SCREENING METHOD FOR ORAL IMMUNOLOGICAL TOLERANCE-ENHANCING MATERIAL, AND ORAL IMMUNOLOGICAL TOLERANCE-ENHANCING COMPOSITION

摘要

PROBLEM TO BE SOLVED: To provide a screening method for materials/lactic acid bacteria for enhancing oral immunological tolerance, and to provide compositions based on the lactic acid bacteria.SOLUTION: This invention provides a screening method for oral immunological tolerance-enhancing materials, comprising a step of evaluating a test material that promotes the production of interferonβas an oral immunological tolerance enhancing material. This invention also provides oral immunological tolerance enhancing compositions comprising lactic acid bacterium cultures, bacterial cells of lactic acid bacteria or bacterial cell components of lactic acid bacteria as active ingredients.
