Introduction to Immunology

Le résumé fourni par la source

In this chapter, the authors present the historical attributes of immunology along with a brief introduction to pathways used by their body for the recognition and respond to foreign invaders and to discriminate between self and non-self. The study of Immunology stemmed out from the Thucydides’ description of individuals who recovered from the plague in Athens. The immunoglobulin genes, and the genes that make up the T-cell antigen receptor undergo somatic rearrangements to account for the immunological diversity. Exposure to a foreign substance leads to the recruitment of a variety of cells and signal molecules called “effector” in our body to destroy/neutralize that invader. Innate is a broad, less specific, and more primitive immune system that provides the first line of defense against foreign invaders during first encounter. Adaptive immunity is highly advanced and more specific type of immunity with a remarkable property of inducing “memory” response on second exposure to some antigen, and the ability to self/non-self recognition.
