自噬在体内记忆CD8 T细胞分化中的重要性尚未明确。我们在这里表明,在急性淋巴细胞性脉络膜脑膜炎病毒感染期间,病毒特异性CD8T细胞中的自噬受到动态调节。在激活的增殖T细胞中,自噬功能降低,然后在效应性T细胞反应的高峰期上调。与这一模型一致,病毒特异性CD8T细胞中关键的自噬基因ATG7或ATG5的缺失对产生效应细胞的影响很小,但大大增加了它们在收缩阶段的死亡,从而损害了记忆的形成。这些发现提供了在体内效应和记忆T细胞分化过程中何时需要自噬的洞察力,也值得重新审视我们目前关于T细胞激活和自噬之间的关系的概念。
The importance of autophagy in memory CD8 T cell differentiation in vivo is not well defined. We show here that autophagy is dynamically regulated in virus-specific CD8 T cells during acute lymphocytic choriomeningitis virus infection. Autophagy decreased in activated proliferating T cells, and was then upregulated at the peak of the effector T cell response. Consistent with this model, deletion of the key autophagy genes Atg7 or Atg5 in virus-specific CD8 T cells had minimal effect on generating effector cells but greatly enhanced their death during the contraction phase resulting in compromised memory formation. These findings provide insight into when autophagy is needed during effector and memory T cell differentiation in vivo and also warrant a re-examination of our current concepts about the relationship between T cell activation and autophagy.
