Failure of a superoxide generating system, the NADPH oxidase, present in neutrophils and other phagocytes gives rise to chronic granulomatous disease (CGD), a group of single-gene inherited disorders all characterized by an extreme susceptibility to pyogenic infection, with potentially fatal consequences. About 30% of CGD cases are caused by an autosomally inherited deficiency of a 47-Kd cytoplasmic component of the oxidase (p47-phox). Epstein-Barr virus (EBV) immortalized B-lymphocyte lines established from these CGD patients also express this NADPH oxidase defect and consequently are rendered incapable of generating superoxide on stimulation. We have used a p47-phox-deficient EBV-transformed B-cell line as a recipient for retroviral transfer of a functional p47-phox cDNA. The presence and activity of the retrovirally encoded p47-phox in the transduced cells is demonstrated and we show that this restores their capacity to generate superoxide.
