ESCRT (endosomal sorting complex required for transport) machinery is essential for acrosomal exocytosis in human sperm
(Society for the Study of Reproduction, 2015-11)
The sperm acrosome reaction is a unique, regulated exocytosis characterized by the secretion of the acrosomal content and the release of hybrid vesicles formed by patches of the outer acrosomal and plasma membranes. In ...
Acrosomal swelling is triggered by camp downstream of the opening of store-operated calcium channels during acrosomal exocytosis in human sperm
(Society for the Study of Reproduction, 2016-03)
Acrosomal exocytosis in mammalian sperm is a regulated secretion with unusual characteristics. One of its most striking features is the postfusion loss of the outer acrosomal membrane and the overlying plasma membrane as ...
Kinetics of human sperm acrosomal exocytosis
(Oxford University Press, 2014-09-01)
The acrosome reaction is a unique event in the lifespan of sperm characterized by the exocytosis of the acrosomal content and the release of hybrid vesicles formed by patches of the outer acrosomal membrane and the plasma ...
Acrosomal biogenesis in human globozoospermia: Immunocytochemical, ultrastructural and proteomic studies
(Oxford University Press, 2012-06)
Background Acrosome biogenesis is a key event in sperm differentiation that depends on the proper interaction between the Golgi complex and the nuclear envelope of early spermatids. We studied the development, structure ...
Targeting and fusion proteins during mammalian spermiogenesis
(Sociedad de Biología de Chile, 2001)
Modification of the spermatic structure of the crab cancer setosus (molina, 1782) (decapoda: brachyura) during induced acrosomal reaction
(UNIV CATOLICA DE VALPARAISO, 2011)
The spermatozoon of Cancer setosus consists of a spherical acrosome and a cup-shaped nucleus surrounding the lowest zone of the acrosome and widening at the equatorial area of the acrosome. The spermatozoa extracted from ...
Microtubule configuration and its relationship to sperm morphology in mammalian spermiogenesis
(2008)
The acrosome is a secretory vesicle located in the mammalian sperm head. Its main function is to transport hydrolytic enzymes. These enzymes will dissolve the zona pellucid, assisting the sperm in fertilizing the egg. The ...
