Abstract

[Extract] Epstein-Barr virus (EBV) establishes a latent, life-long infection in more than 95% of the human adult population. Antigen-specific, cytolytic T lymphocytes (CTLs) are thought to be of central importance in controlling EBV in both primary and latent infection states. While a good deal is known about the CTL dynamics during primary infection and convalescence, little is known about the CTL repertoire during the decades of infection after first contact. For example, do CTL clones persist indefinitely throughout an individual's lifetime or do new naive T-cell expansions emerge to help refresh the repertoire? We addressed this question by investigating the CTL dynamics toward immunodominant EBV epitopes up to 18 years apart, which is, to our knowledge, the longest follow-up study of T-cell responses conducted in humans.
