Abstract

Wound healing capability is inextricably linked with diverse aspects of physical fitness ranging from recovery after minor injuries and surgery to diabetes and some types of cancer. Impact of the microbiome upon the mammalian wound healing process is poorly understood. We discover that supplementing the gut microbiome with lactic acid microbes in drinking water accelerates the wound-healing process to occur in half the time required for matched control animals. Further, we find that Lactobacillus reuteri enhances wound-healing properties through up-regulation of the neuropeptide hormone oxytocin, a factor integral in social bonding and reproduction, by a vagus nerve-mediated pathway. Bacteria-triggered oxytocin serves to activate host CD4+Foxp3+CD25+ immune T regulatory cells conveying transplantable wound healing capacity to naive Rag2-deficient animals. This study determined oxytocin to be a novel component of a multi-directional gut microbe-brain-immune axis, with wound-healing capability as a previously unrecognized output of this axis. We also provide experimental evidence to support long-standing medical traditions associating diet, social practices, and the immune system with efficient recovery after injury, sustained good health, and longevity.

  • Effects of Lactobacillus on host plasma and hypothalamic oxytocin are dependent on vagal signaling.

    “Interestingly, the effects observed above are dependent on vagal signaling, which blunted the effects of Lactobacillus on host plasma and hypothalamic oxytocin [132,133].”
  • L. reuteri increases oxytocin levels.

    “We and others have shown that L. reuteri increases oxytocin levels (Buffington et al., 2016; Poutahidis et al., 2013).”
  • L. reuteri increases oxytocin levels, based on prior correlational evidence.

    “We and others have previously provided correlational evidence that L. reuteri increases oxytocin levels (Buffington et al., 2016; Poutahidis et al., 2013)”
  • Administration of L. reuteri to mice results in an increase in the circulation levels and expression of oxytocin, which was associated with an increase in social behavior.

    “Indeed, administration of L. reuteri, to mice resulted in an increase in the circulation levels and expression of oxytocin, which was associated with an increase in social behavior (Buffington et al., 2016;Poutahidis et al., 2013).”

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.
