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。
