Reduced in vitro expansion of CMV-specific CD8⁺ T_CM cells compared to IAV-specific CD8⁺ T_CM cells. A Experimental design for the expansion of CMV- and IAV-specific CD8⁺ T cells by artificial antigen presenting cell (aAPC) in vitro. B-D Expansion of CMV- and IAV- specific CD8⁺ T cells (Total, T_N, and T_CM) from the same CMV IgG positive healthy adults (N=10). * Indicates P < 0.05, ** indicates P < 0.01
