Abstract

Immunological memory provides long-term protection against reinfection or reactivation of pathogens. Murine memory T cell populations may be compressed following infections with new pathogens. Humans have to retain memory T cells directed against a variety of microbes for many decades. Under these circumstances, the effect of pathogens that mount robust T cell reactivity on the pre-existing memory directed against unrelated microbes is unknown. In this study, we studied peripheral blood memory CD8+ T cells directed against different viruses following primary CMV infection in renal transplant recipients. The entrance of CMV-specific CD8+ T cells expanded the Ag-primed CD8+ T cell compartment rather than competing for space with pre-existing memory T cells specific for persistent or cleared viruses. Neither numbers nor phenotype of EBV- or influenza-specific CD8+ T cells was altered by primary CMV infection. CMV-specific CD8+ T cells accumulated over time, resulting in increased total CD8+ T cell numbers. Additionally, they acquired a highly differentiated cytolytic phenotype that was clearly distinct from EBV- or influenza-reactive T cells. Thus, the human immune system appears to be flexible and is able to expand when encountering CMV. In view of the phenotypic differences between virus-specific T cells, this expansion may take place in cellular niches different from those occupied by EBV- or influenza-specific T cells, thereby preserving immunity to these pathogens.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
