Project description:Dengue viruses cause two severe diseases that alter vascular fluid barrier functions, dengue hemorrhagic fever (DHF) and dengue shock syndrome (DSS). While the mechanisms that lead to vascular permeability are unknown, the endothelium plays a central role in regulating fluid and cellular efflux from capillaries. Thus, dysregulation of endothelial cells functions by dengue virus infection may contribute to pathogenesis and severe disease. We used microarrays to investigate the effect of dengue virus infection on gene expression within primary human endothelial cells at various times post infection and identified numerous upregulated antiviral and immune response genes. Early passage primary endothelial cells (HUVECs) were mock infected (no virus) or infected with dengue virus and total RNA collected at 3 timepoints: 12, 24, and 48 hours post infection. Multiple timepoints were analyzed to identify changes in gene expression levels over time. Gene expression from both mock infected and dengue virus infected endothelial cells was evaluated to determine fold induction at each timepoint.

Project description:Analysis of ex vivo isolated lymphatic endothelial cells from the dermis of patients to define type 2 diabetes-induced changes. Results preveal aberrant dermal lymphangiogenesis and provide insight into its role in the pathogenesis of persistent skin inflammation in type 2 diabetes. The ex vivo dLEC transcriptome reveals a dramatic influence of the T2D environment on multiple molecular and cellular processes, mirroring the phenotypic changes seen in T2D affected skin. The positively and negatively correlated dLEC transcripts directly cohere to prolonged inflammatory periods and reduced infectious resistance of patients´ skin. Further, lymphatic vessels might be involved in tissue remodeling processes during T2D induced skin alterations associated with impaired wound healing and altered dermal architecture. Hence, dermal lymphatic vessels might be directly associated with T2D disease promotion. Global gene expression profile of normal dermal lymphatic endothelial cells (ndLECs) compared to dermal lymphatic endothelial cells derived from type 2 diabetic patients (dLECs).Quadruplicate biological samples were analyzed from human lymphatic endothelial cells (4 x diabetic; 4 x non-diabetic). subsets: 1 disease state set (dLECs), 1 control set (ndLECs)

Project description:Analysis of the host response to dengue virus at gene expression level. The hypothesis tested in the present study was that dengue virus triggers and regulate different pathaway with different kinetics controlling the antiviral, the inflammatory and the apoptotic response in primary human DC. Results provide important information of the response to DC to dengue virus showing that antioxidant genes are early stimulated after denv infection reflecting an early production of reactive oxygen species. Interestingely, we demonstrated that ROS production and antiviral and apoptotic responses intersect since chemical inhibition of ROS impairs antiviral and apoptotic responses in these cells. Total RNA obtained from in vitro dengue infected primary human dendritic cells at 0, 6, 12, 18, 24 hours compared to uninfected cells at time 0

Project description:Dengue virus can infect and cause systemic damage in many organs, resulting in organ failure. Here, we present a novel report showing a tailored stem cell-based therapy which can aid in viral clearance and rescue liver and blood vessels cells from further damage during dengue infection by administering combination of hematopoietic stem cells, endothelial progenitor cells and dental pulp stem cells in a dengue virus-infected BALB/c mouse model. To analyze the molecular level changes induced by DENV infection and stem cell treatment in dengue-infected mice, RNA sequencing (RNA-seq) using MiSeq next-generation sequencing was employed in this study. Transcriptomics analysis was performed comparing gene expression patterns in different experimental groups. Methods: Liver mRNA profiles of 21-day-old healthy, Dengue virus infected, and dengue infected plus stem cells treated BALB/C mice were generated by sequencing, in triplicate, using Illumina Miseq V3 150. The sequence reads that passed quality filters were assembled and analyzed using Tuxedo software. The results were analyzed using Cuffdiff to identify differentially expressed genes and transcripts. The relative expression of genes was determined based on FPKM (total fragments per kilobase of exon per million mapped reads) values Results: After analysis, it was found that 59 genes were significantly up-regulated in the DVI group, and in the DVI-SCT group, 47 of the genes were successfully corrected to the level similar to that of control group, while the remaining genes showed down-regulation Conclusion: In the recent years, the incidence of dengue has continued to increase, but there is currently no rapid and effective treatment available. This study demonstrates stem cell therapy as a promising management to reduce the global burden of dengue.
