Abstract

A new human T cell subset defined by antineuronal ganglioside mAb 3G5 increases linearly with advancing age in man. The percentage of circulating 3G5+ T cells in 21 normal individuals, quantitated by cytofluorograph analysis, increases linearly from age 7 (23-30%) to age 84 (58%) (r = 0.85, p less than 0.001). The antigen on T cells has the biochemical properties of a ganglioside that migrates between GM1 and GM2 ganglioside markers on TLC. The 3G5 subset represents the first T cell subset that reflects aging in man.

摘要

一种由抗神经元神经节苷脂单克隆抗体3G5定义的新型人类T细胞亚群在人类中随年龄增长呈线性增加。通过细胞荧光分析定量检测的21名正常个体中循环3G5 + T细胞的百分比,从7岁时的23 - 30%线性增加到84岁时的58%(r = 0.85,p < 0.001)。T细胞上的抗原具有神经节苷脂的生化特性,在薄层层析上介于GM1和GM2神经节苷脂标记物之间迁移。3G5亚群是第一个反映人类衰老的T细胞亚群。
