| Adaptive immunity is a complex system of defense whereby the body can recognize, recall, and most importantly attack pathogens. The system is much more different from innate immunity because it takes some time before being produced and proves to be very specific to the particular pathogen it is produced against. Its two major forms are humoral immunity and cell-mediated immunity. B-cell-mediated immunity is one of the classes of humoral immunity. These cells produce antibodies against antigens. The secreted antibodies diffuse in the various body fluids scanning for pathogens targeted for destruction by other immune cells. This is one of the best characteristics of adaptive immunity over such extracellular pathogens as bacteria and viruses. T cells initiate cell-mediated immunity. They do not produce antibodies but kill the infected cells directly. Helper T cells, or Th cells, amplify the response of the immune system through secreted cytokines that enhance the activity of other cells of the immune system. Cytotoxic T cells, or Tc cells, kill the infected cells once they recognize small parts of pathogens, antigens presented on those cells. The adaptive immune system has immunological memory too. It defends and is much more effective should the same pathogen enter your body again after initial exposure to it. This is the science behind vaccination-exposure to a harmless form of a pathogen to stimulate memory cells without producing the disease itself. Long-term protection from infections-this is the gold reserve of adaptive immunity, but its memory is the powerful stimulus in the whole effect of vaccines and immunotherapies. |
