CELL MEDIATED RESPONSE

• PROCESS OF THE CELL MEDIATED RESPONSE?

  1. Pathogen is engulfed and destroyed by phagocyte
  2. Antigens presented in cell surface (becomes APC)
  3. T helper cells attach to antigens on APC by receptors
  4. Activates T helper cells to divide by mitosis to replicate
  5. Creates a large number of clones
  6. Cloned T helper cells differentiate into different cells
• WHAT HAPPENS TO THE CLONED T HELPER CELLS AFTER DIFFERENTIATION?

  • some stay as T helper cells and activate B lymphocytes
  • some stimulate macrophages to perform phagocytosis
  • some become memory cells
  • some become T cytotoxic cells (killer T cells)
