Novel Aspects of Enteric Serotonergic Signaling in Health and Brain-Gut Disease.

Novel Aspects of Enteric Serotonergic Signaling in Health and Brain-Gut Disease. Am J Physiol Gastrointest Liver Physiol. 2019 Nov 04;: Authors: Del Colle A, Israelyan N, Gross Margolis KG Abstract Gastrointestinal comorbidities are common in individuals with mood and behavioral dysfunction. Similarly, patients with gastrointestinal problems more commonly suffer from co-morbid psychiatric diagnoses. Though the central and enteric nervous systems (CNS and ENS, respectively) have largely been studied separately, there is emerging interest in factors that may contribute to disease states involving both systems. There is strong evidence to suggest that serotonin may be an important contributor to these brain-gut conditions. Serotonin has long been recognized for its critical functions in CNS development and function. The majority of the body's serotonin is produced in the GI tract, where it also plays keys roles in ENS development and function. Further understanding of the specific impact that enteric serotonin has on brain-gut disease may lay the foundation for the creation of novel therapeutic targets. This review summarizes the current data focusing on the important roles that serotonin plays in ENS development and function that form the basis of the current research focusing on novel aspects of serotonergic signaling in medical conditions in which CNS and ENS co-morbidities are common, including autism spectrum disorders and depressi...
