[Activity of natural killer cells in patients with testicular germ cell tumors].
The level of activity in natural killer cells (mononuclears) of peripheral blood relative to 51C-labelled K-562 cells is found to be significantly lower in patients with germinative testicle tumours than in donors. At the same time neither mononuclears of the peripheral blood nor those isolated from the tumour tissue practically lyse tumour tissue cells. The higher activity of natural killer cells relative to K-562 cells corresponds to the higher immunocellular infiltration of the tissue from nonseminomatous tumours.
