The inducible amphisome isolates viral hemagglutinin and defends against influenza A virus infection [PDF]
Nature Communications, 2020 AbstractThe emergence of drug-resistant influenza type A viruses (IAVs) necessitates the development of novel anti-IAV agents. Here, we target the IAV hemagglutinin (HA) protein using multivalent peptide library screens and identify PVF-tet, a peptide-based HA inhibitor.

An Open Receptor-Binding Cavity of Hemagglutinin-Esterase-Fusion Glycoprotein from Newly-Identified Influenza D Virus: Basis for Its Broad Cell Tropism. [PDF]
, 2016 Influenza viruses cause seasonal flu each year and pandemics or epidemic sporadically, posing a major threat to public health. Recently, a new influenza D virus (IDV) was isolated from pigs and cattle. Here, we reveal that the IDV utilizes 9-O-acetylated

Cytomegalovirus is associated with depression and anxiety in older adults [PDF]
, 2008 Infection with cytomegalovirus (CMV), a β-herpesvirus, is common within the population. Although asymptomatic, infection is associated with increased serum concentrations of cytokines such as TNFα and IL-6, which are also related to mood and wellbeing ...

Hemagglutinin Spatial Distribution Shifts in Response to Cholesterol in the Influenza Viral Envelope [PDF]
Biophysical Journal, 2015 Influenza virus delivers its genome to the host cytoplasm via a process of membrane fusion mediated by the viral hemagglutinin protein. Optimal fusion likely requires multiple hemagglutinin trimers, so the spatial distribution of hemagglutinin on the viral envelope may influence fusion mechanism.

Long-lasting cross-protection against influenza A by neuraminidase and M2e-based immunization strategies [PDF]
, 2016 There is mounting evidence that in the absence of neutralizing antibodies cross-reactive T cells provide protection against pandemic influenza viruses. Here, we compared protection and CD8+ T cell responses following challenge with H1N1 2009 pandemic and

Influenza hemagglutinin drives viral entry via two sequential intramembrane mechanisms [PDF]
Proceedings of the National Academy of Sciences, 2020 Abstract Enveloped viruses enter cells via a process of membrane fusion between the viral envelope and a cellular membrane. For influenza virus, mutational data have shown that the membrane-inserted portions of the hemagglutinin protein play a critical role in achieving fusion. In contrast to the relatively well-understood ectodomain, a

Evolution of the G+C content frontier in the rat cytomegalovirus genome [PDF]
, 2008 Within the 230138 bp of the rat cytomegalovirus (RCMV) genome, the G+C content changes abruptly at position 142644, constituting a G+C content frontier. To the left of this point, overall G+C content is 69.2%, and to the right it is only 47.6%.

Polymer-stabilized sialylated nanoparticles : synthesis, optimization, and differential binding to influenza hemagglutinins [PDF]
, 2020 During influenza infection, hemagglutinins (HAs) on the viral surface bind to sialic acids on the host cell's surface. While all HAs bind sialic acids, human influenza targets terminal α2,6 sialic acids and avian influenza targets α2,3 sialic acids.
