Early antiretroviral treatment may preserve key immune responses to HIV

Ragon Institute study findings could pave the way to vaccine development Instituting combination antiretroviral (ART) treatment at the earliest stages of HIV infection may allow the generation of functional CD8…

Study examines effects of alcohol, HIV, HCV on immune system activation

A study examined how biomarkers of microbial translocation and innate immune activation were affected by HIV status, HCV co-infection, and alcohol use. Alcohol use among people living with HIV (PLWH) may exacerbate…

Novel antibody may suppress HIV for up to four months
