The underlying skin cells that make cell fat, the process that leaves the wrinkles over the years, is a "secret skin" that continues to be the skin of youngsters., indicates a final exam.
"Why do we stop skin loss for many years," says Richard Gallo, head of California Department of Dermatology in California, in San Diego (UCSD) and author of the study.
Research, published in the scientific journal Immunology, was discovered as a dermis cell fibroblasts They are capable of converting fatty tissue into the skin and look like a young person.
Similarly, fibroblasts produce a peptide (the unity of a few amino acids), "it plays an important role in the fight against infections," said a study by a group of UCSDs.
"Fibroblasts cause fat loss to convert fat into skin facial infections and may affect skin aging"explained the researcher.
Gallo says that this process is unique and that it is typical of certain fibroblasts, so gaining weight is not a solution to achieve this fatty tissue, which helps the skin to look great and fight against infections.
On the contrary, he adds, "obesity affects the ability to fight infections."
Research details are proteins TGF-betaIt controls many of the functions of the cell, "preventing fibroblasts from becoming fat and preventing the production of cathelicidine" against antimicrobial peptides that protect against bacterial infections. "
"Children have a lot of skin fat, especially good for dealing with certain types of infections," he added, according to age, that fibroblasts will lose their ability to become fat.
"Under the layer of fat is a much younger look and, over the years, the loss of skin fat is very high," he says.
Laboratory mice are used Chemical blocks to inhibit "aging" action With TGF-Beta, which recovered a "wrinkle" skin look fresh.
The same result occurred when the TGF-Beta function was blocked by genetic action techniques, which made it possible for researchers to "stop aging".
The researchers stressed the importance of recovering the appearance of young people, but protecting skin infections that endanger the life of older people.
