All NK cells divide in response to acute CMV infection. (A and B) CD56^dimCD16⁺ NK cells were gated on NKG2C⁺ and NKG2C⁻ cells, and Ki-67 expression on all CD56^dimCD16⁺ NK cells and in each subset was assessed. Graphs from representative SOT recipients with CMV viremia (A; n = 4) and without CMV viremia (B) are shown. Solid line and empty circle represent CD56^dimCD16⁺ NK cells, solid line and square represent NKG2C⁺ NK cells, and dashed line and triangle represent NKG2C⁻ NK cells. (C) The percentage of Ki-67⁺ cells within the CD56^dimCD16⁺ NK cells detected over time in healthy CMV⁺ donors is shown.
