The Bidirectional Gut-Brain Axis: Impact Of Dysbiosis On Depression Through The Hpa Axis, Matan Shiller

The Science Journal of the Lander College of Arts and Sciences

Emerging research suggests that depression is not solely a brain disorder but is deeply influenced by the gut microbiome. The gut-brain axis (GBA) is a bidirectional communication system linking the gastrointestinal system and the brain, modulating mood, behavior, and mental health. Gut microbiota produce metabolites, such as short-chain fatty acids (SCFAs) and tryptophan catabolites, that influence neurotransmission and the stress response via the hypothalamic-pituitary-adrenal (HPA) axis. Dysbiosis, or microbial imbalance, disrupts these pathways, contributing to a major depressive disorder (MDD). Evidence from germ-free animal studies and fecal microbiota transplants (FMT) highlights the role of gut microbiota in emotional regulation and …
