The immune response is mounted against specific agents and a memory of the agent is retained in order to mount a vigorous defense if the invader reappears later in life.

B cells from bone marrow make antibodies which are used to recognize foreign material in the body. One antibody is specifically designed to attack one antigen. Cytotoxic T cells secrete a potent toxin that kills cells targeted by the immune system.looo Tc cytotoxic cells. Capable of killing cells infected with virus, bacterial pathogens and some tumor cells. Shut down the response at the appropriate time.
