Abstract

T cells play an important role in the pathogenesis of diabetes in the nonobese diabetic (NOD) mouse. CD8 cytotoxic T cell lines and clones were generated from the lymphocytic infiltrate in the islets of Langerhans of young (7-wk-old). NOD mice by growing them on (NOD x B6-RIP-B7-1)F1 islets. These cells proliferate specifically to NOD islets and kill NOD islets in vitro. The cells are restricted by H-2Kd, and all bear T cell antigen receptor encoded by V beta 6. When these CD8 T cell lines and clones are adoptively transferred to irradiated female NOD, young NOD-SCID, and CB17-SCID mice, diabetes occurs very rapidly, within 10 d of transfer and without CD4 T cells.

摘要

T细胞在非肥胖糖尿病(NOD)小鼠糖尿病发病机制中起重要作用。从年轻(7周龄)NOD小鼠胰岛的淋巴细胞浸润中,通过在(NOD×B6-RIP-B7-1)F1胰岛上培养,产生了CD8细胞毒性T细胞系和克隆。这些细胞在体外可特异性增殖至NOD胰岛并杀伤NOD胰岛。这些细胞受H-2Kd限制,均携带由Vβ6编码的T细胞抗原受体。当将这些CD8 T细胞系和克隆过继转移至经辐照的雌性NOD、年轻NOD-SCID和CB17-SCID小鼠时,糖尿病在转移后10天内迅速发生,且无需CD4 T细胞。
