Macrophage hitchhiking nanomedicine for enhanced β-elemene delivery and tumor therapy.

ABSTRACT: Nanoparticle-based drug delivery systems hold promise for tumor therapy; however, they frequently encounter challenges such as low delivery efficiency and suboptimal efficacy. Engineered living cells can redirect drug delivery systems to effectively reach targeted sites. Here, we used living macrophages as vehicles, attaching them with GeS nanosheets (GeSNSs) carrying β-elemene for transport to tumor sites. GeSNSs act as efficient sonosensitizers, enhancing ultrasound-induced reactive oxygen species generation for treating 4T1 breast tumors. Notably, macrophage hitchhiking delivery of β-elemene-loaded GeSNSs not only achieves high accumulation in tumor regions and suppresses tumor growth under ultrasound treatment, but also effectively remodels the immunosuppressive tumor microenvironment
