[Cytolytic action of normal human natural killer cells on CNE-2 nasopharyngeal carcinoma cell in vitro].
Cytolytic actions of human natural killer cells, which were separated with nylon wool column from normal human peripheral blood, were investigated on human nasopharyngeal carcinoma cell line cells (CNE-2) and the dynamic processes of conjugation and cytolysis were studied. It was found that NK cells attacked living target cells and the course of cytolysis might be divided into 2 types according to their rapid or slow responses. In addition to the large granular lymphocytes the non-granular lymphocytes also participated in NK functions.
