Development of DNA-Biochip for Identification of Influenza A Virus Subtypes

Проблемы особо опасных инфекций, 2012
Developed was the DNA-biochip to identify subtypes of influenza A virus, pathogenic for humans. Microchip was capable of detecting H1, H3, H5-subtypes of hemagglutinin (including H1-subtype of pandemic A/H1N1(2009) influenza virus ) and neuraminidase ...

A Historical Perspective of Influenza A(H1N2) Virus

Emerging Infectious Diseases, 2014
The emergence and transition to pandemic status of the influenza A(H1N1)A(H1N1)pdm09) virus in 2009 illustrated the potential for previously circulating human viruses to re-emerge in humans and cause a pandemic after decades of circulating among animals.

Naturally Occurring Temperature-sensitive Influenza A Viruses of the H1N1 and H3N2 Subtypes

Journal of General Virology, 1980
Seventeen of twenty-six influenza A virus isolates of the H1N1 antigenic subtype and two of eleven H3N2 virus isolates from the 1977-78 season exhibited a ts phenotype, were restricted in plaquing in MDCK cells at 38.5 degrees C compared to 34 degrees C and appeared to be naturally occurring ts mutants.

Intensity and drivers of subtypes interference between seasonal influenza viruses in mainland China: A modeling study

iScience
Summary: Subtype interference has a significant impact on the epidemiological patterns of seasonal influenza viruses (SIVs). We used attributable risk percent [the absolute value of the ratio of the effective reproduction number (Rₑ) of different ...

Seroconversion to Pandemic (H1N1) 2009 Virus and Cross-Reactive Immunity to Other Swine Influenza Viruses

Emerging Infectious Diseases, 2011
To assess herd immunity to swine influenza viruses, we determined antibodies in 28 paired serum samples from participants in a prospective serologic cohort study in Hong Kong who had seroconverted to pandemic (H1N1) 2009 virus.

Pathogenesis of swine influenza virus (Thai isolates) in weanling pigs: an experimental trial

Virology Journal, 2009
Background The objective of this study is to investigate the pathogenesis of swine influenza virus (SIV) subtype H1N1 and H3N2 (Thai isolates) in 22-day-old SPF pigs. Results The study found that all pigs in the infected groups developed typical signs of

Complement-Independent Modulation of Influenza A Virus Infection by Factor H

Frontiers in Immunology, 2020
The complement system is an ancient innate immune defense mechanism that can recognize molecular patterns on the invading pathogens. Factor H, as an inhibitor of the alternative pathway, down-regulates complement activation on the host cell surface ...

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 ...

In Silico Characterization of Hemagglutinin Protein of Influenza a Virus [A/Canine/Beijing/Cau9/2009(H1N1] of H1N1 Subtype

JOURNAL OF ADVANCES IN BIOTECHNOLOGY, 2014
Using 3D-Jigsawn protein comparative modeling server, Verify-3D structure evaluation server, CHIMERA the homology modeling study of the mentioned protein was carried out and it holds the aim of the study. In this work, we in silico characterized the hemagglutinin protein of influenza A virus [A/canine/Beijing/cau9/2009(H1N1] (AEM89472).
