Approximately 95% of the symbiotic microbes in human body are located in the gut. This microbioma is involved in important homeostatic processes, not only related to gastrointestinal function but also to several complex modulatory processes, such as glucose and bone metabolism, inflammation and immune response, peripheral (enteric) and central neurotransmission. For that reason, recent studies proposed that abnormalities in gut microbiota may play a role in systemic and central nervous system (CNS) conditions. Therefore, the integrity of gut microbiota be relevant to the pathophysiology and control of important medical diseases like diabetes mellitus, inflammatory and autoimmune diseases, and even neuropsychiatric disorders such as depression, autism spectrum disorder, Parkinson's and Alzheimer disease. Gut microbiota may affect brain function and behaviour through the microbiota-gut-brain axis, in bidirectional interplay with top-down and bottom-up regulations. Through metabolic activity of non- pathogenical...
