衰老现象是生命的固有特征。因此,操纵它的可能性可能从远古时代就吸引了人类。最近的证据正在形成一种图景,即低热量的制度和运动可能会改善健康的衰老,并提出了几种药理学策略来对抗衰老。令人惊讶的是,迄今为止提出的最有效的干预措施只集中在少数细胞过程上,特别是营养信号传导,线粒体效率,蛋白质稳态和自噬。在这里,我们严格审查药物和行为,延长寿命或健康寿命的属性已被归因于和讨论潜在的分子机制。
The phenomenon of aging is an intrinsic feature of life. Accordingly, the possibility to manipulate it has fascinated humans likely since time immemorial. Recent evidence is shaping a picture where low caloric regimes and exercise may improve healthy senescence, and several pharmacological strategies have been suggested to counteract aging. Surprisingly, the most effective interventions proposed to date converge on only a few cellular processes, in particular nutrient signaling, mitochondrial efficiency, proteostasis, and autophagy. Here, we critically examine drugs and behaviors to which life- or healthspan-extending properties have been ascribed and discuss the underlying molecular mechanisms.
