Varicella-zoster virus (VZV) is an alphaherpesvirus that is the causative agent of chickenpox and herpes zoster. VZV open reading frame 5 (ORF5) encodes glycoprotein K (gK), which is conserved among alphaherpesviruses. While VZV gK has not been characterized, and its role in viral replication is unknown, homologs of VZV gK in herpes simplex virus type 1 (HSV-1) and pseudorabies virus (PRV) have...

Both immunoglobulin M (IgM) and IgG antibodies to varicella-zoster virus (VZV) were detectable in a solid-phase radioimmunoassay with 125I-labeled goat antisera to human immunoglobulins. Primary infection with VZV was associated with early production of IgM and IgG antibodies and rapid development of lymphocyte transformation to VZV antigen. Among eight subjects with varicella tested 1 to 4 day...

Many characteristics of the putative protein encoded by varicella-zoster virus (VZV) open reading fram (ORF) 14 indicate that it is a glycoprotein, which has been designated gpV. To identify the protein products of the gene, the coding sequences were placed under the control of the vaccinia virus p7.5 promoter and recombinant vaccinia viruses were constructed. Heterogeneous polypeptides with mo...

Background: Varicella–zoster virus (VZV) causes herpes zoster and varicella (Chicken-pox), usually a mild disease which is diagnosed clinically with few complications. However, in neonates and healthy adults it can have a severe presentation. Herpes zoster results from VZV reactivation later in life. Objective: To determine the seroprevalence of VZV in elementary school children aged 6-10 years...

Background and Aims: Varicella-zoster virus (VZV) infection during pregnancy can treat the health of mother and fetus. The present study was aimed to determine the prevalence of VZV IgG antibodies among pregnant women living in Yazd, Iran. Materials and Methods: In this cross-sectional, all pregnant women referred to Baghayipour clinic of Yazd city were participated. IgG Antibodies against VZV...

Varicella-zoster virus (VZV) vasculopathy produces stroke, giant cell arteritis, and granulomatous aortitis, and it develops after virus reactivates from ganglia and spreads transaxonally to arterial adventitia, resulting in persistent inflammation and pathological vascular remodeling. The mechanism(s) by which inflammatory cells persist in VZV-infected arteries is unknown; however, virus-induc...

Background and Objectives: Chicken pox has potential complications during pregnancy for both the mother and her baby. The aim of this study was to determine the Varicella-zoster virus (VZV) immune status in pregnant women in Babol and its surrounding neighborhoods. Materials and Methods: This seroepidemiological study was carried out on 427 pregnant women referred to Rohani Hospital, Babol, no...

Varicella zoster virus (VZV) becomes latent in human ganglia after primary infection. VZV reactivation occurs primarily in elderly individuals, organ transplant recipients, and patients with cancer and AIDS, correlating with a specific decline in cell-mediated immunity to the virus. VZV can also reactivate after surgical stress. The unexpected occurrence of thoracic zoster 2 days before space f...

Under conditions of naturally acquired primary varicella-zoster virus (VZV) infection, the first response of the naive host is mediated by the innate immune system through antiviral cytokines and the activation of NK cells [1]. These responses are likely to be important for the initial control of VZV at mucosal sites of inoculation and to trigger the induction and amplification of adaptive, VZV...
