Macrophage-biomimetic nanomedicine for targeted therapy of abdominal aortic aneurysm via Nrf2/NF-κB pathway.

ABSTRACT: Rationale: Abdominal aortic aneurysm (AAA) is a significant cause of death worldwide, with both mortality and incidence rates gradually increasing. Its complex pathological mechanisms hinder drug development. This work aims to develop a biomimetic multifunctional nanoparticle for targeted AAA therapy. Methods: Leveraging the multi-pore property of mesoporous Prussian blue nanoparticles (MPB NPs), we encapsulated the rosiglitazone (RLZ) into MPB NPs to synthesize MPB-RLZ NPs. Then, macrophage-biomimetic nanoparticles (MPB-RLZ@MM NPs) were prepared by coating MPB-RLZ NPs with macrophage membranes (MM). The characterization and reactive oxygen species (ROS)-scavenging ability of MPB-RLZ@MM NPs were evaluated. Next, the biocompatibility and biological functions of MPB-RLZ@MM NPs
