Transcription profiling of human HIV seropositive patients, CD4+ T cell decline is predicted by differential expression

ABSTRACT: Patterns of expressed genes examined in cryopreserved peripheral blood mononuclear cells (PBMCs) of seropositive persons electing to stop antiretroviral therapy in the AIDS Clinical Trials Group Study A 5170, were scrutinized to identify markers capable of predicting the likelihood of CD4+ T cell depletion after cessation of ART. Two cohorts were matched for clinical characteristics in a study of the effects of therapy interruption (TI) in ART-treated patients with immunological preservation. Disease progression was determined by CD4+ T cell count decline 24 weeks after TI.Gene Set Enrichment Analysis (GSEA) identified a set of genes in the Ras signaling pathway, associated with the downregulation of apoptosis, as significantly upregulated in the good outcome group at cessation of ART. Experiment Overall Design: There are 96 samples in this study. 24 patients with good outcome results and 24 matched patients with poor outcome results. Each patient has two time points: week0 and week 24

Melatonin alters the transcriptome of human granulosa cells and improves fertilization and blastocyst formation

Project description:Granulosa cells in the ART cycle before and during melatonin treatment from the three patients and analyzed the transcriptome changes by RNA-sequence. The other four patients had good ART outcomes. Their GCs were also subjected to RNA-sequence as controls of good ART outcomes.

Transcription profiling of human peripheral blood mononuclear cells infected with HIV-1

Project description:We used Affymetix HG Focus GeneChip to measure the expression levels of HIV seronegative and seropositive individuals in human PBMCs in vivo. GSM39104 -GSM39115 are HIV seronegative samples; GSM39116-GSM39137 are HIV seropositive but drug naive samples; GSM39138-GSM39147 are HIV seropositive samples used to test serostatus biomarker; GSM39148-GSM39170 are HIV seropositive individuals whose CD4 cells decrease over time; GSM39171-GSM39187 are HIV seropositive individuals whose CD4 cells increase over time; GSM39188-GSM39190 are HIV seropositive samples used to test CD4 cell increase/decrease over time.

Paradoxical CD4 decline on ART: a novel, rare and perplexing immunologic outcome

Project description:The goal of antiretroviral therapy (ART) is to suppress HIV-1-replication and reconstitute CD4-T-cells. Here, we report on HIV-infected individuals, who had a paradoxical decline in CD4-T-cells despite ART-mediated suppression of plasma HIV-1 load (plHIV-1). We defined such immunological outcome as extreme immune decline (EXID).

Transcriptional analysis of HIV-specific CD4+ T cells after suppression of viremia by ART.

Project description:The virus-specific CD4+ T cell dysfunction associated with failure to control chronic infections is poorly understood in humans. An issue of critical clinical relevance is the lack of restoration of effective anti-HIV immunity after suppressive ART: viral rebound is the rule after cessation of therapy. Whether persistent HIV-specific CD4+ T cell dysfunction on ART contribute to this failed response is an important, yet unresolved, question. To decipher the consequences of ongoing viral antigen exposure, versus the results of durable cell-fate decision programs that would persist in former CP individuals after successful viral suppression on ART, we compared trancriptional profiles of chronic progressor before and after the initiation of ART, with the transcriptional profiles of elite controllers, HIV-infected individuals that spontaneously control viral load. Suppression of viremia by ART resulted in a distinct transcriptional landscape, with reduction in TFH gene expression but no correction of the TH1, TH17 and TH22 gene levels compared to the elite controller profile.

In vivo and in vitro proteome analysis of HIV-1 infected, human CD4+ T cells

Project description:Host directed therapies against HIV-1 are thought to be critical for long term containment of the HIV-1 pandemic but remain elusive. Since HIV-1 infects and manipulates important effectors of both the innate and adaptive immune system, identifying modulations of the host cell systems in humans during HIV-1 infection may be crucial for the development of immune based therapies. Here, we quantified the changes of the proteome in human CD4+ T cells upon HIV-1 infection, both in vitro and in vivo. A SWATH-MS approach was used to measure the proteome of human primary CD4+ T cells infected with HIV-1 in vitro as well as CD4+ T cells from HIV-1 infected patients with paired samples on and off antiretroviral treatment. In the in vitro experiment, the proteome of CD4+ T cells was quantified over a time course following HIV-1 infection. 1,725 host cell proteins and 4 HIV-1 proteins were quantified, with 145 proteins changing significantly during the time course. Changes in the proteome peaked 24 hours after infection, concomitantly with significant HIV-1 protein production. In the in vivo branch of the study, CD4+ T cells from viremic patients and those with no detectable viral load after treatment were sorted and the proteomes quantified. We consistently detected 895 proteins, 172 of which were considered to be significantly different between viraemic patients and patients undergoing successful treatment. The proteome of in vitro infected CD4+ T cells was modulated on multiple functional levels, including TLR-4 signalling and the type 1 interferon signalling pathway. Perturbations in the type 1 interferon signalling pathway were recapitulated in CD4+ T cells from patients. The study shows that proteome maps generated by SWATH-MS indicate a range of functionally significant changes in the proteome of HIV infected human CD4+ T cells. Exploring these perturbations in more detail may help identify new targets for immune based interventions.

Innate and antigen-specific cytotoxic cells and Paradoxical HIV-associated Tuberculosis Immune reconstitution inflammatory syndrome (TB-IRIS)

Project description:Tuberculosis Immune Reconstitution Inflammatory Syndrome (TB-IRIS) frequently complicates combined anti-retroviral therapy (ART) and anti-tubercular therapy in HIV-1 co-infected tuberculosis (TB) patients. The immunopathological mechanism underlying TB-IRIS is incompletely defined. Differential transcript abundance in PBMC from IRIS and control patients stimulated with heat killed H37Rv was determined by microarray Blood samples were collected during longitudinal observational studies of TB-IRIS patients and controls (both groups HIV-infected patients placed on antiretroviral treatment). PBMC were stimulated with heat killed H37Rv and RNA extracted.
