Abstract
Assessment of thymic output by measurement of naive T cells is carried out routinely in clinical diagnostic laboratories, predominantly using flow cytometry with a suitable panel of antibodies. Naive T cell measurements can also be made using molecular analyses to quantify T cell receptor excision circle (TRECs) levels in sorted cells from peripheral blood. In this study we have compared TRECs levels retrospectively with CD45RA CD27 T cells and also with CD45RA CD31 T cells in 134 patient samples at diagnosis or during follow-up. Both panels provide naive T cell measurements that have a strongly positive correlation with TRECs numbers and are suitable for use with enumerating naive T cell levels in a clinical laboratory.
摘要
通过测量幼稚 T 细胞来评估胸腺输出在临床诊断实验室中是常规进行的，主要使用流式细胞术和适当的抗体组合。幼稚 T 细胞的测量也可以使用分子分析来定量外周血分选细胞中的 T 细胞受体切除环 (TRECs) 水平。在这项研究中，我们回顾性地比较了 134 个患者样本在诊断或随访时的 TRECs 水平与 CD45RA CD27 T 细胞和 CD45RA CD31 T 细胞。这两个面板都提供了与 TRECs 数量具有强烈正相关的幼稚 T 细胞测量值，适用于在临床实验室中计数幼稚 T 细胞水平。
