A quantitative analysis of the molecular organization of dendritic spines from hippocampal neurons
(2019-08-20)Dendritic spines are the major excitatory postsynaptic compartment in the brain. Despite its essential function in synaptic transmission and plasticity, we are still lacking a comprehensive and quantitative understanding ... -
Active and Passive Microrheology of F-Actin Membrane Composites
(2018-07-19)The complex mechanical properties of a living cell are not only a function of its structural components but also of the organizational super-structure and the dynamic interconnection of filaments, proteins and the plasma ... -
Brain-wide connectivity of molecularly defined GABAergic neurons in mouse barrel cortex visualized with optimized rabies virus tracing
(2020-03-16)Cortical GABAergic neurons are indispensable in controlling the activity of cortical networks. Parvalbu- min (PV), somatostatin (SST) and vasoactive intestinal polypeptide (VIP) expressing neurons are three main classes ... -
Characterizing intracellular lipid signaling in dilated cardiomyopathy using human iPSC-derived cardiac cells
(2023-04-18)Sarcomere protein misalignment is a primary consequence of inherited mutations causing dilated cardiomyopathy (DCM) and results in severe molecular patho-phenotypes in cardiomyocytes from patients. In this study, human ... -
Design strategies for carbon nanotube-based biosensors
(2020-07-09)Global health crises such as the COVID-19 pandemic clearly show the need for novel and better diagnostic and therapeutic tools. Additionally, understanding underlying molecular processes is crucial. However, current methods ... -
Development of a versatile microfluidic platform to study the ionic mechanisms of vesicular neurotransmitter transporters
(2021-11-04)This thesis described the development of a novel, versatile microfluidic platform for studying the ionic mechanisms of vesicular neurotransmitter transporters in rodent synaptic vesicles (SVs). The level of filling of an ... -
Development of Nanobodies to Image Synaptic Proteins in Super-Resolution Microscopy
(2018-10-17)In the recent decades, super resolution microscopy substantially contributed to the investigation of subcellular structures. A prominent example is the molecular organization of the synapse which is known to be vital for ... -
Dynamics and self-organization of membrane-bound minimal actin and actomyosin cortices based on ezrin-PtdIns[4,5]P2 linkage
(2022-11-22)The cellular cortex is a thin actin layer attached to the cytoplasmatic plasma membrane leaflet of mammalian cells. Through a complex interaction with hundreds of actin binding proteins (ABPs), controlling e.g. the cortex ... -
Investigating post-translational modifications and novel interaction partners of otoferlin
(2019-10-30)Otoferlin is a large multi-C2-domain protein essential for hearing and fast Ca2+-triggered transmitter release from auditory IHCs. Mutations in the OTOF gene are linked to a form of autosomal recessive non-syndromic hearing ... -
Mechanics and Motility of Epithelial Cells: From Single Cell Behavior to Collective Migration
(2023-01-13)Mechanical behavior of cells plays a crucial role in a plethora of biological processes. Despite its importance, this aspect of life science has only more recently gained increasing interest. Yet, without mechanical force ... -
Mechanisms of synaptic plasticity mediated by Clathrin Adaptor-protein complexes 1 and 2 in mice
(2019-06-13)Clathrin adaptor protein complexes 1 and 2 (AP1 and AP2) have essential functions in synaptic vesicle (SV) recycling. In all cell types and tissues, AP1 mediates TGN/endosome protein sorting via clathrin-coated-vesicles ... -
Microfluidic cryofixation for time-correlated live-imaging cryo-fluorescence microscopy and electron microscopy of Caenorhabditis elegans
(2018-11-01)Light and electron microscopy are complementary methods to study biological systems at the cellular and sub-cellular scale. Light microscopy is compatible with live cells, allowing features of interest to be selectively ... -
Mitochondrial adaptation at the neuronal presynapse
(2021-11-22)Synaptic transmission poses a major energy consuming process in the brain, but how neurons maintain a constant energy supply during extended synaptic activity and how presynaptic mitochondria contribute to the energy ... -
Modifications in AP2 and clathrin-mediated endocytosis as a mechanism of synaptic plasticity
(2022-07-01)AP2 CME fulfills essential functions in embryonic development and cell survival. The AP2 complex and clathrin form AP2 CCV together with sixty other coat proteins. Due to this complex protein network, the regulation of CCV ... -
