Abstract excerpt
Natural killer (NK) cells express inhibitory receptors for major histocompatibility complex (MHC) class I. If self-MHC is down-regulated or absent, lack of inhibition triggers "missing self" killing. NK cells developing in the absence of MHC class I are hypo-responsive, demonstrating that MHC class I molecules are required for NK-cell education. Here, we show that the number and the type of MHC class I alleles...
