Schizophrenia bulletin 20140312 1

<h4>Background</h4>Herpes simplex virus, type 1 (HSV-1) commonly produces lytic mucosal lesions. It invariably initiates latent infection in sensory ganglia enabling persistent, lifelong infection. Acute HSV-1 encephalitis is rare and definitive evidence of latent infection in the brain is lacking. However, exposure untraceable to encephalitis has been repeatedly associated with impaired working memory and executive functions, particularly among schizophrenia patients.<h4>Methods</h4>Patterns of ...[more]

Human cellular models for Herpes Simplex Virus, type 1 (HSV-1) using induced pluripotent stem cell derived neuronal lineages

Project description:Herpes simplex virus type 1 (HSV-1) is a 152 Kb double stranded DNA alpha-herpesvirus, which establishes long life latent infection in sensory neurons. Most of our knowledge regarding HSV-1 latency comes from in vivo studies using small animal models, mainly rodents and rabbits, which are not naturally infected by HSV-1. Furthermore, these animal models do not fully recapitulate the species specific effects of human HSV-1 infection. Human cellular models utilize trigeminal ganglia removed from cadavers or, alternatively, neuron-like cells derived from cancerous cell lines that do not fully reflect effects on normal human neurons. This limitation poses the need to develop an in vitro model to investigate molecular details of the mechanisms underlying latency and reactivation in human neurons. Induced pluripotent stem (iPS) cell technologies offer an unprecedented opportunity to generate unlimited supplies of neurons and the facility to manipulate such cells in vitro. In this study, we developed an in vitro HSV-1 infection model in human iPS-derived neural progenitor cells (NPCs) and neurons, which displays the main hallmarks of latency defined in animal models and in humans. Induced pluripotent stem (iPS) cells were generated from human skin biopsy samples

In this study, we developed an in vitro HSV-1 infection model in human iPS-derived neurons, which displays the main hallmarks of latency defined in animal models and in humans. Our results show for the first time that: i) persistent infection cannot be established in neural progenitor cells (NPCs); ii) the ability of HSV-1 to establish persistent infection is extended to glutamatergic neurons, and not limited to sensory neurons; iii) in neuronal cultures persistently infected with HSV-1, viral genome is localized at the nuclear periphery; iv) HSV-1 acute infection reduces RNA editing at the GluRB site. These results highlight the importance of iPS-based platforms to elucidate unknown aspects of HSV-1 quiescence in human neurons. NPCs were 70-80% confluence

Mutant Huntingtin impairs neurodevelopment in human brain organoids through CHCHD2-mediated neurometabolic failure

Project description:Expansion of the poly-glutamine (Q) tract in the protein Huntingtin (HTT) causes the neurodegenerative disorder Huntington’s disease (HD). Emerging evidence suggests that mutant HTT (mHTT) disrupts brain development. To gain mechanistic insights into the neurodevelopmental impact of human mHTT, we engineered induced pluripotent stem cells to introduce a 70Q expansion or remove the poly-Q tract. mHTT introduction caused aberrant development of cerebral organoids with loss of neural progenitor organization. The early neurodevelopmental signature of mHTT highlighted the dysregulation of coiled-coil-helix-coiled-coil-helix domain containing 2 (CHCHD2), which is involved in mitochondrial integrated stress response. CHCHD2 repression was associated with abnormal mitochondrial morpho-dynamics and elevated resting energy expenditure. Elimination of the poly-Q tract reverted CHCHD2 expression and mitochondrial defects. Hence, mHTT-mediated disruption of human neurodevelopment is paralleled by aberrant neurometabolic programming mediated by dysregulation of CHCHD2, which could then represent a target of early intervention for HD.

Expression data from RAW264.7 murine macrophages infected with Toxoplasma gondii and subsequently stimulated with interferon-gamma

Project description:Toxoplasma strains are known to inhibit the expression of several interferon-gamma induced genes, and a type II strain was shown to dysregulate genome-wide responses to interferon-gamma in human fibroblasts (Kim et al., 2007, J Immunol.). In this study we aimed to determine the effect of infection with three clonal lineages of Toxoplasma, type I, II, and III strains on genome-wide interferon-gamma induced transcription in murine macrophages. We also assessed the effect of the two main Toxoplasma modulators of mouse macrophage transcription, ROP16 and GRA15 (Jensen et al., 2011, Cell Host Microbe). We used Affymetrix microarrays to analyze host cell transcription after Toxoplasma infection and interferon-gamma stimulation. RAW264.7 murine macrophages were left uninfected or infected with type I (RH), type I ?rop16 (RH ?rop16), type II (Pru), type II ?gra15 (Pru ?gra15), or type II (CEP) parasites at an MOI ~5 for 18 hours and subsequently stimulated with murine IFN-? for six hours. Plaque assays were done to assess parasite viability. Total RNA was isolated and hybridized to Affymetrix Mouse 430A 2.0 gene chips.

Analysis of global gene expression profiles of hPAF1 deficient A549 cells during stimulation with PR8/∆NS1 influenza virus, IFNβ1 or Poly(I:C)

Project description:Viral infection is commonly associated with virus-driven hijacking of host proteins. We describe a novel mechanism by which influenza virus impacts host cells through the interaction of influenza NS1 protein with the infected cell epigenome. We show that the NS1 protein of influenza A H3N2 targets the transcription elongation PAF1 complex (hPAF1C). We demonstrate that binding of NS1 to hPAF1C results in suppression of hPAF1C-mediated transcriptional elongation. More importantly,in the following data sets, we show that hPAF1 plays a crucial role in the antiviral response. Loss of hPAF1C reduces antiviral gene expression and reduces inducible transcription of target genes after stimulation with viral RNA analogue poly(I:C), vesicular stomatitis virus (VSV), exogenous recombinant IFN(beta) and influenza virus (H1N1). This study underscores the importance of hPAF1C in controlling inducible antiviral gene expression. Untreated (no siRNA), control siRNA-treated and hPAF1 siRNA-treated A549 cells were stimulated with PR8/∆NS1 influenza virus (MOI 1), IFNβ1 (500U/mL) or Poly(I:C) (2ug/mL). Total RNA was isolated with the Qiagen RNeasy mini kit. 200ng of total RNA per sample was used to prepare biotin-labeled RNA using MessageAmp™ Premier RNA Amplification Kit (Applied Biosystems) and hybridized to HumanHT-12 v4 Expression BeadChips (Illumina). Data analysis was performed using the GeneSpring GX11.0 software (Agilent Technologies). 3 biological replicates per condition

Proteomic analysis of Human Adenovirus B and C infections in the presence of interferon

Project description:Human adenoviruses (HAdV) are a large family of DNA viruses generally infecting the airway, the gut, the eye, and the urinary tract. However, certain strains of HAdVs are capable of causing severe infections in the very young, the elderly, the immunocompromised, and sometimes healthy individuals. In particular, species B HAdVs are often associated with more severe disease, involving serotype 7 and 14. Despite the severity of the disease caused by these strains, little is known about the molecular mechanisms underpinning the disease outcomes. Activation of interferon stimulated genes (ISGs) occurs rapidly after interferon (IFN) stimulation and relies on recruitment of the transcription factor complex IFN-stimulated gene factor 3 (ISGF3) to promoters, which happens via the canonical JAK-STAT pathway. Therefore, suppression of IFNs is a key aspect of evading innate immunity by viral pathogens, including HAdVs; and as such, HAdVs have evolved multiple ways by which they suppress activation of ISGs in order to drive viral replication. Our previous work investigated the molecular mechanism of interferon suppression by HAdV-C5. We observed that E1A of HAdV-C5 interacts with the AAA+ DNA helicase RuvBL1/Pontin in order to suppress activation of interferon stimulated genes (ISGs) during infection. We therefore wanted to determine whether RuvBL1 is also a target for the more highly pathogenic HAdV-B7 and B14. As part of this investigation, we examined the broad-range effect of HAdV species C2, B7, and B14 on cells in response to interferon. These results are presented here.

Wide-spread disruption of transcription termination in HSV-1 infection: Next generation sequencing of total and newly transcribed (4sU-RNA) RNA

Project description:Primary human foreskin fibroblasts (HFF) were infected with wild-type simplex virus 1 (HSV-1) strain 17 at a multiplicity of infection (MOI) of 10. Newly transcribed RNA was labelled by adding 500µM 4-thiouridine (4sU) to the cell culture media for 1h. Total cellular RNA was isolated using Trizol. Newly transcribed RNA was purified following the protocol described in Raedle et al. JoVE 2013. Newly transcribed RNA was labelled in one hour intervals during the first eight hours of HSV-1 infection. All nine 4sU-RNA samples as well as total cellular RNA of every second hour of infection were sent for sequencing. Two independent biological replicates were analysed.
