Although the cloning and molecular characterization of MFG-E8 was first reported in the early 90s, breakthrough on MFG-E8 research came into light when it was explored as an outstanding factor for phagocytosis of apoptotic cells by professional macrophages in 2002. Since then numerous studies have been performed on MFG-E8 not only to demonstrate the role of phagocytic clearance of apoptotic cells, but also to focus on a wide range of aspects, even emphasizing on a direct link to innate-immune systems. In terms of its role as therapeutic potentials, our group, as well as others, has shown MFG-E8 to be an essential factor in attenuating inflammation and improving prognosis in several animal models of life threatening diseases. Considering these versatile functions of MFG-E8, several in vitro and in vivo studies were embarked on to explore the mechanistic pathways exerted by MFG-E8 during inflammation. With the relevant cumulative findings, herein we reviewed the potential roles of MFG-E8 in pathophysiological conditions by highlighting its plausible signal-transduction mechanisms.
