Thrombospondin and fibronectin are synthesized by neutrophils in human inflammatory joint disease and in a rabbit model of in vivo neutrophil activation.

Abstract

Using 35S-methionine metabolic labeling, we studied de novo synthesis and secretion of proteins by activated polymorphonuclear neutrophils (PMN) from two different sources. PMN isolated from inflammatory synovial fluid of patients with inflammatory joint disease were first analyzed. The protein synthetic activity of these cells was compared with that of… (More)
