不少学者报告人类某些恶性肿瘤中的单个核细胞浸润(mononuclear cell infiltration)与预后呈阳性联系,浸润高度者预后常较好,然而对于浸润细胞的类型及它们的分布状况却很少研究。在肿瘤免疫研究方面一般认为T细胞介导的细胞性免疫在实体瘤的排斥中起主要作用,但在宿主体内针对肿瘤的细胞性免疫究竟如何进行,何以带瘤宿主的淋巴细 Many scholars have reported a positive relationship between mononuclear cell infiltration and prognosis in some human malignancies. Infiltrative individuals have a better prognosis, but few studies have examined the type of infiltrating cells and their distribution. In the field of tumor immunity research, T cell-mediated cellular immunity is generally considered to play a major role in the rejection of solid tumors. However, how is the cellular immunity of the tumor to be carried out in the host body?
