a type of white blood cell that matures in the thymus and carries out the cell-mediated immune response. Three major types of T-cells are helper (CD4) T-cells, suppressor (CD8) T-cells, and killer (CD8) T-cells (cytotoxic T-lymphocytes or CTLs). Contrast with B-cell.
lymphocyte "born" in the thymus
T-cells received their name from the “t” in thymus, a gland in the chest that shrinks and disappears as people grow into adulthood. These cells are critical to a variety of immune functions. Uncontrolled proliferation after the malignant transformation of this type of cell gives rise to T-cell lymphoma.
a type of white blood cell derived from the thymus that participates in a variety of cell-mediated immune responses. There are 3 major types of T-cells: T-helper (CD4), T-suppressor (CD8) and T-killer (cytotoxic T-lymphocytes or CTL).
Any lymphocyte that matures in the thymus.
T-cells are a type of white blood cell which are normally very effective at defending the body against disease but occasionally they start attacking the body's own tissue as in rheumatoid arthritis.
A type of white blood cell that is part of the immune system and normally helps protect the body against infection and disease. In psoriasis, it also can trigger inflammation and excessive skin cell reproduction.
a type of white blood cell and an important part of the immune system. They lead the attack against infections and kill cancer cells and cells infected with a virus.

A white blood cell concerned with immunity. It does not produce antibodies.
One of two main types of white blood cells critical to the immune system. They include CD4+ and CD8+ T-cells. The "T" stands for the thymus, where T-lymphocytes mature. (See lymphocyte.)
a form of white blood cell that helps the body fight disease
a white blood cell or lymphocye found in blood
a white blood cell that helps B-cells make antibody, kills other cells and suppresses immune reactions
T-cells or T-lymphocytes are very important for immunity. They are formed in the thymus gland and react highly specifically against the particular type of antigen that initiated their development.
A class of lymphocyte that mounts a cell-mediated immune response against an antigen. The body has different classes of T-cells, such as cytotoxic (killer), memory, helper, and suppresser T-cells.
Type of lymphocyte; target cell of HIV.
A small lymphocyte, made in the bone marrow, that circulates through the bloodstream. T-cells have several functions, and are especially important in the body's immune response.
One of the groups of immune cells (lymphocytes).
A class of white blood cells of the immune system that interact to produce the 'cellular' immune response. Mature T-cells can be divided into two major subsets, "CD4+" and "CD8+" that differ in function. 'Killer' T-cells (a subset of "CD8+") directly attack and kill cells bearing foreign antigens (See T-lymphocytes).
this is another name for a CD4-lymphocyte (see above)
A white blood cell involved in controlling immune reactions and fighting viral infections.
a white blood cell derived from the thymus that contributes to the cell-mediated immune response. There are 3 major types of T-cells: T-helper (CD4 cells), T-suppressor (CD8 cells) and T-killer (cytotoxic T-lymphocytes or CTL). Contrast with B-cell.
A form of immune cell that mediates humoral and cellular immune responses.
it is a lymphocyte that helps fight infection. It originates in the bone marrow and need macrophages to help identify the "non-self" antigen before it responds.
A type of lymphocyte responsible for attacking and destroying virus-infected cells, foreign tissue and tumor cells. Cytotoxic T- cells target a particular antigen and secrete toxic chemicals to kill the foreign cell or tissue. Other T-cells, called Helper T-cells, activate lymphocytes like B- cells and NK cells to help the body fight off invading viruses, micro- organisms and malignant cells.
A type of white blood cell whose activities are influenced by the thymus gland. - Are responsible for cell-mediated immune responses used to fight virual infections. (Also See: Lymphocytes) - A white blood cell (Lymphocyte) that dominates the immune response to an antigen.
A small lymphocyte, made in the thymus, that circulates through the bloodstream. T-cells play a role in the body's immune system .
An immune system cell or lymphocyte that directs an immune response to malignant or infected cells.
A type of white blood cell that is of key importance to the immune system and is at the core of adaptive immunity, the system that tailors the body's immune response to specific pathogens. The T-cells are like soldiers who search out and destroy the targeted invaders.
See in this glossary " Lymphocyte".
an immune system cell that produces substances called cytokines, which stimulate the immune response. thoracic - the part of the spine at the upper-back to mid-back level.
A type of white blood cell that attacks virus-infected cells, foreign cells, and cancer cells. T cells also produce a number of substances that regulate the immune response. T-cells are also known as lymphocytes.
Thymus dependent lymphocyte.
A white blood cell that works as part of the immune system in the body.
a type of lymphocyte. T cells have T-cell receptors and, sometimes, co-stimulatory molecules on their cell surfaces. The T cell helps to orchestrate the immune system and can issue "orders" for other cells to make cytokines and chemokines.
A type of white blood cell essential to the body's immune system. Helps regulate the immune system and control the functions of other types of white blood cells.
Lymphocyte derived from bone marrow stem cells that matures into an immunologically competent cell under the influence of the thymus. Involved in cell-mediated immune reactions.
(T lymphocyte) Type of lymphocyte responsible for cell-mediated immunity; includes both cytotixic T cells and helper T cells
A type of lymphocyte that recognizes and destroys foreign antigens (enzymes, toxins, or other substances) and thus plays an important role in the body?s immune response.
A blood cell originating from bone marrow which matures in the thymus. Some T-cells are responsible for cell-mandated immunity and the production of antibodies.
T cells are lymphocytes that are produced in the bone marrow and mature in the thymus. T cells are responsible for mediating the second branch of the immune system called "cellular immune response." T cells can live for months to years. This lymphocyte population is defined by the presence of a rearranged T-cell receptor.

An immune-system cell that orchestrates an immune response to infected or malignant cells, sometimes by direct contact with the abnormal cells; T-cells are lymphocytes that develop in the thymus and circulate in the blood and lymphatic system; see dendritic cell.
