research 509 Using the human iPSCs-derived sensory neurons re-innervated skin ex vivo model to investigate mast cell-nerve fiber cross-talk in solar elastosis
In this study, UVB irradiation increased mast cell degranulation only when skin was innervated, suggesting that the interaction between mast cells and nerve fibres may exacerbate solar elastosis by promoting dysfunctional dermal elastic fiber accumulation, but further research is needed for confirmation.
