The effect of lymphocytes from normal mice on the growth of a syngeneic, radiation-induced, T-cell-derived lymphoma was investigated. Thymus and spleen cells enhanced the growth of admixed lymphoma cells in a reproducible manner. Growth enhancement was manifested by the earlier appearance and higher final incidence of tumours. Lymphocytes also enhanced the growth of radiation-damaged lymphoma cells. The enhancing activity of spleen cells was predominantly a property of T cells, since it was abolished by treatment with anti-theta serum plus complement and significantly less in spleen cells of nude mice. Tumour-enhancing thymocytes seem to belong to the immature thymic subpopulation, as indicated by their binding to peanut agglutinin.
研究了正常小鼠淋巴细胞对同基因、辐射诱导的T细胞源性淋巴瘤生长的影响。胸腺细胞和脾细胞以可重复的方式促进了混合淋巴瘤细胞的生长。生长促进表现为肿瘤出现更早且最终发病率更高。淋巴细胞还促进了受辐射损伤的淋巴瘤细胞的生长。脾细胞的增强活性主要是T细胞的特性,因为用抗θ血清加补体处理可消除该活性,且裸鼠脾细胞中的活性明显较低。肿瘤增强性胸腺细胞似乎属于未成熟胸腺亚群,这可通过它们与花生凝集素的结合来表明。
