Abstract Background Adolescent depression is becoming one of the major public health concerns, because its increased prevalence and risk significant functional impairment suicidality. Clinical commonly emerges in adolescence; therefore, prevention intervention at this stage crucial. Recent evidence supports importance gut microbiota (GM) modulation multiple functions associated with through gut-brain axis (GBA). However, underlying mechanisms remain poorly understood. Therefore, current study, we aimed to screen out from healthy depressive adolescents, delineate association targeted adolescent depression, address salutary effects on anti-depressive behaviors mice involving metabolism tryptophan (Trp)-derived neurotransmitters along GBA.

Abstract Previous studies have shown a bidirectional communication between human gut microbiota and the brain, known as microbiota–gut–brain axis (MGBA). The MGBA influences host's nervous system development, emotional regulation, cognitive function through neurotransmitters, immune modulation, metabolic pathways. Factors like diet, lifestyle, genetics, environment shape composition together. Most research explored how regulates host physiology its potential in preventing treating neurological disorders. However, individual heterogeneity of microbiota, strains playing dominant role diseases, interactions these microbial metabolites with central/peripheral systems still need exploration. This review summarizes driving neurodevelopmental disorders (autism spectrum disorder attention deficit/hyperactivity disorder), neurodegenerative diseases (Alzheimer's Parkinson's disease), mood (anxiety depression) recent years discusses current clinical preclinical microbe‐based interventions, including dietary intervention, probiotics, prebiotics, fecal transplantation.
