WebGuanylate cyclase C (GUCY2C) is a transmembrane receptor expressed on the luminal aspect of the intestinal epithelium. Its ligands include bacterial heat-stable enterotoxins responsible for traveler's diarrhea, the endogenous peptide hormones uroguanylin and guanylin, and the synthetic agents, linaclotide, plecanatide, and dolcanatide. WebMay 8, 2024 · Dr Snook created a CAR-T therapy made specifically to treat GUCY2C-expressing cancers such as colorectal cancer.
