This work investigated the functional role of nuclear factor-kappa B (NF-{kappa}B) in respiratory burst activity and in expression of the human phagocyte NADPH oxidase genes CYBB, CYBA, NCF1, and NCF2. U937 cells with a stably transfected repressor of NF-{kappa}B (I-{kappa}B{alpha}-S32A/S36A) demonstrated significantly lower superoxide release and lower CYBB and NCF1 gene expression compared to control U937 cells. We further tested EBV-transformed B cells from patients with anhidrotic ectodermal dysplasia with immunodeficiency (EDA-ID), an inherited disorder of NF-{kappa}B function. Superoxide release and CYBB gene expression by EDA-ID cells were significantly decreased compared to normal cells and similar to X-linked chronic granulomatous disease (X910 CGD) patient cells. NCF1 gene expression in EDA-ID S32I cells was decreased compared to normal control cells and similar to autosomal recessive (A470) CGD cells. Gel shift assays demonstrated loss of recombinant human p50 binding to a NF-{kappa}B site 5' to the CYBB gene in U937 cells treated with NF-{kappa}B inhibitors, repressor-transfected U937 cells, and EDA-ID patients' cells. Zymosan phagocytosis was not affected by transfection of U937 cells with the NF-{kappa}B repressor. These studies show that NF-{kappa}B is necessary for CYBB and NCF1 gene expression and activation of the phagocyte NADPH oxidase in this model system.
