MnSOD competes with NO- to reduce the amount of [O.sub.2.sup.-] and consequently forms more ONOO-, which is released into the cytoplasm via the mtPTP [33, 66, 107, 119-126, 129, 130].
During apoptosis and after PSR is reached, the mtPTP releases cytochrome C from the membrane, activating the caspase cascade and pannexin hemichannels, which release ATP and work as beacons for phagocytic cells.
