KLRC2 and cytomegalovirus infection: We analyzed seven different individuals with an NKG2C+ population and having at least one copy of HLA-C2 and co-inheriting both KIR2DL1-C245 and KIR2DL1-R245 allotypes to determine whether higher education and stronger “missing self” reactivity was preferentially associated with expansion of NKG2C after HCMV infection (Figure 7A).
