Abstract
Protease-activated receptors (PARs) are a family of G-protein-coupled receptors with a unique activation mechanism via cleavage by the serine proteases of the coagulation cascade, immune cell-released proteases, and proteases from pathogens. Pathogens, such as viruses and bacteria, cause myocarditis and heart failure and PAR1 was shown to positively regulate the anti-viral innate immune response via interferon β during virus-induced myocarditis. In contrast, PAR2 negatively regulated the innate immune response and inhibited the interferon β expression. Thus, PARs play a central role for the innate immune response in the heart.
