Project description:Herpes simplex virus type 2 (HSV-2) is a common human pathogen that establishes lifelong latency in neurons of the nervous system. The number of severe central nervous system infections caused by the virus has increased recently. However, the pathogenesis of HSV-2 infection in the nervous system is not fully understood. Here, we demonstrated global proteomic changes in the brain tissue in BALB/c mice vaginally infected with HSV-2.

Project description:The overall goal of the study was to use in vivo data combined with functional genomics to define gene expression signatures representative of a spectrum of HSV CNS infections. Innate immune deficiencies result in a spectrum of severe clinical outcomes following infection. In particular, there is a strong association between loss of the signal transducer and activator of transcription (Stat) pathway, breach of the blood-brain barrier (BBB), and virus-induced neuropathology. The gene signatures that characterize resistance, disease, and mortality in the virus-infected nervous system have not been defined. Herpes simplex virus type 1 (HSV-1) is commonly associated with encephalitis in humans, and humans and mice lacking Stat1 display increased susceptibility to HSV central nervous system (CNS) infections. In this study, two HSV-1 strains were used, KOS (wild type [WT]), and Δvhs, an avirulent recombinant lacking the virion host shutoff (vhs) function. In addition, two mouse strains were used: strain 129 (control) and a Stat1-deficient (Stat1(-/-)) strain. Using combinations of these virus and mouse strains, we established a model of infection resulting in three different outcomes: viral clearance without neurological disease (Δvhs infection of control mice), neurological disease followed by viral clearance (Δvhs infection of Stat1(-/-) mice and WT infection of control mice), or neurological disease followed by death (WT infection of Stat1(-/-) mice). Through the use of functional genomics on the infected brain stem and liver, we determined gene signatures that were representative of the three infection outcomes. Gender matched, 6- to 8- week old immunocompetent, control 129S6 and 129S6 Stat1 knockout mice were infected corneally with 2x10^6 PFU of either wild type HSV-1, a vhs-null HSV virus, or mock-infected. Brain stems and liver of individual mice were isolated at days 1, 3, 5 and 7 post-inoculation for microarray analysis. For microarray analysis, samples were collected from n=2 animals (1 male, 1 female) per mouse strain and virus strain for each time point. Equal masses of tissue were pooled from two mock-infected mice per time point and run on microarray.

Project description:Dendritic cells (DCs) regulate both innate and adaptive immune responses. The role of CD11c-plus DCs in the corneal response to to herpes simplex virus-1 (HSV-1) infection was investigated by depleting them prior to infection.

Project description:Dendritic cells (DCs) regulate both innate and adaptive immune responses. The role of CD11c-plus DCs in the corneal response to to herpes simplex virus-1 (HSV-1) infection was investigated by depleting them prior to infection. Bone marrow cells from CD11c-DTR (C.FVB-Tg(Itgax-DTR/EGFP)57Lan/J) mice were transferred intravenously to irradiated BALB/cJ host mice. After 6 weeks, the bone marrow chimeric host mice were injected with diphtheria toxin (DT) to deplete CD11c-positive cells. Two days after injection, the mice were subjected to a standard corneal infection protocol using HSV-1.

Project description:The purpose of this study was to determine which genes are differentially regulated virus infection in RAW264.7 cells. Cells were infected with Vesicular Stomatitis Virus (VSV) or herpes simplex virus 1 (HSV-1) for 6h. Then the differentially regulated genes were analyzed, focusing on F-box proteins and E3 ubiquitin ligases. RAW264.7 cells were infected with Vesicular Stomatitis Virus (VSV, MOI=1) or herpes simplex virus 1 (HSV-1, MOI=5) for 6h. Equal amounts of RNA were assayed for gene expression using Affymetrix mouse 430 2.0 arrays.

Project description:To identify functional lncRNAs in microglia-neurotropic virus interaction, high-throughput RNA sequencing was performed to obtain differential expressed lncRNAs (DELs) in microglia isolated from C57BL/6J mice, infected with or without neurotropic virus herpes simplex virus type 1 (HSV-1) (MOI 1 per group). All samples contain three mice’s microglia as a mixture given the isolated amount is low.

Project description:We have previously developed the use of genetically engineered herpes simplex virus type 1 ("G207") for the experimental treatment of malignant glioma (PMID: 18957964). We demonstrated that G207 propagates in and kills nervous system tumor cells with little to no evidence of viral encephalitis. Here, six adult patients with recurrent glioblastoma were recruited onto a phase Ib clinical trial to test G207 safety and efficacy in anti-tumor response. We obtained resected tumor tissue before and after (within 2-5 days) inoculation with G207. RNA was extracted from all tissues and subject to library preparation for RNA sequencing on Illumina instrumentation.
