| | CD4-Positive T cells in Bacterial Killing |
 | | In certain disease conditions, most notably in sarcoidosis, this skin test reactivity to a range of common recall antigens is lost. | | | There are distinct pathways of processing of antigen for presentation in association with class I and class II MHC molecules. | | | The loss of responsiveness is known as immunological "anergy", and may be specific for a particular antigen / organism (eg for PPD in miliary tuberculosis) or more generalised (as in sarcoidosis). |

| | Lymphocytes |
| | Memory lymphocytes form the basis for strong secondary immune responses | | | Positive selection means enhancing development of certain T lymphocytes | | | Lymphocytes can develop into long-lived cells which "remember" a previously encountered antigen; these are called memory lymphocytes |

| | Lymphocyte.net: Information about lymphocytes |
| | T lymphocytes are found in peripheral lymphoid organs and are responsible for cell mediated immunity. | | | Lymphocytes are found in circulating blood, the thymus, spleen, lymph nodes and other lymph organs. | | | T cells are responsible for cell-mediated immune responses to intracellular parasites, viruses, fungi and bacteria. |

| | Eventually the patient dies of these opportunistic infections. | | | Not only does the patient become hypersusceptible to pathogens that give all of us grief but also to microorganisms, especially viruses and fungi, that normally inhabit our tissues without harming us. | | | T cells drops below 400 per microliter, the ability of the patient to mount an immune response declines dangerously. |

| | Definition of "T lymphocytes (T-cells)" |
| | T lymphocytes are also important in the body's defense against cancer. | | | They are important in the body's defense against certain bacteria and fungi, aiding B lymphocytes in making antibodies, and helping in the recognition and rejection of foreign tissues. | | | White blood cells that are produced in the bone marrow but mature in the thymus. |

| | Treatment of cancer using surgery, usually to remove cancerous tumors and tissue. | | | A small lymphocyte, made in the bone marrow, that circulates through the bloodstream. | | | In a type of experimental therapy, scientists harvest these cells from the tumor, grow them in a laboratory,and then return them to the patient with the hope of the cells destroying the tumor. |

| | T lymphocytes |
| | This may be a macrophage with exposed antigen or a body cell that has been invaded by a pathogen and is displaying antigens on plasma membrane as a help signal. | | | Lymphocytes are smaller than phagocytes and their nucleus fills most of the cell. | | | Have specific surface cell receptors (T cell receptors) which have similar structure to antibodies and are specific to one antigen. |

| | We have found that superantigen stimulation results in different effector functions than Ag/MHC stimulation and we hypothesize that this may be the consequence of differential intracellular signaling events. | | | My research involves the study of anti-influenza T lymphocyte clones, their antigen specificity, role in protection and recovery | | | Vivian Lam Braciale, Ph.D. Vivian Lam Braciale, Ph.D. "My research involves the study of events in T lymphocyte activation, using cloned antiviral T cells. |

| | The Immune System - Symptoms, Treatment and Prevention |
| | Most healthy cells are of no interest to natural killer cells, but cancer cells and cells invaded by viruses may be vulnerable to their search and destroy missions. | | | The T lymphocytes (T stands for thymus-derived) have various functions, including switching on various aspects of the immune response, and then (equally important) switching them off. | | | Another class of lymphocyte cells is called "natural" because, unlike T and B cells, it does not need to be triggered by a specific antigen. |

| | Cytotoxic T Lymphocyte |
| | Cytotoxic T lymphocytes (CTL) recognize surface markers on other cells in the body that label those cells for destruction. | | | In this way, CTLs help to keep virus-infected or malignant cells in check. | | | A longer, larger version of the above clip may be purchased and downloaded for classroom use as part of the "Immune System Collection". |
