…than antibodies, it is called cell-mediated immunity. T cells recognize only infectious agents that have entered into cells of the body, whereas B cells and antibodies interact with invaders that remain outside the body’s cells. These two types of specific, acquired immunity, however, are not as distinct as might be…

In addition to their importance in cooperating with B cells that secrete specific antibodies, T cells have important, separate roles in protecting against antigens that have escaped or bypassed antibody defenses. Immunologists have long recognized that antibodies do not necessarily protect against…

As has been stated, cellular immunity is mediated by T lymphocytes that can recognize infected body cells, cancer cells, and the cells of a foreign transplant. The control of cellular immune reactions is provided by a linked group of genes, known as the…

In cellular immunity, a killer T cell recognizes and kills a virus-infected cell because of the viral antigen on its surface, thus aborting the infection because a virus will not grow within a dead cell. If the virus-infected cells are not essential for host functions, the…

…second type of response, called cell-mediated immunity, does not yield antibodies but instead generates T lymphocytes that are reactive against specific antigens. This defense is exhibited against bacteria and viruses that have been taken up by the host’s cell as well as against fungi, transplanted tissue, and cancer cells. In…

cell-mediated immunity, so named because the T cells themselves latch onto the antigens of the invader and then initiate reactions that lead to the destruction of the nonself matter. B lymphocytes, on the other hand, do not directly attack invaders. Rather, they produce antibodies, proteins…
