Abstract

T cells from strains responder to the antigen poly(Glu40 Ala60) (GA) were depleted of alloreactive cells by bromo-deoxyuridine and light treatment, and were subsequently primed in vitro in GA presented by allogeneic macrophages from nonresponder strains. Antigen-specific secondary proliferative responses restricted by allogeneic Ia molecules of the macrophages were obtained in all strain combinations tested. These data indicate that Ir gene-controlled nonresponsiveness cannot be the result of a failure of antigen presentation.

摘要

来自对抗原聚(谷氨酸40 丙氨酸60)(GA)有反应的品系的T细胞,通过溴脱氧尿苷和光照处理去除了同种反应性细胞,随后在体外由来自无反应品系的同种异体巨噬细胞呈递的GA中进行致敏。在所有测试的品系组合中,均获得了受巨噬细胞同种异体Ia分子限制的抗原特异性二次增殖反应。这些数据表明,Ir基因控制的无反应性不可能是抗原呈递失败的结果。
