The p47phox mouse knock-out model of chronic granulomatous disease.
Chronic granulomatous disease (CGD) is caused by a congenital defect in phagocyte reduced nicotinamide dinucleotide phosphate (NADPH) oxidase production of superoxide and related species. It is characterized by recurrent life-threatening bacterial and fungal infections and tissue granuloma formation. We have created a mouse model of CGD by targeted disruption of p47phox, one of the genes in which mutations cause human CGD. Identical to the case in human CGD, leukocytes from p47phox-/- mice produced no superoxide and killed staphylococci ineffectively. p47phox-/- mice developed lethal infections and granulomatous inflammation similar to those encountered in human CGD patients. This model mirrors human CGD and confirms a critical role for the phagocyte NADPH oxidase in mammalian host defense.
