That's because its surface
protein haemagglutinin doesn't contain many short amino acid sequences — called epitopes — that trigger helper T - cells in the body to stimulate antibody - making cells.
Direct anti-inflammatory effect of a bacterial virulence factor: IL -10-dependent suppression of IL - 12 production by
filamentous haemagglutinin from Bordetella pertussis.
HPAI A (H5N8) viruses cluster in the
same haemagglutinin (HA) clade as A (H5N1) viruses from Asia and A (H5N6)-- which has caused severe disease in humans in China — so the possibility of transmission from birds to humans can not be completely ruled out.
Soybeans also
contain haemagglutinin, a clot - promoting substance that causes red blood cells to clump together.
While rice doesn't have something as pernicious as the gluten lectin agglutinin, it does
feature haemagglutinin - lectin, which can bind to specific carbohydrate receptor sites in the intestinal lining and impede nutritional absorption.
«The flu vaccines that we use now work by raising immunity to a part of the influenza virus
called haemagglutinin, which is shortened to HA.
The enclosing fatty envelope (green) contains two types of protein,
haemagglutinin and neuraminidase (the «H» and «N» in the strain's codename), the levels of which determine the strain of virus.
Kawaoka's virus had a surface protein —
haemagglutinin (HA)-- from H5N1.
They reconstructed the virus, and changed one or two amino acids in
its haemagglutinin.
The team for the first time has demonstrated how a protein associated with the surface of virus,
haemagglutinin - neuraminidase, engages specific sugars to allow the virus to spread and cause infection.
«We have developed a compound that allows
the haemagglutinin - neuraminidase to form a similar intermediate, but reduces the ability of the virus to be released and consequently reduces any further infection.
«Effectively, the virus»
haemagglutinin - neuraminidase reacts with a carbohydrate to form an intermediate that then is hydrolysed, enabling the virus to escape from the infected cell surface and cause further infection.
«In this study, we used a multi-disciplinary approach to develop potent inhibitors that target a structural feature within the hPIV type 3
haemagglutinin - neuraminidase (hPIV - 3 HN).»
The strands, stretches of bases found in the genome of the rinderpest virus, carry the genes for manufacturing the «fusion protein» and the «
haemagglutinin protein».
Other problem areas include: phytates, which block the body's uptake of minerals; enzyme inhibitors, which hinder protein digestion; and
haemagglutinin, which causes red blood cells to clump together and inhibits oxygen take - up and growth.
Trypsin inhibitors and
haemagglutinin are growth inhibitors.
