: Neurological conditions associated with HIV remain major contributors to morbidity and mortality and are increasingly recognized in the aging population on long-standing combination antiretroviral therapy (cART). Importantly, growing evidence shows that the CNS may serve as a reservoir for viral replication, which has major implications for HIV eradication strategies. Though there has been major progress in the last decade in our understanding of the pathogenesis, burden, and impact of neurological conditions associated with HIV infection, significant scientific gaps remain...

OBJECTIVES: HIV/1 group P (HIV-1/P) is the last HIV/1 group discovered and to date, comprises only two strains. To obtain new insights into this divergent group, we screened for new infections by developing specific tools, and analysed phenotypic and genotypic properties of the prototypic strain RBF168. In addition, the follow-up of the unique patient monitored so far, has raised the knowledge of the natural history of this infection and its therapeutic management. DESIGN/METHODS: We developed an HIV-1/P specific sero-molecular strategy and screened over 29,498 specimen samples...

OBJECTIVE: HIV-1 infection of the brain and related cognitive impairment remain prevalent in HIV-1-infected subjects despite combination antiretroviral therapy. Sterile alpha motif and histidine-aspartate domain-containing protein 1 (SAMHD1) is a newly identified host restriction factor that blocks the replication of HIV-1 and other retroviruses in myeloid cells. Cell-cycle-regulated phosphorylation at residue Thr592 and viral protein X (Vpx)-mediated degradation of SAMHD1 have been shown to bypass SAMHD1 restriction in vitro...

OBJECTIVE: Despite effective antiretroviral therapy (HAART) and durable viral suppression, many HIV-infected individuals still do not achieve CD4+ cell count (CD4) normalization. Vitamin D has immunoregulatory functions, including inducing the development of T cells, and higher levels may improve CD4 rebound. DESIGN: Longitudinal study of men from the Multicenter AIDS Cohort Study who virally suppressed following HAART initiation and had pre- and post-HAART 25[OH]D and 1,25[OH]2D measurements and repeated measures of CD4...

OBJECTIVES: Altered platelet function has been proposed as an underlying mechanism to explain increased risk of myocardial infarction in people living with HIV associated with use of the nucleoside reverse transcriptase inhibitor abacavir (ABC). We aimed to examine changes in platelet biomarkers in people living with HIV switching from ABC. METHODS: In a prospective, 48-week substudy of virally suppressed HIV-1-positive subjects randomized to remain on ABC/lamivudine (ABC/3TC) or switch to tenofovir disoproxil fumarate/emtricitabine, we measured soluble glycoprotein VI (sGPVI), soluble P-selectin, soluble CD40 ligand and von Willebrand factor in plasma collected over time and assessed differences using mixed effect models...
