Project description:Diagnosis of TB, especially in the presence of an HIV co-infection, can be challenging when using conventional diagnostic methods. In this study, we analyzed global gene expression data from PBMC of patients that were either mono-infected with HIV or co-infected with HIV and TB in order to identify a TB-specific gene signature. Total RNA obtained from PBMC from a South African cohort. Microarry analysis was performed to compare gene expression in patients either infected with HIV or co-infected with HIV/TB.

Project description:Genome wide DNA methylation profiling of PBMC from South African patients either infected with HIV only or coinfected with HIV and tuberculosis (TB). The Illumina Infinium 27k Human DNA methylation Beadchip was used to obtain DNA methylation profiles from PBMC samples. Samples included 19 HIV patients and 20 HIV/TB co-infected patients. Bisulphite converted DNA were hybridised to the Illumina Infinium 27k Human Methylation Beadchip v1.2

Project description:Hepatic complications of HCV infection, including fibrosis and cirrhosis are accelerated in HIV-infected individuals. Although liver biopsy remains the gold standard for staging HCV-associated liver disease, this test can result in serious complications and is subject to sampling error. These challenges have prompted a search for non-invasive methods for liver fibrosis staging. To this end, we compared serum proteome profiles at different stages of fibrosis in HIV/HCV co- and HCV mono-infected patients using SELDI-TOF MS.

Project description:HIV-1 and HIV-2 are two etiological agents of Acquired Immune Deficiency Syndrome (AIDS). Several differences exist between these two retroviruses in terms of geographical distribution, replication, transmission and progression to AIDS. The molecular reasons explaining these features are largely unknown. One reason could rely on host factors able to differently counteract HIV replication. Among these factors, cellular microRNAs (miRNAs) have recently emerged as playing crucial roles. One aspect of the complex interplay between HIV and host miRNAs is the ability of HIV-1 to modulate host miRNAs and thereby to create favorable conditions for its replication. Here, we sought to compare the miRNA modulations elicited by HIV-1 and HIV-2 using an unbiased experimental strategy based on miRNA arrays. Surprisingly, we observed that these two unrelated HIVs similarly modulated the host miRNA repertoire, when utilizing CD4 and CXCR4 for entry. However, these modulations were different from the changes triggered by HIV-1 using CD4 and CCR5. In accordance with the mode of action of miRNAs, our observations were confirmed at the mRNA level. We concluded that co-receptor utilization (CXCR4 or CCR5), as opposed to genomic organization and phylogeny, is a key event determining the modulations of the host miRNA repertoire.

Project description:HIV uses dendritic cells as a carrier to infect its target CD4+ T cells. At the same time, it also hampers DCs function in terms of their T cell stimulatory capacity and cytokine secretion. We have shown that HIV causes reduction in the expression of co-stimulatory molecules, CD80 and CD86 by DCs at the mRNA level irrespective of the viral subtype or the mode in DC-HIV interaction. The microarray experiments were performed to understand the changes in the transcription factor profile of HIV infected DCs which may in turn lead to reduced CD80/CD86 expression as well as the effect of HIV infection on other co-stimulatory molecules on DCs. The data suggests that TFs NFKB1, NFKB2, REL and MYB may be responsible for the observed decrease in CD80 and CD86 expression and that HIV infection also hampers the expression of other co-stimulatory molecules like CD70, CD30, 4-1BB, OX40L etc. The total RNA was isolated from LPS matured DCs (positive control) and HIV infected DCs using Qiagen RNeasy Minikit. Agilent Quick-Amp Labelling kit (p/n 5190-0444) was used to synthesize the labeled cDNA from 3 ug of total RNA and further process the hybridized cDNA on the array. All the steps were carried out according to manufacturerM-bM-^@M-^Ys instructions (www.agilent.com/chem/dnamauals-protocol). The array slides were scanned immediately using high throughput Agilent scanner with SureScan technology. Agilent feature extraction software was used for normalization and statistical analysis,. Pathway and gene ontology analysis was done using Genespring GX v 10.0 and biointerpreter software. The experiments were performed on DCs cultured from two independent donors. The differential expression was considered if the Log 2 mean of at least -1 for the down regulated genes and +1 for the upregulated genes. We considered only the genes that were differentially regulated genes in both the donors.
