Potent proinflammatory cytokine. Initially discovered as the major endogenous pyrogen, induces prostaglandin synthesis, neutrophil influx and activation, T-cell activation and cytokine production, B-cell activation and antibody production, and fibroblast proliferation and collagen production. Promotes Th17 differentiation of T-cells. Synergizes with IL12/interleukin-12 to induce IFNG synthesis from T-helper 1 (Th1) cells.
Interleukin-1 beta (IL-1 beta), is an E. coli-derived recombinant protein corresponding to full-length mature rat interleukin 1 beta (IL-1b), an immunomodulary cytokine that mediates a wide range of immune responses.
Source:Recombinant protein corresponding to rat Interleukin-1 beta expressed in E. coli.
