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 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 کاملElectrophysiology clarifies the megariddles of the mitochondrial permeability transition pore.
After a brief review of the early history of mitochondrial electrophysiology, the contribution of this approach to the study of the mitochondrial permeability transition (MPT) is recapitulated. It has for example provided evidence for a dimeric nature of the MPT pore, allowed the distinction between two levels of control of its activity, and underscored the relevance of redox events for the phe...
متن کاملIdentifying the components of the elusive mitochondrial permeability transition pore.
The mitochondrial permeability transition pore (MPTP) describes an inducible activity that regulates solute exchange between mitochondrial matrix contents and the surrounding cytoplasm, which acutely leads to loss of mitochondrial inner membrane potential but eventually organelle swelling and rupture. Mitochondrial rupture due to prolonged MPTP engagement, which is often the result of ischemic ...
