Invitrogen™ eBioscience™ Mouse IL-23 ELISA Ready-SET-Go!™ Kit, 2nd Generation

Description

IL-23 is a heterodimeric cytokine composed of the p40 subunit of IL-12 that is disulfide-linked with to two subunits, a p19 subunit unique to IL-23, and a p40 subunit that is shared with IL-12. IL-23 interacts with IL-12Rbeta1 and a beta2-like receptor subunit with STAT4 binding domain, IL-23R. IL-23 is secreted by activated mouse and human dendritic cells and is involved in the inflammation process and associated with autoimmune diseases. Mouse IL-23 was found not to induce significant amounts of IFN-gamma, induces strong proliferation of memory T cells (but not naive T cells), and activate mouse memory T cells to produce the proinflammatory cytokine IL-17. On the other hand, human IL-23 induces proliferation of memory T cells, induces moderate levels of IFN-gamma, and is produced by naive and memory T cells. IL-23 plays an important role in stimulating memory T-cells, and is required for the induction, expansion, maintenance, and downstream effector functions of Th17 cells, which play a vital role in upregulating neutrophil chemokines and various pro-inflammatory cytokines. IL-23 interacts with the receptors IL-12R beta1 and IL-23R to activate the Jak-Stat signaling cascade. IL-23 has been shown to possess potent anti-tumor and anti-metastatic activity in mouse models of cancer, suggesting a potential role for IL-23 in therapeutic treatment of cancer.
