Abstract excerpt
NK cells can kill antibody-coated target cells following engagement of FcgammaRIIIA, the major activating FcgammaR expressed by these cells. The presence of FcgammaRIIC (CD32C) has also been reported, but its contribution to the FcgammaR-dependent effector functions of NK cells remains debated. We demonstrate here that inhibitory FcgammaRIIB is also expressed by a small subset of CD56+/NKp46+ NK cells and can...
