背景 | IL-1β is a pro-inflammatory cytokine produced predominantly by activated monocytes and epithelial cells (1). Precursor IL-1β is cleaved by caspase-1 and mature IL-1β is then secreted (1-3). Target cells include macrophages and many other cell types. Signaling by IL-1β involves IL-1β binding to IL-1 accessory protein (IL-1-AcP) and then the complex binds to IL-1RI (1,2). Signaling is through activation of MAP kinase and NF-κB pathways (1,2). IL-1β also binds to IL-1RII that lacks an intracellular signaling domain and thereby serves as a high affinity decoy receptor. IL-1β binding to IL-1RI is inhibited by the negative regulator, IL-1R antagonist (IL-1Ra). IL-1Ra binding to IL-1RI does not signal and serves to block IL-1β signaling. IL-1β plays critical roles in the acute phase response and sepsis (1-3). |

The production of IL-8 by primary human fibroblasts cultured with increasing concentrations of human IL-1β was assessed. Media from cells incubated with IL-1β for 24 hours was collected and assayed for IL-8 by ELISA and the OD450-OD650 was determined.用递增浓度的hIL-1β孵育诱导人成纤维原代细胞产生IL-8实验。用hIL-1β培养细胞24小时并收集上清,人IL-8用ELISA 实验测定,并测定OD450-OD650 数值。 | |
