Wikipedia

  1. B cell

    B cells, also known as B lymphocytes, are a type of white blood cell of the lymphocyte subtype. They function in the humoral immunity component of the adaptive immune system. B cells produce antibody molecules which may be either secreted or inserted into the plasma membrane where they serve as a part of B-cell receptors. When a naïve or memory B cell is activated by an antigen, it proliferates and differentiates into an antibody-secreting effector cell, known as a plasmablast or plasma cell. Additionally, B cells present antigens (they are also classified as professional antigen-presenting cells (APCs)) and secrete cytokines. In mammals, B cells mature in the bone marrow, which is at the core of most bones. In birds, B cells mature in the bursa of Fabricius, a lymphoid organ where they were first discovered by Chang and Glick, which is why the 'B' stands for bursa and not bone marrow as commonly believed. B cells, unlike the other two classes of lymphocytes, T cells and natural killer cells, express B cell receptors (BCRs) on their cell membrane. BCRs allow the B cell to bind to a foreign antigen, against which it will initiate an antibody response. B cell receptors are extremely specific, with all BCRs on a B cell recognizing the same epitope.

  1. b cell

    A B cell is a type of white blood cell and an important component in the immune system. They are a vital part of the adaptive immune system, responsible for producing antibodies which are used to attack invading bacteria, viruses, and toxins. B cells also have the ability to remember harmful substances, enabling the immune system to respond quickly when encountering the same threat again.

  1. B cell

    B cells belong to a group of white blood cells known as lymphocytes, making them a vital part of the immune system -- specifically the humoral immunity branch of the adaptive immune system. B cells can be distinguished from other lymphocytes, such as T cells and natural killer cells, by the presence of a protein on the B cell's outer surface known as a B cell receptor. This specialized receptor protein allows a B cell to bind to a specific antigen. The principal functions of B cells are to make antibodies against antigens, to perform the role of antigen-presenting cells, and to develop into memory B cells after activation by antigen interaction. Recently, a new, suppressive function of B cells has been discovered. The abbreviation "B", in B cell, comes from the bursa of Fabricius in birds, where they mature. In mammals, immature B cells are formed in the bone marrow, which is used as a backronym for the cells' name, despite the fallacious etymology.
