    Aims. Transient receptor potential melastatin 2(TRPM2) is a Ca^<2+-> permeable nonselective cation channel activated by oxidative stress, and is expressed in neutrophils and cardiomyocytes. This study examined whether TRPM2 contributes to myocardial ischemia-reperfusion(I/R) injury, in which acute inflammation with oxidative stress is closely involved. Methods and Results. Wild-type(Trpm2^<+/+>) and Trpm2 knockout(Trpm2^<-/->) mice were exposed to I/R by ligation of the left coronary artery. Myocardial infarction following I/R but not ischemia alone was reduced in Trpm2^<-/-> mice compared to Trpm2^<+/+> mice, and cardiac contractile function was also improved in Trpm2^<-/-> mice. Moreover, neutrophil accumulation in the reperfused area was lowered in Trpm2^<-/-> mice. When Trpm2^<+/+> or Trpm2^<-/-> polymorphonuclear leukocytes(PMNs) were administered to the Trpm2^<-/-> heart ex vivo through perfusate or in vivo by intravenous injection, Trpm2^<+/+> PMNs induced more severe cardiac injury following I/R compared with Trpm^<2-/-> PMNs. In Trpm2^<+/+> but not in Trpm2^<-/-> PMNs, the combination of H_2O_2 and leukotriene B_4(LTB_4) resulted in enhancement of the increase in intracellular Ca^<2+> and their adhesion to endothelial cells. Conclusions. These findings indicate that TRPM2 is implicated in the development of myocardial reperfusion injury. Accumulation of neutrophils in the heart triggered by activation of neutrophil TRPM2 by H_2O_2 and LTB_4 is likely to have a crucial role in myocardial I/R injury.
