 0.0427 μm2 to 0.0234 μm2), and initial success rate (from 0.609 to 0.353), indicating a tightening of synaptic transmission with development. Altogether, these results suggest a close correspondence between the number of functionally defined vesicular docking sites and that of clusters of voltage-gated calcium channels.

These various forms of plasticity might depend on the subsynaptic arrangement of the receptor in Purkinje cells that can be regulated by protein-protein interactions. This study investigated, by means of the freeze-fracture replica immunogold labelling method, the subcellular localization of mGlu1 receptors in the rodent cerebellum and whether Homer proteins regulate their subsynaptic distribution. We observed a widespread extrasynaptic localization of mGlu1 receptors and confirmed their peri-synaptic enrichment at glutamatergic synapses. Conversely, we detected mGlu1 receptors within the main body of GABAergic synapses onto Purkinje cell dendrites. Although Homer proteins are known to interact with the mGlu1 receptor C-terminus, we could not detect Homer3, the most abundant Homer protein in the cerebellar cortex, at GABAergic synapses by pre-embedding and post-embedding immunoelectron microscopy. We then hypothesized a critical role for Homer proteins in the peri-junctional localization of mGlu1 receptors at glutamatergic synapses. To disrupt Homer-associated protein complexes, mice were tail-vein injected with the membrane-permeable dominant-negative TAT-Homer1a. Freeze-fracture replica immunogold labelling analysis showed no significant alteration in the mGlu1 receptor distribution pattern at parallel fibre-Purkinje cell synapses, suggesting that other scaffolding proteins are involved in the peri-synaptic confinement. The identification of interactors that regulate the subsynaptic localization of the mGlu1 receptor at neurochemically distinct synapses may offer new insight into its trafficking and intracellular signalling.","lang":"eng"}],"date_updated":"2023-02-23T10:02:24Z","day":"01","month":"01","type":"journal_article","publication":"European Journal of Neuroscience","_id":"1515","tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","image":"/images/cc_by.png","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)"},"publisher":"Wiley-Blackwell","acknowledgement":"This work was supported by the Austrian Science Fund (FWF) (project W012060-10 to F.F.), The Japan Society for the Promotion of Science (JSPS) (to R.S.) and Agence Nationale de la Recherche (ANR-11-BSV4-018-03, DELTAPLAN), Région Languedoc-Roussillon (Chercheur d’Avenir) (to J.P.).
