Munc18-1 is a dynamically regulated PKC target during short-term enhancement of transmitter release

Ralf Schneggenburger, Olexiy Kochubey, Özgür Genç

Transmitter release at synapses is regulated by preceding neuronal activity, which can give rise to short-term enhancement of release like post-tetanic potentiation (PTP). Diacylglycerol (DAG) and Protein-kinase C (PKC) signaling in the nerve terminal have ...

Role of Protein Kinase C and Munc18-1 in a Presynaptic Form of Plasticity, Post-tetanic Potentiation

Özgür Genç

Neurons are arranged in networks in which they communicate between each other by the means of synapses. Synaptic transmission can undergo activity-dependent and short-lived changes in strength, known as short-term synaptic plasticity. Short-term plasticity ...

Ca2+ channels and transmitter release at the active zone

Ralf Schneggenburger, Olexiy Kochubey, Yunyun Han

Ca2+-dependent transmitter release is the most important signaling mechanism for fast information transfer between neurons. Transmitter release takes places at highly specialized active zones with sub-micrometer dimension, which contain the molecular machi ...

Predicting Novel Binding Modes of Agonists to β Adrenergic Receptors Using All-Atom Molecular Dynamics Simulations

Ursula Röthlisberger, Ivano Tavernelli, Marilisa Neri, Stefano Vanni

Understanding the binding mode of agonists to adrenergic receptors is crucial to enabling improved rational design of new therapeutic agents. However, so far the high conformational flexibility of G protein-coupled receptors has been an obstacle to obtaini ...

Regulation of transmitter release by Ca2+ and synaptotagmin: insights from a large CNS synapse

Ralf Schneggenburger, Olexiy Kochubey

Transmitter release at synapses is driven by elevated intracellular Ca2+ concentration (Ca2+) near the sites of vesicle fusion. Ca2+ signals of profoundly different amplitude and kinetics drive the phasic release component during a presynaptic ac ...

Interaction between Facilitation and Depression at a Large CNS Synapse Reveals Mechanisms of Short-Term Plasticity

Ralf Schneggenburger, Olexiy Kochubey, Martin Guillermo Mueller

The two fundamental forms of short-term plasticity, short-term depression and facilitation, coexist at most synapses, but little is known about their interaction. Here, we studied the interplay between short-term depression and facilitation at calyx of Hel ...

A limited contribution of Ca2+ current facilitation to paired-pulse facilitation of transmitter release at the rat calyx of Held

Ralf Schneggenburger, Martin Guillermo Mueller

Recent studies have suggested that transmitter release facilitation at synapses is largely mediated by presynaptic Ca2+ current facilitation, but the exact contribution of Ca2+ current facilitation has not been determined quantitatively. Here, we determine ...
