Abstract
Non-small-cell lung cancer (NSCLC) is the most prevalent type of lung cancer, and there is an urgent need for developing novel therapies. Sonodynamic therapy exhibits exceptional tissue penetration and minimal harm to healthy tissue, making it extremely promising for cancer treatment. The efficacy of SDT is limited by the intricate immunological microenvironment and the resistance to tumor treatment. This study developed targeted nanoparticles that use ultrasound to concentrate on treating NSCLC. The hybrid targeted nanoparticles utilize gold nanoparticles as their fundamental component, with the outside modified with engineered macrophage exosomes and the aptamer S11e to specifically target NSCLC. Ultrasound could effectively eliminate tumors in NSCLC cells by destroying lysosomes via targeted nanoparticles. Simultaneously, fragmented tumor antigens could effectively activate dendritic cell cells to recruit T cells. This method has significant efficacy in suppressing the development of NSCLC and exhibits potential for therapeutic application.
