INDUCER FOR INDUCING A TH1 CELL-DOMINANT CONDITION FROM A TH2 CELL-DOMINANT CONDITION

摘要

Disclosed is an inducer that would enable the provision of products such as medical preparations, cosmetic products, foods, and beverages that can improve, treat, or prevent allergic disorders or other inflammatory diseases caused by a Th2 cell-dominant condition, by improving the balance between Th1 cells and Th2 cells and inducing a Th1 cell-dominant condition from a Th2 cell-dominant condition. The invention was completed based on knowledge obtained in studies regarding helper T-cells, which are immunocompetent cells, pertaining to the effects of Grifola frondosa extract and components derived from Grifola frondosa in improving the balance between Th1 cells and Th2 cells, and inducing a Th1 cell-dominant condition.
