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.
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. The findings are “the first demonstration of T-cell-independent abscopal response,” co-corresponding author Edward Graves told BioWorld. “We’re not trying to say that all abscopal responses are macrophage-mediated. 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.”
A study led by Chinese radiologists at Peking University in Beijing has shown that positron emission tomography imaging of intercellular adhesion molecule-1 (ICAM-1) expression is a predictor for the abscopal effect, whereby nonirradiated cancers respond to radiotherapy.
