The result is a sensitive system of checks and balances that produces an immune response that is prompt, appropriate effective, and self-limiting.
At the heart of the immune system is the ability to distinguish between self and no self. When immune defenders encounter cells or organisms carrying foreign or nonself molecules,the immune troops move quickly to eliminate the intruders(入侵者). Virtually every body cell carries distinctive molecules that identify it as self. The body’s immune defenses do not normally attack tissues that carry a selfmark
