Researchers find first flows the virus meets the human reason
Xinhua News Agency Washington 8 Cable of the 5th of moon (reporter Ren HaiJun) A research group composed of country's scientists such as U.S.A. and Japan,etc. says on the 5th, they find first type H1N1 influenza virus can meet the human body and high-efficient reason that duplicate.
Generally speaking, influenza virus should realize that enter mammalian body including people and pay and duplicate from the constellation chief cell effectively, need to have two kinds of amino acids on the particular position of its PB2 protein - -2,6-diaminocaproic acid and Radix Asparagi amide acid . For a long time, researchers have not found these two kinds of amino acids in first has flowed in this particular position of virus PB2 protein, so to first type H1N1 Feel obscure to can spread among persons in influenza.
The research group finds, the virus is 4 kinds of bird flu and pig's influenza virus appearing in the past 90 years that first flows " L Hybridize " R Product,include even it remnants partly of 1918 Spanish influenza virus, its 2,6-diaminocaproic acid exists in PB2 Another special position of protein. First flows such special structure of virus enables it to well adapt to human cells, thus duplicate in the human body effectively.
Researchers say, this discovery has offered another usable hereditary mark for predicting influenza in the future is great and prevailing. This research results are issued in newest U.S.A. >On the magazine .
