Youth is a state we want as much time as possible. The Japanese are innovative and eternally concerned about improving the quality of life. Not by accident are some of the most long-lived people on the planet.
Well, a new study published on Wednesday in the journal Nature announces that the Japanese have discovered a protein that could hinder the aging process of the skin.
The COL17A1 protein could be considered a genuine "fountain of eternal youth," as it could play an important role in the skin aging process, according to a study published on Wednesday in the journal Nature.
This protein encourages cellular competition, a process that allows powerful cells to prevail over the weakest.
However, age and ultraviolet rays cause an exhaustion of this protein in the body. This leaves the weaker cells to reproduce: the skin becomes finer, more fragile and needs a longer period of scarring.
The new study, published Wednesday in the journal Nature, was made on mice quills that share common features with human skin.
After understanding the importance of the COL17A1 protein, Japanese researchers from the Stem Cell Biology Department of the Tokyo University of Medicine and Dentistry, coordinated by Professor Emi Nishimura, tried to find a way to stimulate it with the aim of to prevent its exhaustion and thus, in theory, to inhibit aging and degradation of the skin.
Scientists have isolated two chemical compounds, which they tested successfully on skin cells, Agerpres writes.
"These treatments have favored the repair of the wounds in a significant manner," the authors of the study said.
Japanese researchers believe that these two compounds could in the future allow the discovery of a method for "facilitating skin regeneration and reducing aging."
In a commentary published by Nature magazine, two scientists who did not participate in this study recalled that the mechanism of cellular competition described in this research has so far been studied mainly on flies.
According to these experts, Professors Ganna Bilousova and James DeGregori of Colorado University in Denver, the study is based on the principle that the two identified chemical compounds could help combat the aging of the skin.
"Other studies are needed to decipher the mechanism of cellular competition for other types of tissues and to identify those compounds that are able to fight the aging of other organs," they added.
