Despite general acceptance that immunologic changes are associated with aging and latent
infection with Cytomegalovirus (CMV), no clear-cut distinction has so far been made
between strictly age-related and CMV-induced changes. We therefore compared CD4+ and
CD8+ naïve (CD45RA+ CD28+), memory (CD45RA− CD28+), and effector (CD28−) T cells
in CMV-positive (n= 164) and CMV-negative (n= 87) elderly persons and correlated CD8+
and CD4+ effector T cells with other T-cell subpopulations. Percentages of CD8+ as well as …
