reported that mitochondrial dysfunction in macrophages, induced by deletion of Ndufs4, which encodes NADH dehydrogenase, one of the components of the mitochondrial membrane respiratory chain, increased cell death among infiltrated macrophages and decreased numbers of both Ly6Chi and reparative CD206+ macrophages on days 3 and 7 after myocardial infarction (30). The gene discussed is MRC1; the disease is myocardial infarction.
