Researchers at McMaster University have developed a promising new cancer immunotherapy that uses cancer-killing cells genetically engineered outside the body to find and destroy malignant tumors.
The modified “natural killer” cells can differentiate between cancer cells and healthy cells that are often intermingled in and around tumors, destroying only the targeted cells.
The natural killer cells’ ability to distinguish the target cells, even from healthy cells that bear similar markers, brings new promise to this branch of immunotherapy, say members of the research team behind a paper published in the current issue of the journal iScience, newly posted on the PubMed database.
