Mouse IL-23 Antibody Summary

Species Reactivity

Mouse

Specificity

Detects mouse IL-23 in ELISAs and Western blots. This antibody recognizes an epitope in the p19 subunit. In ELISAs, this antibody does not cross‑react with recombinant mouse (rm) IL-23 R, rmIL-12 R beta, rmIL-12 p35, recombinant human (rh) IL-23, rhIL-23 p19, recombinant rat IL-12, rmIL-12 p40, rmIL-12 p40 homodimer, or rmIL-12.

Background: IL-23

Interleukin 23 (IL-23) is a heterodimeric cytokine composed of two disulfide-linked subunits, a p19 subunit that is unique to IL-23, and a p40 subunit that is shared with IL-12 (1-5). The p19 subunit has homology to the p35 subunit of IL-12, as well as to other single chain cytokines such as IL-6 and IL-11. The p40 subunit is homologous to the extracellular domains of the hematopoietic cytokine receptors. Mouse p19 cDNA encodes a 196 amino acid residue (aa) precursor protein with a putative 19 aa signal peptide and 177 aa mature protein. Human and mouse p19 share 70% aa sequence identity. Although p19 is expressed by activated macrophages, dendritic cells, T cells, and endothelial cells, only activated macrophages and dendritic cells express p40 concurrently to produce IL-23. The functional IL-23 receptor complex consists of two receptor subunits, the IL-12 receptor beta 1 subunit (IL-12 R beta 1) and the IL-23-specific receptor subunit (IL-23 R). IL-23 has biological activities that are similar to, but distinct from IL-12. Both IL-12 and IL-23 induce proliferation and IFN-gamma production by human T cells. While IL-12 acts on both naïve and memory human T cells, the effects of IL-23 is restricted to memory T cells. In mouse, IL-23 but not IL-12, has also been shown to induce memory T cells to secret IL-17, a potent pro-inflammatory cytokine. IL-12 and IL-23 can induce IL-12 production from mouse splenic DC of both the CD8^- and CD8⁺ subtypes, however only IL-23 can act directly on CD8⁺ DC to mediate immunogenic presentation of poorly immunogenic tumor/self peptide.
