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 کاملMethanol extract and fraction of Anchomanes difformis root tuber modulate liver mitochondrial membrane permeability transition pore opening in rats
Objective: Extracts of Anchomanes difformis (AD) are used in folkloric medicine to treat several diseases and infections. However, their roles in mitochondrial permeability transition pore opening are not known. Material and Methods: The viability of mitochondria isolated from Wistar rat liver used in this experiment, was assessed by monitoring their swel...
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 کاملThe mitochondrial permeability transition pore: a mystery solved?
The permeability transition (PT) denotes an increase of the mitochondrial inner membrane permeability to solutes with molecular masses up to about 1500 Da. It is presumed to be mediated by opening of a channel, the permeability transition pore (PTP), whose molecular nature remains a mystery. Here I briefly review the history of the PTP, discuss existing models, and present our new results indic...
