The control of B7-H6 is likely to be of major significance as NKp30 is expressed on γδ T-cells (Vδ2-) that are induced during HCMV infection post-transplantation and correlate with control of disease (Merville et al., 2000; Lafarge et al., 2001; Correia et al., 2011). Here, NCR3 is linked to cytomegalovirus infection.
