  • Publication number: 20170007691
    Abstract: It was found that bacteria belonging to the genus Clostridium induce accumulation of regulatory T cells (Treg cells) in the colon. Moreover, the present inventors found that regulatory T cells (Treg cells) induced by from these bacteria suppressed proliferation of effector T-cells. From these findings, the present inventors found that the use of bacteria belonging to the genus Clostridium or a physiologically active substance derived therefrom made it possible to induce proliferation or accumulation of regulatory T cells (Treg cells), and further to suppress immune functions.

  • Publication number: 20160193257
    Abstract: Species of human-derived bacteria belonging to the Clostridia class have been shown to induce accumulation of regulatory T cells (Treg cells) in the colon and suppress immune functions. Pharmaceutical compositions containing these bacteria can be used to prevent and treat immune-mediated diseases such as autoimmune diseases.

  • Publication number: 20160144014
    Abstract: Compositions consisting of bioactive molecules derived from the microbiota of a mammal are provided herein. When administered orally with a colonic delivery system, the compositions are useful for the prophylaxis and treatment of diseases, in particular inflammatory, autoimmune and infectious diseases. The compositions comprise combinations of small molecules and bacterial antigens formulated in colonic delivery systems. Use of the compositions results in any or all of: induction of immune tolerance; strengthening of the gut mucosal barrier integrity; reduction of inflammation; and amelioration of a disease state caused by inflammation, an autoimmune reaction or an infectious agent.
