L-Ficolin Binds to the Glycoproteins Hemagglutinin and Neuraminidase and Inhibits Influenza A Virus Infection Both in vitro and in vivo [PDF]

Journal of Innate Immunity, 2012
L-ficolin, one of the complement lectins found in human serum, is a novel pattern recognition molecule that can specifically bind to microbial carbohydrates, thereby activating the lectin complement pathway and mounting a protective innate immune response. However, little is known about the role of L-ficolin during viral infections in vivo.

VIRUS-SPECIFIC HUMORAL IMMUNE RESPONSE ISOTYPIC STRUCTURE IN ADULT PATIENTS HOSPITALIZED WITH INFLUENZA A

Инфекция и иммунитет, 2016
The aim of this investigation was a comparative analysis of isotypic structure of specific antiviral systemic humoral immune response in hospitalized patients with influenza caused by virus A(H3N2) or A(H1N1), including the A(H1N1)pdm09. Paired acute and

The evolutionary pattern of glycosylation sites in influenza virus (H5N1) hemagglutinin and neuraminidase. [PDF]

PLoS ONE, 2012
Two glycoproteins, hemagglutinin (HA) and neuraminidase (NA), on the surface of influenza viruses play crucial roles in transfaunation, membrane fusion and the release of progeny virions.

Sequence variation in the haemagglutinin-neuraminidase gene of human parainfluenza virus type 3 isolates in the UK [PDF]

, 1995
The sequence variation in a 934 base-pair region of the gene encoding the haemagglutinin-neuraminidase of five human parainfluenza virus type 3 (HPIV3) isolates was determined together with that of a prototype UK strain. All of the clinical isolates were

A novel single virus infection system reveals that influenza virus preferentially infects cells in g1 phase. [PDF]

PLoS ONE, 2013
BackgroundInfluenza virus attaches to sialic acid residues on the surface of host cells via the hemagglutinin (HA), a glycoprotein expressed on the viral envelope, and enters into the cytoplasm by receptor-mediated endocytosis.

A polyvalent virosomal influenza vaccine induces broad cellular and humoral immunity in pigs

Virology Journal, 2023
Background Influenza A virus (IAV) is endemic in pigs globally and co-circulation of genetically and antigenically diverse virus lineages of subtypes H1N1, H1N2 and H3N2 is a challenge for the development of effective vaccines.

An Adenovirus-Vectored Influenza Vaccine Induces Durable Cross-Protective Hemagglutinin Stalk Antibody Responses in Mice

Viruses, 2017
Currently licensed vaccines against the influenza A virus (IAV) need to be updated annually to match the constantly evolving antigenicity of the influenza virus glycoproteins, hemagglutinin (HA), and neuramidiase (NA).

Nano‐ and Micro‐Sized Solid Materials Used as Antiviral Agents

Advanced Functional Materials, EarlyView.
Due to the rise of viral infections in humans and possible viral outbreaks, the use of nano‐ or micro‐sized materials as antiviral agents is rapidly increasing. This review explores their antiviral properties against RNA and DNA viruses, either as a prevention or a treatment tool, by delving into their mechanisms of action and how to properly assess ...

Evolutionary study and phylodynamic pattern of human influenza A/H3N2 virus in Indonesia from 2008 to 2010.

PLoS ONE, 2018
Influenza viruses are by nature unstable with high levels of mutations. The sequential accumulation of mutations in the surface glycoproteins allows the virus to evade the neutralizing antibodies.

Substitutions near the hemagglutinin receptor-binding site determine the antigenic evolution of influenza A H3N2 viruses in U.S. swine [PDF]

, 2014
Swine influenza A virus is an endemic and economically important pathogen in pigs, with the potential to infect other host species. The hemagglutinin (HA) protein is the primary target of protective immune responses and the major component in swine ...
