RNF213 Is an Interferon‐Stimulated Gene That Targets Influenza A Virus NP and Activates MDA5 to Restrict Infection

Advanced Science, EarlyView.
RNF213 is characterized as a dual‐functional antiviral effector. It directly mediates the degradation of the influenza A virus nucleoprotein (NP) while simultaneously activating the MDA5‐mediated innate immune signaling pathway. This coordinated response establishes a powerful host defense system against viral infection. ABSTRACT Influenza A virus (IAV)

Applying valency-based immuno-selection to generate broadly cross-reactive antibodies against influenza hemagglutinins

Nature Communications
Conserved epitopes shared between virus subtypes are often subdominant, making it difficult to induce broadly reactive antibodies by immunization. Here, we generate a plasmid DNA mix vaccine that encodes protein heterodimers with sixteen different ...

Hemagglutinin sequence conservation guided stem immunogen design from influenza A H3 subtype [PDF]

, 2015
Seasonal epidemics caused by influenza A (H1 and H3 subtypes) and B viruses are a major global health threat. The traditional, trivalent influenza vaccines have limited efficacy because of rapid antigenic evolution of the circulating viruses.

The Hemagglutinin of Influenza A Virus Induces Ferroptosis to Facilitate Viral Replication

Advanced Science
AbstractFerroptosis is a novel form of cell death caused by the accumulation of lipid peroxides in an iron‐dependent manner. However, the precise mechanism underlying the exploitation of ferroptosis by influenza A viruses (IAV) remains unclear. The results demonstrate that IAV promotes its own replication through ferritinophagy by sensitizing cells to ...

Non-Steroidal Estrogens Inhibit Influenza Virus by Interacting with Hemagglutinin and Preventing Viral Fusion

International Journal of Molecular Sciences, 2023
Influenza virus is one of the main causes of respiratory infections worldwide. Despite the availability of seasonal vaccines and antivirals, influenza virus infections cause an important health and economic burden. Therefore, the need to identify alternative antiviral strategies persists.

Visualization of Endosomal Escape of Intracellularly Delivered Protein With Unexpected Photochemical Internalization of Trypan Blue

Advanced Science, EarlyView.
TB, a conventional cell viability dye, acts as both a fluorescence modulator (quenching GFP fluorescence upon protein binding and recovering it upon release) and a photosensitizer that triggers endosomal escape via photochemical internalization (PCI) under 590 nm light.

Glycomics-based analysis of chicken red blood cells provides insight into the selectivity of the viral agglutination assay [PDF]

, 2011
Agglutination of red blood cells (RBCs), including chicken RBCs (cRBCs), has been used extensively to estimate viral titer, to screen glycan-receptor binding preference, and to assess the protective response of vaccines.

Influenza virus hemagglutinin concentrates in lipid raft microdomains for efficient viral fusion [PDF]

Proceedings of the National Academy of Sciences, 2003
Lipid raft microdomains are enriched in sphingomyelin and cholesterol and function as platforms for signal transduction and as the site of budding of several enveloped viruses, including influenza virus. The influenza virus hemagglutinin (HA) glycoprotein, which mediates both viral-cell attachment and membrane fusion, associates intrinsically with ...

Lymphoid‐Tissue‐on‐Chip Recapitulates Human Antibody Responses In Vitro

Advanced Science, EarlyView.
The presented lymphoid‐tissue‐on‐chip system allows culture of primary human tonsil cells at organotypic high density under perfusion for up to 4 weeks, emulates immune response to soluble vaccines and vaccination via peripheral antigen‐presenting cells and represents a useful tool to assess cellular interactions during homeostasis, immune responses ...

Phylogeographic Dynamics of H9N2 Avian Influenza Viruses in Tunisia

Virus Research
Avian influenza virus subtype H9N2 is endemic in commercial poultry in Tunisia. This subtype affects poultry and wild birds in Tunisia and poses a potential zoonotic risk.
