Mitochondrial Permeability Transition Pore

A multiprotein inner mitochondrial complex which opens only under certain pathological conditions (e.g., OXIDATIVE STRESS) uncoupling the membrane leading to APOPTOSIS and MITOCHONDRIAL TRANSMEMBRANE PERMEABILITY-DRIVEN NECROSIS particularly in CARDIOMYOCYTES during MYOCARDIAL REPERFUSION INJURY.
