👥Biography 个人简介

Prof. Irving Weissman is the discoverer of cancer stem cells and a pioneer in innate immune checkpoint biology including CD47. He identified that cancer cells overexpress CD47 to send a 'do not eat me' signal to macrophages through SIRPalpha, providing the basis for anti-CD47 therapies in development. His research on combining CD47 blockade with phagocytosis-promoting antibodies has opened a new innate immunity checkpoint therapeutic category.
