概要 The central mediators of the adaptive immune response are T cells. The clonal

expansion of T cells required for adaptive immunity results from the innate immune

response, which is triggered by the stimulation of toll-like receptors (TLRs). The

adaptive immune response can cause autoimmune diseases, and Th17 cells are known to

contribute to several autoimmune diseases. Pathogenic Th17 cells are induced by

interleukin 23 (IL-23) and IL-1β. Resiquimod (a TLR7/8 agonist) significantly enhances

IL-23 production by human macrophages, and lipopolysaccharide (a TLR4 agonist)

slightly enhances it. Interestingly, IL-23 levels are significantly attenuated after

sequential stimulation with lipopolysaccharide and resiquimod, indicating cross-talk

between the TLR4 and TLR7/8 signaling pathways. In this review, we discuss the

pivotal role of TLRs in triggering innate immunity and inducing adaptive immunity,

leading to autoimmune diseases.
