What is the difference between antigens and antibodies?

antigens and antibodies are basically in the war among themselves in most human bodies. Antibodies, also known as immunoglobulins, are Y -shaped molecules found in the blood that fight strangers known as antigens. Antigens are proteins or polysaccharides of bacteria, chemicals or virus that attack the immune system. They can also cause allergic reactions due to beam, food or pollen. For example, if a patient receives a blood transfusion and his body treats new blood as a foreign substance, antibodies can seriously attack the immune system. In organ transplants, the immune system could be rejected by the transplant tissue cell. In both examples, this could lead to great infection or even death.

Not all foreign antigens are environmental. For example, cancer cells are antigens that develop in the body. If the immune system is unable to destroy or destroy these cancer cells, they could multiply millions and seriously attack the immune system. AndTigens and antibodies fight each other for mere survival of the human body. B cells are white blood cells found in bone marrow stem cells. Finally, they develop on plasma cells that produce antibodies.

In order to attack the most common antigens found in the body, the Y -shaped molecules allow different antibodies attached to different antigens. The Y-shaped molecules are locked on the key to the antigen and then wrap around the antigen until the antigen is destroyed and the antibodies are in some sense mortal enemies.

At the ends of Y -shaped molecules are amino acids. Amino acids are that that is to help antibodies recognize the presence of antigens. Each antibody is created to match most antigens. Antigens and antibodies are numerous in the body - the body's immune system is able to record and destroy more than a million different antigens.

There are five different antibodies classes: IgA, IgD, IGE, IgG, Igm. IgA antibodies usually occur in mucus, saliva and tears. IGD antibodies are found in tissue lining of the abdomen and chest, but it is not entirely clear what their main function is. IgE antibodies release histamines against such foreign substances such as pollen, food, hay fever and asthma.

IgG antibodies are the most common and widespread antibody. It protects the immune system from main infections and diseases. They also move between cells and blood to protect organs and skin. IGM antibodies are the first antibodies that move against any type of bacterial, chemical, fungal or viral attack.
