Regulation and pharmacology of the mitochondrial permeability transition pore.
The 'mitochondrial permeability transition', characterized by a sudden induced change of the inner mitochondrial membrane permeability for water as well as for small substances (</=1.5 kDa), has been known for three decades. Research interest in the entity responsible for this phenomenon, the 'mitochondrial permeability transition pore' (mPTP), has dramatically increased after demonstration tha...
متن کاملMitochondrial Permeability Transition in Rat
42 Onset of the mitochondrial permeability transition (MPT) is the penultimate event 43 leading to lethal cellular ischemia/reperfusion injury, but the mechanisms precipitating 44 the MPT after reperfusion remain unclear. Here, we investigated the role of 45 mitochondrial free Ca and reactive oxygen species (ROS) in pHand MPT-dependent 46 reperfusion injury to hepatocytes. Cultured rat hepatocy...
متن کاملPostconditioning inhibits mitochondrial permeability transition.
BACKGROUND Brief periods of ischemia performed just at the time of reperfusion can reduce infarct size, a phenomenon called "postconditioning." After reflow, opening of the mitochondrial permeability transition pore (mPTP) has been involved in lethal reperfusion injury. We hypothesized that postconditioning may modulate mPTP opening. METHODS AND RESULTS Anesthetized open-chest rabbits underwe...
متن کاملThe mitochondrial permeability transition pore.
This chapter reviews recent advances in the identification of the structural elements of the permeability transition pore. The discovery that cyclosporin A (CsA) inhibits the pore proved instrumental. Various approaches indicate that CsA blocks the pore by binding to cyclophilin (CyP)-D. In particular, covalent labelling of CyP-D in situ by a photoactive CsA derivative has shown that pore ligan...
