Haploinsufficiency of NADPH Oxidase Subunit Neutrophil Cytosolic Factor 2 Is Sufficient to Accelerate Full-Blown Lupus in NZM 2328 Mice.

ABSTRACT:

Objective

We have previously established that the gene for neutrophil cytosolic factor 2 (NCF-2) predisposes to lupus, and we have identified lupus patients with point mutations that are predicted to cause reduced NADPH oxidase activity. We undertook this study to investigate the relationship between reduced leukocyte NADPH oxidase activity and immune dysregulation associated with systemic lupus erythematosus (SLE).

Methods

We generated NCF-2-null mice, in which NADPH oxidase activity is absent, on the nonautoimmune C57BL/6 (B6) mouse background and on the NZM 2328 mouse background, a polygenic model in which mice spontaneously develop lupus. Clinical disease, serology, and immunopathology were evaluated.

Results

NCF-2-null mice on the B6 background were susceptible t
