1 In this study, we examined the role of IRF5 in the pathogenesis of pristane-induced lupus in mice. pristane interferon regulatory factor 5 Mus musculus
2 The pathological response to pristane in IRF5(-/-) mice shared many features with type I IFN receptor (IFNAR)(-/-) and TLR7(-/-) mice: production of anti-Sm/RNP autoantibodies, glomerulonephritis, generation of Ly6C(hi) monocytes, and IFN-I production all were greatly attenuated. pristane interferon regulatory factor 5 Mus musculus
3 Lymphocyte activation following pristane injection was greatly diminished in IRF5(-/-) mice, and Th cell differentiation was deviated from Th1 in wild-type mice toward Th2 in IRF5(-/-) mice. pristane interferon regulatory factor 5 Mus musculus
4 Collectively, these data indicate that altered production of IFN-I and other cytokines in IRF5(-/-) mice prevents pristane from inducing lupus pathology by broadly affecting T and B lymphocyte activation/differentiation. pristane interferon regulatory factor 5 Mus musculus
