Abstract

Increasing awareness of the role of intestinal commensal bacteria in the development and modulation of the immune system has led to great interest in the therapeutic potential of probiotics and other bacteria-based strategies for a range of immune-related disorders. Studies in animal models have identified strong immunomodulatory effects of many nonpathogenic bacteria and provided evidence that intestinal microbes can activate a common mucosal immune response and, thus, influence sites distant to the intestine, including the respiratory tract. Respiratory effects of probiotics in animal models have included attenuating allergic airway responses and protecting against respiratory pathogens. Dendritic cells appear central to directing the beneficial immune response to probiotic bacteria and in translating microbial signals from the innate to the adaptive immune system, whereas regulatory T cells are emerging as potentially key effectors of probiotic-mediated responses, particularly in the reduction of allergic inflammation. Despite progress in basic research, clinical trials of probiotics in allergy/asthma and respiratory infection have been highly variable at best, leading to an undermining of confidence in this potential therapeutic strategy. It is clear that there is still much to learn regarding the determinants of the diverse immune responses elicited by different bacterial strains. A deeper knowledge of the interactions between administered probiotics and the existing microbiota, together with an understanding of how the dialogue between microbes and the innate immune system is translated into beneficial/protective responses, will be required before we can achieve clinically effective bacteria-based strategies that maintain and promote respiratory health.

We couldn’t retrieve this paper’s full text, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Probiotic treatment may modulate immune response in the lung; in particular gut microbial stimulation can enhance T regulatory response in the airway, which emphasizes the potential role of probiotics in the pulmonary inflammatory response.

    “It is also important to note that probiotic treatment may modulate immune response in the lung; in particular gut microbial stimulation can enhance T regulatory response in the airway, which emphasizes the potential role of probiotics in the pulmonary inflammatory response [89] .”

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.
