Efficient detection and removal of superfluous or damaged organelles are crucial to maintain cellular homeostasis and to assure cell survival. Growing evidence shows that organelles or parts of them can be removed by selective subtypes of otherwise unselective macroautophagy and microautophagy. This requires both the adaptation of the core autophagic machinery and sophisticated mechanisms to recognize organelles destined for turnover. We review the current knowledge on autophagic removal of peroxisomes, mitochondria, ER and parts of the nucleus with an emphasis on yeasts as a model eukaryote.
高效检测和清除多余或受损的细胞器对于维持细胞内稳态和确保细胞存活至关重要。越来越多的证据表明,细胞器或其部分可以通过原本非选择性的巨自噬和微自噬的选择性亚型被清除。这既需要核心自噬机制的适配,也需要复杂的机制来识别注定要被更新的细胞器。我们综述了目前关于过氧化物酶体、线粒体、内质网和部分细胞核自噬清除的知识,重点以酵母作为真核生物模型进行阐述。
