We found a similar frequency of eNK cell subtypes and cytokine levels with HHV-6A negative infertile women and controls (Table 4), while HHV-6A positive infertile women presented lower CD56bright and CD56dim eNK cell number, higher IL-10 and lower IFN-gamma levels in uterine flushing samples (Table 4). The gene discussed is IFNG; the disease is Infertility.
