Abstract:
BACKGROUND: Tendon is a fibrous tissue that connects bone and muscle. The main function is to conduct stress from the muscles to the bone during exercise. Tendinopathy is a commonly seen disease, characterized by tendon inflammation, degeneration and injury. Autophagy is widely involved in the development of many degenerative diseases. The research method based on autophagy provides a new idea for tendon repair. OBJECTIVE: To review the process and regulation mechanism of autophagy, and to analyze the pathological mechanism of autophagy involved in the tendinopathy so as to provide a reference for the prevention and treatment of tendinopathy. METHODS: The articles concerning autophagy and tendinopathy were retrieved by computer in CNKI, WanFang and PubMed databases. The keywords were "autophagy, tendon, fibroblast, tendinopathy" in English and Chinese, respectively. Finally, 54 articles were obtained through systematic induction and analysis after excluding the irrelevant and repetitive articles. RESULTS AND CONCLUSION: Autophagy can alleviate the damage to human tendon stem cells induced by oxidative stress. With the increase of the degree of extracellular matrix degradation in the tendon tissue, autophagic cell death occurs in the tendon cells due to excessive autophagy. Prostaglandin E2 significantly induces fibroblast death and autophagy in a dose-dependent manner. The muscle atrophy after the rotator cuff injury is regulated by autophagy. Rapamycin prevents peritendinous fibrosis through activation of autophagy. In conclusion, autophagy plays an important role in tendinopathy. Autophagy will become a new hotspot in tendinopathy. Further understanding of autophagy and its role in tendinopathy will contribute to finding a targeted autophagy pathway and provide new theoretical and methodological support for the intervention and treatment of tendinopathy.
