Interleukin-23 (IL-23) is a cytokine that plays a crucial role in the inflammatory response and immune system regulation. It is part of the IL-12 family and is primarily produced by activated dendritic cells, macrophages, and monocytes. IL-23 is known to promote the differentiation and proliferation of T-helper 17 (Th17) cells, which are implicated in various autoimmune and inflammatory disorders.
