| | Lymphocytes and the Cellular Basis of Adaptive Immunity |
 | | Lymphocytes are responsible for the astonishing specificity of adaptive immune responses. | | | We shall see that each lymphocyte is committed to respond to a specific antigen and that its response during its first encounter with an antigen ensures that a more rapid and effective response occurs on subsequent encounters with the same antigen. | | | Only lymphocytes restored the adaptive immune responses of irradiated animals, indicating that lymphocytes are required for these responses (Figure 24-4). |

| | Lymphocytes |
| | Lymphocytes are produced within bone marrow (a primary lymphoid organ). | | | These have many actions, including control of the adaptive immune response by secondary action on the participating cells, and, in the case of cytolytic T cells, in killing virally-infected host cells. | | | If they achieve immune-competence within the bone marrow, they are known as B cells, or if in the thymus (also a primary lymphoid organ), they are known as T cells. |

| | Lymphocytes are small cells with virtually no cytoplasm, found in the blood, in all tissue and in lymphoid organs, such as lymph nodes, the tonsils, thymus gland, spleen and Peyer's patches. | | | Among other functions, natural killer cells destroy cancer cells and virus-infected cells through phagocytosis and by producing substances that can kill such cells. | | | Lymphocytes identify foreign substances and germs (bacteria or viruses) in the body and produce antibodies and cells that specifically target them. |
