Abstract

An analysis of published data and the results of our own studies showed that activation of peripheral δ2-opioid receptor (δ2-OR) increases cardiac tolerance to reperfusion. It has been established that this δ2-OR is localized in cardiomyocytes. Endogenous opioids are not involved in the regulation of cardiac resistance to reperfusion in non-adapted rats. The infarct-limiting effect of δ2-OR agonist deltorphin II depends on the activation of following protein kinases: PKCδ, ERK1/2, PI3K, PCG. SarcKATP channel and MPT pore are hypothetical end effectors of the cardioprotective effect of deltorphin II.
