- B cell (the antibody factory): Keep memory B cells for later
- Helper T cell (the commander): Immunity remembered for next time
- Bloodstream (the highway): Raise a fever to slow the virus
- Helper T cell (the commander): Call for more B and killer T cells
- Killer T cell (the assassin): Hunt infected cells
- Lymph node (the war room): Test the next T cell type
