Describe the body's immune system components. What are autoimmune diseases?
What will be an ideal response?
The immune response involves two major types of cells. Leukocytes, or white blood cells, recognize invaders by the unique proteins that every cell has on its surface and kill them. These proteins in foreign cells are called antigens. A type of leukocyte called a macrophage ingests intruders. Then it displays the intruder's antigens on its own cell surface; this attracts T cells, another type of leukocyte that is specific for particular antigens, which kill the invaders. B cells, a third type of leukocyte, fight intruders by producing antibodies that attack a particular cell type. Natural killer cells, the second type of immune cells, attack and destroy certain kinds of cancer cells and cells infected with viruses. Autoimmune diseases are those in which the body does not recognize self and attacks itself.
