Development of a C5-Azidoacetamide-Modified 4-Amino-2,3-Difluorosialic Acid Activity-Based Probe for Labeling of Influenza A Neuraminidases. [PDF]
We report DFSA5Az/DFSA5bio, C5‐azidoacetamide 4‐amino‐2,3‐difluorosialic acid activity‐based probes that trap influenza A viral (IAV) neuraminidases (NA) via a stabilized covalent Tyr‐sialosyl intermediate with hour‐scale reactivation. A bioorthogonal azide enables CuAAC (or one‐step biotin) tagging for activity‐dependent Western‐blot detection at ...

NAction! How Can Neuraminidase-Based Immunity Contribute to Better Influenza Virus Vaccines?
Neuraminidase is one of the two surface glycoproteins of influenza A and B viruses. It has enzymatic activity that cleaves terminal sialic acid from glycans, and that activity is essential at several points in the virus life cycle. While neuraminidase is

Microglia activated by microbial neuraminidase contributes to ependymal cell death
The administration of microbial neuraminidase into the brain ventricular cavities of rodents represents a model of acute aseptic neuroinflammation. Ependymal cell death and hydrocephalus are unique features of this model.

Vaccines are the primary intervention against influenza. Currently licensed inactivated vaccines focus immunity on viral hemagglutinin (HA). Self-amplifying mRNA (sa-mRNA) vaccines offer an opportunity to generate immunity to multiple viral proteins ...

Influenza Neuraminidase Inhibitors: Synthetic Approaches, Derivatives and Biological Activity
Despite being a common viral disease, influenza has very negative consequences, causing the death of around half a million people each year. A neuraminidase located on the surface of the virus plays an important role in viral reproduction by contributing

Multidrug-Resistant Pandemic (H1N1) 2009 Infection in Immunocompetent Child
Recent case reports describe multidrug-resistant influenza A pandemic (H1N1) 2009 virus infection in immunocompromised patients exposed to neuraminidase inhibitors because of an I223R neuraminidase mutation.

An Overview of Influenza Viruses and Vaccines
Influenza remains one of the major public health concerns because it causes annual epidemics and can potentially instigate a global pandemic. Numerous countermeasures, including vaccines and antiviral treatments, are in use against seasonal influenza ...

Influenza B virus (IBV) contributes to substantial influenza-mediated morbidity and mortality, particularly among children. Similar to influenza A viruses (IAV), the hemagglutinin (HA) and neuraminidase (NA) of IBV undergo antigenic drift, necessitating ...
