Immunomodulation by commensal and probiotic bacteria

Forsythe, Paul, Bienenstock, John·2010·Immunological Investigations

Abstract

Over the past decade there has been an increasing awareness of the role played by commensal bacteria in modulating mucosal immune responses and as a consequence there is now great interest in the therapeutic potential of probiotics and other bacteria based strategies for a range of immune disorders. Here we review current understanding of the mechanisms underlying the immunomodulatory actions of commensal and probiotic bacteria and probiotic organisms. We discuss prominent cell types involved in transducing signals from these bacteria, including epithelial cells, dendritic cells and T regulatory cells. We also draw attention to emerging data indicating interplay between the gut microbiota, enteric neurons and the immune system. There is a focus on the specific aspects of bacteria-host interactions that may influence the ability of a specific organism to confer potentially beneficial changes in immune responses. It is clear that there is still much to learn regarding the determinants of the diverse immune responses elicited by different bacterial strains by building on our current knowledge in these areas it may be possible to design clinically effective, bacteria based strategies to maintain and promote health.

This paper’s full text isn’t openly available, 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?

  • Microbiota affects circulating levels of melatonin, serotonin, histamine, and acetylcholine, which are important for brain maturation.

    “Furthermore, the microbiota affects the circulating levels of other mediators and substances, such as melatonin, serotonin, histamine and acetylcholine [168,169], which are important for brain maturation [170].”

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.
