Background
IL-2 Human interleukin-2 (IL-2) has several roles in the immune system, immune tolerance and immunity against pathogens, primarily by its direct effects on T lymphocytes. In general, depending on the context, IL-2 can function to initiate or dampen immune responses. IL-2 promotes the differentiation of immature T lymphocytes into regulatory T cells, which help protect against autoimmunity. In the presence of stimulated antigen, IL-2 drives T cell differentiation into effector T cells and later into memory T cells that function to fight off infections. Also, IL-2 promotes T cell differentiation into Th1 and Th2 lymphocytes while inhibiting Th17 differentiation. Elevated IL-2 levels have been reported in the saliva of patients with burning mouth syndrome and associated with severity of the illness (1).
