How the Host Avoids "Friendly Fire"

Summary

Normally the trillions of lymphocytes in the human body do not attack their host. 

Normally the trillions of lymphocytes in the human body do not attack their host.

Cells that escape this screen treat host molecules as invaders, causing serious autoimmune (self-destructive) diseases such as juvenile diabetes, rheumatoid arthritis, and lupus erythematosis.
