  • Publication number: 20230293656
    Abstract: The result of orally administering saliva derived from a Crohn’s disease patient or an ulcerative colitis patient to germ-free mice has revealed that Th1 cells markedly increased in the colons. Further, from the bacterial microbiota in the intestines of the mice in which such an increase in Th1 cells were observed, bacteria have been successfully isolated which caused strong Th1 cell induction in the colon upon intestinal colonization.

  • Patent number: 11547732
    Abstract: Provided herein are methods of treating graft-versus-host disease in a subject by administering pharmaceutical compositions containing bacterial strains of the Clostridia class. Also described herein are exemplary human-derived bacteria belonging to the Clostridia class, combinations of which have been shown to induce accumulation of regulatory T cells (Treg cells) in the colon and suppress immune functions, and are therefore useful for mitigating pathological immune responses.
