When attacking by influenza, some people can defeat influenza easily within a few days, but other people will last a long time, even die. As to this, German researchers find, this may relate to gene in the human body.
The researchers who German Helmholtz is infected with in the research center use different mice to carry on research. Director Krauss storehouse Harte of Sri Lankan of mouse's hereditary seminar of the experiment of this centre says: "A lot of people study influenza virus, but we hope to investigate host's response to virus. " In infecting the experiment, researchers find, the too drastic response of the immune system has caused the serious consequence that influenza lets the mouse be fatal.
In the experiment, researchers inject the same type, the same number of first type influenza virus into in 7 pieces of mouse's body, these mouse just like " Seven afterbirth fetus " ,Unanimous on the whole on the gene, but not all the same. Found finally, 5 mouse's colds among them did not have obvious symptom, the weight will drop, know the full restoration after but from 7 days to 8 days; And drop other 2 weight of mouse quickly,and several days after die.
Causing this kind of reason distinguished in order to find out, researchers have investigated how the immune system reacts to the virus. The storehouse Harte of Sri Lankan points out, the mouse dies from one's own immune defence, these immune defence should be protected mouse against and attacked in fact, but immune system has produce too many information, let immune cell become excessively active, immune cells have then killed the virus-infected lung and organized cells.
Researchers still find, virus dying in mouse's body is 100 times more than living virus that comes down in mouse's body. The storehouse Harte of Sri Lankan says: "Obviously, there is a particular receptor in the cells of the animal, make it receptive to a serious virus to infect. " He claims, it may be the same too that influenza of the human body is infected, the genetic factor may have great influence on function result of influenza virus.
