What is a protein antigen?
Protein antigen is a protein that can stimulate the production of antibodies by the immune system and to which the immune system will respond if it is identified in the body. Antigens can be made of a series of compounds, with protein antigens are among the most common. Scientists who are interested in the immune system and the disease process have been identified in research, diagnosis and medical treatment by numerous protein antigens.
Exogenic protein antigen is a protein produced outside the body by another organism and antigens by another organism. An example is a protein created by a virus that someone enjoys. When the immune system sees this protein, it recognizes it as foreign and stimulates the production of antibodies that can capture and attack antigen. This is one of the defense lines of the body against disease agents. Endogenic protein antigens are produced in the body. They are very often seen in cell death. Cells incarnate can be programmed to make these antigens so that the immune system knows when it is time robeat the cell and recycle its components. This type of protein antigen can also be used to indicate infected cells for destruction.
Another type of protein antigen is self -enabled. Autoantigens are substances that usually occur in the body and are usually seen as harmless, which the body begins to identify as an antigen. Autoantigens are involved in an autoimmune disease in which the body begins to attack because the programming of the immune system is frightened. In this case, the protein, which is actually part of the body, is considered to be a malicious immune system and the immune system strives to remove it, even if it can cause body injury.
vaccination may include controlled introduction of antigen, often protein antigen, the body that allowed him to create antibodies without exposing the risk of disease. Antigens can also be used in TEStech; If the doctor suspects that the patient has a specific virus, the blood sample may be introduced into the selection of antigens to find out which antigens are binding to. Identification of antigens may also be important for blood tests to determine whether they are some resistant to illness or whether someone has been exposed to illness.
