The 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...
متن کاملThe mitochondrial permeability transition pore as a target of cardioprotective signaling.
IT IS HAS BEEN OVER TWO DECADES since Murry and colleagues (15) published their seminal study describing ischemic preconditioning, a phenomenon whereby brief antecedent periods of ischemia-reperfusion profoundly protect the heart against a subsequent lethal period of ischemia and reperfusion. This intrinsic cardioprotective mechanism has been demonstrated in every animal tested, including human...
متن کاملMitochondrial permeability transition pore: an enigmatic gatekeeper
Mitochondrial permeability transition pore (MPTP) is a transient structure formed in the inner mitochondrial membrane (IMM) upon oxidative challenge of the organelle. The transition is a Ca 2+ -dependent increase of permeability of IMM leading to loss of transmembrane potential (∆ψm), mitochondrial swelling and, finally, rupture of outer mitochondrial membrane leading to release of factors caus...
متن کاملMitochondrial permeability transition pore and postconditioning.
Postconditioning has recently been described as a powerful cardioprotection that prevents lethal reperfusion injury. Growing evidence suggests that mitochondrial permeability transition may be a key event in postconditioning. This proposition arises from the complementary observations that: (1) conditions for the mitochondrial permeability transition pore (mPTP) opening are built up during earl...
متن کاملTRO40303, a new cardioprotective compound, inhibits mitochondrial permeability transition.
3,5-Seco-4-nor-cholestan-5-one oxime-3-ol (TRO40303) is a new cardioprotective compound coming from a chemical series identified initially for neuroprotective properties. TRO40303 binds specifically to the mitochondrial translocator protein 18 kDa (TSPO) at the cholesterol site. After intravenous administration, TRO40303 tissue distribution was comparable to that of TSPO, and, in particular, th...
