Lymphocyte of the Thymus Gland

Lymphocytes of the thymus (or thymus) gland are cells of the immune system that are located in this organ, on the surface of which thymic proteins (lymphopeptides) are produced. Their main function is control over antigen-reactive cells, for which they have type II receptors for immunoglobulins on their membrane, which bind and destroy any extraneous, foreign cells that enter the body. They also have receptors that allow them to identify their own (tissue and antigen-presenting cells). Another important function of these cells is to maintain favorable, anti-inflammatory protection of this organ, which affects the functioning of other cells of the body. They suppress the development of T lymphocytes if they begin to produce excessive amounts of protein. Lymphocytes also protect us from cancer of this gland.

**Lymphocytes** - a type of leukocytes responsible for the reactions of the immune system (from the Latin “lymphos” - arising from lymphoid tissue, “semen” - seed, i.e. lymphocytes formed from lymphoid tissues); There are several varieties of these cells. The main task of these cells is to provide cellular immunity.

**Thymic lymphocytes** are white blood cells that make up about a quarter of all human blood. The precursor of this cell population developed from a hematopoietic stem cell: this is how B lymphocytes are formed - the precursors of blood plasma cells. Leukemic B cells are called tumor cells because they are capable of proliferation (rapid division), and then perform the function of producing antibodies - proteins that can react to the antigen. Under normal conditions, the function of plasma (B-lymphocyte) cells is impaired.
