antigen specific immunity attributable to the production of antibody and of specific immune T lymphocytes (responsible for cell-mediated immunity), following exposure to an antigen, or passive transfer of antibody or immune lymphoid cells (adoptive immunity). active immunity.
Activation of the B-Cell receptor by antigen also results in the production of memory cells that persist in circulation to produce a more rapid immune response after future challenges by the same antigen. The bound antigen molecules are engulfed into the B-Cell by receptor-mediated endocytosis.-Cells are not only produced in the bone marrow but they also mature there. Each B-Cell is specific for a particular antigen. The specificity of binding resides in the BCR (B-Cell receptor) for antigen.
