Identification of MFG-E8 as a novel therapeutic target for diseases

Introduction: Milk fat globule-epidermal growth factor-factor 8 (MFG-E8), a peripheral membrane glycoprotein has been widely studied in recent years due to its omnipresent locations, express and multiple functions. Traditionally, MFG-E8 was identified as an outstanding factor for phagocytosis of apoptotic cells and a significant factor in immune systems. Recent studies with some new findings have shed an interesting light on the old peripheral membrane glycoprotein in various diseases. Areas covered: In inflammatory and the systemic lupus erythematosus-type autoimmune disease, age-related diseases and tumors, MFG-E8 plays a multifunctional role in attenuating inflammation and improving prognosis, healing wound and remodeling arterial and enhancing tumorigenicity and cancer metastasis. This review provides a comprehensive view on the latest advances in the field. The summarized knowledge will help to explore the potential therapeutic roles of MFG-E8 and to design MFG-E8-based strategies for the treatment o...
