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.\u003cbr\u003e\u003cbr\u003eThe 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.\u003c\/p\u003e\u003c\/div\u003e","brand":"UA BIOSCIENCE","offers":[{"title":"25μg","offer_id":42332763652171,"sku":null,"price":210.0,"currency_code":"USD","in_stock":true},{"title":"100μg","offer_id":42332763684939,"sku":null,"price":410.0,"currency_code":"USD","in_stock":true},{"title":"500μg","offer_id":42332763717707,"sku":null,"price":1145.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0590\/8375\/1499\/files\/AntBioImage_59857f6e-4950-471b-8193-5c283f62e747.png?v=1776073617","url":"https:\/\/www.antbioinc.com\/products\/il-23a20-189-fc-chimera-protein-human-ua011357","provider":"AntBio","version":"1.0","type":"link"}
