Abstract

Gut microbiota dysbiosis has been considered the essential element in the pathogenesis of multiple sclerosis and its animal model, experimental autoimmune encephalomyelitis (EAE). Antibiotics were administered orally to Dark Agouti (DA) rats early in their life with the aim of perturbing gut microbiota and investigating the effects of such intervention on the course of EAE. As a result, the diversity of the gut microbiota was reduced under the influence of antibiotics. Mainly, Firmicutes and Actinobacteria were replaced by Proteobacteria and Bacteroidetes, while decreased proportions of Clostridia and Bacilli classes were accompanied by an increase in Gamma-Proteobacteria in antibiotic-treated animals. Interestingly, a notable decrease in the Helicobacteraceae, Spirochaetaceae and Turicibacteriaceae was scored in antibiotic-treated groups. Also, levels of short chain fatty acids were reduced in the faeces of antibiotic-treated rats. Consequently, aggravation of EAE, paralleled with stronger immune response in lymph nodes draining the site of immunization, and increased inflammation within the CNS, were observed in antibiotic-treated DA rats. Thus, the alteration of gut microbiota leads to an escalation of CNS-directed autoimmunity in DA rats. The results of this study indicate that antibiotic use in early life may have subsequent unfavourable effects on the regulation of the immune system.

  • The central nervous system becomes more prone to extreme inflammatory responses when the microbiota is depleted by antibiotics early in life.

    “the CNS, which becomes more prone to extreme inflammatory responses when the microbiota is depleted by antibiotics early in life (104).”

    From The Role of Short-Chain Fatty Acids From Gut Microbiota in Gut-Brain Communication (2020) · cites this paper as [104]

    The Results (‘Effects of antibiotic treatment on EAE’) report more severe induced CNS autoimmune disease in rats treated with antibiotics early in life, including more spinal-cord immune-cell infiltration and higher inflammatory cytokine levels. The claim omits that this was shown in EAE-susceptible rats after a later immune challenge, and ‘extreme inflammatory responses’ is stronger and broader than the reported finding. (LLM, conf=0.85)

    Experimental — accuracy not yet measured
  • Antibiotic-treated and germ-free mice have pro-inflammatory systemic and CNS immune responses.

    “Antibiotic-treated and germ-free mice have pro-inflammatory systemic and CNS immune system responses (120, 267).”

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.
