MIF and myocardial infarction: MIF is a structurally unique inflammatory cytokine that controls cellular signaling in human physiology and disease.[10] It is critically involved in myocardial infarction and exhibits both intracellular properties as well as extracellular, receptor mediated chemokine functions.[11–13] Besides acting as an inflammatory cytokine, MIF also exhibits chemokine like functions and was found to bind to the chemokine receptors CXCR2 and CXCR4 and trigger leukocyte recruitment.
