    Cards (2)

    • describe the events which lead up to a T cell producing genetically identical clones in response to an infection
      -pathogens invade the body
      -antigen presenting cells present antigen on cell surface membrane
      -receptors on specific T-helper cell bind to complementary antigen
      -helper T cells undergo mitosis to form clones
    • What happens to cloned T-cells during an infection
      -develop into memory cells for rapid response in future infections
      -stimulate phagocytes to start phagocytosis
      -stimulate B cells to undergo mitosis and produce antibodies
      -activate cytotoxic T cells which kill infected cells
