MYCOBACTERIUM VACCAE FOR DOWN-REGULATION OF THE TH2 ACTIVITY OF THE IMMUNE SYSTEM

摘要

Antigenic and/or immunogenic material derived from Mycobacterium vaccae is used to down-regulate Th2 activity of the immune system without up-regulation of Th1 activity. Disorders such as Chronic Fatigue Syndrome, Gulf War Syndrome and Total Allergy Syndrome are treated. The material preferably comprises dead M. vaccae cells in a composition which does not include a non-M. vaccae antigen, immunogen or allergen.
