The T cells destroy the body's own cells that have themselves been taken over by viruses or become . Binding of antibody inactivates viruses and microbial toxins (such as tetanus toxin or diphtheria toxin) by blocking their ability to bind to receptors on host cells. Like all connective tissues, it is made up of cellular elements and an extracellular matrix. Antibodies, also known as immunoglobulins (Ig), are large, Y-shaped glycoproteins produced by B-cells as a primary immune defense. Antigen binding by antibodies is the primary function of antibodies and can result in protection of the host. Definition. There are two main types of lymphocytes: B cells and T cells.
