CD8A and infection: The viral dissemination (in co-culture assays with PBMC, NK cells, CD4+ and CD8+ T cells) and antibody neutralization results of the individual older donor cohort are shown with the range of the young donor (better viral control) and the seronegative donors (decreased viral control) indicated with the AQU007 and AQU022 responses superimposed on these charts for both phases of infection (Figures 7C, D).
