ABSTRACT
Objective:
To study the effects of IL-2 and IL-15 on the expression of NKG2D and the cytotoxicity of edited-NK cells against human nasopharyngeal carcinoma cell line CNE2.Methods:
NK cells were purified by anti-CD56 MACS and were divided into four groups non-edited-NK cells group(NK cells treated with 100 U/ml IL-2),edited-NK cells group(NK cells co-cultured with CNE2 cells at a ratio of 10∶1 and then treated with 100 U/ml IL-2),edited-NK cells retreated with 1 000 U/ml IL-2 group,and edited-NK cells retreated with 10 ng/ml IL-15 group.Expression of NKG2D in each group was determined by FACS 24 h later.Cytotoxicity of NK cells against CNE2 cells(NK∶CNE2 being 20∶1) was measured by LDH releasing assay.Results:
The expression of NKG2D in non-edited-NK cells,edited-NK cells,edited-NK cells retreated with IL-2,and edited-NK cells retreated with IL-15 were(97.63?0.83)%,(53.50?1.25)%,(94.47?1.00)%,and(98.07?0.21)%,respectively.The expression of NKG2D on edited-NK cells retreated with IL-2 or IL-15 was significantly increased than that on edited-NK cells(P
