CaV2.1, 2.2, and 2.3 are the major subunits of the voltage-gated calcium channel (VGCC) responsible for increasing intraterminal calcium levels and triggering SV exocytosis in the central nervous system (CNS) synapses. The two-dimensional analysis of CaV2 distributions using sodium dodecyl sulfate (SDS)-digested freeze-fracture replica labeling (SDS-FRL) has revealed their numbers, densities, and nanoscale clustering patterns in individual presynaptic active zones. The variation in these properties affects the coupling of VGCCs with calcium sensors on SVs, synaptic efficacy, and temporal precision of transmission. In this study, we summarize how the morphological parameters of CaV2 distribution obtained using SDS-FRL differ depending on the different types of synapses and could correspond to functional properties in synaptic transmission.","lang":"eng"}],"publication_status":"published","corr_author":"1","license":"https://creativecommons.org/licenses/by/4.0/","file":[{"date_updated":"2022-03-21T09:41:19Z","creator":"dernst","access_level":"open_access","content_type":"application/pdf","relation":"main_file","date_created":"2022-03-21T09:41:19Z","file_id":"10911","checksum":"51ec9b90e7da919e22c01a15489eaacd","success":1,"file_name":"2022_FrontiersNeuroanatomy_Eguchi.pdf","file_size":2416395}],"day":"24","oa":1,"language":[{"iso":"eng"}],"ec_funded":1,"oa_version":"Published Version","date_updated":"2026-04-16T08:18:54Z","department":[{"_id":"RySh"}],"article_processing_charge":"No","acknowledgement":"This work was supported by the European Research Council advanced grant No. 694539 and the joint German-Austrian DFG and FWF project SYNABS (FWF: I-4638-B) to RS.\r\nThe authors thank Walter Kaufmann for his critical comments on the manuscript.","date_created":"2022-03-20T23:01:39Z","publication_identifier":{"eissn":["1662-5129"]},"volume":16,"title":"The number and distinct clustering patterns of voltage-gated Calcium channels in nerve terminals","external_id":{"pmid":["35280978"],"isi":["000766662700001"]},"article_type":"original","publication":"Frontiers in Neuroanatomy","project":[{"call_identifier":"H2020","grant_number":"694539","_id":"25CA28EA-B435-11E9-9278-68D0E5697425","name":"In situ analysis of single channel subunit composition in neurons: physiological implication in synaptic plasticity and behaviour"},{"grant_number":"I04638","_id":"05970B30-7A3F-11EA-A408-12923DDC885E","name":"LGI1 antibody-induced pathophysiology in synapses"}],"year":"2022","isi":1,"type":"journal_article","intvolume":"        16","publisher":"Frontiers","file_date_updated":"2022-03-21T09:41:19Z","_id":"10890","author":[{"full_name":"Eguchi, Kohgaku","first_name":"Kohgaku","orcid":"0000-0002-6170-2546","id":"2B7846DC-F248-11E8-B48F-1D18A9856A87","last_name":"Eguchi"},{"last_name":"Montanaro-Punzengruber","id":"3786AB44-F248-11E8-B48F-1D18A9856A87","first_name":"Jacqueline-Claire","full_name":"Montanaro-Punzengruber, Jacqueline-Claire"},{"full_name":"Le Monnier, Elodie","last_name":"Le Monnier","id":"3B59276A-F248-11E8-B48F-1D18A9856A87","first_name":"Elodie"},{"full_name":"Shigemoto, Ryuichi","orcid":"0000-0001-8761-9444","id":"499F3ABC-F248-11E8-B48F-1D18A9856A87","last_name":"Shigemoto","first_name":"Ryuichi"}],"article_number":"846615","quality_controlled":"1","scopus_import":"1","has_accepted_license":"1","citation":{"ieee":"K.

The small-scale interactions of yarns colliding with and pulling on each\r\nother result in drastically different large-scale stretching and bending behavior, introducing\r\nanisotropy, curling, and more. While simulating cloth as individual yarns can reproduce this\r\ncomplexity and match the quality of real fabric, it may be too computationally expensive for\r\nlarge fabrics. On the other hand, continuum-based approaches do not need to discretize the\r\ncloth at a stitch-level, but it is non-trivial to find a material model that would replicate the\r\nlarge-scale behavior of yarn fabrics, and they discard the intricate visual detail. In this thesis,\r\nwe discuss three methods to try and bridge the gap between small-scale and large-scale yarn\r\nmechanics using numerical homogenization: fitting a continuum model to periodic yarn simulations, adding mechanics-aware yarn detail onto thin-shell simulations, and quantitatively\r\nfitting yarn parameters to physical measurements of real fabric.\r\nTo start, we present a method for animating yarn-level cloth effects using a thin-shell solver.\r\nWe first use a large number of periodic yarn-level simulations to build a model of the potential\r\nenergy density of the cloth, and then use it to compute forces in a thin-shell simulator. The\r\nresulting simulations faithfully reproduce expected effects like the stiffening of woven fabrics\r\nand the highly deformable nature and anisotropy of knitted fabrics at a fraction of the cost of\r\nfull yarn-level simulation.\r\nWhile our thin-shell simulations are able to capture large-scale yarn mechanics, they lack\r\nthe rich visual detail of yarn-level simulations. Therefore, we propose a method to animate\r\nyarn-level cloth geometry on top of an underlying deforming mesh in a mechanics-aware\r\nfashion in real time. Using triangle strains to interpolate precomputed yarn geometry, we are\r\nable to reproduce effects such as knit loops tightening under stretching at negligible cost.\r\nFinally, we introduce a methodology for inverse-modeling of yarn-level mechanics of cloth,\r\nbased on the mechanical response of fabrics in the real world. We compile a database from\r\nphysical tests of several knitted fabrics used in the textile industry spanning diverse physical\r\nproperties like stiffness, nonlinearity, and anisotropy. We then develop a system for approximating these mechanical responses with yarn-level cloth simulation, using homogenized\r\nshell models to speed up computation and adding some small-but-necessary extensions to\r\nyarn-level models used in computer graphics.\r\n","lang":"eng"}],"ddc":["000","620"],"doi":"10.15479/at:ista:12103","supervisor":[{"full_name":"Wojtan, Christopher J","first_name":"Christopher J","orcid":"0000-0001-6646-5546","id":"3C61F1D2-F248-11E8-B48F-1D18A9856A87","last_name":"Wojtan"}],"user_id":"ba8df636-2132-11f1-aed0-ed93e2281fdd","month":"09","oa":1,"language":[{"iso":"eng"}],"ec_funded":1,"oa_version":"Published Version","date_updated":"2026-04-16T08:31:54Z","alternative_title":["ISTA Thesis"],"corr_author":"1","file":[{"description":"This is the main PDF file of the thesis.

Information-flow properties are hyperproperties, as they compare different traces of a system. Sequential information-flow properties can express changes, over time, in the information-flow constraints. For example, information-flow constraints during an initialization phase of a system may be different from information-flow constraints that are required during the operation phase. We formalize several variants of interpreting sequential information-flow constraints, which arise from different assumptions about what can be observed of the system. For this purpose, we introduce a first-order logic, called Hypertrace Logic, with both trace and time quantifiers for specifying linear-time hyperproperties. We prove that HyperLTL, which corresponds to a fragment of Hypertrace Logic with restricted quantifier prefixes, cannot specify the majority of the studied variants of sequential information flow, including all variants in which the transition between sequential phases (such as initialization and operation) happens asynchronously. Our results rely on new equivalences between sets of traces that cannot be distinguished by certain classes of formulas from Hypertrace Logic. This presents a new approach to proving inexpressiveness results for HyperLTL.","lang":"eng"}],"publication_status":"published","status":"public","date_published":"2022-01-14T00:00:00Z","day":"14","arxiv":1,"alternative_title":["LNCS"],"oa_version":"Preprint","date_updated":"2026-04-16T09:13:43Z","oa":1,"language":[{"iso":"eng"}]},{"date_published":"2022-06-01T00:00:00Z","status":"public","publication_status":"published","abstract":[{"text":"A matching is compatible to two or more labeled point sets of size n with labels {1, . . . , n} if its straight-line drawing on each of these point sets is crossing-free.

Quantization is a technique that trades numerical precision for the computational efficiency of running a neural network and is widely adopted in industry.\r\nWe show that neglecting the reduced precision when verifying a neural network can lead to wrong conclusions about the robustness and safety of the network, highlighting that novel techniques for quantized network verification are necessary. We introduce several bit-exact verification methods explicitly designed for quantized neural networks and experimentally confirm on realistic networks that the network's robustness and other formal properties are affected by the quantization.\r\n\r\nFurthermore, we perform a case study providing evidence that adversarial training, a standard technique for making neural networks more robust, has detrimental effects on the network's performance. This robustness-accuracy tradeoff has been studied before regarding the accuracy obtained on classification datasets where each data point is independent of all other data points. On the other hand, we investigate the tradeoff empirically in robot learning settings where a both, a high accuracy and a high robustness, are desirable.\r\nOur results suggest that the negative side-effects of adversarial training outweigh its robustness benefits in practice.\r\n\r\nFinally, we consider the problem of verifying safety when running a Bayesian neural network policy in a feedback loop with systems over the infinite time horizon. Bayesian neural networks are probabilistic models for learning uncertainties in the data and are therefore often used on robotic and healthcare applications where data is inherently stochastic.\r\nWe introduce a method for recalibrating Bayesian neural networks so that they yield probability distributions over safe decisions only.\r\nOur method learns a safety certificate that guarantees safety over the infinite time horizon to determine which decisions are safe in every possible state of the system.\r\nWe demonstrate the effectiveness of our approach on a series of reinforcement learning benchmarks.","lang":"eng"}],"publication_status":"published","ddc":["004"],"doi":"10.15479/at:ista:11362","supervisor":[{"first_name":"Thomas A","id":"40876CD8-F248-11E8-B48F-1D18A9856A87","last_name":"Henzinger","orcid":"0000-0002-2985-7724","full_name":"Henzinger, Thomas A"}],"user_id":"ba8df636-2132-11f1-aed0-ed93e2281fdd","tmp":{"legal_code_url":"https://creativecommons.org/licenses/by-nd/4.0/legalcode","name":"Creative Commons Attribution-NoDerivatives 4.0 International (CC BY-ND 4.0)","image":"/image/cc_by_nd.png","short":"CC BY-ND (4.0)"},"month":"05","author":[{"last_name":"Lechner","id":"3DC22916-F248-11E8-B48F-1D18A9856A87","first_name":"Mathias","full_name":"Lechner, Mathias"}],"_id":"11362","file_date_updated":"2022-05-17T15:19:39Z","citation":{"ama":"Lechner M.

In this work, we take a mean-field view, and consider a two-layer ReLU network trained via noisy-SGD for a univariate regularized regression problem. Our main result is that SGD with vanishingly small noise injected in the gradients is biased towards a simple solution: at convergence, the ReLU network implements a piecewise linear map of the inputs, and the number of “knot” points -- i.e., points where the tangent of the ReLU network estimator changes -- between two consecutive training inputs is at most three. In particular, as the number of neurons of the network grows, the SGD dynamics is captured by the solution of a gradient flow and, at convergence, the distribution of the weights approaches the unique minimizer of a related free energy, which has a Gibbs form. Our key technical contribution consists in the analysis of the estimator resulting from this minimizer: we show that its second derivative vanishes everywhere, except at some specific locations which represent the “knot” points. We also provide empirical evidence that knots at locations distinct from the data points might occur, as predicted by our theory.","lang":"eng"}],"publication_status":"published","ddc":["000"],"file":[{"success":1,"file_size":1521701,"file_name":"21-1365.pdf","date_created":"2022-05-30T08:22:55Z","file_id":"11422","checksum":"d4ff5d1affb34848b5c5e4002483fc62","content_type":"application/pdf","relation":"main_file","date_updated":"2022-05-30T08:22:55Z","creator":"cchlebak","access_level":"open_access"}],"corr_author":"1","day":"01","language":[{"iso":"eng"}],"oa":1,"arxiv":1,"issue":"130","oa_version":"Published Version","date_updated":"2026-05-02T22:30:05Z"},{"isi":1,"type":"journal_article","intvolume":"       221","publisher":"Rockefeller University Press","file_date_updated":"2023-02-21T23:30:39Z","_id":"12080","author":[{"last_name":"Enshoji","first_name":"Mariko","full_name":"Enshoji, Mariko"},{"full_name":"Miyano, Yoshiko","first_name":"Yoshiko","last_name":"Miyano"},{"last_name":"Yoshida","first_name":"Nao","full_name":"Yoshida, Nao"},{"last_name":"Nagano","first_name":"Makoto","full_name":"Nagano, Makoto"},{"full_name":"Watanabe, Minami","first_name":"Minami","last_name":"Watanabe"},{"first_name":"Mayumi","last_name":"Kunihiro","full_name":"Kunihiro, Mayumi"},{"orcid":"0000-0001-8323-8353","id":"3D224B9E-F248-11E8-B48F-1D18A9856A87","last_name":"Siekhaus","first_name":"Daria E","full_name":"Siekhaus, Daria E"},{"first_name":"Junko Y.","last_name":"Toshima","full_name":"Toshima, Junko Y."},{"full_name":"Toshima, Jiro","last_name":"Toshima","first_name":"Jiro"}],"scopus_import":"1","article_number":"e202112138","quality_controlled":"1","has_accepted_license":"1","citation":{"ista":"Enshoji M, Miyano Y, Yoshida N, Nagano M, Watanabe M, Kunihiro M, Siekhaus DE, Toshima JY, Toshima J. 2022.

This process can be divided into two phases: an early phase, in which sites of endocytosis are formed, and a late phase in which clathrin-coated vesicles are formed and internalized into the cytosol, but how these phases link to each other remains unclear. In this study, we demonstrate that anchoring the yeast Eps15-like protein Pan1p to the peroxisome triggers most of the events occurring during the late phase at the peroxisome. At this ectopic location, Pan1p recruits most proteins that function in the late phases—including actin nucleation promoting factors—and then initiates actin polymerization. Pan1p also recruited Prk1 kinase and actin depolymerizing factors, thereby triggering disassembly immediately after actin assembly and inducing dissociation of endocytic proteins from the peroxisome. These observations suggest that Pan1p is a key regulator for initiating, processing, and completing the late phase of endocytosis."}]},{"doi":"10.15479/AT:ISTA:11653","department":[{"_id":"GradSch"},{"_id":"BeVi"}],"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","date_created":"2022-07-26T11:01:47Z","tmp":{"short":"CC BY (4.0)","image":"/images/cc_by.png","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode"},"article_processing_charge":"No","month":"08","contributor":[{"first_name":"Marwan N","orcid":"0000-0002-5328-7231","id":"0B46FACA-A8E1-11E9-9BD3-79D1E5697425","last_name":"Elkrewi"},{"first_name":"Uladzislava","last_name":"Khauratovich"},{"first_name":"Melissa A","last_name":"Toups","id":"4E099E4E-F248-11E8-B48F-1D18A9856A87"},{"first_name":"Vincent K","id":"57854184-AAE0-11E9-8D04-98D6E5697425","last_name":"Bett"},{"last_name":"Mrnjavac","id":"353FAC84-AE61-11E9-8BFC-00D3E5697425","first_name":"Andrea"},{"first_name":"Ariana","id":"2A0848E2-F248-11E8-B48F-1D18A9856A87","last_name":"Macon"},{"first_name":"Christelle","id":"32DF5794-F248-11E8-B48F-1D18A9856A87","last_name":"Fraisse","orcid":"0000-0001-8441-5075"},{"last_name":"Sax","first_name":"Luca"},{"id":"4C0A3874-F248-11E8-B48F-1D18A9856A87","last_name":"Huylmans","first_name":"Ann K"},{"last_name":"Hontoria ","first_name":"Francisco"},{"orcid":"0000-0002-4579-8306","last_name":"Vicoso","id":"49E1C5C6-F248-11E8-B48F-1D18A9856A87","first_name":"Beatriz"}],"title":"Data from Elkrewi, Khauratovich, Toups et al. 2022, \"ZW sex-chromosome evolution and contagious parthenogenesis in Artemia brine shrimp\"","date_published":"2022-08-05T00:00:00Z","status":"public","year":"2022","abstract":[{"text":"Eurasian brine shrimp (genus Artemia) have closely related sexual and asexual lineages of parthenogenetic females, which produce rare males at low frequencies. Although they are known to have ZW chromosomes, these are not well characterized, and it is unclear whether they are shared across the clade. Furthermore, the underlying genetic architecture of the transmission of asexuality, which can occur when rare males mate with closely related sexual females, is not well understood. We produced a chromosome-level assembly for the sexual Eurasian species A. sinica and characterized in detail the pair of sex chromosomes of this species. We combined this new assembly with short-read genomic data for the sexual species A. sp. Kazakhstan and several asexual lineages of A. parthenogenetica, allowing us to perform an in-depth characterization of sex-chromosome evolution across the genus. We identified a small differentiated region of the ZW pair that is shared by all sexual and asexual lineages, supporting the shared ancestry of the sex chromosomes. We also inferred that recombination suppression has spread to larger sections of the chromosome independently in the American and Eurasian lineages. Finally, we took advantage of a rare male, which we backcrossed to sexual females, to explore the genetic basis of asexuality. Our results suggest that parthenogenesis is likely partly controlled by a locus on the Z chromosome, highlighting the interplay between sex determination and asexuality.","lang":"eng"}],"ddc":["570"],"related_material":{"record":[{"status":"public","id":"12248","relation":"used_in_publication"}]},"corr_author":"1","type":"research_data","file":[{"title":"Supplementary Datasets","content_type":"application/x-zip-compressed","relation":"main_file","creator":"melkrewi","access_level":"open_access","description":"The folder contains the following datasets (fasta files, and text files):\nSup.

The study of the relations between these datasets and their sequence similarity analysis is of interest to many applications such as health monitoring and recommender systems. However, entering all movement parameters and health signals can lead to the complexity of the problem and an increase in its computational load. In this situation, dimension reduction techniques can be used to avoid consideration of simultaneous dependent parameters in the process of similarity measurement of the trajectories. The present study provides a framework, named CaDRAW, to use spatial–temporal data and movement parameters along with independent context information in the process of measuring the similarity of trajectories. In this regard, the omission of dependent movement characteristic signals is conducted by using an unsupervised feature selection dimension reduction technique. To evaluate the effectiveness of the proposed framework, it was applied to a real contextualized movement and related health signal datasets of individuals. The results indicated the capability of the proposed framework in measuring the similarity and in decreasing the characteristic signals in such a way that the similarity results -before and after reduction of dependent characteristic signals- have small differences. The mean differences between the obtained results before and after reducing the dimension were 0.029 and 0.023 for the round path, respectively.","lang":"eng"}],"ddc":["000"],"status":"public","date_published":"2022-05-01T00:00:00Z","publisher":"Springer Nature","intvolume":"        13","type":"journal_article","isi":1,"citation":{"ama":"Goudarzi S, Sharif M, Karimipour F.

The quantum hardware is used to implement a variational wave function and measure observables, whereas the classical computer is used to store and update the variational parameters. The optimization landscape of expressive variational ansätze is however dominated by large regions in parameter space, known as barren plateaus, with vanishing gradients, which prevents efficient optimization. In this work we propose a general algorithm to avoid barren plateaus in the initialization and throughout the optimization. To this end we define a notion of weak barren plateaus (WBPs) based on the entropies of local reduced density matrices. The presence of WBPs can be efficiently quantified using recently introduced shadow tomography of the quantum state with a classical computer. We demonstrate that avoidance of WBPs suffices to ensure sizable gradients in the initialization. In addition, we demonstrate that decreasing the gradient step size, guided by the entropies allows WBPs to be avoided during the optimization process.

FtsA allegedly initiates cell division by switching from an inactive polymeric to an active monomeric confirmation, which recruits downstream proteins and stabilizes FtsZ filaments. Here, we use biochemical reconstitution experiments combined with quantitative fluorescence microscopy to study divisome activation in vitro. We compare wildtype-FtsA with FtsA-R286W, a constantly active gain-of-function mutant and find that R286W outperforms the wildtype protein in replicating FtsZ treadmilling dynamics, stabilizing FtsZ filaments and recruiting FtsN. We attribute these differences to a faster membrane exchange of FtsA-R286W and its higher packing density below FtsZ filaments.  Using FRET microscopy, we find that FtsN binding does not compete with, but promotes FtsA self-interaction. Our findings suggest a model where FtsA always forms dynamic polymers on the membrane, which re-organize during assembly and activation of the divisome.

essential for E. coli cell division, as it links FtsZ filaments in the Z-ring to transmembrane proteins. FtsA is thought to initiate cell constriction by switching from an inactive polymeric to an active monomeric conformation, which recruits downstream proteins and stabilizes the Z-ring. However, direct biochemical evidence for this mechanism is missing. Here, we use reconstitution experiments and quantitative fluorescence microscopy to study divisome activation in vitro. By comparing wild-type FtsA with FtsA R286W, we find that this hyperactive mutant outperforms FtsA WT in replicating FtsZ treadmilling dynamics, FtsZ filament stabilization and recruitment of FtsN. We could attribute these differences to a faster exchange and denser packing of FtsA R286W below FtsZ filaments. Using FRET microscopy, we also find that FtsN binding promotes FtsA self-interaction. We propose that in the active divisome FtsA and FtsN exist as a dynamic copolymer that follows treadmilling filaments of FtsZ.","lang":"eng"}],"publication_status":"published","corr_author":"1","file":[{"checksum":"5af863ee1b95a0710f6ee864d68dc7a6","date_created":"2022-05-13T09:10:51Z","file_id":"11374","success":1,"file_size":6945191,"file_name":"2022_NatureCommunications_Radler.pdf","creator":"dernst","access_level":"open_access","date_updated":"2022-05-13T09:10:51Z","content_type":"application/pdf","relation":"main_file"}],"day":"12","ec_funded":1,"language":[{"iso":"eng"}],"oa":1,"date_updated":"2026-05-02T22:30:29Z","oa_version":"Published Version","department":[{"_id":"MaLo"}],"article_processing_charge":"No","acknowledgement":"We acknowledge members of the Loose laboratory at IST Austria for helpful discussions—in particular L.

While synaptic transmission remains a dynamic process, electron microscopy provides images with comparably low temporal resolution (Studer et al., 2014). The current work overcomes this challenge and describes an improved “Flash and Freeze” technique (Watanabe et al., 2013a; Watanabe et al., 2013b) to study synaptic transmission at the hippocampal mossy fiber-CA3 pyramidal neuron synapses, using mouse acute brain slices and organotypic slices culture. The improved method allowed for selective stimulation of presynaptic mossy fiber boutons and the observation of synaptic vesicle pool dynamics at the active zones. Our results uncovered several intriguing morphological features of mossy fiber boutons. First, the docked vesicle pool was largely depleted (more than 70%) after stimulation, implying that the docked synaptic vesicles pool and readily releasable pool are vastly overlapping in mossy fiber boutons. Second, the synaptic vesicles are skewed towards larger diameters, displaying a wide range of sizes. An increase in the mean diameter of synaptic vesicles, after single and repetitive stimulation, suggests that smaller vesicles have a higher release probability. Third, we observed putative endocytotic structures after moderate light stimulation, matching the timing of previously described ultrafast endocytosis (Watanabe et al., 2013a; Delvendahl et al., 2016). \r\n\tIn addition, synaptic transmission depends on a sophisticated system of protein machinery and calcium channels (Südhof, 2013b), which amplifies the challenge in studying synaptic communication as these interactions can be potentially modified during synaptic plasticity. And although recent study elucidated the potential correlation between physiological and morphological properties of synapses during synaptic plasticity (Vandael et al., 2020), the molecular underpinning of it remains unknown. Thus, the presented work tries to overcome this challenge and aims to pinpoint changes in the molecular architecture at hippocampal mossy fiber bouton synapses during short- and long-term potentiation (STP and LTP), we combined chemical potentiation, with the application of a cyclic adenosine monophosphate agonist (i.e. forskolin) and freeze-fracture replica immunolabelling. This method allowed the localization of membrane-bound proteins with nanometer precision within the active zone, in particular, P/Q-type calcium channels and synaptic vesicle priming proteins Munc13-1/2. First, we found that the number of clusters of Munc13-1 in the mossy fiber bouton active zone increased significantly during STP, but decreased to lower than the control value during LTP. Secondly, although the distance between the calcium channels and Munc13-1s did not change after induction of STP, it shortened during the LTP phase. Additionally, forskolin did not affect Munc13-2 distribution during STP and LTP. These results indicate the existence of two distinct mechanisms that govern STP and LTP at mossy fiber bouton synapses: an increase in the readily realizable pool in the case of STP and a potential increase in release probability during LTP. “Flash and freeze” and functional electron microscopy, are versatile methods that can be successfully applied to intact brain circuits to study synaptic transmission even at the molecular level.\r\n"}],"ddc":["570"],"doi":"10.15479/at:ista:11196","supervisor":[{"full_name":"Jonas, Peter M","last_name":"Jonas","id":"353C1B58-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0001-5001-4804","first_name":"Peter M"}],"user_id":"ba8df636-2132-11f1-aed0-ed93e2281fdd","tmp":{"name":"Creative Commons Attribution-NonCommercial-NoDerivatives 4.0 International (CC BY-NC-ND 4.0)","legal_code_url":"https://creativecommons.org/licenses/by-nc-nd/4.0/legalcode","short":"CC BY-NC-ND (4.0)","image":"/images/cc_by_nc_nd.png"},"month":"04","author":[{"full_name":"Kim, Olena","first_name":"Olena","orcid":"0000-0003-2344-1039","last_name":"Kim","id":"3F8ABDDA-F248-11E8-B48F-1D18A9856A87"}],"file_date_updated":"2023-04-20T22:30:03Z","_id":"11196","citation":{"mla":"Kim, Olena. <i>Nanoarchitecture of Hippocampal Mossy Fiber-CA3 Pyramidal Neuron Synapses</i>.

Even though pathogens should thrive in social insect colonies as the hosts engage in frequent social interactions, are closely related and live in a pathogen-rich environment, disease outbreaks are rare. This is because social insects have evolved mechanisms to keep pathogens at bay – and fight disease as a collective. Social insect colonies are often viewed as “superorganisms” with division of labor between reproductive “germ-like” queens and males and “somatic” workers, which together form an interdependent reproductive unit that parallels a multicellular body. Superorganisms possess a “social immune system” that comprises of collective disease defenses performed by the workers - summarized as “social immunity”. In social groups immunization (reduced susceptibility to a parasite upon secondary exposure to the same parasite) can e.g. be triggered by social interactions (“social immunization”). Social immunization can be caused by (i) asymptomatic low-level infections that are acquired during caregiving to a contagious individual that can give an immune boost, which can induce protection upon later encounter with the same pathogen (active immunization) or (ii) by transfer of immune effectors between individuals (passive immunization).\r\nIn the second chapter, I built up on a study that I co-authored that found that low-level infections can not only be protective, but also be costly and make the host more susceptible to detrimental superinfections after contact to a very dissimilar pathogen. I here now tested different degrees of phylogenetically-distant fungal strains of M. brunneum and M. robertsii in L. neglectus and can describe the occurrence of cross-protection of social immunization if the first and second pathogen are from the same level. Interestingly, low-level infections only provided protection when the first strain was less virulent than the second strain and elicited higher immune gene expression.\r\nIn the third and fourth chapters, I expanded on the role of social immunity in sexual selection, a so far unstudied field. I used the fungus Metarhizium robertsii and the ant Cardiocondyla obscurior as a model, as in this species mating occurs in the presence of workers and can be studied under laboratory conditions. Before males mate with virgin queens in the nest they engage in fierce combat over the access to their mating partners.\r\nFirst, I focused on male-male competition in the third chapter and found that fighting with a contagious male is costly as it can lead to contamination of the rival, but that workers can decrease the risk of disease contraction by performing sanitary care.\r\nIn the fourth chapter, I studied the effect of fungal infection on survival and mating success of sexuals (freshly emerged queens and males) and found that worker-performed sanitary care can buffer the negative effect that a pathogenic contagion would have on sexuals by spore removal from the exposed individuals. When social immunity was prevented and queens could contract spores from their mating partner, very low dosages led to negative consequences: their lifespan was reduced and they produced fewer offspring with poor immunocompetence compared to healthy queens. Interestingly, cohabitation with a late-stage infected male where no spore transfer was possible had a positive effect on offspring immunity – male offspring of mothers that apparently perceived an infected partner in their vicinity reacted more sensitively to fungal challenge than male offspring without paternal pathogen history.","lang":"eng"}],"ddc":["570"],"date_published":"2022-02-07T00:00:00Z","status":"public","month":"02","doi":"10.15479/AT:ISTA:10727","supervisor":[{"first_name":"Sylvia","last_name":"Cremer","id":"2F64EC8C-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-2193-3868","full_name":"Cremer, Sylvia"}],"user_id":"ba8df636-2132-11f1-aed0-ed93e2281fdd","alternative_title":["ISTA Thesis"],"oa_version":"Published Version","date_updated":"2026-04-07T14:30:18Z","ec_funded":1,"language":[{"iso":"eng"}],"oa":1,"day":"07","corr_author":"1","file":[{"checksum":"47ba18bb270dd6cc266e0a3f7c69d0e4","date_created":"2022-02-04T15:36:12Z","file_id":"10728","file_size":6757886,"file_name":"Thesis_Sina_Metzler.docx","creator":"smetzler","access_level":"closed","date_updated":"2023-02-03T23:30:03Z","content_type":"application/vnd.openxmlformats-officedocument.wordprocessingml.document","embargo_to":"open_access","relation":"source_file"},{"content_type":"application/pdf","relation":"main_file","embargo":"2023-02-02","date_updated":"2023-02-03T23:30:03Z","creator":"smetzler","access_level":"open_access","file_name":"Thesis_Sina_Metzler_A2.pdf","file_size":6314921,"date_created":"2022-02-04T15:36:43Z","file_id":"10730","checksum":"f3ec07d5d6b20ae6e46bfeedebce9027"},{"file_name":"Thesis_Sina_Metzler_print.pdf","file_size":6882557,"checksum":"dedd14b7be7a75d63018dbfc68dd8113","date_created":"2022-02-07T10:35:02Z","file_id":"10742","content_type":"application/pdf","relation":"main_file","creator":"smetzler","access_level":"open_access","embargo":"2023-02-02","date_updated":"2023-02-04T23:30:03Z"}]},{"author":[{"full_name":"Artner, Christina","id":"45DF286A-F248-11E8-B48F-1D18A9856A87","last_name":"Artner","first_name":"Christina"}],"file_date_updated":"2023-09-09T22:30:03Z","_id":"11879","citation":{"chicago":"Artner, Christina. “Modulation of Auxin Transport via ZF Proteins Adjust Plant Response to High Ambient Temperature.” Institute of Science and Technology Austria, 2022. <a href=\"https://doi.org/10.15479/at:ista:11879\">https://doi.org/10.15479/at:ista:11879</a>.","apa":"Artner, C.

Plants are\r\nsessile organisms, thus to compensate for their lack of mobility, they evolved a variety of\r\nmechanisms enabling them to flexibly adjust their physiological, growth and developmental\r\nprocesses to fluctuating temperatures and to survive in harsh environments. While these unique\r\nadaptation abilities provide an important evolutionary advantage, overall modulation of plant\r\ngrowth and developmental program due to non-optimal temperature negatively affects biomass\r\nproduction, crop productivity or sensitivity to pathogens. Thus, understanding molecular\r\nprocesses underlying plant adaptation to increased temperature can provide important\r\nresources for breeding strategies to ensure sufficient agricultural food production.\r\nAn increase in ambient temperature by a few degrees leads to profound changes in organ growth\r\nincluding enhanced hypocotyl elongation, expansion of petioles, hyponastic growth of leaves and\r\ncotyledons, collectively named thermomorphogenesis (Casal & Balasubramanian, 2019). Auxin,\r\none of the best-studied growth hormones, plays an essential role in this process by direct\r\nactivation of transcriptional and non-transcriptional processes resulting in elongation growth\r\n(Majda & Robert, 2018).To modulate hypocotyl growth in response to high ambient temperature\r\n(hAT), auxin needs to be redistributed accordingly. PINs, auxin efflux transporters, are key\r\ncomponents of the polar auxin transport (PAT) machinery, which controls the amount and\r\ndirection of auxin translocated in the plant tissues and organs(Adamowski & Friml, 2015). Hence,\r\nPIN-mediated transport is tightly linked with thermo-morphogenesis, and interference with PAT\r\nthrough either chemical or genetic means dramatically affecting the adaptive responses to hAT.\r\nIntriguingly, despite the key role of PIN mediated transport in growth response to hAT, whether\r\nand how PINs at the level of expression adapt to fluctuation in temperature is scarcely\r\nunderstood.\r\nWith genetic, molecular and advanced bio-imaging approaches, we demonstrate the role of PIN\r\nauxin transporters in the regulation of hypocotyl growth in response to hAT. We show that via\r\nadjustment of PIN3, PIN4 and PIN7 expression in cotyledons and hypocotyls, auxin distribution is modulated thereby determining elongation pattern of epidermal cells at hAT. Furthermore, we\r\nidentified three Zinc-Finger (ZF) transcription factors as novel molecular components of the\r\nthermo-regulatory network, which through negative regulation of PIN transcription adjust the\r\ntransport of auxin at hAT. Our results suggest that the ZF-PIN module might be a part of the\r\nnegative feedback loop attenuating the activity of the thermo-sensing pathway to restrain\r\nexaggerated growth and developmental responses to hAT.","lang":"eng"}],"publication_status":"published","ddc":["580"],"supervisor":[{"orcid":"0000-0002-8510-9739","id":"38F4F166-F248-11E8-B48F-1D18A9856A87","last_name":"Benková","first_name":"Eva","full_name":"Benková, Eva"}],"doi":"10.15479/at:ista:11879","user_id":"ba8df636-2132-11f1-aed0-ed93e2281fdd","month":"08"},{"date_updated":"2026-05-02T22:30:32Z","oa_version":"Submitted Version","issue":"7928","language":[{"iso":"eng"}],"ec_funded":1,"oa":1,"day":"22","file":[{"relation":"main_file","content_type":"application/pdf","date_updated":"2023-05-30T17:05:31Z","access_level":"open_access","creator":"lsazanov","file_name":"EcCxI_manuscript_rev3_noSI_updated_withFigs_opt.pdf","file_size":1425655,"success":1,"file_id":"13104","date_created":"2023-05-30T17:05:31Z","checksum":"d42a93e24f59e883ef0b5429832391d0"},{"checksum":"5422bc0a73b3daadafa262c7ea6deae3","date_created":"2023-05-30T17:07:05Z","file_id":"13105","success":1,"file_name":"EcCxI_manuscript_rev3_SI_All_opt_upd.pdf","file_size":9842513,"creator":"lsazanov","access_level":"open_access","date_updated":"2023-05-30T17:07:05Z","content_type":"application/pdf","relation":"main_file"}],"corr_author":"1","ddc":["572"],"publication_status":"published","abstract":[{"lang":"eng","text":"Complex I is the first enzyme in the respiratory chain, which is responsible for energy production in mitochondria and bacteria1. Complex I couples the transfer of two electrons from NADH to quinone and the translocation of four protons across the membrane2, but the coupling mechanism remains contentious. Here we present cryo-electron microscopy structures of Escherichia coli complex I (EcCI) in different redox states, including catalytic turnover. EcCI exists mostly in the open state, in which the quinone cavity is exposed to the cytosol, allowing access for water molecules, which enable quinone movements. Unlike the mammalian paralogues3, EcCI can convert to the closed state only during turnover, showing that closed and open states are genuine turnover intermediates. The open-to-closed transition results in the tightly engulfed quinone cavity being connected to the central axis of the membrane arm, a source of substrate protons. Consistently, the proportion of the closed state increases with increasing pH. We propose a detailed but straightforward and robust mechanism comprising a ‘domino effect’ series of proton transfers and electrostatic interactions: the forward wave (‘dominoes stacking’) primes the pump, and the reverse wave (‘dominoes falling’) results in the ejection of all pumped protons from the distal subunit NuoL. This mechanism explains why protons exit exclusively from the NuoL subunit and is supported by our mutagenesis data. We contend that this is a universal coupling mechanism of complex I and related enzymes."}],"status":"public","date_published":"2022-09-22T00:00:00Z","month":"09","user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","doi":"10.1038/s41586-022-05199-7","pmid":1,"keyword":["Multidisciplinary"],"citation":{"chicago":"Kravchuk, Vladyslav, Olga Petrova, Domen Kampjut, Anna Wojciechowska-Bason, Zara Breese, and Leonid A Sazanov. “A Universal Coupling Mechanism of Respiratory Complex I.” <i>Nature</i>.

While its phenotypic spectrum often encompasses macrocephaly, implicating cortical abnormalities, how CHD8 haploinsufficiency affects neurodevelopmental is unclear. Here, employing human cerebral organoids, we find that CHD8 haploinsufficiency disrupted neurodevelopmental trajectories with an accelerated and delayed generation of, respectively, inhibitory and excitatory neurons that yields, at days 60 and 120, symmetrically opposite expansions in their proportions. This imbalance is consistent with an enlargement of cerebral organoids as an in vitro correlate of patients’ macrocephaly. Through an isogenic design of patient-specific mutations and mosaic organoids, we define genotype-phenotype relationships and uncover their cell-autonomous nature. Our results define cell-type-specific CHD8-dependent molecular defects related to an abnormal program of proliferation and alternative splicing. By identifying cell-type-specific effects of CHD8 mutations, our study uncovers reproducible developmental alterations that may be employed for neurodevelopmental disease modeling.","lang":"eng"}],"isi":1,"type":"journal_article","publisher":"Elsevier","intvolume":"        39","_id":"11160","file_date_updated":"2022-04-15T09:06:25Z","author":[{"full_name":"Villa, Carlo Emanuele","first_name":"Carlo Emanuele","last_name":"Villa"},{"first_name":"Cristina","last_name":"Cheroni","full_name":"Cheroni, Cristina"},{"first_name":"Christoph","orcid":"0000-0002-9033-9096","id":"4C66542E-F248-11E8-B48F-1D18A9856A87","last_name":"Dotter","full_name":"Dotter, Christoph"},{"last_name":"López-Tóbon","first_name":"Alejandro","full_name":"López-Tóbon, Alejandro"},{"id":"3B03AA1A-F248-11E8-B48F-1D18A9856A87","last_name":"Oliveira","first_name":"Bárbara","full_name":"Oliveira, Bárbara"},{"last_name":"Sacco","id":"42C9F57E-F248-11E8-B48F-1D18A9856A87","first_name":"Roberto","full_name":"Sacco, Roberto"},{"full_name":"Yahya, Aysan Çerağ","last_name":"Yahya","id":"365A65F8-F248-11E8-B48F-1D18A9856A87","first_name":"Aysan Çerağ"},{"first_name":"Jasmin","id":"4739D480-F248-11E8-B48F-1D18A9856A87","last_name":"Morandell","full_name":"Morandell, Jasmin"},{"full_name":"Gabriele, Michele","first_name":"Michele","last_name":"Gabriele"},{"full_name":"Tavakoli, Mojtaba","orcid":"0000-0002-7667-6854","id":"3A0A06F4-F248-11E8-B48F-1D18A9856A87","last_name":"Tavakoli","first_name":"Mojtaba"},{"full_name":"Lyudchik, Julia","first_name":"Julia","id":"46E28B80-F248-11E8-B48F-1D18A9856A87","last_name":"Lyudchik"},{"first_name":"Christoph M","id":"4DF26D8C-F248-11E8-B48F-1D18A9856A87","last_name":"Sommer","orcid":"0000-0003-1216-9105","full_name":"Sommer, Christoph M"},{"first_name":"Mariano","last_name":"Gabitto","full_name":"Gabitto, Mariano"},{"full_name":"Danzl, Johann G","first_name":"Johann G","last_name":"Danzl","id":"42EFD3B6-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0001-8559-3973"},{"full_name":"Testa, Giuseppe","first_name":"Giuseppe","last_name":"Testa"},{"id":"3E57A680-F248-11E8-B48F-1D18A9856A87","last_name":"Novarino","orcid":"0000-0002-7673-7178","first_name":"Gaia","full_name":"Novarino, Gaia"}],"keyword":["General Biochemistry","Genetics and Molecular Biology"],"citation":{"ama":"Villa CE, Cheroni C, Dotter C, et al.
