White blood cells known as CD4+ T cells are the main target of HIV. The virus hijacks these cells and replicates within them, which ultimately destroys the cell. This depletion of the T cell population represents a major blow to the immune system and puts HIV-infected individuals at increased risk of opportunistic infections. Treatment of HIV-infected individuals with a cocktail of drugs called combination antiretroviral therapy (c-ART) is able to restore the T cell population and help fight HIV infection, however not all patients respond to this therapy. The growth factor interleukin-7 (IL-7) is known to stimulate T cell production and survival, suggesting that IL-7 may help restore the T cell population during HIV infection...
