Abstract

Two types of thymus-derived (T) lymphocytes have been shown to cooperate in the induction of graft-versus-host responses. One cell type is found in highest concentrations in the peripheral blood and lymph node, is extremely sensitive to anti-thymocyte serum (ATS) in vivo, and is probably part of the recirculating lymphoid cell pool (3). The second cell type, found in highest concentrations in the thymus and spleen, is relatively resistant to small doses of ATS in vivo. Both cell types are substantially depleted after neonatal thymectomy. Moreover, since synergism was also obtained using appropriate mixtures of cells from either parental strain in F(1) hosts, it was possible to show that the nonrecirculating cells determined the specificity of the response and were probably the precursors of effector cells in this response. The recirculating T cell appeared to amplify this response. The implications of these data are discussed.

摘要

已证明两种胸腺来源的(T)淋巴细胞在移植物抗宿主反应的诱导中协同作用。一种细胞类型在外周血和淋巴结中浓度最高,在体内对抗胸腺细胞血清(ATS)极为敏感,可能是循环淋巴样细胞池的一部分(3)。第二种细胞类型在胸腺和脾脏中浓度最高,在体内对小剂量ATS相对抗性。两种细胞类型在新生期胸腺切除后均大量减少。此外,由于在F(1)宿主中使用来自任一亲本菌株的细胞的适当混合物也获得了协同作用,因此有可能表明非循环细胞决定了反应的特异性,并且可能是该反应中效应细胞的前体。循环T细胞似乎放大了这种反应。讨论了这些数据的意义。
