| 摘要 |
The present invention provides a non-human model animal of Goodpasture's syndrome that contributes to the treatment of Goodpasture's syndrome where the development of therapy had been delayed due to the lack of adequate disease models, a method for screening a remedy for Goodpasture's syndrome by using the model animal, and a method for diagnosing Goodpasture's syndrome at the early stage. A Goodpasture's syndrome model mouse is constructed by immunizing immunoglobulin Fcgamma receptor IIB knockout mouse with type IV collagen, thereby inducing Goodpasture's syndrome. Moreover, a remedy for Goodpasture's syndrome is screened by administration of test substances to the Goodpasture's syndrome model mouse, followed by evaluating the severity of the expression of Goodpasture's syndrome as an index, such as diffuse alveolar hemorrhage, glomerulonephritis, the appearance of antikidney glomerular basement membrane antibody, and the like.
