Dexamethasone-mediated inhibition of human T cell growth factor and gamma-interferon messenger RNA.

Abstract

Glucocorticoids suppress the proliferation of human T lymphocytes. Activated T lymphocytes require T cell growth factor (TCGF) for proliferation. TCGF is produced by a subset of T lymphocytes, and this production is regulated at the TCGF mRNA level. Dexamethasone, a synthetic glucocorticoid, strongly inhibits the synthesis of TCGF mRNA in human normal peripheral blood lymphocytes stimulated in culture with phytohemagglutinin. It also inhibits the accumulation of gamma-interferon mRNA in these cells. This dual effect may in part explain some of the immunosuppressive and anti-inflammatory effects of glucocorticoids.
