The important role of macrophages in this process, especially the M2 subtype, has attracted attention as a potential target for macrophage-based immunotherapy. M2 macrophages have anti-inflammatory and reparative properties that enable them to modulate the immune response and facilitate repairing damaged tissues. They participate in reducing fibrogenic features in term of gene expression and histological markers associated with LF. These cells phagocytose apoptotic cells and matrix components. M2 macrophage-based immunotherapy has shown great potential in ameliorating LF through mechanisms involving the IL-10/STAT3 and TGF-β/SMAD signaling pathways, which are essential in suppressing the pro-inflammatory response and supporting tissue regeneration. However, significant challenges such as individual resistance to therapy and the potential for promoting fibrosis suggest that further development and research are needed to optimize the safety and efficacy of this therapy in clinical applications.
