MIF

MIF, or Macrophage Migration Inhibitory Factor, is a pleiotropic cytokine also known as glycosylation-inhibiting factor or L-dopachrome isomerase. It regulates immune responses by inhibiting macrophage migration, promoting pro-inflammatory cytokine release (e.g., TNF-α, IL-6), and modulating T-cell activation. MIF interacts with signaling pathways like MAPK, PI3K/Akt, and NF-κB, influencing cell survival and proliferation.
Dysregulated MIF expression correlates with inflammatory diseases (rheumatoid arthritis, sepsis), cancer (melanoma, breast cancer), and metabolic disorders. Current drug development focuses on small-molecule inhibitors (e.g., ISO-1, 4-IPP) and neutralizing antibodies to block MIF-CD74 binding, with preclinical studies showing efficacy in reducing inflammation and tumor growth.
