PHluorin-conjugated secondary nanobodies as a tool for measuring synaptic vesicle exo- and endocytosis

Authors Georgiev SV, Rizzoli SO Journal BioRxiv Citation bioRxiv 2024.09.23.614406. Abstract Neuronal communication relies on synaptic vesicle recycling, which has long been investigated by live imaging approaches. Synapto-pHluorins, genetically encoded reporters that incorporate a pH-sensitive variant of GFP within the lumen of the synaptic vesicle, have been especially popular. However,

Power-law adaptation in the presynaptic vesicle cycle

Authors Mikulasch FA, Georgiev SV, Rudelt L, Rizzoli S, Priesemann V Journal BioRxiv Citation bioRxiv 2024.07.19.604253. Abstract After synaptic transmission, fused synaptic vesicles are recycled, enabling the synapse to recover its capacity for renewed release. The recovery steps, which range from endocytosis to vesicle docking and priming, have been studied

Calcium-triggered (de)ubiquitination events in synapses

Authors Ainatzi S, Kaufmann SV, Silbern I, Georgiev SV, Lorenz S, Rizzoli SO, Urlaub H Journal BioRxiv Citation bioRxiv 2024.07.04.602026. Abstract Neuronal communication relies on neurotransmitter release from synaptic vesicles (SVs), whose dynamics are controlled by calcium-dependent pathways, as many thoroughly studied phosphorylation cascades. However, little is known about other
