Desialylation of Platelets by Pneumococcal Neuraminidase A Induces ADP-Dependent Platelet Hyperreactivity

open access: yesInfection and Immunity, 2018
Platelets are increasingly recognized to play a role in the complications of Streptococcus pneumoniae infections. S. pneumoniae expresses neuraminidases, which may alter glycans on the platelet surface.

Antigenic Drift of the Influenza A(H1N1)pdm09 Virus Neuraminidase Results in Reduced Effectiveness of A/California/7/2009 (H1N1pdm09)-Specific Antibodies

open access: yesmBio, 2019
The effectiveness of influenza vaccines against circulating A(H1N1)pdm09 viruses was modest for several seasons despite the absence of antigenic drift of hemagglutinin (HA), the primary vaccine component. Since antibodies against HA and neuraminidase (NA)

Modular Molecular Design and Self‐Assembled Nanostructures of Saccharide‑Appended Cyclic Dipeptides for Glycosidase‑Responsive Supramolecular Hydrogels

open access: yesSmall, EarlyView.
Saccharide‐appended cyclic dipeptides are designed and developed as building blocks for glycosidase‐responsive supramolecular hydrogels. Their aqueous self‐assembly enables β‐galactosidase‐triggered gel‐to‐sol and neuraminidase‐triggered sol‐to‐gel transition systems, highlighting their potential as glycosidase‐responsive soft materials for biomedical ...

A comparison of two anti‐neuraminidase monoclonal antibodies by complement activation

open access: yes, 1982
The specificities of two anti-neuraminidase monoclonal antibodies have been compared by their ability to fix complement. They were found to differ to some extent in their reactivity with a range of N2 influenza viruses.

Feathers and flu: identifying data gaps in avian influenza host dynamics to prioritize wildlife conservation Plumas y gripe: identificación de datos faltantes en la dinámica de hospedadores de la influenza aviar para priorizar la conservación de la vida silvestre

open access: yesWildlife Monographs, EarlyView.
We describe the host response continuum for highly pathogenic avian influenza viruses (HPAIV), including the continuum of host responses to HPAIV infection and exposure based on the primary axis of host competence, ability to infect other hosts, and host vulnerability.

A Novel Series of Sialic Acid-Based Influenza Virus Inhibitors that Target Influenza Virus Neuraminidase

open access: yes, 2019
Influenza virus continues to be a clinically-significant human pathogen that causes bothepidemics and pandemics. Successful inhibition of the viral neuraminidase hinders the release ofvirion progeny from the infected host cell and significantly reduces ...

Functional validation of a modified platelet desialylation test for immune and hereditary thrombocytopenias

open access: yesTransfusion Medicine, EarlyView.
Abstract Background Thrombocytopenia arises from heterogeneous inherited and acquired disorders, and identifying the underlying platelet clearance mechanisms remains challenging. Platelet desialylation, characterised by loss of sialic acid and consequent exposure of terminal β‐galactose residues recognised by the Ashwell–Morell receptor, represents an ...

Clinical application of a modified platelet desialylation test for mechanistic characterization of platelet transfusion refractoriness

open access: yesTransfusion, EarlyView.
Abstract Background Platelet transfusion refractoriness (PTR) is a major challenge in transfusion medicine and may result from both immune and non‐immune mechanisms. Although alloantibodies are well‐established contributors, Fc‐independent pathways such as platelet desialylation have emerged as alternative mechanisms of clearance.

Effectiveness of neuraminidase inhibitors in reducing mortality in patients admitted to hospital with influenza A H1N1pdm09 virus infection: a meta-analysis of individual participant data

open access: yesThe Lancet Respiratory Medicine, 2014
Summary Background Neuraminidase inhibitors were widely used during the 2009–10 influenza A H1N1 pandemic, but evidence for their effectiveness in reducing mortality is uncertain.
