Secretory Vesicles Targeted to Plasma Membrane During Pollen Germination and Tube Growth [PDF]
Frontiers in Cell and Developmental Biology, 2021 Pollen germination and pollen tube growth are important biological events in the sexual reproduction of higher plants, during which a large number of vesicle trafficking and membrane fusion events occur.

ATP: The crucial component of secretory vesicles. [PDF]
Proc Natl Acad Sci U S A, 2016 Significance ATP is highly concentrated in secretory vesicles. In vitro experiments suggest that the association of ATP with catecholamines reduces their osmotic forces, permitting the extraordinary accumulation of amines within chromaffin granules. However, this has yet to be proved in living cells. Because functional cells cannot be

Revisiting fungal polarized growth: from Spitzenkörper to crescent accumulation of secretory vesicles [PDF]
iScienceSummary: Polarized elongation in filamentous fungi depends on secretory vesicles being supplied and fusing at the apex. In Ascomycota and Basidiomycota, these vesicles have mostly been reported to accumulate into a spheroidal structure known as the ...

Insulator-based dielectrophoresis-assisted separation of insulin secretory vesicles [PDF]
eLifeOrganelle heterogeneity and inter-organelle contacts within a single cell contribute to the limited sensitivity of current organelle separation techniques, thus hindering organelle subpopulation characterization.

Docking of secretory vesicles is syntaxin dependent.
PLoS ONE, 2006 Secretory vesicles dock at the plasma membrane before they undergo fusion. Molecular docking mechanisms are poorly defined but believed to be independent of SNARE proteins.

Observations of calcium dynamics in cortical secretory vesicles. [PDF]
Cell Calcium, 2012 Calcium (Ca(2+)) dynamics were evaluated in fluorescently labeled sea urchin secretory vesicles using confocal microscopy. 71% of the vesicles examined exhibited one or more transient increases in the fluorescence signal that was damped in time. The detection of transient increases in signal was dependent upon the affinity of the fluorescence indicator;

High-throughput screening system for dynamic monitoring of exocytotic vesicle trafficking in mast cells. [PDF]
PLoS ONE, 2018 Mast cells, in addition to endocrine cells and neurons, are typical secretory cells. Their function in allergic inflammation is to secrete inflammatory mediators from secretory vesicles. Intracellular synthesized inflammatory mediators are transported by

Direct imaging of RAB27B-enriched secretory vesicle biogenesis in lacrimal acinar cells reveals origins on a nascent vesicle budding site. [PDF]
PLoS ONE, 2012 This study uses YFP-tagged Rab27b expression in rabbit lacrimal gland acinar cells, which are polarized secretory epithelial cells, to characterize early stages of secretory vesicle trafficking.
