research Hydrogel microneedle delivery of a palmitoylated peptide promotes hair regeneration via dual activation of Wnt/β-catenin and cAMP–PKA signaling
The study developed a palmitoylated peptide, Pal-MPAPO, incorporated into a hyaluronic acid-based hydrogel microneedle system for effective transdermal delivery to promote hair regeneration. The microneedles demonstrated sufficient mechanical strength for skin insertion and enabled prolonged release of the peptide. In human dermal papilla cells, Pal-MPAPO activated the Wnt/β-catenin pathway and increased cAMP levels primarily through VPAC1, with no significant role for VPAC2. Molecular interactions were confirmed through various simulations and imaging techniques. In a C57BL/6 mouse model, the Pal-MPAPO-loaded microneedles significantly enhanced hair regrowth, showing similar efficacy to minoxidil but requiring less frequent application. This suggests Pal-MPAPO as a promising candidate for hair regeneration with the hydrogel microneedle system offering a targeted delivery method.
