Question

Quizplus · Accepted Answer

Natural killer cells recognize and kill target cells lacking expression of HLA-A, B, and C. This is because the presence of HLA molecules on the surface of target cells signals to other immune cells that they are self-cells and should not be attacked. Cells that do not express HLA molecules, which can occur in some tumor cells or infected cells, can be recognized and killed by natural killer cells.
