Protocol for Quantitative Analysis of Synaptic Vesicle Clustering in Axons of Cultured Neurons

open access: yesSTAR 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 ...

Quantitative Analysis Linking Inner Hair Cell Voltage Changes and Postsynaptic Conductance Change: A Modelling Study [PDF]

open access: yes, 2015
This paper presents a computational model which estimates the postsynaptic conductance change of mammalian Type I afferent peripheral process when airborne acoustic waves impact on the tympanic membrane. A model of the human auditory periphery is used to

Vesicular GABA Uptake Can Be Rate Limiting for Recovery of IPSCs from Synaptic Depression

open access: yesCell 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 ...

A mouse model of autism implicates endosome pH in the regulation of presynaptic calcium entry. [PDF]

open access: yes, 2018
Psychoactive compounds such as chloroquine and amphetamine act by dissipating the pH gradient across intracellular membranes, but the physiological mechanisms that normally regulate organelle pH remain poorly understood.

The presynaptic ribbon maintains vesicle populations at the hair cell afferent fiber synapse [PDF]

open access: yes, 2018
The ribbon is the structural hallmark of cochlear inner hair cell (IHC) afferent synapses, yet its role in information transfer to spiral ganglion neurons (SGNs) remains unclear.

The synaptic vesicle proteome [PDF]

open access: yesJournal of Neurochemistry, 2007
AbstractSynaptic vesicles are key organelles in neurotransmission. Vesicle integral or membrane‐associated proteins mediate the various functions the organelle fulfills during its life cycle. These include organelle transport, interaction with the nerve terminal cytoskeleton, uptake and storage of low molecular weight constituents, and the regulated ...

Specific disruption of hippocampal mossy fiber synapses in a mouse model of familial Alzheimer's disease. [PDF]

open access: yes, 2014
The earliest stages of Alzheimer's disease (AD) are characterized by deficits in memory and cognition indicating hippocampal pathology. While it is now recognized that synapse dysfunction precedes the hallmark pathological findings of AD, it is unclear ...

Synaptophysin and synaptoporin expression in the developing rat olfactory system [PDF]

open access: yes, 1993
The expressions of two closely related synaptic vesicle antigens synaptophysin and synaptoporin were examined in the olfactory system of the adult rat and during pre- and postnatal development.

Long Term Potentiation (LTP) and Long Term Depression (LTD) Cause Differential Spatial Redistribution of the Synaptic Vesicle Protein Synaptophysin in the Middle Molecular Layer of the Dentate Gyrus in Rat Hippocampus [PDF]

open access: yes, 2016
The presynaptic modifications that accompany long-term changes in synaptic plasticity are still not fully understood. Synaptophysin is a major synaptic vesicle protein involved in neurotransmitter release. We have used quantitative electron microscopy to

Mechanisms of synaptic depression at the hair cell ribbon synapse that support auditory nerve function [PDF]

open access: yes, 2017
Inner hair cells (IHCs) in the cochlea are the mammalian phono-receptors, transducing sound energy into graded changes in membrane potentials, the so called “receptor potentials.” Ribbon synapses between IHCs and auditory nerve neurons are responsible ...
