title: Species restrictions demonstrated by the stimulation of equine cells with recombinant human interleukin-1.
abstract: Equine thymocytes, which respond to equine monocyte supernatants, do not respond to stimulation with recombinant human interleukin-1 alpha and beta, and equine synovial fibroblasts show a limited response in the form of prostaglandin E2 production without any evidence of neutral metalloproteinase production. Human interleukin-1 beta was about three to ten times as active on equine synovial cells as human interleukin-1 alpha in terms of prostaglandin E2 production. This preliminary evidence would suggest that there are qualitative and quantitative differences in the way recombinant human interleukin-1 stimulates human cells and the way in which it stimulates equine cells.
