Additionally, KIR2DS2+ NK cells appear to have a greater potential to mediate antibody-dependent cellular cytotoxicity (ADCC) in vitro and in vivo.32 33 Furthermore, as killing of the B16 melanoma cell line is mediated by the activating NK cell receptor NKp46, KIR2DS2-independent anti-tumor responses are also generated. Here, NCR1 is linked to melanoma.
