However, during skin fibrosis, this adaptability becomes detrimental as adipocytes undergo lipid depletion associated with disease pathology. We previously identified the WNT signalling pathway\u2014acting through Dipeptidyl Peptidase IV (DPP4) \u2013 as a key mediator of lipid depletion associated with skin fibrosis, but the mechanism remains unclear. DPP4 is an exopeptidase that cleaves a wide array of substrates across different cell types. Here, we investigate whether modulation of lipid\u2010regulating DPP4 substrates is sufficient to preserve lipid content in WNT\u2010activated dermal adipocytes. Using two complementary strategies, we found that supplementation with the DPP4 substrates Neuropeptide Y (NPY) and Glucose\u2010dependent Insulinotropic Peptide (GIP) can partially protect lipid content in dermal adipocytes. When used in combination, we found that the protection against lipid depletion was more effective than monotherapy alone. These findings demonstrate that supplementation with DPP4 substrates provides a basis for targeted treatments for lipodystrophy syndromes and skin fibrosis.<\/jats:p>","DOI":"10.1111\/exd.70354","type":"journal-article","created":{"date-parts":[[2026,8,27]],"date-time":"2026-08-27T04:56:44Z","timestamp":1787806604000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["DPP4
