Summarizing phenotypic comparison of PB- and LN-derived CD8⁺ T cells. Representative dot plots of CMV-seronegative (n = 4 CD27/CD45RA and CCR7/CX3CR1, n = 2 granzyme B/K, top rows in each panel) and CMV-seropositive (n = 10 CD27/CD45RA and CCR7/CX3CR1, n = 9 granzyme B/K, bottom row in each panel) PB (top panel) and LN (bottom panel) CD8⁺ T cells analyzed for expression of CD27 and CD45RA, CCR7, CX3CR1, granzyme K, and granzyme B.
