  • 產(chǎn)品描述：

    The gene fragment corresponding to the 117-269aa of the human IL1B protein was synthesized, with appropriate restriction sites suitable for in-frame cloning into an expression vector, with N-terminal 6xHis-SUMO tag. The E.coli was transformed with the expression vector, and the clone was expressed upon certain induction. After the induced cell centrifugation, the recombinant protein was purified from the cell extract and presented as N-terminal 6xHis-SUMO-tagged fusion. Its purity is greater than 90% assayed by SDS-PAGE. The IL1B protein ran to a band of about 33 kDa molecular weight on the gel.

    Interleukin 1beta is a proinflammatory cytokine encoded by the IL1B gene located on chromosome 2. Interleukin levels are normally low in the CNS but are elevated after acute injury and in chronic neurodegenerative diseases such as Alzheimer's disease (AD). IL1 gene variants should be considered disease modifiers in RA. Some researches found that he rare allele of the IL-1B is associated with the destructive pattern characteristic of chronic RA. The pro-inflammatory cytokine IL-1 is produced by the inflammatory synovium and appears to play a predominant role in the destructive pattern associated with RA. It is a known activator of collagenase and stromelysin and inhibits the synthesis of collagen and proteoglycan. In addition, p62-induced autophagic degradation of caspase-1 accounted for caspase-1/IL1B inactivation in CD44s deficient cells. Many findings implied that IL1B polymorphisms modulate cystic fibrosis lung disease.

  • 功能：
    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. Plays a role in angiogenesis by inducing VEGF production synergistically with TNF and IL6.
