Project description:We found that the germline transcription factor double homeobox 4 (DUX4) is upregulated upon infection with wild-type herpes simplex virus-1 (HSV-1). The goal of this experiment was to compare the cellular transcriptome of HEK293T cells that were infected with HSV-1 (KOS strain), or transfected with a plasmid encoding human DUX4.

Project description:Tissue resident memory T cells (TRM) provide superior protection against infection localised to extra-lymphoid compartments in the body. Here we show that CD103+CD8+ TRM cells develop in skin from killer cell lectin-like receptor (KLR)G1-negative precursors that selectively infiltrate the epithelial layer. In the skin, a combination of chemokine-guided epithelial entry, local interleukin (IL)-15 and transforming growth factor (TGF)-β signalling is required for formation and survival of these long-lived memory cells. Importantly, TRM differentiation results in the gradual acquisition of a unique transcriptional profile that differs from that expressed by memory cells in the circulation and other types of skin-resident intra-epithelial T cells, such as the dendritic epidermal T cells (DETC). We provide a comprehensive molecular and developmental framework for the local differentiation of a distinct type of peripheral memory T cell that contributes to an important first-line of immune defence in barrier tissues such as skin and mucosa. 24 samples were analyzed: 3 replicates of memory gB-T CD8+. CD103+ T cells isolated from the skin of C57/BL6 mice on day 30 p.i. with HSV KOS. 3 replicates of memory P14 CD8+ T cells isolated from gut of mice on day 60 p.i. with LCMV Armstrong. 3 replicates of memory gB-T CD8+ T cells from the lung of mice on day 30 p.i. with influenza WSN. 3 replicates of memory CD62L high CD8+ T cells from the spleen of mice on day 30 p.i. with HSV KOS. 3 replicates of memory CD62L low CD8+ T cells from the spleen of mice of day 30 p.i. with HSV KOS. 3 replicates of γδ-DETC isolated from the skin of C57/BL6 mice on day 30 p.i. with HSV KOS. 3 replicates of αβ-DETC from naive TCRδ-/- mice; and 3 replicates of naive gB-T CD8+ T cells from the spleen of naive gB-T transgenic mice.

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:Protein palmitoylation regulates diverse aspects of cellular function and organization and plays a key role in host immune responses to infection. Palmitoylation also modulates the function and localization of virus-encoded proteins. In Serwa et al. (doi:10.1016/j.chembiol.2015.06.024), we employed chemical proteomics tools, bio-orthogonal palmitic acid analogue (heptadec-16-ynoic acid, YnPal), and a multi-functional capture reagent (AzTB) to study palmitoylation events during infection with three strains of herpes simplex virus (HSV-1[17], HSV-1[KOS], HSV-2[186]). We found that a significant fraction of the viral proteome (twelve HSV-encoded proteins) undergoes palmitoylation; we identified a number of virus membrane glycoproteins, structural proteins, and kinases. Furthermore, we identified palmitoylation sites on five HSV-encoded proteins utilising a complementary methodology (Acyl-RAC). This paper also reports selective HSV-induced alterations to palmitoylation and myristoylation of host proteins.

Project description:In this study, we investigated the effects of HSV-1 infection on tau phosphorylation in human brain cortical organoids. Our findings demonstrate that HSV-1 triggers nuclear accumulation of phosphorylated tau in neurons within the developing cortical plate as well as in neural precursor cells (NPCs) in the ventricular/subventricular-like zones of these differentiating cortical structures. Antiviral treatment effectively inhibited nuclear tau accumulation in both KOS- and 17syn+-infected organoids. Importantly, for the first time we provide evidence of a potential interaction of phosphorylated tau with HSV-1 genome. Furthermore, we ruled out the involvement of the Cyclin-dependent kinase 5 (Cdk5) in the nuclear phosphorylation of tau. Finally, we show that HSV-1 causes a significant alteration in the abundance of components of nuclear speckles and proteins known to be associated with neurodegenerative diseases.
