chickenpox/protease

Varicella-zoster virus (VZV), an alpha-herpes virus, is the causative agent of chickenpox, shingles, and postherpetic neuralgia. The three-dimensional crystal structure of the serine protease from VZV has been determined at 3.0-A resolution. The VZV protease is essential for the life cycle of the

Previous studies have shown that the herpes simplex virus 1 gene UL26 encodes a 635-amino acid protease that cleaves approximately 20 amino acids from the carboxyl terminus of itself and of a 329-amino acid product of the UL26.5 gene. The results of studies with a variety of protease inhibitors

Varicella-zoster virus (VZV) glycoprotein gpI, the homolog of herpes simplex virus gE, functions as a receptor for the Fc portion of immunoglobulin G. Like other cell surface receptors, this viral receptor is highly phosphorylated in cell culture. To identify the precise location of the cellular

Varicella zoster virus, the worldwide infectious human virus responsible for acute varicella and chickenpox, commonly spreads from exposure through contact with a skin lesion or airborne respiratory droplets. Keratinocytes, major targets and source of transmission of the virus present in the skin,

The present study aimed to explore the effects of a stabilizing ligand, Shield‑1, on the replication of recombinant varicella‑zoster virus (VZV) containing FK506 binding protein (FKPB) tags in essential open reading frames (ORF) 4 and 48. A specific galactokinase (galK) selection method was

The scaffolding protein and associated protease of the human herpesvirus varicella-zoster virus (VZV), encoded by genes 33.5 and 33 respectively, were synthesized in insect cells using a baculovirus expression system. The expressed 33.5 product formed numerous long, flexible, hollow rods, and in

Human cytomegalovirus (CMV) is a member of the Herpesviridae family of viruses that also includes herpes simplex viruses (HSV-1 and HSV-2), varicella-zoster virus (VZV), human herpes virus-6, 7, and 8 (HHV-6, HHV-7, and HHV-8), and Epstein-Barr virus (EBV). Each member of this family encodes a

Human herpes simplex virus type 1 (HSV-1) and type 2 (HSV-2) are responsible for herpes labialis (cold sores) and genital herpes, respectively. They encode a serine protease that is required for viral replication, and represent a viable target for therapeutic intervention. Here, we report the

Insulin degradation enzyme (IDE) is a 110-kDa zinc metalloprotease found in the cytosol of all cells. IDE degrades insulin and a variety of small proteins including amyloid-beta. Recently, IDE has been proposed as the receptor for varicella-zoster virus (VZV) attachment. During our reassessment,

The hemolytic uremic syndrome (HUS) and thrombotic thrombocytopenic purpura (TTP) are rare disorders characterized by thrombocytopenia, hemolytic anemia, and ischemic organ failure due to thrombotic occlusions in arterioles. The recent observation that a von Willebrand factor-cleaving protease

A novel anti-varicella-zoster virus compound, a derivative of pyrazolo[1,5-c]1,3,5-triazin-4-one (coded as 35B2), was identified from a library of 9,600 random compounds. This compound inhibited both acyclovir (ACV)-resistant and -sensitive strains. In a plaque reduction assay under conditions in

Human herpesviruses are responsible for a variety of diseases. They are divided into three subfamilies: alpha includes herpes simplex viruses (HSV-1 and HSV-2) and varicella-zoster virus (VZV); beta includes cytomegalovirus (CMV) and human herpesvirus-6 (HHV-6); and gamma includes Epstein-Barr virus

Varicella zoster virus (VZV) is the etiological agent of chickenpox and shingles, diseases characterized by epidermal skin blistering. Using a calcium-induced keratinocyte differentiation model we investigated the interaction between epidermal differentiation and VZV infection. RNA-seq analysis

Herpesviruses produce assembly proteins (AP) that act as scaffolding proteins for the assembly of the viral capsids. The products of the assemblin gene, which encodes both maturational protease and AP, have been established for herpes simplex virus type 1 (HSV-1) and human cytomegalovirus (CMV). We

The first step of herpesviruses virion assembly occurs in the nucleus. However, the exact site where nucleocapsids are assembled, where the genome and the inner tegument are acquired, remains controversial. We created a recombinant VZV expressing ORF23 (homologous to HSV-1 VP26) fused to the eGFP
