Abstract
Interleukin-7 (IL-7) is a cytokine that plays a critical role in T cell homeostasis by promoting proliferation and survival of mature T cells and also by enhancing thymic output for the generation of new T cells. IL-7 receptor expression and signaling function is perturbed in HIV infection and could contribute to disease pathogenesis. Even though highly active anti-retroviral therapy has markedly reduced morbidity and mortality in HIV-infected persons, there remains concern that a significant proportion of treated patients may experience relatively poor CD4+ T cell recovery despite sustained viral suppression. Recent human trials and animal studies suggest that IL-7 administration may provide a powerful tool to enhance T cell reconstitution in HIV-infected persons. The role of IL-7/IL-7 receptor perturbations in HIV pathogenesis and the potential to reconstitute immunity with IL-7 administration in the setting of HIV infection are important areas of investigation.

Management of HIV: Management of HIV: old challenges and new needs
The aim of this thematic issue is to provide the most recent updates regarding the effective management of HIV infection. Antiretroviral therapy (ART) has significantly decreased HIV-related mortality, leading to an enhancement in the quality of life and life expectancy for people living with HIV (PLWH). Despite the numerous advancements ...read more
