Ca 2 +-dependent PS exposure is from the unidirectional transport of PS to outer membrane through scramblase activation and flippase inhibition. In contrast, apoptotic pathways involve caspase-3-dependent cytoskeleton degradation, membrane blebbing, MP release, and subsequent disruption of lipid asymmetry (Hugel et al., 2005).
Part of the mechanism for ATP release involved Ca 2+ ‐dependent transport and fusion of ATP loaded membrane vesicles to the plasma membrane, which was inhibited by pretreatment with a cell membrane permeable calcium chelating agent or by inhibition of ATP uptake into secretory vesicles with bafilomycin A 1 (O'Grady et al. 2013).
