The gut microbiota and associated metabolites in multiple sclerosis


Multiple sclerosis




Multiple sclerosis (MS) is a severe central nervous system autoimmune inflammatory disease featured by the presence of infiltrated immune cells, demyelination, and degeneration. Recent research has shown that gut microbiota, including some commensal bacteria, is capable of interacting with the host immune system and remarkably influencing the development and outcome of experimental autoimmune encephalomyelitis, a classic animal model of MS. In addition, gut dysbiosis, presented with a significantly altered composition of commensal bacteria, is linked to the immune response and inflammation, such as Th17 activation and B cell function. Moreover, it has been observed that microbiota impacts the immune system by regulating the metabolites in the gut. In this review, we summarize the new research on the relationship and mechanism between the gut microbiota and MS, as well as the implications for developing new strategies in MS by modulating the gut microbiota and metabolites.
