T-box 转录因子 T-bet 已知可控制辅助 T 1 (Th1) CD4 淋巴细胞的谱系定型和干扰素 γ 产生。我们在此报告,在病毒诱导的 T1D 大鼠胰岛素启动子-淋巴细胞脉络膜脑膜炎病毒 (LCMV) 转基因模型中,T-bet 对于 CD8 淋巴细胞依赖性自身免疫性糖尿病(1 型糖尿病 [T1D])的发展至关重要。在没有 T-bet 的情况下,与对照组相比,自身攻击性(抗 LCMV)CD8 淋巴细胞数量减少,产生的 IFN-γ 减少,但 IL-2 增加。进一步分析表明,T-bet 本质上控制抗病毒效应/记忆 CD8 淋巴细胞的生成,但不控制凋亡、维持或二次扩增。这一观察结果为治疗 T1D 和其他自身免疫性疾病提供了治疗机会。
The T-box transcription factor T-bet is known to control lineage commitment and interferon-γ production by T helper 1 (Th1) CD4 lymphocytes. We report here that T-bet is essential for development of CD8 lymphocyte-dependent autoimmune diabetes (type 1 diabetes [T1D]) in the rat insulin promoter–lymphocytic choriomeningitis virus (LCMV) transgenic model for virally induced T1D. In the absence of T-bet, autoaggressive (anti-LCMV) CD8 lymphocytes were reduced in number and produced less IFN-γ, but increased IL-2 compared with controls. Further analysis showed that T-bet intrinsically controls the generation, but not apoptosis, maintenance, or secondary expansion of antiviral effector/memory CD8 lymphocytes. This observation points toward a therapeutic opportunity for the treatment of T1D and other autoimmune disorders.
