Abstract

F1 animals were tolerized to 1-fluoro-2,4-dinitrobenzene (DNFB) contact sensitivity with parentally derived, in vitro hapten-modified spleen cells. This tolerant state was found, upon adoptive transfer to naive parental strain recipients, to affect only that T cell subpopulation that recognized the parental haplotype of the cell used as the tolerogen, and did not inhibit the ability of the remaining T cell subset to confer immunity. This demonstrates that this tolerant state involves the inactivation of a cell required for the expression of contact sensitivity by recognizing DNFB in association with self major histocompatibility complex gene products.

摘要

用亲代来源的、体外经半抗原修饰的脾细胞使F1代动物对1-氟-2,4-二硝基苯(DNFB)接触敏感性产生耐受。当将这种耐受状态过继转移给未接触过的亲代品系受体时,发现它仅影响识别用作耐受原的细胞的亲代单倍型的T细胞亚群,而不抑制其余T细胞亚群赋予免疫的能力。这表明这种耐受状态涉及通过识别与自身主要组织相容性复合体基因产物相关联的DNFB来使接触敏感性表达所需的细胞失活。
