Le conclusioni (per chi ha fretta[]):
What is the potential relevance of this study for human ageing? Clearly, if spermidine is found to increase life span or health span in rodents, it will join rapamycin and resveratrol as a leading candidate for treating age-associated
diseases in people. Of these, rapamycin is currently the only one known to enhancemouse longevity, but there are concerns that rapamycin may be of limited therapeutic value due to detrimental side effects such as immunosuppression13. No such side effects are known for spermidine. In addition, spermidine is a natural component of our diet, and several foods are known to be rich in spermidine, including soy beans, tea leaf, and mushrooms.
Evidence suggests that eating a diet rich in spermidine results in increased blood spermidine levels. Thus, it could be relatively easy for most people to obtain the benefits of spermidine through dietary modifications or by supplementation. However, there may be a darker side to spermidine with respect to mammalian ageing: oxidation of polyamines causes oxidative stress that can induce cell death, and high levels of polyamines are associated with malignancy. Indeed, chemical inhibitors of polyamine metabolism are being studied as potential anti-cancer agents.
