IL-23 p19 Monoclonal Antibody (HNU2319), Functional Grade, eBioscience™, Invitrogen™

Description

The HNU2319 MAb is specific to the p19 subunit of human IL-23, a heterodimeric cytokine made up of two covalently linked subunits, p40 and p19. It is closely related to IL-12, with which it shares the p40 subunit. Dendritic cells and macrophages produce IL-23 in response to TLR2, TLR4, and TLR8 ligands, as well as the beta-glucan receptor Dectin-1. Human IL-23 induces proliferation of memory T cells and induces moderate levels of IFN-gamma production by naive and memory T cells, as compared to IL-12. In contrast, the mouse IL-23 biological activities are more distinctly different than those of mouse IL-12 suggesting the signaling or response elements (receptors) differ between species. The IL-23 receptor is also heterodimeric and shares the IL-12Rbeta1 chain with IL-12, while the IL-23R chain is unique to IL-23. Signaling occurs through the Jak/STAT pathway and results in RORgammat expression, which drives the differentiation of CD4^+ T-cells towards the Th17 phenotype. The MAb HNU2319 neutralizes the bioactivity of IL-23 without affecting IL-12.
