A combination of radiation therapy and CD47 blockade induced an abscopal effect in animal studies even in animals that lacked T cells, researchers reported in the Nov. 21, 2022, online issue of Nature Cancer.

There are plenty that require T cells,” Graves clarified. But “there is another avenue of abscopal responses that has not been reported. ... All the abscopal literature is about stimulating an adaptive response.”
