Discordant correlation between serological assays observed when measuring heterosubtypic responses against avian influenza H5 and H7 viruses in unexposed individuals [PDF]

, 2014
The human population is constantly exposed to multiple influenza A subtypes due to zoonotic spill over and rapid viral evolution driven by intrinsic error-prone replication and immunological pressure.

Avian and human receptor binding by hemagglutinins of Influenza A viruses

, 2006
An understanding of the structural determinants and molecular mechanisms involved in influenza A virus binding to human cell receptors is central to the identification of viruses that pose a pandemic threat.

Physico-chemical characterization of bacterial and hemagglutinins from the serum of the mud crab Scylla serrata [PDF]

Invertebrate Survival Journal, 2010
A naturally occurring hemagglutinin (HA), with activity against bacteria and yeast cells were detected in the serum of Scylla serrata using mammalian erythrocytes (RBC), various bacteria and yeast as indicator cells.

Correlation of Infectivity and Hemagglutinins of Reoviruses

Experimental Biology and Medicine, 1968
SummaryAll three reovirus prototypes were grown in MKTC; the infected cultures were maintained at 37° for up to 42 days. During this time period infectivity and HA of the reoviruses were periodically determined. The infectivity of all three types steadily declined to less than 1% of the maximal titer after 30 days.

Evaluation of the Subtype Specificity of Monoclonal Antibodies Raised against H1 and H3 Subtypes of Human Influenza A Virus Hemagglutinins

, 2002
Three previously described monoclonal antibodies (MAbs) specific for influenza A(H1) hemagglutinins (HA) revealed high sensitivity (98.2 to 99.1%) and specificity (100%) when tested against 245 strains of different subtypes.

A CASE OF ACQUIRED HEMOLYTIC ANEMIA

Iranian Journal of Public Health, 1979
The most common form of acquired hemolytic anemia is associated with what appears to be autologous IgG hemagglutinins. These anti-bodies may arise unexpectedly and in the absence of any recognizable underlying disease.

Acquisition of specific human respiratory tract binding by 2.3.4.4b H5N1 hemagglutinins requires multiple mutations

Journal of Virology
It has been suggested that the hemagglutinin of the human-infecting cattle-derived 2.3.4.4b virus A/Texas/34 H5N1 (H5TX) requires only one mutation, namely Q226L, to switch from binding avian-type to human-type receptor preference.

The production and development of H7 Influenza virus pseudotypes for the study of humoral responses against avian viruses [PDF]

, 2013
In recent years, high pathogenicity avian influenza (HPAI) virus, H5N1, low pathogenicity avian influenza (LPAI) virus, H9N2, and both HPAI and LPAI H7 viruses have proved devastating for the affected economies reliant on poultry industry, and have posed

Polymer-Stabilized Sialylated Nanoparticles: Synthesis, Optimization, and Differential Binding to Influenza Hemagglutinins

, 2020
During influenza infection, hemagglutinins (HAs) on the viral surface bind to sialic acids on the host cell’s surface. While all HAs bind sialic acids, human influenza targets terminal α2,6 sialic acids and avian influenza targets α2,3 sialic acids.
