Autophagy is a fundamental catabolic process whereby excessive or damaged cytoplasmic components are degraded through lysosomes to maintain cellular homeostasis. Studies of mTOR signaling have revealed that mTOR controls biomass generation and metabolism by modulating key cellular processes, including protein synthesis and autophagy. Primary cilia, the assembly of which depends on kinesin molecular motors, serve as sensory organelles and signaling platforms. Given these pathways' central role in maintaining cellular and physiological homeostasis, a connection between mTOR and primary cilia signaling is starting to emerge in a variety of diseases. In this review, we highlight recent advances in our understanding of the complex crosstalk between the mTOR pathway and cilia and discuss its function in the context of related diseases.
自噬是一种基本的分解代谢过程,通过溶酶体降解过量或受损的细胞质成分,以维持细胞内的平衡。mTOR 信号通路的研究表明,mTOR 通过调节包括蛋白质合成和自噬在内的关键细胞过程来控制生物量的产生和代谢。初级纤毛作为感觉细胞器和信号平台,其组装依赖于驱动蛋白分子马达。鉴于这些途径在维持细胞和生理平衡方面的核心作用,mTOR 和初级纤毛信号之间的联系开始在各种疾病中显现出来。在这篇综述中,我们强调了对 mTOR 途径和纤毛之间复杂串扰的理解的最新进展,并讨论了其在相关疾病中的功能。
