Abstract (original English)

Alzheimer's disease (AD) is a common form of dementia characterized by memory loss, cognitive and linguistic abilities declining and self-care capabilities diminishment. With the aging population globally, AD poses a significant threat to public health. Current treatments for AD aim to alleviate symptoms and slow down disease progression, but due to the limited understanding of underlying disease mechanisms, AD is still impossible to be cured yet. In recent years, there has been an exponential growth in exosome-related research because of their excellent biocompatibility ability, loading capacity and cellular internalization, making exosome to be one of the hotspots and a promising strategy in AD therapy research. This comprehensive review systematically explores the potential roles of various exosome-based nanotherapeutic strategy in AD treatment, with a particular focus on their specific biological mechanisms of action. Firstly, we elaborated on the pathological mechanisms of AD formation as well as the mechanisms related to the formation, secretion and function of exosome. Additionally, we highlighted the research progress in the development of exosome-based nanotherapeutic strategies for AD treatment and their corresponding biological mechanisms. Furthermore, we delved into the challenges and opportunities these strategies facing in clinical application. Looking forward to
