Neutralizing monoclonal antibody against human IL-1β

Anti-hIL-1β-IgG (clone 4H5) is a monoclonal antibody (mAb) specific for human interleukin 1 beta (hIL-1β). It is produced in hybridomas and purified by affinity chromatography. This antibody has been selected for its ability to efficiently neutralize the biological activity of hIL-1β.
IL-1β is a soluble pro-inflammatory cytokine that plays a critical role in the host response to infection and injury [1].

Details

Interleukin-1 beta (IL-1β) is a secreted pro-inflammatory cytokine [1]. It participates in the generation of systemic and local responses to infection and injury [2]. IL-1β is produced by activated macrophages as a pro‑protein, which is cleaved by caspase 1, an enzyme that is activated within the inflammasome multiprotein complex [3].
The resulting mature IL-1β is secreted and binds to the IL-1RI receptor triggering the formation of the IL-1R1/IL-1R3/MyD88 complex and inducing MyD88‑mediated intracellular signaling. This leads to the activation of the transcription factor NK-κB signaling, and the JNK and p38 mitogen‑activated protein kinase pathways, which induce the expression of inflammatory cytokines and chemokines, such as IL-6 and IL-8 [4].
