调节T细胞记忆产生的过程对于治疗设计和对疾病的免疫应答很重要。然而,是什么让效应T细胞的一个子集在收缩期存活下来,成为记忆细胞还不完全清楚。Bcl-2家族对于T细胞存活至关重要,并且已经提出Bcl-2对于记忆细胞的存活是重要的。然而,以前的研究依赖于双敲除模型,可能会扭曲Bcl-2的作用,并且由于蛋白质的细胞内定位,在过继转移实验中使用Bcl-2作为标记物是不可能的,过继转移实验是确认细胞亚群记忆潜力所需的方法。在这项研究中,我们提出了一种新型的Bcl-2报告基因小鼠模型,并首次表明效应T细胞的一个不同子集,以及CD 127 hiKLRG 1 lo记忆前体效应细胞(MPEC)群体中的一个子集,在峰值时保留了高Bcl-2表达CD 8 + T细胞对单核细胞增生李斯特菌的反应。此外,我们表明,Bcl-2与记忆潜力过继转移实验中使用的总响应CD 8 + T细胞和MPECs。这些结果表明,即使在MPEC群体中,Bcl-2也在效应CD 8 + T细胞亚群中赋予存活优势,其允许分化为记忆细胞并巩固Bcl-2作为T细胞记忆的关键因子。
The processes that regulate T cell memory generation are important for therapeutic design and the immune response to disease. However, what allows a subset of effector T cells to survive the contraction period to become memory cells is incompletely understood. The Bcl-2 family is critical for T cell survival, and Bcl-2 has been proposed to be important for the survival of memory cells. However, previous studies have relied on double-knockout models, potentially skewing the role of Bcl-2, and the use of Bcl-2 as a marker in adoptive transfer experiments, a method required to confirm the memory potential of cell subsets, has not been possible due to the intracellular localization of the protein. In this study, we present a novel Bcl-2-reporter mouse model and show for the first time that a distinct subset of effector T cells, and also a subset within the CD127hiKLRG1lo memory precursor effector cell (MPEC) population, retains high Bcl-2 expression at the peak of the CD8+ T cell response to Listeria monocytogenes. Furthermore, we show that Bcl-2 correlates with memory potential in adoptive transfer experiments using both total responding CD8+ T cells and MPECs. These results show that even within the MPEC population, Bcl-2 confers a survival advantage in a subset of effector CD8+ T cells that allows differentiation into memory cells and cement Bcl-2 as a critical factor for T cell memory.
