The immune system is dynamic and reactive. It is a system that distinguishes self from non‐self and deletes, inactivates or supresses foreign invaders and distinguishes irreparable or altered tissue from normal, to maintain homeostasis. Where effective surveillance fails, infection or neoplasia can develop. Where active components become misdirected, autoimmune disease can follow. It is assumed that the reader has a basic understanding of the immune system and its components, the cytokine network and their interactions.
