Interleukin-1 (IL-1) describes two inflammatory proteins1, IL-1α and IL-1β, produced by activated macrophages and other cell types2 and encoded by two genes. Their amino acid sequences have only 26% similarity1, but their biological activities are comparable, with a few exceptions3,4; indeed, both molecules appear to act at the same receptor5,6. As IL-1 releases prostaglandins7 which sensitize nociceptors in man and in experimental animals8, we tested IL-1α and IL-1β in rats for hyperalgesic…

Using specific antisera and COX inhibitors it is demonstrated that interleukin-lβ (IL-1β) is a key cytokine for the release of prostaglandins (PG) and induction of COX-2 is a limiting process in the development of inflammatory hyperalgesia.

It is demonstrated that methylated BSA (mBSA) induced hypernociception via the IL-33 → TNFα → IL-1β → IFNγ → ET-1 → PGE2 signaling cascade, revealing a hitherto unrecognized function of IL- 33 in a key immune pharmacological pathway that may be amenable to therapeutic intervention.

Human interleukin-1beta domain in position 163-171, comprising the amino acids VQGEESNDK, has been synthesized as a nine-amino-acid-long peptide and used in vivo as a nontoxic HCl salt, and the DNA sequence encoding the IL-1 beta domain has been included in an experimental DNA vaccine with positive results.

It is shown here that the receptor for IL-1α on both murine and human cells is identical to that forIL-1β, which raises the issue of what separation, if any, there might be between the biological activities of IL- 1α and IL-2β.
