Study confirms the arrival of herpes viruses to the brain through the nose

 
Recent American study showed that some herpes viruses can reach the brain through the nose and that these viruses are able to multiply, according to the magazine Science.
The researchers said the study authors, they found a type of herpes virus 6 in the human nasal cavity, adding that the virus uses these cells as a gateway through which to reach the blood-brain barrier.
The researchers said they studied under the supervision of Irene Harberts of the National Institute of Neurological Disorders in Bethesda, Maryland hypothesis that the virus reaches the brain through the nose like other viruses capable of infecting some kind of cells, some brain tissue.
The researchers explained that they, through experiments on the dead demonstrated the possibility of the emergence of the virus in all the brain, they found that it exists in particular in the center of smell brain, it was found the presence of the virus in the nasal mucosa in healthy people and patients with multiple sclerosis Multiple Sclerosis, as well as in patients who have no sense of smell . next to it has found the virus in more than 40 samples taken from the nose, but they did not find a relationship between the presence of virus in the nose of the owners of these samples from the infected hand, and on the other.
The researchers showed that HIV HP P-6 could be breeding in farms laboratory using a specific type of cells present in the nasal cavity and that this type of cells support the growth of new cells and it takes Bmahorha nervous and pass them from the nasal cavity to the brain, which made the researchers believe that viruses herpes exploit these cells to reach the brain.
It is worth mentioning that many of the viruses play a role in diseases resulting from setbacks disorders such as Alzheimer's or Parkinson's disease, linking scientists, for example, between infection Herbys human, who is also known as HPV and the development of inflammatory membrane of the brain, meningitis, multiple sclerosis of tissues and a forms of epilepsy is that the scientists did not know how to infiltration by the herpes virus 6 H 6 to H in the central nervous system of the brain so far.
