KLRC2 and infection: Using RNA probes able to distinguish expression of the two genes by flow cytometry (36), as previously used to uncover higher fractions of NKG2C-expressing cells in RhCMVpos vs. RhCMVneg animals, we documented increase expression in CD16+ NK cells in the three animals we monitored before and after infection, further supporting the relevance of our model to NK dynamics in humans following RhCMV infection.
