The gut microbiota reduces the production of retinoic acid, a metabolite of vitamin A, to regulate immune activity and prevent pathogens.
A group of cell-wall sugar molecules stimulate the production of pTreg cells, which reduce inflammation and prevent autoimmunity.
A review published in Journal of Innate Immunity supports a role of gut microbes in alleviating or even preventing graft-versus-host disease (GvHD).
