免疫学重点（Immunology focus） The modern concept of immunity: immune system recognition (discrimination) self components (self, self) and other substances (I, non-self), produced a series of specific responses, finally remove foreign bodies, the formation of tolerance to self organization, with a kind of physiological function to maintain the stability of the environment. The definition given by the teacher: the ability of the organism to recognize and remove foreign bodies and maintain the normal physiological functions of the organism. 2., immune function: immune function is the immune system in the identification and removal of non self antigen in the process of producing a variety of biological effects of the general term. Mainly include: Immune defense (Immunologic defence): it is an immune protective function that the organism repels foreign antigenic foreign bodies. When normal, can produce the effect of anti infection immunity, the defense function is too strong will produce hypersensitivity reaction, too weak will produce immunodeficiency (the latter two cases are abnormal reaction). Immune homeostasis (immunologic, homeostasis): the immune system maintains a relatively stable physiological environment. Normal: the body clears the damaged, senescent and denatured blood cells and antigen antibody complexes in time to maintain immune tolerance to their own components; Abnormalities: disorders of physiology, autoimmune diseases, etc.. Immunologic surveillance (immune surveillance): the immune system is a timely identification, removal of mutations and aberrations in the body, and viruses interfere with the cells of a physiological role. Loss: loss of the bodys mutant cells, potentially causing tumors, or a persistent infection of the virus. The concept of medical immunology: is the study of the human immune system composition and function, immune response, immune function rules and effects caused by the abnormal disease and its pathogenesis, immunology and diagnosis
