Rab3A, a possible marker of cortical granules, participates in cortical granule exocytosis in mouse eggs
(Elsevier Inc, 2016-09)
Fusion of cortical granules with the oocyte plasma membrane is the most significant event to prevent polyspermy. This particular exocytosis, also known as cortical reaction, is regulated by calcium and its molecular mechanism ...
Thapsigargin stimulates acrosomal exocytosis in hamster spermatozoa
(1998)
Thapsigargin (TG), a plant-derived sesquiterpene lactone, inhibits several isoforms of both the sarcoplasmic and endoplasmic reticulum Ca 2+- ATPases. Thus, intracellular Ca 2+ stores found in the endoplasmic reticulum can ...
Recent advances in chromaffin cell biology: Summing up the last International Symposium on Chromaffin Cell Biology
(Sociedad de Biología de Chile, 2004)
Noise Exposure Potentiates Exocytosis From Cochlear Inner Hair Cells
(Frontiers Media, 2021-09-29)
Noise-induced hearing loss has gained relevance as one of the most common forms of hearing impairment. The anatomical correlates of hearing loss, principally cell damage and/or death, are relatively well-understood ...
Ceramide induces a multicomponent intracellular calcium increase triggering the acrosome secretion in human sperm
(Elsevier Science, 2020-07)
Exocytosis of spermatozoon's secretory vesicle, named acrosome reaction (AR), is a regulated event that plays a central role in fertilization. It is coupled to a complex calcium signaling. Ceramide is a multitasking lipid ...
Proteomic profiling of the molecular targets of interactions of the mastoparan peptide Protopolybia MP-III at the level of endosomal membranes from rat mast cells
(Wiley-Blackwell, 2012-08-01)
It is well known that the activation of mast cells due to the binding of mastoparan to the Ga subunit of trimeric G proteins involves exocytosis regulation. However, experimental evidence in the literature indicates that ...
Cortical granule exocytosis is mediated by alpha-SNAP and N-Ethilmaleimide sensitive factor in mouse eggs
(Public Library of Science, 2015-08-12)
Cortical granule exocytosis (CGE), also known as cortical reaction, is a calciumregulated secretion that represents a membrane fusion process during meiotic cell division of eggs. The molecular mechanism of membrane fusion ...
How does the stimulus define exocytosis in adrenal chromaffin cells?
(Springer, 2018-01)
The extent and type of hormones and active peptides secreted by the chromaffin cells of the adrenal medulla have to be adjusted to physiological requirements. The chromaffin cell secretory activity is controlled by the ...
A specific transitory increase in intracellular calcium induced by progesterone promotes acrosomal exocytosis in mouse sperm
(Society for the Study of Reproduction, 2016-03-01)
During capacitation, sperm acquire the ability to undergo the acrosome reaction (AR), an essential step in fertilization. Progesterone produced by cumulus cells has been associated with various physiological processes in ...
