Acute myocardial infarction (AMI) triggers sterile inflammatory reaction mediated by prostaglandin E2 (PGE2). Tang et al. show that the PGE2 via its receptor EP3 promotes cardiac healing after AMI by recruiting reparative Ly6Clowmonocytes/macrophages, which is mediated by TGF-β-driven regulation of CX3CR1 expression and VEGF secretion.
