Researchers at Karolinska Institutet show how a certain type of immune cells, macrophages, can be recruited into breast cancer tumors, where they are reprogrammed to support and drive tumor growth. In a study published in the scientific journal PNAS, they describe that low levels of the tumor suppressor protein TAp73 lead to hyperactivation of NFkB signaling and an inflammatory condition in breast cancer as well as secretion of molecules that recruit tumor-promoting macrophages into the tumor.
