Type of lymphocyte derived from bone marrow stem cells that matures into an immunologically competent cell under the influence of the bone marrow. Following interaction with an antigen, a B-cell becomes a plasma cell, which synthesizes antibodies.
an immune system white blood cell that carries out the humoral (TH2) immune response. B-cells are produced in the bone marrow and mature into plasma cells that produce antibodies. B-cells are influenced by various cytokines and interactions with T-cells and other immune system components. Contrast with T-cell.
A type of lymphocyte (see) that is a precursor to plasma cells. During infections, individual B-cell clones multiply and are transformed into plasma cells, which produce large amounts of antibodies against a particular antigen (see) on a foreign microbe. This transformation occurs through interaction with the appropriate CD4 T-helper cells.
lymphocyte that circulates in the body identifying foreign organisms (i.e., viruses, parasites, bacteria, fungi) to be destroyed; transforms into plasma cells and produces specific antibodies once a foreign microorganism is identified. For more information please click here.
A type of white blood cell and, specifically, a type of lymphocyte. Many B cells mature into what are called plasma cells that produce antibodies (proteins) necessary to fight off infections while other B-cells mature into memory B-cells.
