The E3 ligase Thin controls homeostatic plasticity through neurotransmitter release repression

eLife, 2022
Synaptic proteins and synaptic transmission are under homeostatic control, but the relationship between these two processes remains enigmatic. Here, we systematically investigated the role of E3 ubiquitin ligases, key regulators of protein degradation ...

An in vivo biosensor for neurotransmitter release and in situ receptor activity. [PDF]

, 2010
Tools from molecular biology, combined with in vivo optical imaging techniques, provide new mechanisms for noninvasively observing brain processes. Current approaches primarily probe cell-based variables, such as cytosolic calcium or membrane potential ...

Conserved arginine residues in synaptotagmin 1 regulate fusion pore expansion through membrane contact

Nature Communications, 2021
Synaptotagmin 1 (Syt1) is the calcium sensor for fast synchronous neurotransmitter release but the mechanism by which it functions is still under debate.

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.

Amyloid-β acts as a regulator of neurotransmitter release disrupting the interaction between synaptophysin and VAMP2. [PDF]

, 2012
BACKGROUND: It is becoming increasingly evident that deficits in the cortex and hippocampus at early stages of dementia in Alzheimer's disease (AD) are associated with synaptic damage caused by oligomers of the toxic amyloid-β peptide (Aβ42).

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

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

New Aspects of Neurotransmitter Releasee and Exocytosis: Regulation of Neurotransmitter Release by Phosphorylation

Journal of Pharmacological Sciences, 2003
: Synaptic transmission is conducted by neurotransmitters released from nerve terminals. Neurotransmitter release is regulated both positively and negatively by multiple mechanisms, and its regulation is believed to be one of the important mechanisms of ...

Acid-sensing ion channels 1a (ASIC1a) inhibit neuromuscular transmission in female mice [PDF]

, 2014
Acid-sensing ion channels (ASIC) open in response to extracellular acidosis. ASIC1a, a particular subtype of these channels, has been described to have a postsynaptic distribution in the brain, being involved not only in ischemia and epilepsy, but also ...

Synaptic proteins promote calcium-triggered fast transition from point contact to full fusion. [PDF]

, 2012
The molecular underpinnings of synaptic vesicle fusion for fast neurotransmitter release are still unclear. Here, we used a single vesicle-vesicle system with reconstituted SNARE and synaptotagmin-1 proteoliposomes to decipher the temporal sequence of ...
