Abstract

T cell exhaustion often occurs during chronic infection and prevents optimal viral control. The molecular pathways involved in T cell exhaustion remain poorly understood. Here we show that exhausted CD8+ T cells are subject to complex layers of negative regulation resulting from the coexpression of multiple inhibitory receptors. Exhausted CD8+ T cells expressed up to seven inhibitory receptors. Coexpression of multiple distinct inhibitory receptors was associated with greater T cell exhaustion and more severe infection. Regulation of T cell exhaustion by various inhibitory pathways was nonredundant, as blockade of the T cell inhibitory receptors PD-1 and LAG-3 simultaneously and synergistically improved T cell responses and diminished viral load in vivo. Thus, CD8+ T cell responses during chronic viral infections are regulated by complex patterns of coexpressed inhibitory receptors.

  • In persistent disease settings such as chronic infection and malignancies, T cells acquire multiple inhibitory surface molecules that effectively prevent T cell activation.

    “T cells acquiring multiple inhibitory surface molecules in persistent disease settings such as chronic infection [37,38] and malignancies [30,**39,40], which effectively prevent T cell activation.”
  • Tim-3, LAG-3, and BTLA are co-expressed with PD-1, and this co-expression strongly correlates with immune dysfunction in cancer patients.

    “In the course of defining exhausted PD-1+ T cells, T cell immunoglobulin and mucin-domain-containing molecule-3 (Tim-3) [39,41], lymphocyte-activation gene (LAG)-3 [38], and the B and T-cell lymphocyte attenuator (BTLA, CD272) [42,43] were found to be co-expressed with PD-1, and the co-expression has been strongly correlated with immune dysfunction in patients with cancer.”
  • Exhausted T cells may highly express multiple inhibitory receptors, including PD-1, 2B4, BTLA, CTLA-4, CD160, LAG-3, and Tim-3.

    “Notably, exhausted T cells may highly express multiple “inhibitory” receptors, including PD-1, 2B4 (CD244), BTLA, CTLA-4, CD160, LAG-3 and Tim-3 [38,42,43,45].”
  • T cells co-expressing these surface molecules show significant decrease in IL-2, IFNγ, and TNFα expression as well as cell cycle arrest, which defines T cell exhaustion.

    “In these studies, T cells co-expressing these surface molecules show a significant decrease in IL-2, IFNγ, and TNFα expression as well as cell cycle arrest, which defines T cell exhaustion.”
  • During chronic inflammation, T cells become exhausted and upregulate non-redundant inhibitory receptors such as PD-1, CTLA-4, TIM-3, LAG-3, and TIGIT that limit their effectiveness.

    “During chronic inflammation in particular, T cells are known to become exhausted and to upregulate a wide range of non-redundant inhibitory receptors that limit their effectiveness, such as PD-1, CTLA-4, T-cell immunoglobulin and mucin-domain containing-3 (TIM-3), lymphocyte-activation gene 3 (LAG-3), or T-Cell immunoreceptor with Ig And ITIM domains (TIGIT) [See Table 1 (9–11)].”

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.
