| Research Abstract |
Cardiac sarcoidosis is a chronic disease of unknown etiology characterized by the formation of non-necrotizing epitheloid granulomas. The lack of an adequate animal model reflecting the pathogenesis of the human disease is one of the major impediments in studying sarcoidosis. The purpose of this study was to generate a mouse model of cardiac sarcoidosis to understand its pathogenesis and develop clinical diagnostic and therapeutic strategies.
Apo E-/- mice after 16 weeks on a cholate-containing high-fat diet exhibited macrophage accumulation and interstitial fibrosis in the myocardium where no lymphocytes were observed. Thus, the model presented myocarditis strongly associated with macrophages. Inflammation mainly associated with macrophages could be detected by F-18 FDG PET, but normal myocardial cells also utilize FDG. A clinical study showed FDG PET with a fast of 18 h< can detect active lesions of cardiac sarcoidosis by suppressing normal uptake of myocardium.
