Why don't natural killer cells destroy normal body cells?

Answer 1

Why do NK cells not kill RBC?
The “self” MHC receptors of cells would normally act as an inhibitor. When a cell (such as red blood cell) gets infected, the pathogen's receptor (antigen) will tend to act as an activating receptor on NK cells. ... So unless RBC sends a signal telling NK cells to act on them, it won't kill them.
