NKG2C⁺CD57⁺ Natural Killer Cell Expansion Parallels Cytomegalovirus-Specific CD8⁺ T Cell Evolution towards Senescence

Figure 1

Distribution of CD57⁺NKG2C⁺ NK frequencies in different groups. Flow cytometry was done on PBMC to assess CD57⁺NKG2C⁺ NK frequency by gating on lymphocytes, excluding CD3⁺ cells, gating on cells, and plotting NKG2C versus CD57 expression. Horizontal lines bisecting groups represent medians with IQR shown above and below them. Significant differences between medians are shown above lines spanning the groups compared.
