[Reversible injuries of the natural killer cell membrane after contact with tumor cells].

Injuries to the normal killer membrane were studied during contact with tumor cells on isolated tumor cell-lymphocyte conjugates. The properties of the lymphocyte membrane were shown to undergo changes in the area of contact with the tumor cell membrane, manifesting in the increased membrane permeability for ribonuclease molecules. This effect was more pronounced if lymphocytes were used, in which the synthesis of RNA was suppressed.
