What it means

MIT scientists have developed a nanoparticle-based method to reprogram natural killer (NK) immune cells directly inside the body, turning them into cancer-killing . This approach uses to deliver that instructs the cells to target tumors, eliminating the need to extract, engineer, and reinfuse cells. In mouse studies, the reprogrammed cells eliminated lymphoma tumors and also helped heal damaged livers, suggesting potential applications beyond cancer.

The claim is solid, based on a primary source: the MIT press release and the underlying peer-reviewed paper. The reporting in Science Daily closely follows the official release, and the search results confirm multiple outlets covering the same study, with consistent details about the nanoparticle technology and mouse-model results.
