Abstract
Rat alveolar macrophages incubated with recombinant rat interferon-γ producel-arginine-dependent nitric oxide, which is rapidly decomposed into nitrite: this production by interferon-γ was markedly enhanced by granulocyte-macrophage colony-stimulating factor and muramyldipeptide, but not by other cytokines. The enhancement was dependent on the presence ofl-arginine in the incubation medium. It was based on a simple synergism between interferon-γ and muramyldipeptide and a priming effect of granulocyte-macrophage colony-stimulating factor for interferon-γ-induced nitrite production. These data suggest that cytokine networks are important in the induction of nitric oxide in rat alveolar macrophages.
