Antibodies Cellular

Cellular antibodies are specific proteins that are produced by the body's immune system in response to an antigen load. They play an important role in protecting the body from infections and other pathogens.

Cellular antibodies are collections of molecules called immunoglobulins that bind to antigens (foreign substances) on the surface of cells. These antigens may be bacteria, viruses, parasites, or other foreign organisms.

An antibody consists of two main components: a heavy chain and a light chain. The heavy chain contains most of the antigenic determinants, and the light chain ensures binding of the antibody to Fc receptors on the surface of phagocyte cells.

One of the important properties of cellular antibodies is their ability to activate complement, which leads to the destruction of foreign cells. Complement consists of a number of proteins that are activated upon binding to an antibody, resulting in the formation of an antigen-antibody complex.

In addition, cellular antibodies can be used as diagnostic tools to determine the presence of antigens in the body. For example, tests for HIV infection use antibodies to detect the virus in the blood.

Thus, cellular antibodies play an important role in the body's immune response to antigens and are a key element in protection against infections.

Cellular antibodies are a special type of antibody that is formed in the human immune system in response to antigens. These cells have a shape and structure that helps them perform their functions by interacting with various cells and tissues of the body.
