在过去近10年中,对NK进行了大量的研究,并已有了一个较完整的结果。但对NK杀伤靶细胞的确切机制仍不清楚。NK杀伤靶细胞的物质、作用部位及途径也有争议。近年来国外采用单个细胞细胞毒方法研究NK的杀伤机制,取得了很大的进展。这一方法是以效应细胞与靶细胞形成的结合物为对象,研究NK在杀伤过程中各个阶段上的特征及机制,能较完善地获取有关杀伤机制的信息,为深入研究NK的杀伤机制提供了有利的
In the past 10 years, a great deal of research has been done on NK and a more complete result has been obtained. However, the exact mechanism by which NK targets killer cells remains unclear. NK killer target cells, the role of site and approach are also controversial. In recent years, foreign countries using a single cytotoxic cytotoxicity of NK mechanism has made great progress. This method takes the combination of effector cells and target cells as the object to study the characteristics and mechanisms of NK in various stages of the killing process and to obtain more complete information about the killing mechanism for further study on the NK killing mechanism Favorable
