Role of the microbiota in immunity and inflammation.

Abstract

The microbiota plays a fundamental role on the induction, training, and function of the host immune system. In return, the immune system has largely evolved as a means to maintain the symbiotic relationship of the host with these highly diverse and evolving microbes. When operating optimally, this immune system-microbiota alliance allows the induction of protective responses to pathogens and the maintenance of regulatory pathways involved in the maintenance of tolerance to innocuous antigens. However, in high-income countries, overuse of antibiotics, changes in diet, and elimination of constitutive partners, such as nematodes, may have selected for a microbiota that lack the resilience and diversity required to establish balanced immune responses. This phenomenon is proposed to account for some of the dramatic rise in autoimmune and inflammatory disorders in parts of the world where our symbiotic relationship with the microbiota has been the most affected.

  • Evidence suggests that contaminants of emerging concern are potentially harmful, with possible carcinogenic, teratogenic, and mutagenic effects and reproductive developmental toxicity; they may also disrupt gut microbiota and the endocrine system.

    “While the impact of most of these substances on human health is not entirely clear at this point, evidence suggests that they are potentially harmful, with possible carcinogenic, teratogenic, and mutagenic effects and reproductive developmental toxicity [66]; in addition, they may disrupt the normal functioning of gut microbiota [67] and the endocrine system [68].”

    The sections “Induction of regulatory responses by the microbiota” and “Role of the microbiota in IBD and autoimmune disease” describe microbiota-associated immune regulation and limits on gastrointestinal inflammation. They discuss gut and colonic microbiota, however, not microbiota specifically in the stomach; no page numbers are supplied for these passages. (LLM, conf=0.88)

  • Microbiota can modulate gene expression, induce preferential food intake, influence pH, redox balance and the ratio between pro-inflammatory and anti-inflammatory cytokines.

    “endogenous symbiont microorganisms, the so-called microbiota, can modulate gene expression, induce preferential food intake (Aydin, 2007), influence pH, redox balance and the ratio between pro-inflammatory and anti-inflammatory cytokines (Belkaid and Hand, 2014).”
  • Intestinal microbiota influence host physiology.

    “The intestinal microbiota play a role in host physiology.1”
  • The gut microbial population plays a key role in training, functioning and stimulating the host immune system, developing tolerance towards beneficial microbiota and eliciting immune response against gut pathogens.

    “The gut microbial population plays a key role in training, functioning and stimulating the host immune system, with the final effect of developing tolerance towards beneficial microbiota and eliciting immune response against gut pathogens [76].”

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.
