Abstract

Suppressor of cytokine signaling-1 (SOCS1/JAB) negatively regulates not only the cytokine-signaling pathway but also lipopolysaccharide (LPS)-induced macrophage activation. We found that SOCS1-deficient dendritic cells (DCs) were also hyperresponsive to interferon-γ and interleukin-4. To define the role of SOCS1-deficient DCs in vivo, we generated mice in which the SOCS1 expression was restored in T and B cells on a SOCS1-/- background. In these mice, DCs were accumulated in the thymus and spleen and produced high levels of BAFF/BLyS and APRIL, resulting in the aberrant expansion of B cells and autoreactive antibody production. SOCS1-deficient DCs efficiently stimulated B cell proliferation in vitro and autoantibody production in vivo. These results indicate that SOCS1 plays an essential role in the normal DC functions and suppression of systemic autoimmunity.
