Biological activity

IL-1β is mainly secreted by monocytes and macrophages. IL-1β secretion has also been reported for a variety of other cells, including B cells, NK cells, dendritic cells, astrocytes, and microglial cells. IL-1β acts also on nonimmune system cells such as fibroblasts, vascular endothelial cells, and hepatocytes.

MACS GMP Recombinant Human IL-1β can be used for a variety of applications, including the ex vivo generation of human dendritic cells from enriched CD14⁺ monocyte populations.^2–4
