Viruses, Vol. 11, Pages 853: Functional Domains of the Herpes Simplex Virus Type 1 Tegument Protein pUL37: The Amino Terminus is Dispensable for Virus Replication in Tissue Culture Viruses doi: 10.3390/v11090853 Authors: Grzesik Pryce Bhalala Vij Ahmed Etienne Perez McCaffery Desai The herpes simplex virus type 1 (HSV-1) UL37 gene encodes for a multifunctional component of the virion tegument, which is necessary for secondary envelopment in the cytoplasm of infected cells, for motility of the viral particle, and for the first steps in the initiation of virus infection. This 120 kDa protein has several known viral interacting partners, including pUL36, gK/pUL20, pUS10, and VP26, and cellular interacting proteins which include TRAF6, RIG-I, and dystonin. These interactions are likely important for the functions of pUL37 at both early and late stages of infection. We employed a genetic approach to determine essential domains and amino acid residues of pUL37 and their associated functions in cellular localization and virion morphogenesis. Using marker-rescue/marker-transfer methods, we generated a library of GFP-tagged pUL37 mutations in the HSV-1 strain KOS genome. Through viral growth and ultra-structural analysis, we discovered that the C-terminus is essential for replication. The N-terminal 480 amino acids are dispensable for replication in cell culture, although serve some non-essential function as viral titers are reduced in the presence of ...

The word “hypermetabolism” needs to be replaced by “hypometabolism” at only ONE place and NOT throughout the article.So the correction could be stated as:“In the case description section, the sentence “A repeat dedicatedbrain FDG-PET scan performed on day 9, under burst suppression,showed diffuse hypermetabolism with persistent relativehypermetabolism in the left ventral striatum and septalarea (Fig. 1b).”should read as“A repeat dedicatedbrain FDG-PET scan performed on day 9, under burst suppression,showed diffuse hypometabolism with persistent relativehypermetabolism in the ...

AbstractA 71-year-old man presented with sudden onset, generalized tonic-clonic seizures and altered mental status. Initial brain magnetic resonance imaging was normal but a brain FDG-PET scan showed hypermetabolism in the left ventral striatum and septal area. Initial cerebrospinal fluid (CSF) examination showed mildly elevated protein but herpes simplex virus (HSV) polymerase chain reaction (PCR) was negative. A repeat CSF examination performed 9  days later showed a positive HSV PCR. Histopathological and immunohistochemical examination of autopsy specimen confirmed the presence of CD45+ lymphocytes and HSV antigen...

Conclusion Herpes encephalitis may rule your body but don't allow the infection to take over your brain. Herpes encephalitis is suppressible and so its symptoms if managed with great attention. Antiviral drugs such as Zovirax, acyclovir, Valacyclovir are some of the prominently used drugs in suppressing therapy of herpes infection. You are counseled to see your GP as soon as the very onset of any symptoms described above.You've read Cracking the Herpes Encephalitis Code | Causes, Symptoms and Treatment, originally posted on Pick the Brain | Motivation and Self Improvement.

Abstract Background and objectives: The purpose of this study was to describe corneal sensitivity and the morphological changes of sub-basal corneal nerves using in vivo laser scanning confocal microscopy (LSCM) in herpes simplex virus (HSV) keratitis-affected eyes, and to compare with both contralateral eyes and with the eyes of patients with a previous history of herpes labialis but no history of herpetic eye disease, and with healthy patients with no history of any HSV diseases, during the acute phase of the disease and after six months. Materials and Methods: A prospective clinical study included 269 patients....

Conclusions Several model systems are now available to characterize the MSC-tumour interplay in the TME. These offer early promise in establishing robust preclinical platforms for the identification of crucial molecular pathways and for the assessment of clinical efficacy of novel drugs to inhibit cancer development and progression. However, selection of the right model for a given study should be shaped on the purpose, and should also consider fixed biological, biochemical, and biophysical parameters according to the specific tumour type. Finally, in order to get reliable and useful results to be translated to the clinic...

In this study, we showed that KSHV-infected cells induce interferon-stimulated genes (ISGs) response but not type I interferon in uninfected bystander cells using EVs. mRNA microarray analysis showed that ISGs and IRF-activating genes were prominently activated in EVs from KSHV-infected cells (KSHV EVs)-treated human endothelial cells, which were validated by RT-qPCR and western blot analysis. We also found that this response was not associated with cell death or apoptosis by virus infection. Mechanistically, the cGAS-STING pathway was linked with these KSHV EVs-mediated ISGs expressions, and mitochondrial DNA on the surfa...

We report the case of a patient with a lengthy psychiatric history who presented with lower extremity pain and weakness. Cervical, thoracic, and lumbar MRI scans with and without gadolinium contrast revealed no significant stenosis, neural compression, or other abnormal findings, and the brain MRI with and without gadolinium contrast was normal. The initia l diagnosis was conversion disorder due to myriad psychological stressors. Polymerase chain reaction (PCR) of CSF detected HSV-2 and a lymphocytic pleocytosis, and the diagnosis of radiculomyelitis was confirmed. She was treated with i.v. acyclovir for 3 weeks followed b...
