| Outline of Final Research Achievements |
We examined whether induction of lesions similar to GPA could be induced by administering MPO antibody to a model that causes tuberculosis similar lesions in mice.By immunizing MPO knockout mouse, anti - MPO antibody was successfully produced. According to previous reports, the antibodies were administered to B6 mice, but it was not possible to efficiently induce renal vasculitis. There was also report that it was difficult to reproduce the model, and when LPS was added and antibody was administered, it succeeded in inducing nephritis. When TDM was administered to B6 mice with antibodies, results indicating an increase tendency of granulomatous lesions were obtained, but it was difficult to obtain reproducibility. Assuming that the antibody is currently involved in the repairing disorder of pulmonary granulomas, we are conducting experiments to observe the recovery period of granuloma.
