Caveolin-1 deficiency impairs synaptic transmission in hippocampal neurons
In addition to providing structural support, caveolin-1 (Cav1), a component of lipid rafts, including caveolae, in the plasma membrane, is involved in various cellular mechanisms, including signal transduction. Although pre-synaptic membrane dynamics and

Synaptic vesicle endocytosis [PDF]
Exocytosis of synaptic vesicles is followed rapidly by reinternalization and recycling of their membranes. Recent studies have confirmed the key role of clathrin-mediated endocytosis in synaptic vesicle reformation and have identified new proteins that participate in this process.

TRPM7 is critical for short-term synaptic depression by regulating synaptic vesicle endocytosis
Transient receptor potential melastatin 7 (TRPM7) contributes to a variety of physiological and pathological processes in many tissues and cells. With a widespread distribution in the nervous system, TRPM7 is involved in animal behaviors and neuronal ...

A delay in vesicle endocytosis by a C-terminal fragment of N-cadherin enhances Aβ synaptotoxicity
Synaptotoxic Aβ oligomers are thought to play a major role in the early pathology of Alzheimer´s disease (AD). However, the molecular mechanisms involved in Aβ-induced synaptic dysfunction and synapse damage remain largely unclear.

Astroglial Connexin 43 Regulates Synaptic Vesicle Release at Hippocampal Synapses
Connexin 43, an astroglial gap junction protein, is enriched in perisynaptic astroglial processes and plays major roles in synaptic transmission. We have previously found that astroglial Cx43 controls synaptic glutamate levels and allows for activity ...

Synaptotagmin 1 oligomers clamp and regulate different modes of neurotransmitter release [PDF]
Release of neurotransmitters relies on submillisecond coupling of synaptic vesicle fusion to the triggering signal: AP-evoked presynaptic Ca2+ influx.

Incomplete vesicular docking limits synaptic strength under high release probability conditions
Central mammalian synapses release synaptic vesicles in dedicated structures called docking/release sites. It has been assumed that when voltage-dependent calcium entry is sufficiently large, synaptic output attains a maximum value of one synaptic ...

Synaptic vesicles store neurotransmitters and fuse with the pre-synaptic membrane when an action potential arrives at the nerve terminal. Here authors apply cross-linking mass spectrometry to study interactions of synaptic vesicle proteins and describe a

Synaptic Vesicle Exocytosis [PDF]
Presynaptic nerve terminals release neurotransmitters by synaptic vesicle exocytosis. Membrane fusion mediating synaptic exocytosis and other intracellular membrane traffic is affected by a universal machinery that includes SNARE (for "soluble NSF-attachment protein receptor") and SM (for "Sec1/Munc18-like") proteins.

Localization and mobility of synaptic vesicles in Myosin VI mutants of Drosophila. [PDF]
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.
