C-reactive protein binding to FcgammaRIIa on human monocytes and neutrophils is allele-specific.

Abstract excerpt

C-reactive protein (CRP) is involved in host defense, regulation of inflammation, and modulation of autoimmune disease. Although the presence of receptors for CRP on phagocytes has been inferred for years, their identity was determined only recently. FcgammaRIa, the high-affinity IgG receptor, binds CRP with low affinity, whereas FcgammaRIIa, the low-affinity IgG receptor, binds CRP with high affinity. Because...
