A T cell is a type of lymphocyte which developes in the thymus gland and plays a central role in the immune response. T cells can be distinguished from other lymphocytes by the presence of a T-cell receptor on the cell surface. These immune cells originate as precursor cells, ...
T cell, also called T lymphocyte, type of leukocyte (white blood cell) that is an essential part of the immune system.T cells are one of two primary types of lymphocytes—B cells being the second type—that determine the specificity of immune response to antigens (foreign substances) in the body.. T cells originate in the bone marrow and mature in the thymus.
T cell: 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.
A T cell count is a blood test that measures the number of T cells in your body. A T cell is a type of white blood cell (WBC). WBCs are also called lymphocytes. These cells fight off diseases. The ...
T-cells are part of the body's cell-mediated immunity, the part of the immune system which you can envision as directly killing bacteria, viruses, and cancer cells.The other type—humoral immunity—protects our bodies from these invaders by making antibodies.
The T helper cells (T h cells), also known as CD4 + cells, are a type of T cell that play an important role in the immune system, particularly in the adaptive immune system. They help the activity of other immune cells by releasing T cell cytokines. These cells help suppress or regulate immune responses.
T-Cell Lymphoma. T-cell A type of white blood cell that participates in immune responses by destroying harmful substances or cells. lymphomas can develop in lymphoid tissues such as the lymph nodes Small bean-shaped glands located in the small vessels of the lymphatic system. There are thousands of lymph nodes located throughout the body, with clusters of them in the neck, under the arms, the ...
T-cell screening T-cells are made in the bone marrow, like all red and white blood cells. The name T-cell comes from the organ where they mature, the thymus. The thymus is just above your heart, and is about the size of a deck of playing cards. Since most T-cells are made when you’re young, kids have a bigger thymus than adults.
Treating T-Cell Non-Hodgkin Lymphoma. Non-Hodgkin lymphoma (NHL) is generally divided into main 2 types, based on whether it starts in B lymphocytes (B cells) or T lymphocytes (T cells). There are many different types of T-cell lymphomas, and treatment can vary based on which type you have.
A type of white blood cell. T-lymphocytes are part of the immune system and develop from stem cells in the bone marrow. They help protect the body from infection and may help fight cancer. Also called T cell and thymocyte. PubMed Health Glossary (Source: NIH - National Cancer Institute)
