One of three specialized lymphocyte types. B lymphocytes transform into plasma cells and produce antibodies in response to foreign substances such as bacteria, viruses, and fungi. B lymphocytes are a vital part of the immune system and are important to our defense against infection. B cells received their name from a structure called the bursa of Fabricius in birds, which was found to be the source of antibody-producing lymphocytes. In humans, the bone marrow may be the equivalent of the bursa. Thus, in humans “B†can be thought of as indicating that the lymphocytes are derived initially from the bone marrow.
a lymphocyte derived from bone marrow that provides humoral immunity; it recognizes free antigen molecules in solution and matures into plasma cells that secrete immunoglobulin (antibodies) that inactivate the antigens
cell that has been programmed to participate in the humoral immune response; when stimulated by antigen it proliferates and differentiates into antibody-producing cells and memory cells
The only cell type capable of producing antibody molecules and therefore the central cellular components of humoral immune responses. B lymphocytes or B cells, develop in the bone marrow and mature B cells are found mainly in lymphoid follicles in secondary lymphoid tissues, in bone marrow, and in low numbers in the circulation (1). In the brain, B lymphocytes may be seen in the perivascular space during inflammatory reactions and occasionally in normal CNS tissues (1).
One of the two major classes of lymphocytes, B lymphocytes are blood cells of the immune system derived from bone marrow and spleen. During infections, these cells are transformed into plasma cells that produce large quantities of antibody directed at specific pathogens. When antibodies bind to foreign proteins, such as those that occur naturally on the surfaces of bacteria, they mark the foreign cells for elimination by other cells of the immune system. This process occurs through interactions with various types of T-cells and other components of the immune system.
A white blood cell that makes antibodies and is an important part of the immune system. B lymphocytes come from bone marrow. Also called B cell.
A lymphocyte, also called a B cell, that matures without passing through the thymus. It matures into plasma cells that produce antibodies.
a lymphocyte derived from the bone marrow that makes antibody
B lymphocytes are white blood cells of the immune system that are derived from the bone marrow and spleen. B cells develop into plasma cells, which produce antibodies.
Lymphocyte that produces circulating antibodies or immunoglobulins.
A white blood cell that comes from bone marrow. As part of the immune system, B lymphocytes make antibodies and help fight infections. Also called B cell.
Type of lymphocyte which synthesizes and secretes antibodies in response to the presence of a foreign substance or one identified by it as foreign. The protective effect can be mediated to a certain extent by the antibody alone (contrast T lymphocyte) RT immune response, lymphocyte, T lymphocyte
The precursors of antibody-forming plasma cells; these cells carry immunoglobulin and class II MHC (major histocompatibility complex) antigens on their surfaces.
white blood cell that produces antibodies
B lymphocytes, or B cells, are white blood cells which make antibodies. Antibodies are protein molecules that are made in response to a foreign invader, such as a virus or bacteria. The antibody binds to the foreign substance and either destroys it or makes it easier for other cells in the immune system to destroy it.
