Cell- mediated response

- The cell mediated response involves T-cells that act directly against the foreign organism, working similary to an antibody but without binding to the antigens directly
- T-cells
- Rather then binding to the direct antigen they instead bind with the MHC marker molecules presented on the surface of the cell
-Types of t-cells:
- Helper t-cells
- Recognise foreign antigens
- Recognition helps stimulate B cells to enlarge into plasma cells and produce appropriate antibodies to kill the pathogen.
- Cytoxic (killer) T-cells
- This process stop the virus from reproducing inside the host cell
- Suppressor T-cells
- Signal other cells to cease their attack by releasing their own lymphokines
- Prevent the immune system from destroying healthy tissue
- Memory T-cells
- If the pathogen enters the body again the secondary response will be much quicker in destroying it.
