Study of Autophagy and the Effects of GALIG Gene Products in HIV-1 Infected Patients Who Are Under Antiretroviral Therapy Since Primary-infection, Chronic Phase, or Never Treated.

Little is known about autophagy during HIV infection. Recently, two different teams reported important dysfunctions of autophagy in HIV-infected patients despite sustained suppressive antiretroviral therapy. As altered autophagy is strongly linked to cellular senescence and chronic inflammation, two hallmarks of HIV-infected patients despite long-term suppressive antiretroviral therapy, it is important to improve our knowledge in the area. Our main objective is to determine whether all or part of mononuclear cell subpopulations (CD4+ and CD8+ T lymphocytes, and monocytes) exhibit a defect in autophagy function in a cohort of HIV-infected patients who are virologically-controlled (plasma HIV RNA \<50 copies / ml) either spontaneously (i.e. HIV controllers or post-treatment controllers) or after they started antiretroviral therapy at different time points (i.e. at the acute or chronic phases), as compared with a control group (i.e. uninfected healthy blood donors).

Fasting Mimicking Diet and Autophagy

This study aims to evaluates autophagy in circulating white blood cells from generally healthy human volunteers exposed to fasting mimicking diet (FMD), a 5-day dietary regimen.
