我们在这里证明了小鼠胸腺中存在不同的成熟CD 4 +8- T细胞亚群。该亚群被称为“Thy 0”,通过从约一半的CD 4 +8-胸腺细胞的6C 10-/HSA低/-级分中不存在3G 11表达来描述。Thy 0在新生儿期就可检测到,并在很大程度上促进了以前报道的HSA低/-CD 4+胸腺人群的Th 0型多种细胞因子产生。此外,表达T细胞受体V β 8基因家族的细胞在Thy 0中的频率随着年龄的增长而增加,在成年BALB/c小鼠中占Thy 0的40-60%。这种V β 8+细胞频率的改变是Thy 0所独有的,因为胸腺或脾脏中没有其他CD 4+亚群显示出这种V β 8过度使用。所有功能性CD 4 + T细胞亚群,包括Thy 0,均显示与内源性超抗原相关的适当V β克隆缺失。因此,Thy 0似乎是在CD 4 + T细胞选择后产生的胸腺内产生的次级细胞亚群。
We demonstrate here the presence of a distinct mature CD4+8- T cell subset in mouse thymus. This subset, termed "Thy0," is delineated by the absence of 3G11 expression from about half of the 6C10-/HSAlow/- fraction of CD4+8- thymic cells. Thy0 is detectable from the neonatal period and largely contributes the Th0-type diverse cytokine production previously reported for the HSAlow/-CD4+ thymic population. Further, cells expressing the T cell receptor V beta 8 gene family are found at increasing frequency in Thy0 with age, comprising 40-60% of Thy0 in adult BALB/c mice. This alteration of V beta 8+ cell frequency is unique to Thy0, since no other CD4+ subset in thymus or spleen shows such V beta 8 overusage. All functional CD4+ T cell subsets, including Thy0, show appropriate V beta clonal deletion associated with endogenous superantigens. Thus, it appears that Thy0 is an intrathymically generated secondary cell subset produced after CD4+ T cell selection.
