Interleukin-23A (IL-23A) is a key pro-inflammatory cytokine that belongs to the IL-12 cytokine family. It forms a heterodimeric complex with IL-12B (p40 subunit) to create the bioactive IL-23 cytokine (composed of p19 and p40 subunits). IL-23 is primarily produced by activated dendritic cells, macrophages, and monocytes. Its biological function is mediated through binding to a specific receptor complex, IL-23R, which pairs with IL-12Rβ1, expressed mainly on the surface of immune cells such as T helper 17 (Th17) cells, innate lymphoid cells, and macrophages.
The primary role of IL-23 is to stabilize and expand the Th17 cell lineage, which subsequently produces effector cytokines like IL-17A, IL-17F, and IL-22. This IL-23/Th17 axis is a central driver of chronic inflammation and autoimmune pathology. Consequently, dysregulated IL-23 signaling is strongly implicated in the pathogenesis of several immune-mediated inflammatory diseases, including psoriasis, psoriatic arthritis, inflammatory bowel disease (e.g., Crohn's disease), and ankylosing spondylitis. This critical involvement has made IL-23A and its receptor prime therapeutic targets, with several monoclonal antibodies achieving significant clinical success.
