摘要:

分子伴侣介导的自噬是3种自噬中的之一,其特征是选择性降解蛋白质。分子伴侣介导的自噬有助于维持能量平衡及细胞内稳态,同时也能为细胞生存提供营养和支持。包括神经元在内几乎所有细胞中都可以检测到分子伴侣介导的自噬。由于神经元对环境变化极其敏感,因此维持神经元稳态对神经元的生长和存活至关重要。既往研究已证明,神经元损伤和细胞死亡通常伴随着分子伴侣介导的自噬的功能障碍。此外,分子伴侣介导的自噬功能障碍与中枢神经系统疾病也密切相关。在某些情况下,调节分子伴侣介导的自噬活性会减弱神经毒性。因此,此次综述回顾了分子伴侣介导的自噬在神经退行性疾病、脑损伤、神经胶质瘤和自身免疫性疾病中的变化,并总结了分子伴侣介导的自噬调控的最新研究进展,最后讨论了分子伴侣介导的自噬作为中枢神经系统疾病治疗靶点的潜力。

Abstract: Chaperone-mediated autophagy is one of three types of autophagy and is characterized by the selective degradation of proteins. Chaperone-mediated autophagy contributes to energy balance and helps maintain cellular homeostasis, while providing nutrients and support for cell survival. Chaperone-mediated autophagy activity can be detected in almost all cells, including neurons. Owing to the extreme sensitivity of neurons to their environmental changes, maintaining neuronal homeostasis is critical for neuronal growth and survival. Chaperone-mediated autophagy dysfunction is closely related to central nervous system diseases. It has been shown that neuronal damage and cell death are accompanied by chaperone-mediated autophagy dysfunction. Under certain conditions, regulation of chaperone-mediated autophagy activity attenuates neurotoxicity. In this paper, we review the changes in chaperone-mediated autophagy in neurodegenerative diseases, brain injury, glioma, and autoimmune diseases. We also summarize the most recent research progress on chaperone-mediated autophagy regulation and discuss the potential of chaperone-mediated autophagy as a therapeutic target for central nervous system diseases.
