ATP-binding cassette (ABC) transporters are the largest transporter families in human bodies; they are widely distributed and have complex functions. ABC transporters can mediate the translocation of various substrates on the cell membrane. This paper summarizes the structure, classification, function and action mechanism of ABC transporters and the research progress of ABC transporters in AD in recent years, and discusses the future research direction for preventing and treating AD in this field to provide new ideas and references for the prevention and treatment of AD.
