The Use of Single Cell Mass Cytometry to Define the Molecular Mechanisms of Varicella-Zoster Virus Lymphotropism.

Front Microbiol 2020 26;11:1224. Epub 2020 Jun 26.

Department of Pediatrics, Stanford University, Stanford, CA, United States.

Unraveling the heterogeneity in biological systems provides the key to understanding of the fundamental dynamics that regulate host pathogen relationships at the single cell level. While most studies have determined virus-host cell interactions using cultured cells in bulk, recent advances in deep protein profiling from single cells enable the understanding of the dynamic response equilibrium of single cells even within the same cell types. Mass cytometry allows the simultaneous detection of multiple proteins in single cells, which helps to evaluate alterations in multiple signaling networks that work in tandem in deciding the response of a cell to the presence of a pathogen or other stimulus.

Zoster sine herpete: a review.

Korean J Pain 2020 Jul;33(3):208-215

Department of Pain Medicine, Affiliated Hospital of Zunyi Medical University, Zunyi, China.

Zoster sine herpete (ZSH) is one of the atypical clinical manifestations of herpes zoster (HZ), which stems from infection and reactivation of the varicella-zoster virus (VZV) in the cranial nerve, spinal nerve, viscera, or autonomic nerve. Patients with ZSH display variable symptoms, such as neuralgia, however, different from HZ, ZSH show no zoster, which makes clinical diagnosis difficult. ZSH not only causes initial symptoms, such as neuropathic pain in the affected nerve, Bell palsy, and Ramsay Hunt syndrome, but also postherpetic neuralgia and fatal complications such as VZV encephalitis and stroke.

Mouse Footpad Inoculation Model to Study Viral-Induced Neuroinflammatory Responses.

J Vis Exp 2020 Jun 14(160). Epub 2020 Jun 14.

Department of Molecular Biology, Princeton University.

This protocol describes a footpad inoculation model used to study the initiation and development of neuroinflammatory responses during alphaherpesvirus infection in mice. As alphaherpesviruses are main invaders of the peripheral nervous system (PNS), this model is suitable to characterize the kinetics of viral replication, its spread from the PNS to CNS, and associated neuroinflammatory responses. The footpad inoculation model allows virus particles to spread from a primary infection site in the footpad epidermis to sensory and sympathetic nerve fibers that innervate the epidermis, sweat glands, and dermis.

Varicella zoster virus in inflammatory bowel disease patients: what every gastroenterologist should know.

J Crohns Colitis 2020 Jun 27. Epub 2020 Jun 27.

Department of Gastroenterology & Hepatology, University Hospital Zurich.

Primary Varicella Zoster virus (VZV) infection results in varicella (chickenpox) while its reactivation results in herpes zoster (HZ; shingles). Patients with Inflammatory Bowel Disease (IBD) are susceptible to complications of primary VZV infection and have an increased risk of HZ. Concerns of VZV and HZ infection in the IBD population has been highlighted by the emergence of JAK-inhibitors and their safety profile in this patient population such as tofacitinib for the treatment of ulcerative colitis (UC).

HERQ-9 Is a New Multiplex PCR for Differentiation and Quantification of All Nine Human Herpesviruses.

mSphere 2020 Jun 24;5(3). Epub 2020 Jun 24.

Department of Virology, University of Helsinki, Helsinki, Finland

Infections with the nine human herpesviruses (HHVs) are globally prevalent and characterized by lifelong persistence. Reactivations can potentially manifest as life-threatening conditions for which the demonstration of viral DNA is essential. In the present study, we developed HERQ-9, a pan-HHV quantitative PCR designed in triplex reactions to differentiate and quantify each of the HHV-DNAs: (i) herpes simplex viruses 1 and 2 and varicella-zoster virus; (ii) Epstein-Barr virus, human cytomegalovirus, and Kaposi's sarcoma-associated herpesvirus; and (iii) HHV-6A, -6B, and -7.

Viral ribonucleotide reductase attenuates the anti-herpes activity of acyclovir in contrast to amenamevir.

Antiviral Res 2020 Aug 20;180:104829. Epub 2020 Jun 20.

Department of Virology, University of Toyama, Toyama, Japan.

Amenamevir is a helicase-primase inhibitor of herpes simplex virus (HSV) and varicella-zoster virus (VZV) and is used for the treatment of herpes zoster in Japan. The half maximal effective concentrations (ECs) of acyclovir and sorivudine for VZV increased as the time of treatment was delayed from 6 to 18 h after infection, while those of amenamevir and foscarnet were not affected. Susceptibility of infected cells at 0 and 18 h after infection was examined with four anti-herpes drugs, and the fold increases in EC for acyclovir, sorivudine, amenamevir, and foscarnet were 13.

Correlation of IgG autoantibodies against acetylcholine receptors and desmogleins in patients with pemphigus treated with steroid sparing agents or rituximab.

PLoS One 2020 18;15(6):e0233957. Epub 2020 Jun 18.

Department of Dermatology, Duke University School of Medicine, Durham, North Carolina, United States of America.

Introduction: Autoantibodies (autoAbs) against desmoglein-1 (DSG1) and desmoglein-3 (DSG3) have conventionally been studied and well accepted in the pathogenesis of pemphigus vulgaris (PV) and foliaceus (PF). Recent studies have suggested that non-DSG autoAbs may contribute to the pathogenesis of pemphigus, including autoAbs directed at acetylcholine receptors (AChR) and thyroid peroxidase (TPO). The purpose of this study is to retrospectively analyze PV and PF patient sera to better understand the relationship between anti-AChR and -TPO Abs to disease activity and DSG reactivity between patients treated with prednisone and steroid sparing agents (SSA; n = 22) or prednisone and rituximab (n = 21).
