Project description:Dengue virus is an + strand RNA virus. We have carried our infections of human cells with Dengue and analyzed the translation, replication, and localization of the Dengue RNA. This allowed for clear definition of the life cycle of the Dengue virus inside a host cell. We also assessed the host response to Dengue virus, finding that a large fraction of the translational response is due to Interferon function. Translational and transcriptional analysis of the cellular response to Dengue virus infection

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:Dengue virus infection can result in severe symptoms including shock and hemorrhage, but an understanding of the molecular correlates of disease severity is lacking. Bulk transcriptomics on blood samples are difficult to interpret because the blood is composed of different cell types that may react differently to virus infection. Dengue virus RNA can be detected in human plasma, however identifying the cells carrying dengue virus through the bloodstream in vivo has proven challenging. Here we used our recently developed viscRNA-Seq approach to profile transcriptomes of thousands of single blood peripheral mononuclear cells from 6 human subjects with dengue fever and severe dengue, as well as to characterize the cell types associated with dengue virus in the human blood. We found that although no bulk transcriptome marker for severe dengue exists, the expression of MX2 in naive B cells, of CD163 in CD14+/CD16+ monocytes and of other genes in specific cell types is highly predictive for severe dengue. We detected virus-associated cells in the blood of two severe dengue patients with high viral load and discovered the majority of these to be B cells expressing germline IgM or IgD immunoglobulin chains and naive markers but also showing signs of activation and expression of CD69, CXCR4, and other surface receptors. In bystander B cells we detected signs of strong immune activation, parallel hypersomatic evolution and, in one severe degue subject, an anomalously large clone of highly mutated, IgG1 plasmablasts that could be reactive to dengue virus. This study presents a high-resolution molecular exploration into dengue virus infection in humans and can be generalized to any RNA virus.

Project description:Dengue virus is the most common arbovirus worldwide and represents a significant public health concern. To date, chronic Dengue infections have not been previously reported. While investigating the etiology of central nervous system (CNS) disease in a patient presenting with progressive dementia, we elucidated a chronic dengue infection within the CNS. Comprehensive viral immune responses in both serum and cerebrospinal fluid (CSF) were profiled by a phage-display assay (VirScan). Enrichment of Dengue viral antibodies were detected in the CSF as compared to the serum. No virus was detected in serum or CSF, but post-mortem analysis confirmed Dengue virus in the brain by quantitative polymerase chain reaction (PCR), immunohistochemistry, RNAscope and sequencing. Dengue virus was detectable by PCR and sequencing from brain biopsy tissue collected 33 months ante-mortem, confirming a chronic infection. Comprehensive antibody profiling assays can aid in the diagnosis of encephalitis of unknown etiologies. Our findings suggest that Dengue virus infections may persist in the CNS and should be considered in patients with progressive dementia in endemic regions or with relevant travel history.

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:This study aimed to use pan-viral detection microarrays to identify viruses in serum from cases of acute pediatric febrile illness in a tropical setting. Patient clinical data and serum samples were collected between 2005 and 2009 as part of an ongoing pediatric dengue virus study at the Hospital Infantil Manuel de Jesús Rivera in Managua, Nicaragua. This study focused on patients who presented with dengue-like illness but who tested negative for dengue-virus infection. We hypothesized that non-dengue viruses or previously uncharacterized viruses might be causing these illnesses. The Virochip microarray is capable of detecting known viruses and discovering novel viruses. This series includes 153 arrays corresponding to 148 cases and 5 HeLa controls.
