How do T-cells respond to an HIV infection?

The T cells increase their amount and start fighting HIV. Then, when HIV destroys the T cells they use them to reproduce.

HIV targets and infects CD+4 T-cells. CD+4 T-cells respond by replicating 80-90% of their original levels and attack the virus. Ultimately, HIV overwhelms the germinal centers that produce CD+4 T-cells.

Those cells are immunity cells and help fight infection. They measure the amount of those cells to determine how well the immunity system is working. To little or to many can indicate an infection.
