Skin loses the ability to form fat during aging.
Affects how the skin fights infections and influence the skin's appearance.
Identified a protein (transforming growth factor beta, TGF-B) that stops dermal fibroblasts from converting into fat cells.
Also prevents cells from producing the antimicrobial peptide cathelicidin, which helps protect against bacterial infections.
Inhibiting the TGF-β pathway causes the skin to revert back to a younger function (in mouse models).
The study was published in the Immunity journal.
