TGFB1 and neoplasm: Multiple technological platforms show potential for regulating this process: magnetic nanocarrier Fe3O4–SAS@PLT enables precise delivery of sulfasalazine to lesions [623]; combined regimens incorporating tumor‐derived microparticles, radiotherapy, PD‐1 antibodies, and TGF‐β inhibitors effectively reverse M2 polarization [624]; synergistic application of oxygen‐elevating photosensitizers and FINs significantly enhances LPO while promoting IFN‐γ secretion and immune microenvironment remodeling [625, 626].
