Term
1. Exogenous Agn is picked up by tissue macrophage
2. Macrophage binds to Agn and exposes epitope
3. Epitope is transferred to T4 cell
4. T4 cell with epitope attached to TCR is now activated (Activated T4 cell)
5. Activated T4 cell can now become a Th1 or Th2 cell
6. Th1 cell produces and secretes chemicals called cytokines or Lymphokines
7. Th2 cell transfers epitope to surface of a B-lymphocyte.
8. B-lymphocyte becomes a plasma cell, which makes antibodies. |

1. Endogenous antigen is picked up by APC.
2. APC binds to Agn and exposes epitope.
3. Epitope is transferred to T8 Cell and is activated.
4. Activated T8 cell can now become one of the following cells: Th1 cell, Th2 cell, CTL, T-memory cell or a
T-suppressor cell. |
