en.wikipedia.org/wiki/T_cell

A T cell is a type of lymphocyte which develops 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, derived from bone marrow, and develop into several distinct types of T cells once they have migrated in to 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. Immature T cells (termed T-stem cells) migrate to the thymus gland in the neck, where they mature and differentiate ...

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-cells protect our bodies against disease by eliminating cancerous cells, and those infected with viruses and bacteria. However, because T-cells have evolved not to attack our own tissue in order to limit autoimmune disease, T-cell responses to cancer, which develops from our own tissue, are poor. In order to resolve this problem, we have developed strategies to build T-cells with an ...

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.

Differences Between B-Cells and T-Cells. T cells and B cells are the major cellular components of the adaptive immune response. T cells are involved in cell-mediated immunity, whereas B cells are primarily responsible for humoral immunity.

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.

T cell listen (... sel) A type of white blood cell. T cells 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 lymphocyte and thymocyte.

The surface of each T cell also displays thousands of identical T cell receptors (TCRs). There are two types of T cells that differ in their TCR: alpha/beta (αβ) T cells. Their TCR is a heterodimer of an alpha chain with a beta chain. Each chain has a variable (V) region and a constant (C) region.
