Based on the aforementioned results, we aimed to provide novel mechanistic insights into the paracrine action of IL11 on main components of the BC microenvironment such as CAFs, which express the IL11 receptor, IL11Rα (Interleukin‐11 receptor alpha), and the glycoprotein 130 (gp130) co‐receptor (data not shown). Here, IL11 is linked to breast cancer.
