| Outline of Final Research Achievements |
Sarcoidosis is an inflammatory disorder of unknown etiology, featured by granuloma formation in the eye, lung, and skin. Recent studies revealed that propionibacterium acnes, normal bacterial flora in the skin, is present in the granuloma, and it is implicated that immune reaction against P. acnes is the cause of sarcoidosis. In this study, we attempted to establish P. acnes infected mice by tail vein injection of viable P. acnes, and to establish animal model of granulomatous inflammation by inducing cellular immunity against P. acnes by active immunization. As a result, most of the experimental mice showed granuloma formation and positive signal against P. acnes in the granuloma by immunohistochemical analysis. However, there was no granuloma or inflammation in the eye.
