London, September 10 (Xinhua) ' The reporter is yellow) British researchers say on the 10th, compared with ordinary influenza virus, first type H1N1 influenza virus has stronger ability to affix to cell, can bind with cell of the lung depths and produce katogene directly. This research results contribute to explaining why spread ability of first type influenza virus is relatively stronger. Influenza virus needs affixing to receptor molecule in the surface of cell first, could further encroach on cells and initiate and infect. Different virus have adhering to receptoring different, if virus find the corresponding receptor at cell that adhere to their, the virus is unable to invade this cell. The researchers of British kingdom Institute of Technology publish the article and say, they trained 86 kinds of different adhering to the receptor in the test tube on the 10th, what receptors are adhering to the target of influenza virus in order to be measured. Found finally, ordinary influenza virus studied can only be on the receptor attached to nasal cavity, throat and other upper respiratory tract cells, first type influenza virus can also be affixed to receptor of lung depths cells. Researchers say, first type influenza virus is wider when adhering to the range, prove its spread ability is stronger. It can affix to cell of the lung depths directly, this can explain why lung that a few patients appear is infected, worsen the lung initiated to infect much more seriously more than ordinary influenza condition. However, the intensity that first type influenza cells affix to lung cell, want the intensity that this weaker than virus affixes to upper respiratory tract cell, this contributes to explaining why most first type influenza patients' symptom is minor. Researchers remind and say, in the future once first type influenza virus will morph, become stronger to the cell adhesion of lung, will lead to the fact more people will be infected with the serious lung. So, the medical circle should maintain sharp vigilance to the variation that first type influenza virus may present.
