Antibody‐Mediated (Humoral) Immunity (AMI)On exposure to antigenic determinants in lymphatic organs, B-lymphocytes are activated and differentiated to form plasma cells. Plasma cells are specialized, differentiated cells that synthesize and secrete antibodies specific for an antigen. Other activated B-lymphocytes form memory cells. These cells can be activated later to differentiate to plasma cells for rapid antibody production. This antibody production will occur on future reentry of the antigen to the body and is the basis of long-term immunity.The products of plasma cells are antibodies. An antibody is a specialized protein substance produced by the host cells in response to an antigen in the host's tissues. Antibodies are capable of reacting specifically with the antigen that provoked their production. Antibodies are often referred to as immunoglobulins.
