在老龄化研究中存在一种现象,即早期生活压力对寿命有积极影响。这些观察结果背后的机制表明,细胞防御机制具有强大的、持久的诱导作用。这些包括内质网、细胞质和线粒体的各种未折叠蛋白反应。事实上,在没有压力的情况下,这些通路的异位诱导足以延长酵母菌、蠕虫和苍蝇等多种生物的寿命。在这里,我们概述了在细胞质、线粒体和内质网中运作的蛋白质质量控制机制,并讨论了它们在应激和衰老过程中如何影响细胞健康和活力。
There exists a phenomenon in aging research whereby early life stress can have positive impacts on longevity. The mechanisms underlying these observations suggest a robust, long-lasting induction of cellular defense mechanisms. These include the various unfolded protein responses of the ER, cytosol, and mitochondria. Indeed, ectopic induction of these pathways, in the absence of stress, is sufficient to increase lifespan in organisms as diverse as yeast, worms, and flies. Here, we provide an overview of the protein quality control mechanisms that operate in the cytosol, mitochondria, and ER, and discuss how they impact cellular health and viability during stress and aging.
