Sequential Analysis Before and After Treatment Initiation to Unravel the Role of Naturally Occurring Extracellular Vesicles in HIV Infection

This study aims to evaluate the role of extracellular vesicles in HIV-infection, by determining the expression profile and content of EVs before and after treatment initiation in HIV-infected patients, through extensive blood and tissue sampling (leukapheresis, stool sampling and colon biopsies). A one-time sampling (blood, stool, colon biopsies) will also be performed in HIV-seronegative healthy volunteers to confirm that results found in HIV-infected patients are related to the disease.
