Background: IL-23

IL-23 p19 (Interleukin 23 p19; also IL-23 alpha) is an 18-20 kDa (estimated) member of the IL-6 superfamily of molecules. It is disulfide-bonded to p40 to form IL-23. IL-23 is secreted by immune-related cell types such as keratinocytes, dendritic cells, macrophages, microglia and monocytes, often following TLR stimulation. It appears to drive Th17 cell development by inhibiting T-bet and FoxP3 production, and to reduce IL-12-mediated IFN-gamma production by CD4⁺, CD8⁺ and NK cells. Based on human, mature canine IL-23 p19 is 171 amino acids (aa) in length. It is a alpha -helical molecule that utilizes Cys77 to form an interchain disulfide bond with IL-12 p40. IL-23 p19 does not appear to be released unless dimerized to p40. There are no potential N-linked glycosylation sites on p19. Mature canine IL-23 p19 (aa 23-193) shares 88% aa identity with human IL-23 p19.
