Rabies is often seen as a deadly viral infection which is spread primarily through infected animal saliva.
This virus can be transmitted to any mammal although the most common transmission vectors are dogs, cats and bats in urban or rural areas.
One of the viruses most feared by humans recent studies have surprisingly shown that it could be the cure for cancer.
Scientists at Sungkyunkwan University in Suwon, South Korea, carried out arduous research in which they analyzed in detail, the ability of the Rabies virus to travel through nerve cells and infect brain tissue.
They focused their research in trying to repeat this process to transport nanoparticles and to destroy possible tumors. These small particles have the ability to destroy the soft tissues of the body through a laser.
"Nanoparticles traveled the same path as the Rabies virus through the central nervous system, which would make these proteins good candidates for the treatment of other cancers," says Dr. Youn, a research leader.
The body has a barrier called a Blood-Brain which prevents the entry of most of the pathogens that travel through the bloodstream.
The Rabies virus could be one of the agents that can cross this barrier.
For this reason, the scientists analyzed in depth, this route as an inspiration.
The team at Sungkyunkwan University in Suwon merged the gold nanoparticles with the physiognomy of the Rabies virus and devised spherical particles that allowed them to join with the receptors of the nerve cells, which serve as a gateway to the nervous system.
The peculiarity of these agents are their small gold bars that have the capacity to absorb the laser light and with the heat, they are able to destroy the surrounding tissue; according to an article published in Science.
Galo Soler Illia, PhD in Chemical Sciences at the University of Buenos Aires and director of the Institute of Nanosystems of UNSAM, explained the process of this technique:
"There are millions of cells in the body. Some of them may be ill, grow uncontrollably, not receive enough irrigation, etc.
In this case, nanocapsules can take action in which the remedy and sensors (antibodies, biomolecules) is introduced .
These bio-molecules recognize particular tissue types, organs, or cells that are diseased; observed on the outside. It is therefore possible to accurately direct it onto the appropriate cell.
There is an equivalent of a remote control that can be placed on the nanoparticle which can be activated from outside with a laser beam or a download (magnetic or electric). i.e. by using a gold particle which, when irradiated with a laser beam or an infrared, vibrating, Is heated locally and can expel molecules. "
Although this cure has not yet been deeply researched, it could be a starting point for future research to help improve the lives of people with cancer.
