Expression of the TGF-β activating cell adhesion receptor αvβ6-integrin is closely related to cancer malignancy, since it drives invasion and metastasis. αvβ6-integrin is found in high density on tumor cells especially of pancreatic ductal adenocarcinoma (PDAC) [1], but also squamous cell-, cervical-, lung adeno-, and other carcinomas as well as fibrotic diseases (idiopathic pulmonary fibrosis, IPF). Sensitive probes for clinical imaging of αvβ6-integrin are thus highly desirable.
