Impact of Early Antiretroviral Therapy Initiation on HIV-Specific CD4 and CD8 T Cell Function in Perinatally Infected Children

Project description:14 children vertically HIV infected ART treated within 6 months of life (ET) and 6 children vertically HIV infected ART treated after 12 months of life were studied to understand the effect of early ART initiation on HIV specific CD4+ T cells and CD8+ T cells functionalities. Additionally, RNAseq on unstimulated PBMC was performed to also evaluate the impact of early ART on the immune transcriptome.

Monocyte involvement in HIV-Tuberculosis-associated Immune Reconstitution Inflammatory Syndrome at initiation of antiretroviral therapy

Project description:Tuberculosis-associated Immune Reconstitution Inflammatory Syndrome (TB-IRIS) is a common complication in HIV-TB co-infected patients receiving combined antiretroviral therapy (cART). While monocytes/macrophages play major roles in both HIV- and TB-infection individually, a putative contribution of monocytes to the development of TB-IRIS remains unexamined. We performed a genome-wide array analysis on MOs purified from peripheral blood mononuclear cells (PBMCs) obtained before initiation of combined antiretroviral therapy (cART) to verify whether the transcriptome of MOs was already significantly modulated (even before receiving cART) in HIV+/TB+ patients who later developed TB-IRIS compared to control HIV+/TB+ patients who did not develop the complication . The subjects under study included a subset of 18 TB-IRIS patients and controls matched for age, gender and CD4 count.

Effect of HIV infection and antiretroviral therapy initiation on genome-wide DNA methylation patterns.

Project description:Background. Previous epigenome-wide association studies have shown that HIV infection can disrupt the host DNA methylation landscape. However, it remains unclear how antiretroviral therapy (ART) affects the HIV-induced epigenetic modifications. Methods. 184 individuals with HIV from the NEAT001/ANRS143 clinical trial (with pre-ART and post-ART samples [96 weeks of follow-up]) and 44 age-and-sex matched individuals without HIV were included. We compared genome-wide DNA methylation profiles in whole blood between groups adjusting for age, sex, batch effects, and leucocyte type heterogeneity. Findings. We identified 430 differentially methylated positions (DMPs) between HIV+ pre-ART individuals and HIV-uninfected controls. In participants with HIV, ART initiation modified the DNA methylation levels at 845 CpG positions and restored 49.3% of the changes found between HIV+ pre-ART and HIV-uninfected individuals. We only found 15 DMPs when comparing DNA methylation profiles between HIV+ post-ART individuals and participants without HIV. The Gene Ontology enrichment analysis of DMPs associated with untreated HIV infection revealed an enrichment in biological processes regulating the immune system and antiviral responses. In participants with untreated HIV infection, DNA methylation levels at top HIV-related DMPs were associated with CD4/CD8 ratios and viral loads. Changes in DNA methylation levels after ART initiation were weakly correlated with changes in CD4+ cell counts and the CD4/CD8 ratio. Interpretation. Control of HIV viraemia after 96 weeks of ART initiation restores most of the host DNA methylation changes that occurred before antiretroviral treatment of HIV infection.

Gene expression profiles of peripheral blood mononuclear cells from HIV and HCV coinfected patients before and after 24 weeks of combined antiretroviral therapy.

Project description:We aim to characterize HIV and HCV coinfected patient response to combined antiretroviral therapy through genome-wide expression profiling of patients' periperhal blood mononuclear cells before and after treatment initiation (baseline and 24 weeks). Individuals with frank cirrhosis were excluded from the study. We used Affymetrix PrimeView arrays to quantify baseline transcriptomic characteristics and changes in the transcriptome following treatment. Gene expression changes were analyzed based on the change in expression of each transcript per patient. Mononuclear cells were purified from peripheral blood samples of 8 patients with HIV and HCV coinfection at baseline and after 24 weeks of combined antiretroviral therapy. Genes from whole blood RNA was measured via Affymetrix PrimeView microarrays.

The latent HIV reservoir in the brain of people with HIV under antiretroviral therapy (scRNA-Seq)

Project description:A growing body of data suggests that the human brain serves as a sanctuary for HIV persistence despite life-long antiretroviral therapy. Microglia, the innate immune cells of the brain parenchyma, may serve as a reservoir for rebound of HIV infection. The extent of the latent brain reservoir and molecular phenotype of HIV infected microglia cells, however, are unknown. To address this major knowledge gap, we leveraged the ‘Last Gift’ rapid autopsy cohort to perform a multi-omics approach (single cell RNA-seq, single cell ATAC-seq, and H3K27ac ChIP-seq) of the myeloid compartment creating a gene expression and chromatin accessibility atlas of human microglia isolated from three male individuals with HIV on suppressive antiretroviral therapy.

HIV Infection and Antiretroviral Therapy Have Divergent Effects on Mitochondria in Adipose Tissue

Project description:Exploratory microarray analysis identified significant changes in gene expression in adipose tissue. These included changes in genes regulating lipid and steroid metabolic processes and electron carrier activity in HIV-infected patients receiving antiretroviral therapy (ART). Additional genes involved in metabolic processes and mitochondrial function were found to be up-regulated in the adipose tissue of HIV-positive patients compared with HIV-negative controls. To identify differential gene expression in different tissues (PBMC, muscle, adipose tissue) between HIV patient groups (HIV negative, HIV positive with ART, HIV positive without ART).

B-cell compartment hyperactivation in PHIV

Project description:Despite a successful antiretroviral therapy (ART), adolescents living with perinatally acquired HIV (PHIV) experience signs of B-cell hyperactivation with expansion of 'namely' atypical B-cell phenotypes, including double negative (CD27-IgD-) and termed age associated (ABCs) B-cells(T-bet+CD11c+), which may result in reduced cell functionality, including loss of vaccine-induced immunological memory and higher risk of developing B-cells associated tumors. In this context,perinatally HIV infected children (PHIV) deserve particular attention, given their life-long exposure to chronic immune activation.
