It is postulated that IP induces the release of endogenous protective molecules that interact with cognate receptors to activate PLC through mediation of the chincough virus sensitive proteins. PLC hydrolyzes membrane phospholipid and produces diacylglyccerol,that,by working together with calcium hydronium,translocates PKC from cytoplasm to cell membrane and activates PKC.

推测缺血预处理细胞保护作用机制是：缺血预处理引起内源性保护物质释放，作用于细胞膜上的相应受体，通过百日咳病毒敏感性G蛋白的介导而激活磷脂酶，磷脂酶水解膜磷脂，产生二酰基甘油(diacylglyccerol，DAG)，DAG和Ca2+协同作用于PKC，使其从胞浆转位到细胞膜并且被活化，PKC在膜上使底物蛋白磷酸化，引发一系列相关信号转导通路的激活，调控保护性基因的表达，从而提高细胞对缺血再灌注损伤的耐受性。

The destruction of ozone molecules in the ozone layer by chemical reaction with materials released from human activities, including chlorofluorocarbons and halons.
