520 |a Dendritic cells (DC) regulate the activation and differentiation of T cells. They are activated by signals of inflammation and tissue damage, and thus could play a role in the amplification and perpetuation of autoimmune diseases such as systemic lupus erythematosus (SLE). Here we analyzed the phenotype of circulating DC from patients with SLE and studied their differentiation from monocytes. Peripheral blood DC exhibited increased levels of activation in patients with SLE. Although their in vitro differentiation process occurred normally, their responses to activation stimuli (LPS, TNF-α plus PGE(2), anti-CD40) were abnormal when compared to DC differentiated from healthy monocytes. When incubated in the presence of IL-10, DC from patients with SLE were able to induce tolerance to allogeneic antigens in a normal manner. Our results suggest that DC from patients with SLE are abnormal, in part due to the effect of abundant pro-inflammatory signals, but also because of intrinsic cellular defects that alter their responses to activation stimuli
