| Abstract: | The methodological aspects of Lak-cells functional activity test were determined. NK-resistance of P-815 culture cells and NK-sensitive K-562 cells were used as target cells. The highest cytotoxicity level was registered at the 5-th day of culturing MNC with rIL-2 at the final concentration (100 U/ml). The method developed was used for testing healthy donors group and group of patients with IL-2 dependent immunodeficiency (ophthalmic herpes). Data obtained show the significant decrease of LAK-cells functional activity of patients in comparison with healthy donors. Thus, the developed method is recommended for complex estimation of immune status of patients with IL-2-dependent immuno deficiency. |
