摘要
多数学者认为,NK细胞与K细胞是同一类细胞,或同一类细胞的不同分化阶段,但是,二者在带瘤动物和肿瘤病人体内上表现的功能不同,即NK细胞功能往往低下,而K细胞功能往往正常或增高。什么原因造成这一功能上的不同,本文对这个问题进行了初步研究。
The dynamic activity of NK and K cells in P388 tumor bearing DBA/2 mice wastested and compared. It was found that the dynamic curve of NK activity was usuallybelow and that of K cell activity was above the standard level in normal mice. The Kcell activity curve was quite comparable to the curve of LGL number in spleen. Thedepressed NK activity was supposed to be due to the inhibitory factors secretedprobably by tumor cells, and K cells may have been spared.
