New genetic experiment was found to shrink woman's pancreatic cancer
strengthen T cells to fight some types of leukemia and lymphoma. They add an artificial receptor to patients’ T cells so the immune fighters can recognize a marker on the outside of blood cancer cells, and attack.But that CAR-T therapy doesn’t work against more common solid tumors, which don’t carry that same danger marker.The new twist: At Oregon’s Providence Cancer Institute, researcher Eric Tran genetically engineered Wilkes’ T cells so they could spot a mutant protein that's hidden inside her tumor cells -- and only there, not in healthy cells.How? Certain molecules sit on the surface of cells and give the immune system a sneak peek of what proteins are inside.
