Abstract

Human cytomegalovirus (HCMV) infections of immunocompetent hosts are characterized by a dynamic, life-long interaction in which host immune responses, particularly of T cells, restrain viral replication and prevent disease but do not eliminate the virus or preclude transmission. Because HCMV is among the largest and most complex of known viruses, the T cell resources committed to maintaining this balance have never been characterized completely. Here, using cytokine flow cytometry and 13,687 overlapping 15mer peptides comprising 213 HCMV open reading frames (ORFs), we found that 151 HCMV ORFs were immunogenic for CD4+ and/or CD8+ T cells, and that ORF immunogenicity was influenced only modestly by ORF expression kinetics and function. We further documented that total HCMV-specific T cell responses in seropositive subjects were enormous, comprising on average ∼10% of both the CD4+ and CD8+ memory compartments in blood, whereas cross-reactive recognition of HCMV proteins in seronegative individuals was limited to CD8+ T cells and was rare. These data provide the first glimpse of the total human T cell response to a complex infectious agent and will provide insight into the rules governing immunodominance and cross-reactivity in complex viral infections of humans.

  • Infection with CMV causes a large accumulation of virus-specific memory T cells, so that approximately 10% of the CD4+ and CD8+ T cell pool becomes specific for this virus.

    “Infection with CMV causes a large accumulation of virus-specific memory T cells, so that approximately 10 % of the CD4+ and CD8+ T cell pool becomes specific for this virus (Sylwester et al. 2005).”

  • It is currently unknown whether values such as 10% of the CD4+ and CD8+ T cell pool being specific for CMV is above, or below, the ideal threshold.

    “It is therefore currently unknown whether values such as 10 % of the CD4+ and CD8+ T cell pool being specific for CMV is above, or below, the ideal threshold (Sylwester et al. 2005).”

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.
