A tiny anticancer weapon: Nano-sized particles trigger tumor cell self-destruction

A new twist on a decades-old anticancer strategy has shown powerful effects against multiple cancer types in a preclinical study from researchers in the Perelman School of Medicine at the University of Pennsylvania. The experimental approach, which uses tiny capsules called small extracellular vesicles (sEVs), could offer an innovative new type of immunotherapy treatment and is poised to move toward more advanced development and testing.
