淋巴细胞浸润是人类许多恶性肿瘤的普遍表现,是表示预后良好的征兆。作者认为这种浸润是宿主-肿瘤关系的一个部分,但对效应细胞的本质所知甚少。胸腺依赖性细胞(T细胞)可能参与宿主对癌肿的防御,但在活体内尚未找到直接证据。本文描述了用抗人胸腺细胞 Lymphocyte infiltration is a common manifestation of many human malignancies and represents a good prognosis. The authors believe that this infiltration is part of the host-tumor relationship, but little is known about the nature of the effector cells. Thymus-dependent cells (T cells) may be involved in host defense against cancer, but no direct evidence has been found in vivo. This article describes the use of anti-human thymocytes
