Abstract

When hepatitis B virus (HBV)-specific CD8(+) cytotoxic T lymphocytes (CTLs) are adoptively transferred into HBV transgenic mice, they enter the liver, recognize antigen, secrete interferon gamma (IFNgamma), inhibit viral replication, and kill their target cells, causing hepatitis. In the current study, we examined the impact of antigen recognition on the evolution of the activation phenotype, antiviral effector functions, expansion and contraction kinetics, and compartmentalization of the transferred CTLs. The results reveal that noncytolytic and cytolytic effector functions and expansion-contraction kinetics of the CTLs are regulated asynchronously and in an oscillatory manner as a consequence of antigen recognition in the liver and in association with PD-1 upregulation. We suggest that such oscillations maximize viral clearance and minimize tissue injury during HBV infection and that poor coordination of these events could lead to viral persistence and chronic liver disease.

Recomputing p-values needs the paper’s full text.

Claims the paper makes

We couldn’t retrieve this paper’s full text, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Following presentation of viral antigens coupled to MHC class I molecules by infected hepatocytes, virus-specific CTLs clear hepatitis viruses by both cytolytic and non-cytolytic effector functions.

    “Following presentation of viral antigens coupled to MHC class I molecules by infected hepatocytes, virus-specific CTLs are able to clear hepatitis viruses by means of both cytolytic and non-cytolytic effector functions (182-184).”

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.
