作为适应性免疫反应的核心特征,免疫记忆的发育要求在很大程度上是模糊的。我们发现,在没有明显抗原刺激的情况下,淋巴细胞减少的小鼠中,初始CD8 T细胞经历稳态驱动的增殖,它们逐渐获得抗原诱导的记忆性CD8 T细胞的表型和功能特征。因此,内稳态诱导的记忆性CD8 T细胞表达典型的记忆细胞标记物,在体外和体内直接裂解靶细胞,对抗原的反应比初始细胞低,并且在再刺激时分泌干扰素γ更快。与抗原诱导的记忆性T细胞分化一样,内稳态驱动的过程需要T细胞增殖,并且最初需要适当的限制性主要组织相容性复合物的存在,但其不同之处在于,它不需要效应细胞形成,也不需要白细胞介素2或CD28的共刺激。这些发现定义了重复细胞分裂加上T细胞受体连接是幼稚记忆T细胞分化的基本要求。
The developmental requirements for immunological memory, a central feature of adaptive immune responses, is largely obscure. We show that as naive CD8 T cells undergo homeostasis-driven proliferation in lymphopenic mice in the absence of overt antigenic stimulation, they progressively acquire phenotypic and functional characteristics of antigen-induced memory CD8 T cells. Thus, the homeostasis-induced memory CD8 T cells express typical memory cell markers, lyse target cells directly in vitro and in vivo, respond to lower doses of antigen than naive cells, and secrete interferon γ faster upon restimulation. Like antigen-induced memory T cell differentiation, the homeostasis-driven process requires T cell proliferation and, initially, the presence of appropriate restricting major histocompatibility complexes, but it differs by occurring without effector cell formation and without requiring interleukin 2 or costimulation via CD28. These findings define repetitive cell division plus T cell receptor ligation as the basic requirements for naive to memory T cell differentiation.
