1. Postencephalitic chronic granulomatous disease.
Match Strength: 11.355
This report details the evolution of a case of herpes simplex encephalitis to chronic granuloma in a 13-year old female who, at the age of 8, suffered herpes simplex virus type 1 encephalitis. Eight months later, she developed an intracranial hypertension syndrome with the onset of a new lesion in the necrosed zone of her right temporal lobe, with no viral presence in the cerebrospinal fluid. The histologic characteristics were those of chronic granuloma with multinucleated giant cells and calcifications. Initially treated for neurosarcoidosis, the patient remained steroid-dependent for 4 ... Read More »

2. Common and specific properties of herpesvirus UL34/UL31 protein family members revealed by protein complementation assay.
Match Strength: 8.970
The proteins encoded by the UL34 and UL31 genes of herpes simplex virus are conserved among herpesviruses. They form a complex that is essential for the egress of the herpesvirus nucleocapsids from the nucleus. In previous work on the homologous protein complex in murine cytomegalovirus (MCMV), we defined their mutual binding domains. Here, we started to map binding domains within the UL34/UL31 proteins of alpha-, beta-, and gammaherpesviruses and to locate other functional properties. A protein complementation assay (PCA) using the TEM-1 beta-lactamase fragments fused to UL31 and UL34 protein ... Read More »

3. Reconstitution of herpes simplex virus type 1 nuclear capsid egress in vitro.
Match Strength: 8.536
Newly assembled herpesvirus capsids travel from the nucleus to the plasma membrane by a mechanism that is poorly understood. Furthermore, the contribution of cellular proteins to this egress has yet to be clarified. To address these issues, an in vitro nuclear egress assay that reproduces the exit of herpes simplex virus type 1 (HSV-1) capsids from nuclei isolated from infected cells was established. As expected, the assay has all the hallmarks of intracellular transport assays, namely, a dependence on time, energy, and temperature. Surprisingly, it is also dependent on cytosol and was ...

4. Tissue-specific splicing of the herpes simplex virus type 1 latency-associated transcript (LAT) intron in LAT transgenic mice.
Match Strength: 7.971
To study the regulation of herpes simplex virus type 1 (HSV-1) latency-associated transcript (LAT) expression and processing in the absence of other cis and trans viral functions, a transgenic mouse containing the region encompassing the LAT promoter (LAP1) and the LAT 5' exon through the 2.0-kb intron was created. LAT expression was detectable by reverse transcriptase PCR (RT-PCR) in a number of tissues, including the dorsal root ganglia (DRG), trigeminal ganglia (TG), brain, skin, liver, and kidney. However, when the accumulation of the 2.0-kb LAT intron was analyzed at the cellular level by ... Read More »

5. ICP22 is required for wild-type composition and infectivity of herpes simplex virus type 1 virions.
Match Strength: 7.302
The immediate-early regulatory protein ICP22 is required for efficient replication of herpes simplex virus type 1 in some cell types (permissive) but not in others (restrictive). In mice infected via the ocular route, the pathogenesis of an ICP22- virus, 22/n199, was altered relative to that of wild-type virus. Specifically, tear film titers of 22/n199-infected mice were significantly reduced at 3 h postinfection relative to those of mice infected with wild-type virus. Further, 22/n199 virus titers were below the level of detection in trigeminal ganglia (TG) during the first 9 days ... Read More »

6. Childhood encephalitis in Crete, Greece.
Match Strength: 6.451
This study included all 18 cases of children hospitalized for encephalitis in the referral university hospital of Heraklion, Crete, Greece, during the 5-year period from 2000 to 2004. Encephalitis was attributed to viral infection (echovirus, herpes simplex virus 1, varicella-zoster virus, cytomegalovirus, and influenza A) in eight children and to bacteria (Mycoplasma pneumoniae, group A beta-hemolytic streptococcus, and Rickettsia typhi) in a further five cases. Multiple hyperintense brain lesions on magnetic resonance imaging (MRI) were associated with a severe clinical presentation but not ... Read More »

7. Sequence and function of canine herpesvirus alpha-transinducing factor and its interaction with an immediate early promoter.
Match Strength: 5.707
The sequence of the alpha-transinducing factor (alpha-TIF) of canine herpesvirus (CHV-l) was determined. Alignment of the predicted CHV-1 alpha-TIF amino acid sequence with other alpha-TIF homologues reveals a core region of similarity with divergent amino and carboxyl termini. Analysis of the CHV-1 infected cell protein 4 promoter region identified a region containing nine copies of a 52 bp repeat that showed significant up-regulation of transcription by alpha-TIF. This region contained an imperfect 'TAATGARAT' motif, the binding site for herpes simplex virus 1 alpha-TIF, with an imperfect ... Read More »

8. Identification of a 709-amino-acid internal nonessential region within the essential conserved tegument protein (p)UL36 of pseudorabies virus.
Match Strength: 5.701
Tegument proteins homologous to the essential herpes simplex virus type 1 UL36 gene product (p)UL36 are conserved throughout the Herpesviridae and constitute the largest herpesvirus-encoded proteins. So far, only limited information is available on their functions, which include complex formation with the (p)UL37 homologs via an N-terminal domain and a deubiquitinating activity in the extreme N terminus. For further analysis we constructed deletion mutants lacking 437, 784, 926, 1,046, 1,217, or 1,557 amino acids (aa) from the C terminus. While none of them supported replication of a ... Read More »

9. Gene therapy of liver tumors with human liver-specific nanoparticles.
Match Strength: 5.270
The development of safe and efficient liver-specific gene delivery approaches offers new perspectives for the treatment of liver disease, in particular, liver cancer. We evaluated the therapeutic potential of hepatotropic nanoparticles for gene therapy of liver tumor. These nanoparticles do not contain a viral genome and display the hepatitis B virus L antigen, which is essential to confer hepatic specificity. It has not been shown whether a therapeutic effect could be obtained using L nanoparticles in a human liver tumor xenograft model. Rats bearing human hepatic (NuE) and non-hepatic tumors ...

10. Effect of oral valaciclovir on herpetic keratitis.
Match Strength: 4.999
PURPOSE:: To examine the efficacy of valaciclovir (VACV) oral formulation as an alternative to topical treatments in a case of herpetic keratitis. METHODS:: The patient was a 61-year-old man who presented with dendritic keratitis in his left eye. After recognizing his difficulty in using eye ointment, we prescribed oral VACV 500 mg tablets twice daily for 7 days. We also describe our experiments with orally administered VACV in a mouse model of this disease. In this study, 143 Balb/c mice were inoculated with herpes simplex virus type 1 (HSV)-1 in each eye and treated with oral VACV 50 or 100 ... Read More »

11. Rapid detection, serotyping and quantitation of dengue viruses by TaqMan real-time one-step RT-PCR.
Match Strength: 4.984
The use of the polymerase chain reaction (PCR) in molecular diagnosis is now accepted worldwide and has become an essential tool in the research laboratory. In the laboratory, a rapid detection, serotyping and quantitation, one-step real-time RT-PCR assay was developed for dengue virus using TaqMan probes. In this assay, a set of forward and reverse primers were designed targeting the serotype conserved region at the NS5 gene, at the same time flanking a variable region for all four serotypes which were used to design the serotype-specific TaqMan probes. This multiplex one-step RT-PCR assay ... Read More »

12. Gene transfer into Purkinje cells using herpesviral amplicon vectors in cerebellar cultures.
Match Strength: 4.933
Purkinje cells play a crucial role in sensory motor coordination since they are the only output projection neurons in the cerebellar cortex and are affected in most spinocerebellar ataxias. They stand out in the central nervous system due to their large size and their profusely branched dendritic arbor. However, molecular and cellular studies on Purkinje cells are often hampered by the difficulty of maintaining these cells in culture. Here we report an easy, robust and reproducible method to obtain Purkinje-enriched mixed cerebellar cell cultures from day 16 mouse embryos using papain ... Read More »
