Probiotics that reduce immune reactions and their effects on pain-related nerves in brain-immune disorders

AI simplified

Abstract

Tolerogenic probiotics may offer therapeutic potential for neuroimmune disorders by affecting the gut-brain axis.

  • These probiotics help promote immune tolerance and reduce inflammation in the body.
  • They influence crucial cell types, including intestinal epithelial cells and enteroendocrine cells, which are important for gut health.
  • Probiotics enhance the integrity of the gut barrier and regulate the secretion of hormones like GLP-1 and serotonin.
  • They may help alleviate various types of pain by modulating key receptors involved in pain signaling.
  • Challenges such as inconsistent dosing and limited clinical trials may hinder their effective use in clinical settings.
