Abstract

Cross-presentation of soluble Ag on MHC class I molecules to naive CD8 T cells by liver sinusoidal endothelial cells (LSECs) leads to induction of T cell tolerance that requires interaction between coinhibitory B7-H1 on LSECs and programmed cell death-1 on CD8 T cells. In this study, we investigate whether cross-presentation of high as well as low Ag concentrations allowed for LSEC-induced tolerance. Ag concentration directly correlated with the cross-presentation capacity of murine LSECs and thus strength of TCR stimulation. Although LSEC cross-presentation at low-Ag concentrations resulted in tolerance, they induced differentiation into effector T cells (CTL) at high-Ag concentrations. CTL differentiation under these conditions was not caused by increased expression of costimulatory CD80/86 on cross-presenting LSECs but was determined by early IL-2 release from naive CD8 T cells. B7-H1 signals from LSECs and TCR avidity reciprocally controlled early T cell release of IL-2 and CTL differentiation. B7-H1 expression directly correlated with cross-presentation at low- but not high-Ag concentrations, indicating an imbalance between TCR and coinhibitory signals regulating T cell release of IL-2. Exogenous IL-2 overrode coinhibitory B7-H1–mediated signals by LSECs and induced full CTL differentiation. Our results imply that LSEC-mediated T cell tolerance can be broken in situations where T cells bearing high-avidity TCR encounter LSECs cross-presenting high numbers of cognate MHC class I peptide molecules, such as during viral infection of the liver. Furthermore, we attribute a novel costimulatory function to IL-2 acting in a T cell autonomous fashion to promote local induction of immunity in the liver even in the absence of CD80/86 costimulation.

  • Hepatic infiltration by CD4+ T, CD8+ T and B lymphocytes is evident in different experimental models of MASH.

    “Hepatic infiltration by CD4+ T, CD8+ T and B lymphocytes is evident in different experimental models of MASH (28-30), while Rag1 -/mice which lack mature T and B cells are protected from lobular inflammation and liver cell injury induced by feeding a cholinedeficient high fat diet (28).”

    The Abstract and Discussion address CD8 T-cell responses to antigen presentation by liver sinusoidal endothelial cells, not lymphocyte infiltration in experimental MASH. Searches for MASH, steatohepatitis, B-cell infiltration, and choline-deficient high-fat diet found no passage addressing the attributed claim. Page numbers were not available in our copy.

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.
