Bifidobacteria and Psychobiotic Therapy: Current Evidence and Future Prospects

Mounting evidence elucidates the impact of gut microbiota on maintenance host’s physical and psychological conditions. The can produce its effects through neural, endocrine, immune pathways. Specific members, such as lactobacilli bifidobacteria, have shown unique abilities to affect mental health, hence, they are called psychobiotics. Several studies, both rodents humans, confirmed role Bifidobacterium in regulation anxiety, mood, cognition, pain. Here, we summarize currently available that suggests roles bifidobacteria microbiota–brain communication highlight prospects this research field. action has been found be strain specific. We discuss here reported mechanisms different strains. However, more strategic investigations needed fully understand detailed psychobiotic bacteria.
