Expression, Purification, and Crystallization of Full-Length HSV-1 gB for Structure Determination.

Expression, Purification, and Crystallization of Full-Length HSV-1 gB for Structure Determination. Methods Mol Biol. 2020;2060:395-407 Authors: Cooper RS, Heldwein EE Abstract HSV glycoproteins play important roles in the viral life cycle, particularly viral cell entry. Here we describe the protocol for expression, purification, and crystallization of full-length HSV-1 glycoprotein B. The protocol provides a framework for incorporating transmembrane domain-stabilizing amphipols into the crystallization setup and can be adapted to isolate other complete HSV glycoproteins.

CONCLUSIONSAcute VZV infection may present as fulminant hepatitis. The presentation may initially be challenging for the diagnosis and should be considered if the patient has been in contact with a sick case. Low dose corticosteroid could carry a risk for fatal VZV fulminant hepatitis and should be used very cautiously especially with VZV patients’ contacts. Further causative relationships remain to be established.

Conclusion: PCR evidence of infection with herpes group viruses was found in one-third of patients with hypertensive anterior uveitis; CMV being the most common pathogen. The PCR-positive group generally responded well to a combination of antiviral and anti-glaucoma treatment. PMID: 31697590 [PubMed - as supplied by publisher]

Conclusion: ICVM can assist in diagnosing endotheliitis. The results demonstrate that changes in the cornea were not different among the various viruses except for owl's eye morphology, the lengths of the subbasal nerves and Langerhans cell densities.

This study evaluated the performance of RealStar® alpha Herpesvirus PCR Kit 1.0 on the LightCycler® 480 Instrument II for detection and differentiation of HSV-1, HSV-2, and VZV in human clinical specimens. We evaluated the analytical sensitivity of the RealStar® and in-house multiplex real-time PCR assays using serial dilutions of nucleic acids extracted from clinical specimens. The analytical sensitivity of the RealStar® assay was 10, 32, and 100 copies/reaction for HSV-1, HSV-2, and VZV, respectively, which was slightly higher than that of the in-house multiplex real-time PCR assay. Reproducibility of the...

This study analyzes the tumor homing and therapeutic abilities of clinical grade human mesenchymal stem cells (MSCs) in an orthotopic glioblastoma mouse model. Our time course analysis demonstrated that MSCs display a rapid targeted migration to intracerebral U87 glioma xenografts growing in the contralateral hemisphere within the first 48h hours after application as assessed by histology and 7T magnetic resonance imaging. MSCs accumulated predominantly peritumorally but also infiltrated the main tumor mass and targeted distant tumor satellites while no MSCs were found in other regions of the brain. Intratumoral applicatio...

When host cells are invaded by viruses, they deploy multifaceted intracellular defense mechanisms to control infections and limit the damage they may cause. Host intracellular antiviral immunity can be classified into two main branches: (i) intrinsic immunity, an interferon (IFN)-independent antiviral response mediated by constitutively expressed cellular proteins (so-called intrinsic host restriction factors); and (ii) innate immunity, an IFN-dependent antiviral response conferred by IFN-stimulated gene (ISG) products, which are (as indicated by their name) upregulated in response to IFN secretion following the recognitio...

CONCLUSIONS: LZV and RZV are effective in preventing herpes zoster disease for up to three years (the main studies did not follow participants for more than three years). To date, there are no data to recommend revaccination after receiving the basic schedule for each type of vaccine. Both vaccines produce systemic and injection site adverse events of mild to moderate intensity. PMID: 31696946 [PubMed - in process]

AbstractAimTo identify clinical risk factors associated with herpes zoster (HZ) infections in systemic lupus erythematosus (SLE).MethodsA case ‐control study of HZ infection was performed in SLE patients seen at the University of Santo Tomas Lupus Clinics from 2009‐2014. Cases were matched 1:2 to SLE controls without HZ infection for age, sex, and disease duration. Clinical characteristics, SLE disease activity, and immunosuppressive u se were compared.ResultsSixty ‐five SLE patients (61, 93.8% female) who developed HZ were matched with 130 SLE patients without HZ. Mean age was 36.75 years (±1.35;P =...
