Summary Introduction
Introduction:
The humoral responses are the immune response to the foreign antigen that occurs by the production of specific antibodies produced by the plasma cells. It takes place with the help of the B cells and the T helper cells.
Cell-Mediated immunity does not involve the activity of the antibodies. T takes place by the activation of the phagocytic cells. The components involved in this are cytotoxic t lymphocytes, cytokines, etc.
