Effective postinfarction repair requires timely suppression of innate immune signals to prevent the catastrophic consequences of uncontrolled inflammation on cardiac geometry and function. In macrophages, interleukin-1 receptor-associated kinase (IRAK)-M acts as a functional decoy preventing uncontrolled toll-like receptor /interleukin-1-mediated responses. Our study investigates the role of IRAK-M as a negative regulator of the postinfarction inflammatory response and as a modulator of cardiac remodeling.
