macrophage migration inhibitory factor


macrophage migration inhibitory factor

A 25-kD proinflammatory lymphokine, produced by T cells in response to antigenic stimulus, which inhibits macrophage migration.
Gene
MMIF is encoded by MIF on chromosome 22q11.23.
Activities
Cell-mediated immunity, inflammation and regulation of macrophage function in host defence by suppressing the anti-inflammatory effects of glucocorticoids.
 
Mechanism
Increases intracellular cAMP, polymerises microtubules, stops macrophage progression.
