Core Viewpoint - The article discusses a promising strategy for inhibiting tumor metastasis by targeting tumor extracellular vesicles (TEV) through a newly developed lipidated nanophotosensitizer that can track and disable TEV, effectively suppressing both tumor growth and metastasis [2][4][8]. Group 1 - The research team from Southern Medical University has published a study in Nature Cancer, focusing on the concurrent inhibition of tumor growth and metastasis using a lipidated nanophotosensitizer [3]. - The developed lipidated nanophotosensitizer can efficiently track and destroy TEV, leading to a dual effect of inhibiting tumor growth and metastasis [4][8]. - The study utilized engineered palmitic acid surface-displaying nanoparticles that are effectively taken up by tumor cells and can actively track TEV, combining their distribution within tumor cells and TEV [6]. Group 2 - Upon near-infrared light exposure to the primary tumor site, reactive oxygen species (ROS) are generated both inside tumor cells and within TEV, resulting in photodynamic inhibition of the primary tumor and blocking intercellular communication by inhibiting TEV [6]. - The research demonstrated effective suppression of tumor growth and metastasis in various tumor models in female mice [6].
