Postnatal developmental changes in the laryngeal chemosensory cell clusters of rats
Chemosensory cell clusters appeared in the rat larynx 2 days after birth and were already connected to afferent nerve fibers. Their number increased until 3 weeks of age, then stabilized while continuing to grow through the addition of new cells. Because their number reached a plateau around the time of weaning, their development may be linked to ...

Synaptotagmin oligomers are necessary and can be sufficient to form a Ca2+-sensitive fusion clamp
The buttressed‐ring hypothesis, supported by recent cryo‐electron tomography analysis of docked synaptic‐like vesicles in neuroendocrine cells, postulates that prefusion SNAREpins are stabilized and organized by Synaptotagmin (Syt) ring‐like oligomers ...

Potyvirus turnip mosaic virus induces neutral lipid accumulation and lipid droplet biogenesis in infected leaves for its own benefit. See also the Commentary on this article by May & Nagy, 252: 525–527. Summary Lipid droplets (LDs), which are dedicated to storing neutral lipids (NLs), are dynamic organelles involved in numerous other functions ...

Summary Neurotransmitter release can be synchronous and occur within milliseconds of action potential invasion, or asynchronous and persist for tens of milliseconds. The molecular determinants of release kinetics remain poorly understood.

PIP4K2A regulates intracellular cholesterol transport through modulating PI(4,5)P2 homeostasis
The transport of LDL-derived cholesterol from lysosomes to peroxisomes is facilitated by membrane contacts formed between the lysosomal protein synaptotagmin VII and the peroxisomal lipid phosphatidylinositol 4, 5-bisphosphate [PI(4,5)P2].

ASXL1 in inflammatory macrophages attenuates renal tubular cell damage through coordinated histone modification of H3K27me3 and H3K4me3 in acute kidney injury. Abstract Macrophages are major contributors to inflammatory responses in acute kidney injury (AKI) and rapidly alter their gene expression through epigenetic regulation.

Synaptotagmin 7 Mediates Both Facilitation and Asynchronous Release at Granule Cell Synapses
When an action potential invades a presynaptic terminal it evokes large, brief Ca2+ signals that trigger vesicle fusion within milliseconds that is followed by a small residual Ca2+ (Cares) signal.

Precision Chemistry for Protein Lysine Modification
Selective modification of lysine residues is challenging due to their similar intrinsic reactivity. Inspired by enzymatic recognition, ligand‐guided electrophiles enable site‐selective labeling and functionalization, while ligand‐guided catalyses achieve regioselective installation of bio‐relevant post‐translational modifications.

Synaptotagmin 17 controls neurite outgrowth and synaptic physiology via distinct cellular pathways
The synaptotagmin (syt) proteins have been widely studied for their role in regulating fusion of intracellular vesicles with the plasma membrane. Here we report that syt-17, an unusual isoform of unknown function, plays no role in exocytosis, and instead

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