Dendritic Cell–Associated <scp>MARCKSL1</scp> Regulates Fibroblast Differentiation During Wound Healing

The study examines the role of MARCKSL1 in dendritic cells during wound healing, highlighting its importance in fibroblast differentiation and fibrotic remodeling. Using 20 male ICR mice, researchers found that MARCKSL1 expression is upregulated in response to TGF-β1, promoting fibroblast differentiation into myofibroblasts, crucial for wound contraction and fibrosis. Inhibition of MARCKSL1 with the MANS peptide reduced scar formation and collagen deposition, suggesting MARCKSL1 as a potential therapeutic target for anti-fibrotic wound healing. The study emphasizes the need for further research on MARCKSL1-high DCs and the specificity of the MANS peptide.
