Crystallization of biologically active hemagglutinin-neuraminidase glycoprotein dimers proteolytically cleaved from human parainfluenza virus type 1.
We isolated, purified, and characterized the hemagglutinin-neuraminidase (HN) of human parainfluenza virus type 1, with the ultimate goal of producing crystals suitable for three-dimensional X-ray structure analysis. Pronase was used to cleave the globular head of the HN molecule directly from virus particles, forming HN monomers and dimers. The purified dimers retained neuraminidase and hemads...
متن کاملHemagglutinin-neuraminidase gene sequence-based reclassification of human parainfluenza virus 3 variants.
The most comprehensive phylogenetic classification of human parainfluenza virus 3 (HPIV-3) was recently developed [PLoS One 2012;7:e43893]. This classification included three distinct clusters (A, B and C) with subdivision of cluster C into four subclusters (C1-4). In the present report, the classification of HPIV-3 was refined by inclusion of 27 overlooked beside newly characterized Saudi vari...
متن کاملDistribution of Epstein-Barr Virus and Human Herpesvirus 8 Co-Infections among Human Immunodeficiency Virus -1 Positive Patients
Background and Aims: Among Human Immunodeficiency Virus (HIV)-infected individuals, Epstein-Barr virus (EBV) and Human Herpesvirus (HHV)-8 could cause significant illness as opportunistic infections. The purpose of the present study was to evaluate the prevalence of EBV and HHV-8 in saliva specimens obtained from HIV-1 infected Iranian individuals under the Highly Active Antiviral Therapy (HAAR...
متن کاملThe Enigma of Human T-Cell Leukemia Virus Type-1 (HTLV-1) Infection in Iran
Human T-cell lymphotropic virus type-I (HTLV-I) was the first human retrovirus associated with malignancy. The prevalence of HTLV-I infection varies significantly in different regions of the world. In this study, the prevalence of HTLV-I infection among ethnic Jews living in Shiraz, South of Iran, was investigated. 286 blood samples were obtained. HTLV-1 antibody assay on serum samples was d...
متن کاملStructure of the Parainfluenza Virus 5 (PIV5) Hemagglutinin-Neuraminidase (HN) Ectodomain
Paramyxoviruses cause a wide variety of human and animal diseases. They infect host cells using the coordinated action of two surface glycoproteins, the receptor binding protein (HN, H, or G) and the fusion protein (F). HN binds sialic acid on host cells (hemagglutinin activity) and hydrolyzes these receptors during viral egress (neuraminidase activity, NA). Additionally, receptor binding is th...
