Microbiota–gut–brain axis and its therapeutic applications in neurodegenerative diseases
The gut microbiota has been found to interact with the brain through the microbiota-gut-brain axis, regulating various physiological processes.
The relationship between the gut microbiota and brain function through bidirectional communication, described as "the microbiome-gut-brain axis", is especially underlined.
The microbiota and the brain communicate with each other via various routes including the immune system, tryptophan metabolism, the vagus nerve and the enteric nervous system, involving microbial metabolites such as short-chain fatty acids, branched chain amino acids, and peptidoglycans.

The review states that microbiota composition is shaped by early-life factors including infection, birth delivery mode, antibiotic use, nutrition, environmental stressors, and host genetics, and that microbial diversity diminishes with aging.
Many factors can influence microbiota composition in early life, including infection, mode of birth delivery, use of antibiotic medications, the nature of nutritional provision, environmental stressors, and host genetics. At the other extreme of life, microbial diversity diminishes with aging.
