B Lymphocytes. B lymphocytes constitute 5% to 20% of the peripheral blood mononuclear cells. B lymphocyte development occurs in two phases, an antigen-independent phase in the primary lymphoid tissues, followed by an antigen-dependent phase in secondary lymphoid tissues.

The lymphatic system is the group of tissues and organs, like the spleen, tonsils, and lymph nodes, that protect your body from infection (1). About 25 percent of the new lymphocytes remain in the Lymphocytes include natural killer cells (which function in cell-mediated, cytotoxic innate immunity), T cells (for cell-mediated, cytotoxic adaptive immunity), and B cells (for humoral, antibody -driven adaptive immunity). They are the main type of cell found in lymph, which prompted the name "lymphocyte". The discovery that lymphocyte subpopulations participate in distinct components of the immune response focused attention onto the origins and function of lymphocytes more than 40 years ago. Studies in the 1960s and 1970s demonstrated that B and T lymphocytes were responsible primarily for the basic … B-cell or B-lymphocyte is a type of white blood cell that stimulates your body's antibody factories, the plasma B-cells, and protect against infections.

B lymphocytes

B-lymfocyter. Svensk definition.

Morphologically B- cells are indistinguishable from T-cells. B-cells are identified by their surface protein ie. B lymphocytes or B cells produce antibodies involved in humoral immunity. B cells are produced in the bone marrow, where the initial stages of maturation occur, and travel to the spleen for final steps of maturation into naïve mature B cells.

2021-01-27 · The B lymphocyte (B cell) is one of the most important cells of the body. These cells form part of the adaptive immune response by producing antibodies and presenting antigens to T cells. Once activated, they can mature into plasma cells or memory B lymphocytes. This article covers B cell development and subtypes.

The B cells produce antibodies that are used to attack invading bacteria, viruses, and toxins. The T cells destroy the body's own cells that have themselves been taken over by viruses or become cancerous.

Immune system - Immune system - Activation of T and B lymphocytes: In its lifetime a lymphocyte may or may not come into contact with the antigen it is capable of recognizing, but if it does it can be activated to multiply into a large number of identical cells, called a clone. Each member of the clone carries the same antigen receptor and hence has the same antigen specificity as the original
