Acute truncal ataxia in a healthy adult with varicella zoster virus cerebellitis: A case report and literature review.

J Neurol Sci 2019 May 2;400:186-187. Epub 2019 Apr 2.

Department of Neurology, Mayo Clinic, Rochester, MN 55905, USA.

Acute cerebellitis is a well recognized complication of varicella zoster virus (VZV) infection in children. It has been described in adults in the setting of virus reactivation with a preceding herpes zoster rash, but it is exceedingly rare in adults who are not elderly or immunocompromised, particularly in the absence of a rash. To our knowledge, there has been only one reported case of acute cerebellitis in an immunocompetent adult less than age 65 with virological confirmation of acute VZV infection. Read More

Zoster vaccination in older adults: efficacy and public health implications.

J Gerontol A Biol Sci Med Sci 2019 Apr 4. Epub 2019 Apr 4.

Health Sciences North Research Institute, Sudbury, ON, Canada.

Shingles and its most common disabling complication, post-herpetic neuralgia (PHN), represents a serious public health challenge in the older population. The decline in the T-cell-mediated immune response to Varicella Zoster Virus after age 50 is clearly associated with increased risk of viral reactivation, causing an acutely painful zoster rash which may have a severe prodrome of dermatomal pain and persist as seriously debilitating PHN well beyond the resolution of the rash. However, new vaccines and adjuvants are being developed and trialed, and are now more effective in preventing shingles and the sequelae of PHN. Read More

Varicella zoster virus productively infects human peripheral blood mononuclear cells to modulate expression of immunoinhibitory proteins and blocking PD-L1 enhances virus-specific CD8+ T cell effector function.

PLoS Pathog 2019 03 14;15(3):e1007650. Epub 2019 Mar 14.

Department of Neurology, University of Colorado School of Medicine, Aurora, Colorado, United States of America.

Varicella zoster virus (VZV) is a lymphotropic alpha-herpesvirinae subfamily member that produces varicella on primary infection and causes zoster, vascular disease and vision loss upon reactivation from latency. VZV-infected peripheral blood mononuclear cells (PBMCs) disseminate virus to distal organs to produce clinical disease. To assess immune evasion strategies elicited by VZV that may contribute to dissemination of infection, human PBMCs and VZV-specific CD8+ T cells (V-CD8+) were mock- or VZV-infected and analyzed for immunoinhibitory protein PD-1, PD-L1, PD-L2, CTLA-4, LAG-3 and TIM-3 expression using flow cytometry.

Laboratorio de Glicobiología Humana y Diagnóstico Molecular; Centro de Investigación en Dinámica Celular, Instituto de Investigación en Ciencias Básicas y Aplicadas, Universidad Autónoma del Estado de Morelos. Av. Universidad 1001, Cuernavaca, México.

Certain viral infections are known to modify the glycosylation profile of infected cells through the overexpression of specific host cell fucosyltransferases (FUTs). Infection with CMV (cytomegalovirus), HCV (hepatitis C virus), HSV-1 (herpes simplex virus type-1) and VZV (varicella-zoster virus) increase the expression of fucosylated epitopes, including antigens sLex (Siaα2-3 Galβ1-4(Fucα1-3)GlcNAcβ1-R) and Ley (Fucα1-2 Galβ1-4(Fucα1-3)GlcNAcβ1-R). The reorganization of the glycocalyx induced by viral infection may favor the spread of viral progeny, and alter diverse biological functions mediated by glycans, including recognition by the adaptive immune system.

Varicella-zoster virus as a causative agent of acute retinal necrosis in younger patients.

Chin Med J (Engl) 2019 Mar;132(6):659-663

Department of Ophthalmology, Peking Union Medical College Hospital, Chinese Academy of Medical Sciences, Beijing 100730, China.

Background: Herpes virus is considered to be the pathogen of acute retinal necrosis (ARN) infection. Previous studies have found that patients with ARN caused by the varicella-zoster virus (VZV) are often older, and patients with herpes simplex virus (HSV) induced ARN are considerably younger. However, in our clinical work, we find that VZV is also a pathogen in younger ARN patients. Read More

Varicella Zoster Virus Alters Expression of Cell Adhesion Proteins in Human Perineurial Cells Via Interleukin 6.

J Infect Dis 2019 Mar 5. Epub 2019 Mar 5.

Department of Neurology, University of Colorado School of Medicine, Aurora.

Background: In temporal arteries (TAs) from giant cell arteritis patients, varicella zoster virus (VZV) is seen in perineurial cells that surround adventitial nerve bundles and form the peripheral nerve-extrafascicular tissue barrier (perineurium). We hypothesized that during VZV reactivation from ganglia, virus travels transaxonally and disrupts the perineurium to infect surrounding cells.

Methods: Mock- and VZV-infected primary human perineurial cells (HPNCs) were examined for alterations in claudin-1, E-cadherin and N-cadherin. Read More
