Abstract

Cancer immunotherapies have shown sustained clinical responses in treating non-small-cell lung cancer 1-3, but efficacy varies and depends in part on the amount and properties of tumor infiltrating lymphocytes 4-6. To depict the baseline landscape of the composition, lineage and functional states of tumor infiltrating lymphocytes, here we performed deep single-cell RNA sequencing for 12,346 T cells from 14 treatment-naïve non-small-cell lung cancer patients. Combined expression and T cell antigen receptor based lineage tracking revealed a significant proportion of inter-tissue effector T cells with a highly migratory nature. As well as tumor-infiltrating CD8+ T cells undergoing exhaustion, we observed two clusters of cells exhibiting states preceding exhaustion, and a high ratio of "pre-exhausted" to exhausted T cells was associated with better prognosis of lung adenocarcinoma. Additionally, we observed further heterogeneity within the tumor regulatory T cells (Tregs), characterized by the bimodal distribution of TNFRSF9, an activation marker for antigen-specific Tregs. The gene signature of those activated tumor Tregs, which included IL1R2, correlated with poor prognosis in lung adenocarcinoma. Our study provides a new approach for patient stratification and will help further understand the functional states and dynamics of T cells in lung cancer.

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

  • The aTregs subset overexpressed Foxp3, Cd81, Cd74, and Cst7, together with aTregs-associated genes Tnfrsf4, Tnfrsf9, Tnfrsf18, and Ikzf2.

    “activated regulatory T cells (aTregs) overexpressing Foxp3, Cd81, Cd74, and Cst7 genes, together with aTregs-associated genes such as Tnfrsf4, Tnfrsf9, Tnfrsf18, and Ikzf2 (21, 29, 30)”
  • rTregs subset expressed higher levels of quiescence genes Ms4a4b and Sell, whereas aTregs subset expressed higher levels of coinhibitory Pdcd1 and Lag3, costimulatory Tnfrsf9 and Tnfrsf4, activation genes S100a11 and Il1r2, and TF Ikzf2.

    “whereas the rTregs subset expressed higher levels of quiescence genes (e.g., Ms4a4b and Sell), aTregs subset expressed higher levels of coinhibitory (e.g., Pdcd1 and Lag3) and costimulatory genes [e.g., Tnfrsf9 and Tnfrsf4; (38)], activation genes [S100a11 and Il1r2 (IL1 decoy receptor); (39)], and the transcription factor (TF) Ikzf2 (30).”
  • Both aTregs and exhausted cells have been directly implicated in the tumor microenvironment as cells that can suppress tumor immunity, and thus a decline in T cell effector functions along with chronic inflammation and increased frequencies of RECs may play a key role in age-related onset of cancer.

    “For example, both aTregs and exhausted cells have been directly implicated in the tumor microenvironment as cells that can suppress tumor immunity (29, 30), and thus a decline in T cell effector functions along with chronic inflammation and increased frequencies of RECs may play a key role in age-related onset of cancer.”

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.
