Functional expression of the interleukin-11 receptor alpha-chain in normal colonic epithelium and colon cancer

AbstractBackground  Interleukin-11 (IL-11) has been evaluated as an anti-inflammatory and mucosa-protective therapeutic agent in inflammatory bowel diseases (IBDs). Activity of IL-11 requires binding to the α receptor subunit (IL-11Rα) that provides ligand specificity. Recently, we showed that in the intestinal mucosa, IL-11Rα is mainly present on epithelial cells mediating antiapoptotic effects. The aim of this study was to investigate the expression profiling of IL-11Rα and its downstream signaling cascade in colonic adenoma and carcinoma.
