IMMUNE SYSTEM AND INFLAMMATION: T CELLS, В CELLS AND ANTIBODIES
What are T cells?
T cell stands for thymus-derived lymphocyte. There are several varieties of T cells. Some (called the helper T cells) help immune function by telling the В cells to begin producing antibodies to fight off antigens. Suppressor T cells turn off immune function. Killer T cells (also called cytotoxic T cells) directly recognize, attack, and destroy antigens.
What are В cells?
В cells are very specialized lymphocytes that are responsible for a variety of functions. Their major role is that they eventually develop into cells called plasma cells, which make antibodies. The В cells got their names from a gland in chickens, called the bursa of Fabricius, where they were first discovered.
How does the immune system produce antibodies?
While the immune system produces antibodies as a response to antigens, it begins their production shortly before birth. While the antibodies of the fetus are limited in both type and number, there is evidence that they are produced in large amounts.
If a person is exposed to an antigen that is not recognized as self, his or her immune system rejects it as foreign. This process of recognition goes on every second during a person’s life. When an individual becomes infected with any organism an immune response results. After the immune response is made, a permanent memory is created in the immune system. One of the more fascinating things about the immune system is its ability to remember. As far as we currently know, there’s only one other component of the body that can remember things-the brain.
The B cells are responsible for making the antibodies. They can be stimulated to make these proteins either directly by a foreign substance or by the T cells. When the В cells make an antibody in direct response to an antigen, it is called a T-independent response. When the T cells stimulate the В cells to make more antibodies, it is called a T-dependent response.
