Transient Receptor Potential Vanilloid 1 Regulates Mitochondrial Membrane Potential and Myocardial Reperfusion Injury

Background The transient receptor potential vanilloid 1 ( TRPV 1) mediates cellular responses to pain, heat, or noxious stimuli by calcium influx; however, the cellular localization and function of TRPV 1 in the cardiomyocyte is largely unknown. We studied whether myocardial injury is regulated by TRPV 1 and whether we could mitigate reperfusion injury by limiting the calcineurin interaction with TRPV 1. Methods and Results In primary...
