Abstract

Phenotypic and functional alteration of murine CD4+ T cells after antigenic stimulation was studied using two anti-T cell mAbs recently described that define four distinct T cell subsets. Activation of T cells resulted in the permanent loss of 3G11 expression. However, two phenotypically distinct memory T cell populations were established depending on the system used; whereas those for anti-KLH antibody response were enriched in the fraction expression 6C10 (Fr. III), memory T cells for the allogeneic MLR lacked such expression (Fr. IV). Furthermore, successive stimulation with antigen in vitro resulted in secretion of IL-4 without detectable IL-2. This alteration of phenotype and interleukin secretion was also demonstrable when starting with 3G11+6C10- cells (Fr. I), the fraction that secretes IL-2 exclusively upon activation.

摘要

利用最近描述的两种抗T细胞单克隆抗体(mAbs)定义四个不同的T细胞亚群,研究了抗原刺激后小鼠CD4 + T细胞的表型和功能改变。T细胞的激活导致3G11表达的永久性丧失。然而,根据所使用的系统建立了两个表型不同的记忆T细胞群体;抗钥孔血蓝蛋白(KLH)抗体反应的记忆T细胞在表达6C10的部分(III组)中富集,而同种异体混合淋巴细胞反应(MLR)的记忆T细胞缺乏这种表达(IV组)。此外,体外连续用抗原刺激导致分泌白细胞介素-4(IL-4)而未检测到白细胞介素-2(IL-2)。当从3G11 + 6C10-细胞(I组)开始时,这种表型和白细胞介素分泌的改变也得到证实,该部分细胞仅在激活时分泌IL-2。
