CD4+ Cells - Topic Overview

CD4+ cells are part of the immune system and are a type of white blood cell. White blood cells protect the body against infection. CD4+ cells are also called T-lymphocytes, T-cells, or T-helper cells.

HIV invades and destroys CD4+ cells. But the body continues to produce new CD4+ cells to fight the HIV infection. If the infection is not treated with medicines, the body gradually loses the ability to produce enough CD4+ cells to replace the number that are being destroyed by HIV. As the number of CD4+ cells in the blood drops, it becomes harder for the immune system to fight infections.
