- MATURE IN THE THYMUS GLAND
- PLURIPOTENT MARROW CELL
- T-HELPER CELL
- Communication link
- Recognise the non self antigen that the macrophage presents
- stimulate B-CELLS to produce plasma cells
- B-CELLS cannot do this without T-HELPER CELLS
- EFFECTOR CELLS

- stimulate B-CELLS to produce plasma cells
- Recognise the non self antigen that the macrophage presents
- Communication link
- CYTOTOXIC KILLERS
- Attach body cells which have been affected with viruses, bacteria and fungi
- Kill the cell by recognition of the VIRAL PROTEIN COAT
- Secrete PERFORIN PROTEIN which can perforate the cell membrane (LYSIS)

- EFFECTOR AND MEMORY CELLS
- Once activated they divide rapidly - POLYCONAL EXPANSION
- Once activated they divide rapidly - POLYCONAL EXPANSION
- T-SUPPRESSOR CELLS
- REGULATE the action of lymphocytes -
- Prevent the system from over reacting to stimuli

- REGULATE the action of lymphocytes -
- T-KILLER CELLS
- Activated in the thymus
- Sensitised when they encounter an antigen
- Further development goes on in lymphatic tissues
