Longitudinal plasma proteomic signatures of elite and viremic spontaneous HIV controllers.

ABSTRACT: A small percentage of people living with HIV (PLHIV) spontaneously regulate viral replication without suppressive antiretroviral treatment (ART) and are categorized into 'elite controllers' (EC, HIV-RNA < 50 c/mL) and 'viremic controllers' (VC, HIV-RNA between 50-10,000 c/ml). Some EC and VC may lose controller status in time. Here we provide extensive plasma proteomics to identify biomarkers and pathways related to spontaneous viral control and its long-term preservation among 36 EC and 147 VC (discovery) and 14 EC and 5 VC (validation). VC exhibited higher concentrations of CRTAM, LY9, and CD6 and lower concentrations of VAT1 compared to EC in both the discovery and validation cohort. Longitudinal analysis of pre- and post-ART samples (median follow-up: 5.3 years) revealed downregulation
