Synaptic Vesicle Endocytosis in Different Model Systems

open access: yesFrontiers in Cellular Neuroscience, 2018
Neurotransmission in complex animals depends on a choir of functionally distinct synapses releasing neurotransmitters in a highly coordinated manner. During synaptic signaling, vesicles fuse with the plasma membrane to release their contents. The rate of

The involvement of actin, calcium channels and exocytosis proteins in somato-dendritic oxytocin and vasopressin release [PDF]

open access: yes, 2012
Hypothalamic magnocellular neurons release vasopressin and oxytocin not only from their axon terminals into the blood, but also from their somata and dendrites into the extracellular space of the brain, and this can be regulated independently ...

Snare Mediated Vesicle Fusion in Supported Membranes: Comparing Synaptic Vesicles with Reconstituted Vesicles [PDF]

open access: yesBiophysical Journal, 2012
In vitro reconstitution experiments have played an essential role in a large body of research on SNARE-mediated membrane fusion. We and others have developed single vesicle assays to gain more detailed insight into the kinetics of vesicle docking and fusion.

Super‐Refractory Status Epilepticus (SRSE) in a Patient With Compound Heterozygous OPA1 Variants: Case Report and Literature Review

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Super‐Refractory Status Epilepticus (SRSE) is a rare, life‐threatening neurological emergency with unclear etiology in many cases. Mitochondrial dysfunction, often due to disease‐causing genetic variants, is increasingly recognized as a cause, with each gene producing distinct pathophysiological mechanisms.

A Mathematical Model of Tripartite Synapse: Astrocyte Induced Synaptic Plasticity

open access: yes, 2012
In this paper we present a biologically detailed mathematical model of tripartite synapses, where astrocytes modulate short-term synaptic plasticity. The model consists of a pre-synaptic bouton, a post-synaptic dendritic spine-head, a synaptic cleft and ...

Mesenchymal Stem Cell‐Derived Apoptotic Micro‐Vesicles Repaired Sciatic Nerve Defect by Regulating Early Inflammatory Microenvironment and Promoting Angiogenesis

open access: yesAdvanced Healthcare Materials, EarlyView.
HUCMSC‐Apo‐mvs enhance peripheral nerve repair by modulating the inflammatory microenvironment (IME), primarily through coordinated actions on three functional cells. They recruit macrophages and promote their polarization from pro‐inflammatory M1 to anti‐inflammatory M2 phenotypes, increasing secretion of IL‐10 and VEGF.

A new method for isolation and purification of fusion-competent inhibitory synaptic vesicles

open access: yesCurrent Research in Physiology
Synaptic vesicles specific to inhibitory GABA-releasing neurons are critical for regulating neuronal excitability. To study the specific molecular composition, architecture, and function of inhibitory synaptic vesicles, we have developed a new method to ...

The C2A domain of synaptotagmin is an essential component of the calcium sensor for synaptic transmission.

open access: yesPLoS ONE, 2020
The synaptic vesicle protein, synaptotagmin, is the principle Ca2+ sensor for synaptic transmission. Ca2+ influx into active nerve terminals is translated into neurotransmitter release by Ca2+ binding to synaptotagmin's tandem C2 domains, triggering the ...

Real-time three-dimensional tracking of single vesicles reveals abnormal motion and pools of synaptic vesicles in neurons of Huntington's disease mice

open access: yesiScience, 2021
Summary: Although defective synaptic transmission was suggested to play a role in neurodegenerative diseases, the dynamics and vesicle pools of synaptic vesicles during neurodegeneration remain elusive.

Loss of AP-3 function affects spontaneous and evoked release at hippocampal mossy fiber synapses [PDF]

open access: yes, 2006
Synaptic vesicle (SV) exocytosis mediating neurotransmitter release occurs spontaneously at low intraterminal calcium concentrations and is stimulated by a rise in intracellular calcium.
