Localization and mobility of synaptic vesicles in Myosin VI mutants of Drosophila. [PDF]
PLoS ONE, 2014 BACKGROUND: At the Drosophila neuromuscular junction (NMJ), synaptic vesicles are mobile; however, the mechanisms that regulate vesicle traffic at the nerve terminal are not fully understood.

Synaptic Vesicle Endocytosis [PDF]
Cold Spring Harbor Perspectives in Biology, 2012 Neurons can sustain high rates of synaptic transmission without exhausting their supply of synaptic vesicles. This property relies on a highly efficient local endocytic recycling of synaptic vesicle membranes, which can be reused for hundreds, possibly thousands, of exo-endocytic cycles. Morphological, physiological, molecular, and genetic studies over

Determining the neurotransmitter concentration profile at active synapses [PDF]
, 2009 Establishing the temporal and concentration profiles of neurotransmitters during synaptic release is an essential step towards understanding the basic properties of inter-neuronal communication in the central nervous system.

Frontiers in Cellular Neuroscience, 2023 The Drosophila larval neuromuscular junction (NMJ) is a well-known model system and is often used to study synapse development. Here, we show synaptic degeneration at NMJ boutons, primarily based on transmission electron microscopy (TEM) studies.

Nature Structural & Molecular Biology, 2008 The core of the neurotransmitter release machinery is formed by SNARE complexes, which bring the vesicle and plasma membranes together and are key for fusion, and by Munc18-1, which controls SNARE-complex formation and may also have a direct role in fusion.

Distinct RNA profiles in subpopulations of extracellular vesicles: apoptotic bodies, microvesicles and exosomes [PDF]
, 2013 Introduction: In recent years, there has been an exponential increase in the number of studies aiming to understand the biology of exosomes, as well as other extracellular vesicles.

Spontaneous Vesicle Recycling in the Synaptic Bouton
Frontiers in Cellular Neuroscience, 2014 The trigger for synaptic vesicle exocytosis is Ca2+, which enters the synaptic bouton following action potential stimulation. However, spontaneous release of neurotransmitter also occurs in the absence of stimulation in virtually all synaptic boutons. It

Synaptic vesicle pools: an update [PDF]
Frontiers in Synaptic Neuroscience, 2010 During the last few decades synaptic vesicles have been assigned to a variety of functional and morphological classes or "pools". We have argued in the past (Rizzoli and Betz, 2005) that synaptic activity in several preparations is accounted for by the function of three vesicle pools: the readily releasable pool (docked at active zones and ready to go ...

Vesicular GABA Uptake Can Be Rate Limiting for Recovery of IPSCs from Synaptic Depression
Cell Reports, 2018 Summary: Synaptic efficacy plays crucial roles in neuronal circuit operation and synaptic plasticity. Presynaptic determinants of synaptic efficacy are neurotransmitter content in synaptic vesicles and the number of vesicles undergoing exocytosis at a ...

Protocol for Quantitative Analysis of Synaptic Vesicle Clustering in Axons of Cultured Neurons
STAR Protocols, 2020 Summary: Clustering of synaptic vesicles along the neuronal axons is a critical mechanism underpinning proper synaptic transmission. Here, we provide a detailed protocol for analyzing the distribution of synaptic vesicles in presynaptic boutons of ...
