Abstract

Significance: Stress cannot be avoided in the present competitive world, and chronic stress is associated with detrimental effects on physical health, including the progression of inflammatory bowel disease (IBD). However, the mechanisms behind it are less clearly understood. This study showed that chronic stress disturbed gut microbiota, thereby triggering immune system response and facilitating dextran sulfate sodium-induced colitis. Results also showed stress-deficient expression of mucin-2 and lysozyme, which may contribute to the disorder of gut microbiota. This study adds to our understanding of interactions between microbiota and host and provides the basis for future clinical studies of microbiota manipulation and transplantation and the development of new therapeutic strategies for depression or IBD.

  • Animals exposed to chronic stress are more prone to develop inflammatory conditions such as experimental autoimmune encephalitis, colitis, atherosclerosis and diabetes.

    “Moreover, animals that are exposed to chronic stress are predisposed to the development of inflammatory conditions, such as experimental autoimmune encephalitis, colitis, atherosclerosis and diabetes31–34.”

    Experimental — accuracy not yet measured
  • In mice with induced colitis, chronic stress was associated with a significant increase in inflammation-enhancing bacteria.

    “More specifically, a study of mice with induced colitis found that chronic stress was associated with a significant increase in inflammation-enhancing bacteria (15).”
  • Stress disturbs the gut microbiota, triggers immune system dysfunction, and facilitates DSS-induced colitis.

    “In general, stress disturbs the gut microbiota, triggers immune system dysfunction and facilitates DSS-induced colitis (47).”
  • When the intestinal microbiota was shared by cohousing or destroyed by antibiotics, the severity of DSS-induced colitis was indistinguishable between the stressed and control groups, suggesting that the gut microbiota is responsible for the deleterious effects of stress.

    “In contrast, when the intestinal microbiota was shared by cohousing or was destroyed by antibiotics, the severity of DSS-induced colitis was indistinguishable between the stressed and control groups, unequivocally suggesting that the gut microbiota is responsible for the deleterious effects of stress.”
  • A recent study based on a DSS-induced colitis model provided evidence that chronic stress increases sensitivity to colitis via dysbiosis and immune system dysfunction.

    “A recent study based on a dextran sulfate sodium (DSS)-induced colitis model provided evidence that chronic stress increases sensitivity to colitis via dysbiosis and immune system dysfunction.”

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.
