Scientists understand how the mechanism of rejuvenation. Eternal youth is not far off?
Source:
Many people today in varying degrees, use the services of cosmetic medicine in the hope for as long as possible to preserve youthfulness. If not to take into account plastic surgery, even without them, thanks to the services of competent beauticians can be very long in appearance. But symptoms — it's only a "symptom", which lead the mechanisms of aging of skin and organism as a whole. And recently, scientists figured out how to influence them from inside.
revealed the mechanism of the prolongation of youth
Strangely enough, but in order to understand the mechanism of rejuvenation, scientists from Johns Hopkins University examined the hair follicles of mice. The fact that some types of rodents even after the deep wounds are able to recover your hair follicles. The skin formed in the place of the wounds, their properties are very similar to young. We're such a "bonus" deprived of and strong wound after healing we have formed a rough scar tissue.
«Understanding the biology underlying the cell damage may lead to this type of regeneration (Prim. as in mice), can open the way for the creation of cosmetic and therapeutic agents of a new generation», — said Luis Garza, doctor of medical Sciences, associate Professor Medical school at Johns Hopkins University.
The Researchers suggested that during this process answer double-stranded RNA molecules, which are released from damaged cells. Next, the scientists decided to check whether such a potential in human cells. But first we digress from the topic and to understand the effect of some of the most .
How to keep youth
One of the most popular ways of extending the youth of skin at the moment is laser therapy (correction of wrinkles with a special atraumatic laser) and drugs based on retinoic acid (they are thought to be revitalize cell frame). So, despite the fact that these methods are widely used in cosmetics, the mechanisms of their work is not fully understood. More precisely, was not clear until the moment when scientists from Johns Hopkins University began his research.

In his research, the experts studied the skin samples taken from 17 women . Patients there were 2 fence material — before and after studies.
It turned Out that the impact of the laser causes the formation of double-stranded RNA molecules (those that allow the mice to "grow" the skin) and increases the production of retinoic acid. Moreover, when cultures of cells separately treated with a solution of double-stranded molecules of RNA, generation of retinoic acid increased more than 10 times, and the cells began to resemble in structure the young.
"In the future, it is of great importance, because retinoic acid is already a tool for skin rejuvenation. But that's not all. Thanks to the discovery of the mechanisms of regeneration, we can create drugs that will help in the healing of deep wounds and recovering from burns."
