In this paper, the authors showed for the first time that pancreatic adenocarcinoma cells secrete BAG3 that acts as a cytokine activating a paracrine loop. Indeed we show that BAG3 binds to macrophages through a membrane protein that acts as receptor, IFITM-2, and activates PI3K and the p38 MAPK signaling pathways leading to the release of a number of factors, including IL6 from macrophages that in turn stimulate tumor growth.
