NLRP3 inflammasome in fibroblasts links tissue damage with inflammation in breast cancer progression and metastasis

Abstract

Cancer associated fibroblasts (CAFs) are known to promote pro-tumorigenic inflammation. Here, the authors show that CAFs sense tissue damage and activate NLRP3 inflammasome and pro-inflammatory IL-1β secretion, and CAF-derived inflammasome signalling promotes breast tumour growth and metastasis.
