Question

Quizplus · Accepted Answer

Memory B cells are responsible for the ability of an organism to produce a rapid antibody response against a foreign protein when it is encountered years after the first encounter. They are created during the initial encounter with an antigen and can rapidly produce large amounts of antibodies upon re-exposure to the same antigen. Memory T cells also play a role in the immune response, but they specifically target cells infected with a virus or other intracellular pathogen. Cytotoxic T cells target and lyse cells infected with a virus or other intracellular pathogen. Plasma cells produce and secrete antibodies in response to an antigen. Antigen-presenting cells play a role in presenting antigen to other cells of the immune system for recognition and response.
