Glycyrrhizin exerts antioxidative effects in H5N1 influenza A virus-infected cells and inhibits virus replication and pro-inflammatory gene expression. [PDF]

, 2011
Glycyrrhizin is known to exert antiviral and anti-inflammatory effects. Here, the effects of an approved parenteral glycyrrhizin preparation (Stronger Neo-Minophafen C) were investigated on highly pathogenic influenza A H5N1 virus replication, H5N1 ...

Newcastle disease virus in Egyptian domestic poultry, 2019–2021: Molecular characterization, phylogenetic analysis, and coinfection with avian influenza A virus

Open Veterinary Journal
Background: Newcastle Disease Virus (NDV) is a major viral disease of poultry that causes outbreaks in chickens in Egypt. Aim: The aim of this study was to determine the prevalence and molecular characteristics of NDV and its cocirculation with avian

Integrating genotypes and phenotypes improves long-term forecasts of seasonal influenza A/H3N2 evolution

eLife, 2020
Seasonal influenza virus A/H3N2 is a major cause of death globally. Vaccination remains the most effective preventative. Rapid mutation of hemagglutinin allows viruses to escape adaptive immunity. This antigenic drift necessitates regular vaccine updates.

Impact of Protein Nitration on Influenza Virus Infectivity and Immunogenicity

Microbiology Spectrum, 2022
Influenza viruses are deadly respiratory pathogens of special importance due to their long history of global pandemics. During influenza virus infections, the host responds by producing interferons, which activate interferon-stimulated genes (ISGs ...

Neurogenic pulmonary edema following febrile status epilepticus in a 22-month-old infant with multiple respiratory virus co-detection: a case report

BMC Infectious Diseases, 2020
Background Neurogenic pulmonary edema is a rare but serious complication of febrile status epilepticus in children. Comprehensive screening for viral pathogens is seldomly performed in the work-up of febrile children.

Influenza virus and atherosclerosis [PDF]

QJM: An International Journal of Medicine, 2019
AbstractInfluenza viruses infect the upper respiratory system, causing usually a self-limited disease with mild respiratory symptoms. Acute lung injury, pulmonary microvascular leakage and cardiovascular collapse may occur in severe cases, usually in the elderly or in immunocompromised patients. Acute lung injury is a syndrome associated with pulmonary

The role of influenza neuraminidase transmembrane domain on budding and virus morphology [PDF]

, 2014
Influenza A virus neuraminidase (NA), a type II transmembrane glycoprotein plays a role in the cleavage of sialic acids and facilitating the release of mature virions from the surface of infected cells. NA has also previously been shown to play a role in

IgA polymerization contributes to efficient virus neutralization on human upper respiratory mucosa after intranasal inactivated influenza vaccine administration

Human Vaccines & Immunotherapeutics, 2018
Unlike the current injectable influenza vaccines, intranasally administered influenza vaccines induce influenza virus-specific IgA antibodies in the local respiratory mucosa as well as IgG antibodies in the systemic circulation. Our previous study showed

Influenza virus infections [PDF]

Postgraduate Medical Journal, 1973
Summary Ninety-six strains of influenza A and 113 influenza B were found in the two MRC/PHLS surveys. In the general practitioner survey the majority of strains were isolated from cases diagnosed as influenza but in hospital most came from cases diagnosed as having other respiratory infections.

Insights into neutralization of animal viruses gained from study of influenza virus [PDF]

, 1991
It has long been known that the binding of antibodies to viruses can result in a loss of infectivity, or neutralization, but little is understood of the mechanism or mechanisms of this process.
