Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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).

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Cohort A, group A1

Quantify, by droplet digital PCR, the expression of a panel of 7 genes (+ GALIG) involved in autophagy2 on sub-populations (CD4+ and CD8+ lymphocytes and monocytes) after their sorting using magnetic bead cell then RNA extraction Evaluate, on a functional test (as previously described1), whether the observed expression dysregulation is associated with a deregulation of the autophagic function, whether constitutive or induced.
