Abstract

This paper reports the localization of the regions on the beta-chain that are recognized by T cells from mice immunized with haemoglobin. The 14 overlapping peptides encompassing the entire beta-chain were examined in vitro for their ability to stimulate lymph-node cells from haemoglobin-primed B10.D2 (H-2d) and SJL (H-2s) mice. Several regions of the molecule (T sites) were found to stimulate haemoglobin-primed lymph-node cells. This strategy has enabled the localization of the full profile of T-cell recognition of the beta-chain by these mouse strains. Some of the regions that stimulated T cells appeared to coincide with those recognized by antibodies (i.e. B cells). It is noteworthy that, in addition to sites recognized by both T and B cells, the protein has other sites that are recognized exclusively by T cells and to which no detectable antibody response is directed.

摘要

本文报道了用血红蛋白免疫的小鼠T细胞所识别的β链上区域的定位。体外检测了涵盖整个β链的14个重叠肽刺激来自用血红蛋白致敏的B10.D2(H-2d)和SJL(H-2s)小鼠的淋巴结细胞的能力。发现该分子的几个区域(T位点)可刺激用血红蛋白致敏的淋巴结细胞。此策略已实现对这些小鼠品系β链T细胞识别全貌的定位。一些刺激T细胞的区域似乎与抗体(即B细胞)所识别的区域一致。值得注意的是,除了T细胞和B细胞都识别的位点外,该蛋白质还有仅被T细胞识别且未检测到抗体反应的其他位点。
