acrosome reaction
Nota
- The acrosome reaction involves fusion of outer and inner membranes of acrosomal membranes. It is rapidly triggered by zona-receptor interaction and involves calcium uptake which induces changes in membrane potentials, modifications in pH, swelling and the release of acrosomal enzymes. This increase of intracellular calcium can be achieved in vitro by exposing spermatozoa to calcium ionophores or phosphodiesterase inhibitors. The acrosome reaction is accompanied by modifications in sperm plasma membrane, which exposes receptors for zona binding and possibly factors exposed on the equatorial segment in preparation for sperm-oocyte fusion.
