溶酶体长期以来被视为细胞的“垃圾桶”。然而,最近的发现已经挑战了这种简单的观点,并建立了溶酶体在营养依赖性信号转导中的核心作用。溶酶体的降解作用与其新发现的信号传导功能并不冲突,相反,它们广泛合作以介导基本的细胞活动,如营养感测、代谢适应以及蛋白质和细胞器的质量控制。此外,基于溶酶体的信号传导和降解受到相互调节。越来越复杂的转录程序控制着溶酶体的生物发生、组成和丰度,并微调它们的活性以匹配细胞不断变化的需求。这些基本活性的改变对于不断扩大的病症谱(包括胆积障碍、神经退行性疾病和癌症)的病理生理学至关重要,这并不令人惊讶。因此,解开这个迷人的细胞器的功能将有助于我们理解代谢组织的基本逻辑,并指出几种人类疾病的新治疗途径。
The lysosome has long been viewed as the ‘trash can’ of the cell. However recent discoveries have challenged this simple view and established a central role of the lysosome in nutrient dependent signal transduction. The degradative role of the lysosome and its newly discovered signaling function are not in conflict, rather they cooperate extensively to mediate fundamental cellular activities such as nutrient sensing, metabolic adaptation and quality control of proteins and organelles. Moreover, lysosome-based signaling and degradation are subject to reciprocal regulation. Transcriptional programs of increasing complexity control the biogenesis, composition and abundance of lysosomes, and fine-tune their activity to match the evolving needs of the cell. Alterations in these essential activities are, not surprisingly, central to the pathophysiology of an ever-expanding spectrum of conditions including storage disorders, neurodegenerative diseases and cancer. Thus unraveling the functions of this fascinating organelle will contribute to our understanding of the fundamental logic of metabolic organization and point to novel therapeutic avenues in several human diseases.
