| Outline of Final Research Achievements |
The aim of the present study was to determine the significance of ISG15, which is induced by viral infection, and KLRC3, which is known as an activating receptor of NK cells in the development of fulminant type 1 diabetes mellitus.
We found that ISG15 acted as an inhibitor of apoptosis by inflammatory cytokines by using overexpression and knockdown methods in MIN6 cells, mouse beta cell line. We also found that the gene expressions of KLRC3 (NKG2E) and CD94, its heterodimer, were reduced in peripheral NK cells of fulminant type 1 diabetic patients.
Overall, we have clarified two candidates of key molecules in the beta cell destruction of fulminant type 1 diabetes.
