Abstract:
The interplay between microbiota and nervous system has been associated with a variety of diseases, including stress, anxiety, depression and cognition. The growing body of evidences on the essential role of gut microbiota in modulating acute and chronic pain has opened a new frontier for pain management. Gut microbiota is involved in the development of visceral, inflammatory and neuropathic pain. Bacterial alterations due to chronic opioid administration have been directly related to the development of drug tolerance, which can be potentially restored by the use of probiotics and antibiotics. In this review we describe the mechanisms underlying the brain/gut axis and the relationship between gut microbiota, immunity and pain.
