CD57, CD300, and CD161 expression on CD8+ T-cells. (A) Total expression (percentage) of CD57, CD161, and CD300a markers on CD8+ T-cells from young CMV-seronegative (n = 22), young CMV-seropositive (n = 15), middle age CMV-seropositive (n = 13), and old CMV-seropositive donors (n = 14). (B) Co-expression of CD57, CD161, and CD300a on CD8+ T-cells. Graphs show the phenotype combinations CD8+ T-cells in which we found statistical differences among the four groups studied. Vertical blacklines indicate interquartile ranges, ranging from the 25th to the 75th percentile. The median values are indicated by a horizontal black line. Results were considered significant at *p < 0.05, **p < 0.01, and ***p < 0.001.
