We therefore investigated the role of OGG1 in the pristane-induced lupus (PIL) mouse model of IFN-driven SLE, which recapitulates numerous human SLE manifestations, including elevated type I IFNs, autoantibody generation, arthritis, and severe glomerulonephritis (17, 18). The gene discussed is OGG1; the disease is systemic lupus erythematosus.
