Abstract

Reciprocal interactions between tumor cells and their microenvironment drive cancer progression and therapy resistance. In this issue, Nabet et al. demonstrate that dynamic feedback between tumor and stroma subverts normal inflammatory responses by triggering the release of exosomes containing unshielded RNAs that activate pattern recognition receptors, thereby promoting tumor growth and metastasis.
