Abstract

The induction of delayed-type hypersensitivity to Mycobacterium bovis BCG was specifically inhibited by suppressor T cells in C3H/He, a strain of mice which is a low responder to BCG. The existence of these suppressor cells was confirmed by an adoptive transfer of spleen cells of BCG-injected mice into cyclophosphamide-treated recipients. The suppressor cells appeared in the spleens of the mice 2 to 7 days after intravenous BCG injection. They were sensitive to anti-theta serum and complement and did not adhere to Sephadex G-10. A pretreatment of the mice with cyclophosphamide eliminated the suppression of delayed-type hypersensitivity. These suppressor cells effectively inhibited the induction of delayed-type hypersensitivity to BCG, but showed only weak effect on the expression of it.

摘要

在对卡介苗低反应的小鼠品系C3H/He中,迟发型超敏反应对牛分枝杆菌卡介苗的诱导受到抑制性T细胞的特异性抑制。将接种卡介苗小鼠的脾细胞过继转移到经环磷酰胺处理的受体中,证实了这些抑制性细胞的存在。抑制性细胞在静脉注射卡介苗后2至7天出现在小鼠脾脏中。它们对抗θ血清和补体敏感,不黏附于葡聚糖凝胶G - 10。用环磷酰胺对小鼠进行预处理可消除对迟发型超敏反应的抑制。这些抑制性细胞有效地抑制了对卡介苗迟发型超敏反应的诱导,但对其表达仅表现出微弱的影响。
