Not only are Ebola's dead virus sticks, but they are also a water source for a new type of influenza virus. These flu virus viruses may also be able to attack the cells of humans and animals, researchers at the University of Zurich are now shown.
Influenza breeds are caused by a seasonal inflammation of a disease that can only be banned by people. Flu varieties that are spread in birds or pigs are not usually a danger to humans. However, in unusual cases, a virus or pneumonia virus can move to people – a process that has a zoonotic transplant – at the worst of which can cause a pandemic of the world with many illnesses and deaths .
Sticks as a reservoir for dangerous viruses
About six years ago, a new type of influenza virus was found in bats in South America. The flying mammals have already been a focus of virologists for a long time. This is because they carry many genres of viruses, and # 39; including viruses such as Ebola virus. However, it is not always clear whether swine flu viruses are also a danger to humans. The Zurich University University (UZH) international research team has now discovered that these new flu viruses can also have the potential to affect people and animals.
Global search for "entrance gate"
There were influenza viruses; Previously, which was connected to host cells through serial acids. These chemicals are found on the surface of almost all human beings and in different animals. This is one of the reasons why influenza infections can affect species that are very different, such as ducks, hens, pigs and humans. Unlike these viruses, swine flu viruses do not connect to stomachs, and that is why several research teams around the world started; find for the receptor by including human cells.
Bat viruses use molecul MHC-II to enter the cell
Silke Stertz and his team at UZH's Medical Research Institute have now been able to identify this login gateway. "The influenza viruses will use MHC-II molecules to enter the host cell," said the head of the survey. These folders are usually on the surface of special protection cells, and their obligation to differ between cells and structures of the body itself and those that are foreign. There are also some other virus types that enter your cells in this way.
Possible threat to humans and animals
"Surprisingly, we can not use the use of bone bone viruses by MHC-II collections of human organs, but also those with hens, pigs, mice and several bat species, "a & # 39; explains our PhD Out Karakus, the first author of the survey. Therefore, flu pneumonia viruses have the potential to include both people as well as stock, at least at a level of a & # 39; go into your cells. "That disease has not yet been observed. However, our findings show that these viruses are generally zonotic," and " adding to Silke Stertz. This reason is enough for the virologist UZH to continue to investigate the potentially hazardous viruses, especially in terms of migration and disruption. Traveling is the problem that is not restricted to South America.
