[Problem of end-effector of ischemic postconditioning of the heart].

Analysis of literature source indicates that main pretenders to the role of end-effectors of ischemic postconditioning of the heart are: 1) Ca(2+)-dependent K+ channel of BK-type (big conductance K+ channel), 2) mitoK(ATP) channel (mitochondrial ATP-sensitive K(+)-channel), 3) MPT pore (mitochondrial permeability transition pore). At the same time, some investigators consider that mitoK(ATP) channel is only an intermediate link in the series of signaling events ensured an increase in cardiac tolerance to impact of ischemia-reperfusion. The most likely end-effector of the three structures is MPT pore. Alternatively, it is possible, that unique molecular complex appearing a single end-effector of postconditioning does not exist. Perhaps, that there are several effectors ensured cardioprotective effect of adaptive phenomenon of postconditioning.
