自噬是一种从酵母到哺乳动物都存在的大量细胞质降解过程。自噬是细胞对饥饿和应激的一种重要反应,在发育、细胞死亡、衰老、免疫和癌症中起着重要作用。果蝇Drosophila melanogaster为研究发育中生物体的体内自噬提供了一个很好的模型系统。自噬(atg)基因及其调控因子在果蝇中是保守的,自噬是在发育过程中对营养饥饿和激素的反应中诱导的。在这篇综述中,我们提供了一个概述,果蝇的研究如何有助于我们了解的作用和调节细胞的生存,生长,营养利用和细胞死亡的自噬。最近的果蝇研究也提供了关于自噬在蛋白质聚集障碍、神经变性、衰老和先天免疫中的作用的重要机制信息。自噬在特定环境和/或细胞类型中的作用差异表明,可能存在细胞环境特异性的自噬调节因子,而果蝇的研究非常适合于发现这种特异性。
Macroautophagy (autophagy) is a bulk cytoplasmic degradation process that is conserved from yeast to mammals. Autophagy is an important cellular response to starvation and stress, and plays important roles in development, cell death, aging, immunity, and cancer. The fruit fly Drosophila melanogaster provides an excellent model system to study autophagy in vivo, in the context of a developing organism. Autophagy (atg) genes and their regulators are conserved in Drosophila, and autophagy is induced in response to nutrient starvation and hormones during development. In this review we provide an overview of how Drosophila research has contributed to our understanding of the role and regulation of autophagy in cell survival, growth, nutrient utilization, and cell death. Recent Drosophila research has also provided important mechanistic information about the role of autophagy in protein aggregation disorders, neurodegeneration, aging, and innate immunity. Differences in the role of autophagy in specific contexts and/or cell types suggest that there may be cell-context-specific regulators of autophagy, and studies in Drosophila are well-suited to yield discoveries about this specificity.
