Compared with classical cytotoxic T lymphocytes , NK cells are superior in the following aspects: NK cells are among the first cell types to be activated after intracellular pathogen stimuli, the activity of NK cells peaked between 1 to 3 days, retained during the first 7-10 days, and the T cells response emerged only after 7 days when the NK cell responses begin to decline; though comprising of only 10%-15% of peripheral lymphocytes, NK cells mobilize most of the cell populations in a strong and high level response to different invasions, and act as key factors at early defense before a specific immune response could mount, while only certain clones were involved in T cell response; NK cells kill virus-infected or malignant transformed cells without pre-sensitization and without restriction by major histocompatibility antigen, which is usually a mechanism of immune escape to T cell recognition by virus-infected or tumor cells, thus NK cell in complementary with T cells play crucial roles in tumor and virus eradication.

NK细胞以其强大的细胞毒活性为特征,与细胞毒性T细胞相比,NK细胞具有如下特点:NK细胞虽然只占外周血淋巴细胞的10-15%,但是对刺激性因素产生应答的过程十分迅速,一次可以调动大多数细胞共同参与,而不是几个克隆的活化,免疫应答的强度高;病毒感染或恶性转化细胞的一个主要特征是细胞表达的MHCⅠ类分子下降或消失,并借助这一机制逃避特异性T细胞应答的识别,NK细胞介导的杀伤活性无需抗原刺激,不受MHCⅠ分子表达的限制,从而与T细胞应答互为补充发挥免疫防御的功能;NK细胞的免疫活性可以被多种细胞因子上调,其中IFNα,IL-2,IL-12,IL-15和IL-18具备更强的作用;NK细胞具有强大的细胞因子分泌功能,对于启动T细胞特异性应答必不可少。
