IL10 and autoimmune disease: A immunomodulatory cytokine, interleukin-10 (IL10), has potent anti-inflammatory and immunomodulating properties that play critical roles in limiting the immune response and preventing autoimmune disorders [17–19] IL10 is produced by various immune cells and inhibits macrophages, natural killer, Th1, and dendritic cell function [20] IL10 also inhibits production of pro-inflammatory cytokines and co-stimulatory molecules, and interferes with general antigen presenting cell function [17, 20, 21].
