摘要Sarcoidosis is a systemic disease of unknown etiology characterized by the formation of noncaseating granulomas.Its clinical manifestations are heterogeneous,and the determinants of clinical course(such as active vs inac-tive,remission vs chronic progression,and fibrosis vs non-fibrosis)are poorly understood.Despite considerable effort over many years,the exact pathogenesis of sarcoidosis has not been fully elucidated.Animal models have made significant con-tributions to understanding the etiology and the development of this disease.In this review,we presented the clinical rele-vance of animal models in sarcoidosis,summarized the methods for constructing the models,and discussed how they have strengthened our understanding of sarcoidosis.
