Molecular mechanisms underlying neurotransmitter release

J Rizo - Annual Review of Biophysics, 2022 - annualreviews.org
Major recent advances and previous data have led to a plausible model of how key proteins
mediate neurotransmitter release. In this model, the soluble N-ethylmaleimide-sensitive …

Vesicle trafficking and vesicle fusion: mechanisms, biological functions, and their implications for potential disease therapy

L Cui, H Li, Y Xi, Q Hu, H Liu, J Fan, Y Xiang… - Molecular …, 2022 - Springer
Intracellular vesicle trafficking is the fundamental process to maintain the homeostasis of

An active vesicle priming machinery suppresses axon regeneration upon adult CNS injury

BJ Hilton, A Husch, B Schaffran, T Lin, ER Burnside… - Neuron, 2022 - cell.com
Axons in the adult mammalian central nervous system fail to regenerate after spinal cord
injury. Neurons lose their capacity to regenerate during development, but the intracellular …

Mechanisms of synaptic vesicle exo-and endocytosis

S Mochida - Biomedicines, 2022 - mdpi.com
Within 1 millisecond of action potential arrival at presynaptic terminals voltage–gated Ca2+
channels open. The Ca2+ channels are linked to synaptic vesicles which are tethered by …

Synaptic secretion and beyond: targeting synapse and neurotransmitters to treat neurodegenerative diseases

Z Wei, M Wei, X Yang, Y Xu, S Gao… - Oxidative Medicine and …, 2022 - Wiley Online Library
The nervous system is important, because it regulates the physiological function of the body.
Neurons are the most basic structural and functional unit of the nervous system. The …

On the difficulties of characterizing weak protein interactions that are critical for neurotransmitter release

J Rizo, G David, ME Fealey, K Jaczynska - FEBS Open Bio, 2022 - Wiley Online Library
The mechanism of neurotransmitter release has been extensively characterized, showing
that vesicle fusion is mediated by the SNARE complex formed by syntaxin‐1, SNAP‐25 and …

Novel types of frequency filtering in the lateral perforant path projections to dentate gyrus

J Quintanilla, Y Jia, JC Lauterborn… - The Journal of …, 2022 - Wiley Online Library
Despite its evident importance to learning theory and models, the manner in which the
lateral perforant path (LPP) transforms signals from entorhinal cortex to hippocampus is not …

Interdomain dynamics via paramagnetic NMR on the highly flexible complex calmodulin/Munc13-1

N Karschin, S Becker, C Griesinger - Journal of the American …, 2022 - ACS Publications
Paramagnetic NMR constraints are very useful to study protein interdomain motion, but their
interpretation is not always straightforward. On the example of the particularly flexible …

Phorbolester-activated Munc13-1 and ubMunc13-2 exert opposing effects on dense-core vesicle secretion

S Houy, JS Martins, N Lipstein, JB Sørensen - Elife, 2022 - elifesciences.org
Munc13 proteins are priming factors for SNARE-dependent exocytosis, which are activated
by diacylglycerol (DAG)-binding to their C1-domain. Several Munc13 paralogs exist, but …

Synapse type-specific molecular nanoconfigurations of the presynaptic active zone in the hippocampus identified by systematic nanoscopy

H Sakamoto, N Kimpara, S Namiki, S Hamada… - bioRxiv, 2022 - biorxiv.org
Neurotransmitters are released by exocytosis from synaptic vesicles at the active zone in the
presynaptic terminal. The scaffold of the active zone consists of only a few evolutionarily …
