  • Polymorphonuclear cells (PMNs) contribute to the initiation and progression of the immune response by mediating cytotoxicity, phagocytosis, and cytokine secretion. Because CD44 serves as a cytotoxic-triggering molecule on PMNs, it was hypothesized that it could also trigger cytokine production. In this study, the effect of anti-CD44 antibodies on interleukin-6 (IL-6) production in human PMNs was assessed. It was shown that PMNs stimulated with a mouse monoclonal or a rabbit polyclonal F(ab)(2) anti-CD44 transcribe IL-6 messenger RNA. A similar effect was obtained when an anti-CD44 antibody was replaced with hyaluronic acid (HA). Kinetic studies showed that anti-CD44 and HA induced IL-6 gene transcription, initiated 3 hours after stimulation, peaked between 12 and 24 hours, and disappeared after 48 hours. Analogous results were achieved when secreted IL-6 protein was measured by enzyme-linked immunosorbent assay in the PMN culture supernatants. To characterize which metabolic pathways regulated CD44-dependent IL-6 production in PMNs, an RNA polymerase inhibitor, actinomycin D, and 2 protein kinase inhibitors, such as genistein and staurosporine, were tested. Actinomycin D and genistein blocked IL-6 production, whereas staurosporine did not, suggesting that CD44-dependent IL-6 production requires gene transcription and tyrosine kinase activity. The relationship between CD44 and cytokines that affect PMN function, including interferon gamma (IFNgamma) and IL-2, was investigated. (literal)

Abstract
  • Polymorphonuclear cells (PMNs) contribute to the initiation and progression of the immune response by mediating cytotoxicity, phagocytosis, and cytokine secretion. Because CD44 serves as a cytotoxic-triggering molecule on PMNs, it was hypothesized that it could also trigger cytokine production. In this study, the effect of anti-CD44 antibodies on interleukin-6 (IL-6) production in human PMNs was assessed. By using a reverse transcriptase-polymerase chain reaction, it was shown that PMNs stimulated with a mouse monoclonal or a rabbit polyclonal F(ab)(2) anti-CD44 transcribe IL-6 messenger RNA. A similar effect was obtained when an anti-CD44 antibody was replaced with hyaluronic acid (HA). Kinetic studies showed that anti-CD44 and HA induced IL-6 gene transcription, initiated 3 hours after stimulation, peaked between 12 and 24 hours, and disappeared after 48 hours. Analogous results were achieved when secreted IL-6 protein was measured by enzyme-linked immunosorbent assay in the PMN culture supernatants. To characterize which metabolic pathways regulated CD44-dependent IL-6 production in PMNs, an RNA polymerase inhibitor, actinomycin D, and 2 protein kinase inhibitors, such as genistein and staurosporine, were tested. Actinomycin D and genistein blocked IL-6 production, whereas staurosporine did not, suggesting that CD44-dependent IL-6 production requires gene transcription and tyrosine kinase activity. Furthermore, the relationship between CD44 and cytokines that affect PMN function, including interferon gamma (IFNgamma) and IL-2, was investigated. Without CD44 cross-linking, IFNgamma did not trigger IL-6 production. However, on CD44 cross-linking, IFNgamma produced a strong synergistic effect on IL-6 syntheses in human PMNs.
