November 2024 in “International Journal of Biological Macromolecules” In this study, the researchers developed a cellulose nanofiber-based scaffold containing sitagliptin and zinc sulfide nanoparticles, which promoted scarless healing and hair follicle regeneration in rats by targeting DPP4+ fibroblasts, suggesting a novel approach for improved wound healing and skin regeneration.
April 2016 in “Journal of Investigative Dermatology” This study found that the peptide derivative beta-Ala-Pro-Dab-NHbenzyl may reduce wrinkles and sebum production in human skin by inhibiting dipeptidyl peptidase 4, suggesting potential for acne and skin inflammation treatment.
