Abstract

Human cytomegalovirus (CMV) establishes persistent, usually asymptomatic, infection in healthy people. Because CMV infection is associated with the presence of lower proportions of peripheral naïve CD8 + T-cells and a higher fraction of late-differentiated CD8 + cells, commonly taken as biomarkers of age-associated compromised adaptive immunity ('immunosenescence'), we asked whether chronic exposure to any persistent virus mediates these effects. Herpes simplex virus (HSV) is also a widespread herpesvirus that establishes lifelong persistence, but, unlike CMV, its impact on the distribution of T-cell subsets has not been established. Here, we analysed T-cell subsets in 93 healthy people aged 42-81 years infected or not infected with CMV and/or HSV. Individuals harbouring CMV were confirmed to possess lower frequencies of nai{dotless}̈ve CD8 + T-cells (defined as CD45RA +CCR7 +CD27 +CD28 +) and greater proportions of late-differentiated effector memory (CD45RA-CCR7-CD27-CD28-) and so-called TEMRA (CD45RA +CCR7 -CD27 -CD28 -) CD4 and CD8 subsets, independent of HSV seropositivity. In CMV -seronegative donors, HSV did not affect T-cell subset distribution significantly. We conclude that these hallmarks of age-associated alterations to immune signatures are indeed observed in the general population in people infected with CMV and not those infected with a different persistent herpesvirus.
