Project description:Tuberculous meningitis is one of the fatal forms of extra pulmonary disease associated with high mortality and severe neurological defects in affected individuals. We have carried out transcriptome level analysis using whole human genome microarrays to identify differential expression of genes between tuberculous meningitis and normals. In our gene expression analysis, we found 2,434 genes that were differentially erexpressed with 2 or more than 2 fold changes between tuberculous meningitis compared to normal cases. Most of the genes encoded many of the proteins, which involves metabolism, energy pathways, cell growth and/or maintenance, transport and cell communication and signal transduction. We have performed immunohistochemistry for the validation of some of the novel candidates identified in our microarray studies.!Series_overall_design = Present study carried out mRNA expression profiling of five samples from patients diagnosed with tuberculous meningitis and four head injury cases were used as controls. We have used 4X44K arrays from agilent plaform. To validate our microarray results, we have done Immunohistochemistry on 15 TBM cases with control groups.

Project description:Tuberculosis co-infected with HIV may increase the risk of causing meningitis. Tuberculous meningitis co-infected with HIV associated with high mortality and severe neurological abnormalities in affected individuals. We have carried out TBM co-infected with HIV gene expression study using whole human genome microarrays. We identified 796 differentially expressed genes with fold change cut off of 2 or more than 2. Out of 796 differentially expressed genes, 398 were upregulated and 396 were downregulated. We have validated two molecules from microarray data using immunohistochemistry. The proposed study carried out mRNA expression profiling of five samples from patients diagnosed with tuberculous meningitis coinfected with HIV and four head injury cases were used as controls. We have used 4X44K arrays from agilent platform. To validate our microarray results, we have done immunohistochemistry on 10 TBM+HIV cases and 10 control groups.

Project description:In order to identify the potential biomarkers for discriminating tuberculous meningitis (TBM) and viral meningitis (VM) and to reveal the different pathophysiological processes between TBM and VM, a genome-wide miRNA screenings of peripheral blood mononuclear cells (PBMCs) from TBM, VM, and healthy controls (HCs) using microarray assay was performed (12 samples). Twenty-eight differentially expressed miRNAs were identified between TBM and VM, and 11 differentially expressed miRNAs were identified between TBM and HCs. The 6 overlapping miRNAs detected in both TBM vs. VM and TBM vs. HCs were verified by qPCR analysis and showed a 100% consistent result with that in microarray test.

Project description:Patients with HIV-associated TB meningitis (TBM) are known to experience systemic hyperinflammation, clinically known as immune reconstitution inflammatory syndrome (IRIS), following the commencement of antiretroviral therapy (ART). No prognostic markers or biomarkers have been identified to date and little is known about the mechanism mediating the hyperinflammation. We recruited a prospective cohort of 33 patients with HIV-associated TBM, 16 of whom developed TBM-IRIS, and performed transcriptomic profiling. Transcriptomic signatures that distinguish patients who would eventually develop IRIS were identified and indicated neutrophil and inflammasome activation as being the predominant mediator of TBM-IRIS pathogenesis.
