A H1N1 virus has a biochemical trick

• April 16, 2024

The influenza A H1N1 virus , which caused the last pandemic in 2009, used an innovative biochemical trick that allows it to change shape and evade the host's immune systems, which makes it spread effectively in humans, according to the publication of August 2010 of the Public Library of Science Pathogens. The international team that carried out the research expands the repertoire of known factors that cause the influenza virus and discovered that the virus can sequester the host cell and amplify the infection in mammals including humans, says the portal Science Daily. This is the reason why the virus replicates so well in humans . The discovery reveals another genetic indicator that may be helpful in preventing new pandemics. The influenza A H1N1 virus caused a pandemic worldwide in 2009 and 2010, reaching to affect more than 30 million people. The A H1N1 virus is the combination of 4 different viruses that come from birds and pigs, same that made its appearance in the last 90 years and still preserves genetic remains of the influenza pandemic that was unleashed in 1918 which killed more than 20 million people, indicates Yoshirihiro Kawaoka, professor of biopathological sciences at the University of Wisconsin (Madison's School of Veterinary Medicine) Lysine, an essential amino acid, resides in a completely different place in the protein, which causes it to be responsible for the virus's ability to adapt better in human cells , indicates Kawaoka.
