The impact of the gut microbiota on human health: an integrative view

Open access

Abstract

The human gut harbors diverse microbes that play a fundamental role in the well-being of their host. The constituents of the microbiota—bacteria, viruses, and eukaryotes—have been shown to interact with one another and with the host immune system in ways that influence the development of disease. We review these interactions and suggest that a holistic approach to studying the microbiota that goes beyond characterization of community composition and encompasses dynamic interactions between all components of the microbiota and host tissue over time will be crucial for building predictive models for diagnosis and treatment of diseases linked to imbalances in our microbiota.

  • The therapeutic effectiveness of ICIs depends on a healthy gut microbiota, which requires microbial diversity and dynamic equilibrium with the immune system.

    “The therapeutic effectiveness of ICIs depends on a healthy gut microbiota, which requires microbial diversity and dynamic equilibrium with the immune system135,136.”

    From Microbiome meets immunotherapy: unlocking the hidden predictors of immune checkpoint inhibitors (2025) · cites this paper as [136]

    The Introduction and ‘Interactions between the Host Immune System and the Microbiota’ sections describe the gut microbiota’s role in normal immune function; the paper also discusses microbial diversity, dynamic interactions, and dysbiosis. It does not address immune checkpoint inhibitors (ICIs) or establish that their therapeutic effectiveness depends on a healthy gut microbiota. Page numbers are unavailable in our copy.

  • Bifidobacterium and Lactobacillus spp. are more abundant in healthy states than in disease states.

    “Specific bacteria shown to be more abundant in health compared with disease states include Bifidobacterium and Lactobacillus spp.(2,7,14)”
  • Specific nutrients, especially protein and insoluble fiber, have profound effects on gut microbiota structure, function, and secretion of metabolites that modulate immune function and multiple metabolic and inflammatory pathways.

    “Accumulating metagenomic data show that specific nutrients, especially protein and insoluble fiber, have profound effects on gut microbiota structure, function, and secretion of metabolites that modulate immune function and multiple metabolic and inflammatory pathways (86–88).”
  • Altered composition and function of gut microbiota have been linked to a number of chronic diseases, including colon cancer, irritated bowel syndrome, colitis, obesity, and diabetes mellitus.

    “Altered composition and function of gut microbiota have been linked to a number of chronic diseases, including colon cancer, irritated bowel syndrome, colitis, obesity, and diabetes mellitus.3”
  • The gut bacteria of urban-industrialized populations often have high abundances of Bacteroides, while the gut bacteria from traditional hunter-gatherer or agropastoral societies have higher abundances of Prevotella.

    “The gut bacteria of urban-industrialized populations often have high abundances of Bacteroides, while the gut bacteria from traditional hunter-gatherer or agropastoral societies have higher abundances of Prevotella [22–28].”

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.
