Enhanced phagocytosis through inhibition of de novo ceramide synthesis.


Fcgamma receptors are important mediators of the binding of IgG to and induction of phagocytosis in neutrophils. COS-1 cells provide a potentially useful model for studying these receptors because transfection with the FcgammaRIIA renders these cells phagocytic. During FcgammaRIIA-mediated phagocytosis in COS-1 cells, endogenous ceramide levels increased 52… (More)
