1. NK cell trigger effector functions ( cytolysis ) by KAR, if target cell loses appropriate ligands recognized by KIR.

2. NK cell will trigger effector functions( cytolysis ) by KAR, if target cell loses appropriate ligands recognized by KIR.

3. The ultrastructure changes showed various degrees of degeneration and edema and focal cytolysis necrosis in liver, heart, lung, kidney.

4. Methods: We used virus proliferation assay cell viability assay to evaluate the proliferation and cytolysis selectivity of CNHK500.

5. Huge bite cell gobbles up fragment of deliquescent red blood cell, block Yu Xiaoliang, make Xiaoliang metamorphic, the likelihood causes cytolysis sex glaucoma.

6. Finally the virus released into the cell interval after cytolysis.

7. The soluble protein in the supernatant was separated with the precipitate after ultrasonic cytolysis and centrifugation.

8. Perforin (PFP) , a kind of glycoprotein , plays a crucial role in CTL and NK mediated cytolysis.
