Specialised cells of the immune system which help to fight infections by making antibodies. They are also called B-lymphocytes. In Type 1 diabetes, they help the T cells to kill the beta cells by making antibodies targeted specifically at the beta cells – these are called autoantibodies.
Antibody-producing white blood cells, which mature in the bone marrow. The letter B originally came from bursa of Fabricius where B lymphocytes originate in chickens, but has subsequently been extended to imply the bone marrow.
Type of lymphocyte responsible for antibody-mediated immunity; mature in the bone marrow and circulate in the circulatory and lymph systems where they transform into antibody-producing plasma cells when exposed to antigens.
Small white blood cells crucial to the immune defenses. Also known as B lymphocytes (Read about " The Lymph System"), they are derived from bone marrow and develop into plasma cells that are the source of antibodies.
One of the immune system's cell types; B cells fight infection primarily by making antibodies. During the time of infection, these cells are transformed into factories that make thousands of antibodies against the foreign antigen.
White blood cells that have not travelled to the thymus (see T cells). B cells are responsible for many immune functions, such as producing proteins called antibodies that tag invaders for destruction. B cells respond to the presence of antigens by dividing and maturing into plasma cells.
Lymphocytes which develop in the bone marrow in adults and produce antibody. They can be subdivided into two groups, B1 and B2. B1 cells use minimally mutated receptors which are close to the germline immunoglobulin sequences, whereas B2 cells are the major responding population in conventional immune responses to protein antigens.
