Exocrine Gland Morphogenesis: Insights into the Role of Amphiregulin from Development to Disease

AbstractAmphiregulin (AREG) is a well-characterized member of the epidermal growth factor (EGF) family and is one of the ligands of the EGF receptor (EGFR). AREG plays a key role in mammalian development and in the control of branching morphogenesis in various organs. Furthermore, AREG participates in a wide range of physiological and pathological processes activating the major intracellular signalling cascades governing cell survival, proliferation and motility. In this article, we review current advances in exocrine glands morphogenesis, focusing on the salivary gland, and discuss the essential aspects of AREG structure, function and regulation, and its differential role within the EGFR family of ligands. Finally, we identify emerging aspects in AREG research applied to mammary gland development and the salivary gland autoimmune disease, Sj ögren’s syndrome.
