Abstract

Immune checkpoint inhibitors (ICIs) therapy is a novel strategy for cancer treatments in recent years. However, it was observed that most patients treated with ICIs could not get benefit from the therapy, which led to the limitation of clinical application. Motivated by potent and durable efficacy of ICIs, oncologists endeavor to explore the mechanisms of resistance to ICIs and increase the drug sensitivity. It is known that heterogeneity of gut microbiome in populations may result in different outcomes of therapy. In xenograft model, bacteria in gut have been proved as a crucial factor regulating immunotherapy efficacy. And the similar phenomenon was obtained in patients. In this review, we summarized relevant advancements about gut microbiome and ICIs. Furthermore, we focused on modulatory function of gut microbiome in ICIs therapy and possible antitumor mechanism of specific commensals in ICIs treatment. We propose that gut microbiome is an important predictive factor, and manipulation of gut microbiome is feasible to elevate response rate in ICIs therapy.

  • Metabolic byproducts of gut microbiota are perceived by cells and molecules of the immune system and modulate the equilibrium between pro- and antitumor functions.

    “In conclusion, in view of the metabolic function elicited by gut microbiota, we infer that their metabolic byproducts are perceived by cells and molecules of the immune system and modulate the equilibrium between pro- and antitumor functions.”
  • Some gut bacteria act as suppressors of inhibitory signal pathways, facilitate antigen presentation, and improve specific antitumor immunity.

    “Some gut bacteria act as suppressors of inhibitory signal pathways, facilitate antigen presentation, and improve specific antitumor immunity (118).”
  • The influence of gut microbiota on host immunity is multifaceted, simultaneously regulating the gut mucosal immune system and the systemic immune system.

    “The influence of gut microbiota on host immunity is multifaceted, simultaneously regulating the gut mucosal immune system and systemic immune system (Fig. 2d) [307–310].”

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.
