Immune System and HIV

HIV attacks and kills crucial immune system cells, known as T-helper cells. Without T-helper cells many other immune system cells cannot work properly, including B-cells that make antibodies. HIV is difficult for the body to deal with. This is because the cells that the body uses to fight a viral infection are instead used by HIV to reproduce and replicate. HIV then continues infecting other CD4 cells. These details of the immune response are very complicated. The main point is HIV makes the immune system become overactive, producing more and more cells. Over time the immune system loses out. This is why without HIV treatment your CD4 count drops over time.
