Summary Introduction
To review:
Cytokine and the functions of CTL, TH1 and Treg.
Introduction:
The main function of immune system is to protect against the invasion of foreign substance or infectious materials. The immune system responds in two ways, one is nonspecific or innate and another one is specific or adaptive. Antibodies and lymphocytes are the major elements in the adaptive immune system. The lymphocytes consist of B cells, cytotoxic T cells and Helper T cells which involved in the adaptive immune response against the infectious pathogens.

In anti- body-mediated immunity, B lymphocytes may produce antibodies that react with specific antigens on an invading cell or molecule. In cell-mediated immunity, T lymphocytes secrete lymphokines that signal other immune responses and often destroy antigen- containing cells directly. The antibody-antigen reactions associated with immune responses have been used by clinical biologists for years. Several examples are given. Think about each example and answer the questions. 1. Biologists often use antibodies to test for the presence of certain antigens in a particular substance.
