Myocardial ischemia reperfusion injury I/R adversely affects cardiac function. Heat shock proteins (HSPs) are a highly conserved family of proteins with diverse functions expressed by all cells exposed to environmental stress including myocardila injury. We investigated release of small constitutive heat shock proteins (HSPs) from mouse myocardium and the effects of TAT-HSP70 after myocardial I/R via occluding the left coronary artery (LAD). The results support the hypothesis that elevated HSPs in myocardium after ischemia and reperfusion and contributes to the inflammatory mechanism of myocardial functional injury. Further investigation of the significance of HSPs accumulation to the evolution of myocardial injury.
