Differential cargo mobilisation within Weibel-Palade bodies after transient fusion with the plasma membrane. [PDF]

, 2014
Inflammatory chemokines can be selectively released from Weibel-Palade bodies (WPBs) during kiss-and-run exocytosis. Such selectivity may arise from molecular size filtering by the fusion pore, however differential intra-WPB cargo re-mobilisation ...

An inhibitory effect of extracellular Ca2+ on Ca2+-dependent exocytosis. [PDF]

PLoS ONE, 2011
AIM: Neurotransmitter release is elicited by an elevation of intracellular Ca(2+) concentration ([Ca(2+)](i)). The action potential triggers Ca(2+) influx through Ca(2+) channels which causes local changes of [Ca(2+)](i) for vesicle release. However, any

Secretory vesicles are preferentially targeted to areas of low molecular SNARE density [PDF]

, 2012
Intercellular communication is commonly mediated by the regulated fusion, or exocytosis, of vesicles with the cell surface. SNARE (soluble N-ethymaleimide sensitive factor attachment protein receptor) proteins are the catalytic core of the secretory ...

Munc13 mediates klotho-inhibitable diacylglycerol-stimulated exocytotic insertion of pre-docked TRPC6 vesicles.

PLoS ONE, 2020
α-Klotho is a type 1 transmembrane protein that exhibits aging suppression function. The large amino-terminal extracellular domain of α-klotho is shed as soluble klotho (sKlotho) and functions as a circulating cardioprotective hormone.

Exocytosis of serotonin from the neuronal soma is sustained by a serotonin and calcium-dependent feedback loop

Frontiers in Cellular Neuroscience, 2014
The soma of many neurons releases large amounts of transmitter molecules through an exocytosis process that continues for hundreds of seconds after the end of the triggering stimulus.

Estrogen activates endothelial exocytosis

, 2021
Estrogen replacement for post-menopausal women has been proven beneficial and widely used in treating post-menopausal symptoms such as hot flush, vaginal dryness and osteoporosis. However, its cardiovascular benefit is still controversial.

The dynamics of somatic exocytosis in monoaminergic neurons

Frontiers in Physiology, 2012
Some monoaminergic neurons can release neurotransmitters by exocytosis from their cell bodies. The amount of monoamine released by somatic exocytosis can be comparable to that released by synaptic exocytosis, though neither the underlying mechanisms nor ...

Further Characterization of Dopamine Release by Permeabilized PC 12 Cells [PDF]

, 1987
Rat pheochromocytoma cells (PC 12) permeabilized with staphylococcal α-toxin release [3H]dopamine after addition of micromolar Ca2+. This does not require additional Mg2+-ATP (in contrast to bovine adrenal medullary chromaffin cells).

Network-based insights into miRNA regulation of β-cell insulin secretion in type 2 diabetes

iScience
Summary: Increasing evidence suggests that microRNAs (miRNAs) contribute to pancreatic β-cell compensation during type 2 diabetes (T2D) pathogenesis. To examine miRNA-mRNA interactions in human islets and their roles in β-cell insulin secretion and T2D ...
