ABSTRACT
Objective To investigate the effect of vitamin D (VD) on macrophage to phagocytize Staphylococcus aureus (SA). Method Macrophoge cell lines RAW264.7 were allocated into 3 groupscontrol group(C),bacterium group(B),active vitamin D+ bacterium group (VD+B). Cells in the VD+B group were incubated with 10-8mol/L active vitamin D for 24h,then cells in the VD+B group and the B group were cultured with SA for 1h,and phagocytosis rate,mitochondrial membrane potential,[Ca~(2+)]i,reactive oxygen species were determined by flow cytometry (FCM). Results The phagocytizing activity of macrophage in VD+B group was significantly higher than that in B group 1h after infection,At the same time,the mitochondrial member potential and [Ca~(2+)]i of macrophage in VD+B group were distinctly lower than that in B group; but reactive oxygen species of macrophage in the VD+B group was insignificantly different from B group. Conclusion Vitamin D can reinforce the phagocytizing activity of macrophage and inhibit the apoptosis of macrophage after phagocytize Staphylococrcus aureus.
