IL-1beta is a proinflammatory cytokine produced in a variety of cells including monocytes, tissue macrophages, keratinocytes and other epithelial cells. Both IL-1alpha and IL-1beta binds to the same receptor and has similar biological properties. These cytokines have a broad range of activities including, stimulation of thymocyte proliferation, B-cell maturation and proliferation, mitogenic FGF-like activity and stimulation of the release of prostaglandin and collagenase from synovial cells. However, whereas IL-1beta is a secreted cytokine, IL-1alpha is predominantly a cell-associated cytokine. Recombinant rat IL-1beta is a 17.4 kDa protein containing 153 amino acid residues.
