Macrophage membrane-functionalized biomimetic Yiqi Huoxue formula nanoparticles improve atherosclerosis by regulating smooth muscle cell phenotypic transition via the KLF4/NF-κB pathway
MM/YQHXF-NPs can effectively prevent the transformation of SMCs into foam cells by inhibiting the KLF4 and NF-κB signaling pathways, thereby alleviating AS, and provide a theoretical basis for MM/YQHXF-NPs as a potential therapeutic drug for AS.
