IL-1 alpha

P01583

IL-1a is a non-secreted proinflammatory cytokine produced in a variety of cells including monocytes, tissue macrophages, keratinocytes and other epithelial cells. Both IL-1a and IL-1ß binds to the same receptor and has similar if not identical biological properties. These cytokines have a broad range of activities including, stimulation of thymocyte proliferation, by inducing IL-2 release, B-cell maturation and proliferation, mitogenic FGF-like activity and the ability to stimulate the release of prostaglandin and collagenase from synovial cells. However, whereas IL-1ß is a secreted cytokine, IL-1a is predominantly a cell-associated cytokine. Recombinant human IL-1a is an 18.0 kDa protein containing 159 amino acid residues.
