Immunology is a major branch of biomedicine that explores the immune response produced in various organs. It mainly discusses the physiological function of the immune system in health or illness; some diseases caused by immune system diseases (such as autoimmune reaction, allergic reaction, immune dysfunction); in vivo or in vitro (in In vitro) The immune system constitutes the physical, chemical, and physiological properties of a molecule.
Immunization refers to a physiological function in which the body recognizes "self" and "non-self" antigens, forms the natural immune tolerance to autoantigens, and produces the rejection of "non-self" antigens. Under normal circumstances, this physiological function is beneficial to the body, and can produce anti-infective, anti-tumor and other physiological balance and stable immune protection. Under certain conditions, when the immune function is dysfunctional, it will also have harmful reactions and results to the body, such as triggering hypersensitivity reactions, autoimmune diseases and tumors.
Modern immunology believes that the immune function of the body is a response to antigenic stimulation, and the immune response is manifested by the ability of the immune system to identify itself and exclude others. Immune function plays a role in immune recognition. This function is rough: immune defense of exogenous foreign bodies (mainly infectious agents); removal of immune from decay or damage to cells to maintain their own stability; elimination of immune surveillance of mutant cells.
Only when the immune system plays its role under normal conditions and maintains a relative balance can the body survive. If the immune function is abnormal, it will inevitably lead to the imbalance of the body's body and immunopathological changes.
Immune function is a general term for various biological effects produced by the immune system in the process of identifying and eliminating "non-self" antigens. mainly include:
1. Immune defense
It is an immune protection function that the body rejects foreign antigenic foreign bodies. Normally, it can produce anti-infective immunity. If the defense function is too strong, it will produce a hypersensitivity reaction. If it is too weak, it will produce immunodeficiency (the latter two cases are abnormal reactions).
2. Immune self-stabilization
It is a physiological function that the body's immune system maintains a relatively stable internal environment.
Normal: The body can remove the damaged, aging, degenerated blood cells and antigen-antibody complexes in time, and maintain immune tolerance to its own components.
When abnormal: physiological dysfunction, autoimmune disease, etc. occur.
3. Immune surveillance
It is a physiological protective effect of the body's immune system to identify and eliminate in vivo mutations, aberrations and virus interference.
Loss: The body's mutant cells are out of control, which may lead to tumors; or a persistent infection of the virus.
The immunology major is an unpopular major. The graduates of this major mainly go to the Food and Drug Administration, the Inspection and Quarantine Bureau to carry out related work, and then go to higher education institutions and research institutes to engage in related teaching and research work.
