The process of agglutination combines antigens and antibodies. It is the basic biological process that the body uses to defend itself against various foreign particles like viruses and their toxic chemicals. An antigen-antibody complex is formed in the blood when antibodies specifically and strongly bind to antigens. The immunological complex is subsequently transferred to cellular systems where it can be eliminated or deactivated.

Antigens and antibodies play vital but distinct roles in illness and disease. One tries to wreak havoc on our health while the other fights to protect it. Simply put, antigens can make you sick, and antibodies are how your body defends itself against antigens. Read on to find out the important role antigens and antibodies play in your health and how they do it. Antigens, or immunogens, are substances or toxins in your blood that trigger your body to fight them. Antigens are usually bacteria or viruses, but they can be other substances from outside your body that threaten your health. This battle is called an The presence of antigens rouses your body’s illness-fighting white blood cells, called There are two main types of antigens, heteroantigens and autoantigens: • Heteroantigens are substances that are foreign to your body and involve substances made by or found within: • viruses • bacteria • protozoa • blood and red blood cells from other people • snake venom • allergens such as pollen • certain proteins in foods • Autoantigens, or self-antigens, are made by your body to fight your cells and are usually a sign of an illness such as an autoimmune condition. Antibodies are also called immunoglobulins or Ig. They are Y-shaped proteins made by your immune system’s B lymphocytes or B cells. B cells attack and eliminate viruses and other toxins outside the cell. They do this by making specific antibodies for a single type of antigen. These tailored antibodies lock on to their ...
