亚精胺是一种天然多胺,可刺激细胞保护性巨噬/自噬。外部补充亚精胺可以延长物种的寿命和健康跨度,包括酵母、线虫、苍蝇和小鼠。在人类中,亚精胺水平随着年龄的增长而下降,并且已经提出内源性亚精胺浓度降低与年龄相关的退化之间可能存在联系。最近的流行病学数据支持这一观点,表明在富含亚精胺的食物中增加这种多胺的摄入可以降低与心血管疾病和癌症相关的总体死亡率。在这里,我们讨论营养和其他可能的途径来抵消年龄介导的亚精胺水平下降。
Spermidine is a natural polyamine that stimulates cytoprotective macroautophagy/autophagy. External supplementation of spermidine extends lifespan and health span across species, including in yeast, nematodes, flies and mice. In humans, spermidine levels decline with aging, and a possible connection between reduced endogenous spermidine concentrations and age-related deterioration has been suggested. Recent epidemiological data support this notion, showing that an increased uptake of this polyamine with spermidine-rich food diminishes overall mortality associated with cardiovascular diseases and cancer. Here, we discuss nutritional and other possible routes to counteract the age-mediated decline of spermidine levels.
