The rab3A-22A chimera prevents sperm exocytosis by stabilizing open fusion pores [PDF]

open access: yes, 2016
At the final stage of exocytotis, a fusion pore opens between the plasma and a secretory vesicle membranes; typically, when the pore dilates the vesicle releases its cargo.

Multi‐Omics Signatures of Organ Clocks in Biological Aging and Disease: A Conceptual Framework for Organ‐Specific Aging Clocks

open access: yesAging Cell, Volume 25, Issue 5, May 2026.
Organ‐specific aging clocks integrating genomics, epigenomics, transcriptomics, proteomics, and metabolomics offer a more accurate assessment of biological aging than single‐omics approaches. This review proposes a multi‐omics framework emphasizing tissue data, longitudinal study designs, and clinically meaningful training outcomes to advance the ...

RETRACTED: Protein kinase C is a calcium sensor for presynaptic short-term plasticity

open access: yeseLife, 2014
In presynaptic boutons, calcium (Ca2+) triggers both neurotransmitter release and short-term synaptic plasticity. Whereas synaptotagmins are known to mediate vesicle fusion through binding of high local Ca2+ to their C2 domains, the proteins that sense ...

Capsaicin protects neuromuscular junctions from the inhibitory effects of botulinum neurotoxin A [PDF]

open access: yes, 2008
Within 24 hrs after injecting botulinum neurotoxin A (BoNT/A) into the hindlimb, mice lost the toe spread reflex and developed progressive muscle weakness. At the same time, the compound muscle action potential amplitude decreased. Injection of capsaicin

Dynamin Is Functionally Coupled to Insulin Granule Exocytosis [PDF]

open access: yes, 2007
The insulin granule integral membrane protein marker phogrin-green fluorescent protein was co-localized with insulin in Min6B1 beta-cell secretory granules but did not undergo plasma membrane translocation following glucose stimulation.

Molecular insights into electroreceptor ribbon synapses from differential gene expression in sturgeon lateral line organs

open access: yesJournal of Anatomy, Volume 248, Issue 5, Page 784-805, May 2026.
The expression of various genes involved in synapse development, stability and/or function was studied in developing mechanosensory neuromasts and electrosensory ampullary organs in sterlet sturgeon. Most were shared, including Slc17a8, Slc1a3 and Nrxn3, but Cbln18 was neuromast‐restricted and Tulp1 was ampullary organ‐restricted.

CSF synaptic protein concentrations are raised in those with atypical Alzheimer’s disease but not frontotemporal dementia

open access: yesAlzheimer’s Research & Therapy, 2019
Background Increased CSF levels of a number of synaptic markers have been reported in Alzheimer’s disease (AD), but little is known about their concentrations in frontotemporal dementia (FTD). We investigated this in three synaptic proteins, neurogranin,

Distinct insulin granule subpopulations implicated in the secretory pathology of diabetes types 1 and 2

open access: yeseLife, 2020
Insulin secretion from β-cells is reduced at the onset of type-1 and during type-2 diabetes. Although inflammation and metabolic dysfunction of β-cells elicit secretory defects associated with type-1 or type-2 diabetes, accompanying changes to insulin ...

Manipulation of lipid rafts in neuronal cells [PDF]

open access: yes, 2010
Lipid rafts are specialized plasma membrane micro-domains highly enriched in cholesterol, sphingolipids and glycosylphosphatidylinositol (GPI) anchored proteins.

Triple Function of Synaptotagmin 7 Ensures Efficiency of High-Frequency Transmission at Central GABAergic Synapses

open access: yesCell Reports, 2017
Synaptotagmin 7 (Syt7) is thought to be a Ca2+ sensor that mediates asynchronous transmitter release and facilitation at synapses. However, Syt7 is strongly expressed in fast-spiking, parvalbumin-expressing GABAergic interneurons, and the output synapses
