饮食限制通过自噬激活促进了几个物种的长寿。然而,这种效应背后的溶酶体的变化仍然不清楚。在这里,我们使用线虫秀丽线虫,我们证明了自噬管状溶酶体(TLS)的诱导,发生在饮食限制或雷帕霉素抑制的机械靶标时,是一个将减少食物摄入量与延长寿命联系起来的关键事件。我们发现,饥饿不仅在受影响的个体中诱导TL,而且在喂养良好的后代中也诱导TL,并且在喂养良好的后代中肠道TL的存在预示着寿命的延长。此外,我们证明了果蝇小VCP相互作用蛋白的表达,一种果蝇的TL激活剂,人工诱导喂养良好的蠕虫的TL,并改善线虫在老年的健康。这些发现将TL确定为一种新的溶酶体,将饥饿与健康衰老联系在一起。作者报告说,溶酶体形态的变化,从囊状到管状,支持在饮食限制时延长寿命,并在人工刺激时促进自噬增强和健康衰老。
Dietary restriction promotes longevity in several species via autophagy activation. However, changes to lysosomes underlying this effect remain unclear. Here using the nematode Caenorhabditis elegans, we show that the induction of autophagic tubular lysosomes (TLs), which occurs upon dietary restriction or mechanistic target of rapamycin inhibition, is a critical event linking reduced food intake to lifespan extension. We find that starvation induces TLs not only in affected individuals but also in well-fed descendants, and the presence of gut TLs in well-fed progeny is predictive of enhanced lifespan. Furthermore, we demonstrate that expression of Drosophila small VCP-interacting protein, a TL activator in flies, artificially induces TLs in well-fed worms and improves C. elegans health in old age. These findings identify TLs as a new class of lysosomes that couples starvation to healthy aging. The authors report that a change to lysosome morphology, from vesicular to tubular form, supports lifespan extension upon dietary restriction and promotes heightened autophagy and healthy aging when stimulated artificially in well-fed animals.
