| Outline of Final Research Achievements |
Experimental autoimmune orchitis (EAO) is one of the models of immunological male infertility. To establish a highly reproducible model of EAO, in 2011, we found that only one placement of a syngeneic donor’s testes, epididymides and vasa deferentia into the abdominal cavity was sufficient to induce EAO on the recipient’s testes in mice. It was also noted that the placement of testes, epididymides and vasa deferentia induced only orchitis without epididymo-vasitis. At the next three years, the testicular autoantigens were identified using sera obtained from EAO-affected mice. The testicular proteins were separated using two-dimensional gel electrophoresis, and the autoantigens proteins were identified by Western blotting and Mass spectrometry. Some identified testicular specific autoantigens have not been reported previously, and the clarification of these proteins will facilitate new approaches for understanding EAO.
