"NK-cell function is regulated by a balance between inhibitory and activating killer cell immunoglobulin-like receptors (KIR) that specifically recognize HLA class I molecules. Using KIR-specific mAb to discriminate between KIR2DS1 and KIR2DL1 receptors, we show that KIR2DS1(+) NK cells are C2-alloreactive only from C2(-) individuals," researchers in France report (see also Immunology).
"Moreover, using an in vitro model of NK-cell expansion, we show here that the frequency of KIR2DL1(+) NK cells is significantly higher in the absence of C2 ligand on stimulator EBV-B cells than in its presence. This observation was made regardless of the presence or absence of ...
