| Outline of Final Research Achievements |
The nucleoprotein Thy28 molecule has been shown to control antigen receptor-mediated cell death of B and T cells in vitro. We made Thy28TG mice and examined the role of Thy28. Thymic cell death induced by administration of anti-CD3 is suppressed compared to wild-type mice, and suppression of JNK activation and Bcl-xL down-regulation is observed along with suppression of this anti-CD3-induced cell death. It was speculated that Thy28 TG mice were highly sensitive to EAE induced by self-peptides, and the cause thereof was the increase in IFN-g production induced by CD4-positive naive T cells.

| Academic Significance and Societal Importance of the Research Achievements |
JNK活性化にも関与するThy28がアポトーシス誘導に関わっていることが示唆された。今後さらに実験を重ねThy28機能的役割を明らかにすることによって、アポトーシス誘導機構、さらには癌、自己免疫疾患などの誘導の解明に寄与すると期待できる。
