Abstract

The specificity of C57BL/10 cytotoxic effector cells generated by in vitro sensitization with autologous spleen cells modified with a series of related nitrophenyl compounds was investigated. The failure of trinitrophenyl (TNP)-sensitized effector cells to lyse TNP-beta-alanylglycylglycyl(AGG)-modified target cells is presented as evidence contradicting the intimacy or dual receptor model or T-cell recognition in its simplest form. Data are also shown indicating that sensitization with N-(3-nitro-4-hydroxy-5-iodophenylacetyl)-AGG-modified stimulating cells generates noncross-reacting clones of cytotoxic effector cells.

摘要

研究了用一系列相关硝基苯基化合物修饰的自体脾细胞进行体外致敏所产生的C57BL / 10细胞毒性效应细胞的特异性。三硝基苯基(TNP)致敏的效应细胞不能裂解TNP-β-丙氨酰甘氨酰甘氨酰(AGG)修饰的靶细胞,这一结果被作为与最简单形式的T细胞识别的紧密性或双受体模型相矛盾的证据。还显示的数据表明,用N-(3-硝基-4-羟基-5-碘苯基乙酰基)-AGG修饰的刺激细胞致敏可产生细胞毒性效应细胞的非交叉反应克隆。
