Infusion of normal recipient mice with suppressor T cells from donors bearing a progressive Meth A fibrosarcoma results in a diminished capacity of the recipients to generate concomitant and postexcision antitumor immunity. The passive transfer of suppressor cells which prevented the generation of immunity to the Meth A fibrosarcoma did not affect the capacity of the recipients to reject an allogeneic tumor. The data provides direct evidence in support of the hypothesis that suppressor T cells, generated at later stages of growth of Meth A fibrosarcoma, function to down-regulate an already acquired mechanism of concomitant immunity.
给正常受体小鼠输注来自患有进行性Meth A纤维肉瘤供体的抑制性T细胞,会导致受体产生伴随性和切除后抗肿瘤免疫的能力下降。抑制性细胞的被动转移阻止了对Meth A纤维肉瘤免疫的产生,但不影响受体排斥同种异体肿瘤的能力。这些数据提供了直接证据,支持以下假设:在Meth A纤维肉瘤生长后期产生的抑制性T细胞,其功能是下调已经获得的伴随免疫机制。
