Limiting Cardiac Ischemic Injury by Pharmacologic Augmentation of MIF-AMPK Signal Transduction

Background Macrophage migration inhibitory factor (MIF) exerts a protective effect on ischemic myocardium by activating AMP-activated protein kinase (AMPK). Small molecules that increase the affinity of MIF for its receptor have been recently designed, and we hypothesized that such agonists may enhance AMPK activation and limit ischemic tissue injury.
