Receptors for the fragment crystallizable region of immunoglobulin-G (FcgammaRs) play an important role in linking the humoral and cellular arms of the immune response. In this study, we present a comprehensive functional comparison of 2 human Fc-receptors, FcgammaRI and FcgammaRIIa. Activation of FcgammaRI results in a novel signaling cascade that links phospholipase D1 to sphingosine kinase-1 in U937 cells and primary human monocytes. This induces the expression of proinflammatory mediators an ...[more]
