Abstract

Adult mice can be depleted of essentially all mature alpha beta T lymphocytes by chronic treatment with the framework-recognizing, pan-specific anti-TCR alpha beta mAb, H57-597. Similar findings have been reported in rats, gamma delta cell populations remain essentially unaltered in size and reactivity. Suppression of alpha beta T-cell development results in the loss of alloantigen reactivity and of B-cell help, suggesting that gamma delta and alpha beta populations differ in their functional capabilities. Indirect effects of the antibody treatment include quantitative changes in splenic B cells, as well as reduced sizes and weights of experimental animals. alpha beta-suppressed mice and rats may provide model systems for studies on gamma delta cell function in vivo.

摘要

通过用识别框架的泛特异性抗TCRαβ单克隆抗体H57-597进行长期治疗,成年小鼠基本上所有成熟的αβT淋巴细胞都可被清除。在大鼠中也有类似的发现,γδ细胞群体的大小和反应性基本保持不变。αβT细胞发育的抑制导致同种异体抗原反应性和B细胞辅助功能的丧失,这表明γδ和αβ细胞群体在功能能力上存在差异。抗体治疗的间接影响包括脾B细胞的数量变化,以及实验动物的体型和体重减轻。αβ细胞被抑制的小鼠和大鼠可能为体内γδ细胞功能的研究提供模型系统。
