Human gut microbiota and its association with pathogenesis and treatments of neurodegenerative diseases

Abstract

Human gut microbiota consists of various microorganisms whose numbers are similar to those of human cells. Human gut microbes and the brain form bidirectional communications through the brain-gut-axis, and play a central role in normal physiological processes and in pathogenesis of many human diseases. Accumulating evidence has demonstrated the crucial effect of gut microbes in proper brain functions and under disease conditions. Here we first focus on revealing current knowledge of the role of gut microbes in neural development and functions. We then summarize mutual relationships between gut microbes and human diseases, in particular neurodegenerative disorders such as Alzheimer's disease, Parkinson's disease and Multiple sclerosis. Finally, we highlight ongoing studies in exploring gut microbes in treatments of human diseases. Applying gut microbes as a means in treatment of human diseases is becoming a promising research direction, and has a great potential in clinical practice.
