Abstract excerpt
Natural killer (NK) cells are cytotoxic innate lymphoid cells that are involved in immune defense. NK cell reactivity is controlled in part by MHC class I recognition by inhibitory receptors, but the underlying molecular mechanisms remain undefined. Using a mouse model of conditional deletion in NK cells, we show here that the protein tyrosine phosphatase SHP-1 is essential for the inhibitory function of NK cell...
