T cell - Wikipedia
T cells are one of the important types of white blood cells of the immune system and play a central role in the adaptive immune response. T cells can be distinguished from other lymphocytes by the presence of a T-cell receptor (TCR) on their cell surface. T cells are born from hematopoietic stem cells, [1] found in the bone marrow.

6 天之前 · T cell, 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 responses to antigens (foreign substances) in the body.
T cells populate virtually every organ and tissue, including primary and secondary lymphoid tissue, mucosal and barrier sites, exocrine organs, fat, and even the brain and central nervous system.

There are two main classes of T cells—cytotoxic T cells and helper T cells. Effector cytotoxic T cells directly kill cells that are infected with a virus or some other intracellular pathogen. Effector helper T cells, by contrast, help stimulate the responses of other cells—mainly macrophages, B cells, and cytotoxic T cells.

2024年10月21日 · T Cell Production and Maturation. T cells, like all other white blood cells involved in innate and adaptive immunity, are formed from multipotent hematopoietic stem cells (HSCs) in the bone marrow (see Figure 17.3.1).However, unlike the white blood cells of innate immunity, eventual T cells differentiate first into lymphoid stem cells that then become small, immature lymphocytes, sometimes ...
