In this study, rat neutrophils and macrophages produced cytokine-induced neutrophil chemoattractants (CINCs) and rat macrophage inflammatory protein-1α (MIP-lα) in different patterns during phagocytosis of heat-killed yeast cells in vitro. The cultured supernatants of the phagocytosing rat neutrophils and macrophages had chemotactic activities toward neutrophils, and the chemotactic potencies were markedly inhibited by anti-CINCs IgGs or/and anti-MIP-lα IgG, suggesting that CINCs and MIP-lα are major neutrophil chemoattractants produced by the phagocytosing neutrophils and macrophages. Dexamethasone suppressed the production of CINCs and MIP-1α by the phagocytosing cells in a dose-dependent manner. Our results demonstrate significant differences in the production of CINCs and MIP-1α by neutrophils and macrophages during phagocytosis of yeast cells and thus may suggest the different contribution of each chemokine to neutrophil recruitment in the processes of inflammation in rats.
