BD Pharmingen™ Purified NA/LE Rat Anti-Mouse IL-23 p19

The N71-1183 monoclonal antibody specifically recognizes the alpha subunit, also known as p19, of mouse interleukin 23 that is encoded by the Il23a gene. Interleukin 23 (IL-23) is a heterodimeric cytokine composed of a p40 subunit and a p19 subunit. The p19 subunit is unique to IL-23, while the p40 subunit is shared with IL-12 and is also known as IL-12B.  Human and mouse p19 share 70% amino acid sequence identity. Dendritic cells and macrophages produce IL-23 in response to TLR2, TLR4 and TLR8 ligands, as well as the β-glucan receptor, Dectin-1. IL-23 has biological activities that are similar to, but distinct from IL-12: Both IL12 and IL-23 induce proliferation and IFN-γ production by human T cells. While IL-12 acts on both naïve and memory human T cells, the effects of IL-23 are restricted to memory T cells. IL-23, but not IL-12, has been shown to induce memory T cells to secret IL-17, a potent proinflammatory cytokine. In vitro and in vivo treatment with N71-1183 monoclonal antibody has been shown to inhibit IL-23's ability to enhance IL-17 production by activated MRL/lpr T lymphocytes (Kyttaris VC, Kampagianni O, Tsokos GC, 2013).
