Commercial serologic assays for varicella-zoster virus (VZV), which enable reliable determination of VZV immune status and are amenable to automation, are needed. The present study compares the automated performance of the VZV whole-cell enzyme-linked immunosorbent assay (ELISA) Enzygnost anti-VZV/IgG, the Euroimmun anti-VZV ELISA (IgG) based on highly purified viral proteins, and the VZV glyco...

Abstract Background: Varicella is a highly contagious and dangerous disease especially in immunocompromised patients. Children with cancer are at increased risk of severe illness and may fatal cases occur. Vaccination from VZV ( varicella zoster vaccine) infection can be safe, immunogenic, and effective in children with leukemia who meet the criteria and are at the risk of serious disea...

Varicella-zoster virus (VZV) causes chicken pox (varicella), becomes latent in dorsal root ganglia, and reactivates decades later to cause shingles (zoster). During latency, the entire VZV genome is present in a circular form, from which genes 21, 29, 62, and 63 are transcribed. Immediate-early (IE) VZV genes 62 and 63 encode regulators of virus gene transcription, and VZV gene 29 encodes a maj...

Varicella-zoster virus (VZV) is an alphaherpesvirus with the characteristic neurotropism of this group, but VZV also infects T cells productively and downregulates major histocompatibility complex (MHC) class I expression on infected T cells, as shown in the SCID-hu mouse model. T-cell tropism is likely to be critical for the cell-associated viremia associated with primary VZV infection. In the...

Varicella zoster virus (VZV) is a ubiquitous, exclusively human alphaherpesvirus. Primary infection usually results in varicella (chickenpox), after which VZV becomes latent in ganglionic neurons along the entire neuraxis. As VZV-specific cell-mediated immunity declines in elderly and immunocompromised individuals, VZV reactivates and causes herpes zoster (shingles), frequently complicated by p...

UNLABELLED Varicella-zoster virus (VZV) is a human neurotropic alphaherpesvirus and the etiological agent of varicella (chickenpox) and herpes zoster (HZ, shingles). Previously, inoculation of monkeys via the subcutaneous, intratracheal, intravenous, or oral-nasal-conjunctival routes did not recapitulate all the hallmarks of VZV infection, including varicella, immunity, latency, and reactivatio...

The transfer of antigen-specific cellular immunity in human bone marrow transplantation (BMT) was studied in 49 donor-recipient pairs, using a varicella-zoster-virus (VZV) specific lymphoproliferative response (LPR) assay. Posttransplant VZV-LPR could be serially measured in 31 long-term surviving recipients. VZV-specific T-cell immunity was detected in the early posttransplant period in 4 of 1...

Varicella-zoster virus (VZV) encodes five gene products that do not have homologs in herpes simplex virus. One of these genes, VZV open reading frame 32 (ORF32), is predicted to encode a protein of 16 kDa. VZV ORF32 protein was shown to be phosphorylated and located in the cytosol of virus-infected cells. Antibody to ORF32 protein immunoprecipitated 16- and 18-kDa phosphoproteins from VZV-infec...
