热量限制(CR)没有营养不良的情况下,在不同物种中延缓衰老并延长寿命;然而,其对灵长类动物疾病抵抗力和死亡率的影响尚不清楚。我们报告了一项为期20年的恒河猴成年期CR纵向研究的结果,旨在填补衰老研究中的这一关键空白。在威斯康星州国家灵长类动物研究中心的猕猴种群中,中度CR降低了衰老相关死亡的发生率。在报告的时间点,50%的对照喂养动物存活,而CR动物的存活率为80%。此外,CR延迟了年龄相关病理的发作。具体来说,CR降低了糖尿病、癌症、心血管疾病和脑萎缩的发病率。这些数据表明,CR减缓了灵长类物种的衰老。
Caloric restriction (CR) without malnutrition delays aging and extends lifespan in diverse species; however, its effect on resistance to illness and mortality in primates is not clearly established. We report findings of a 20-year longitudinal adult-onset CR study in rhesus monkeys aimed at filling this critical gap in aging research. In a population of rhesus macaques maintained at the Wisconsin National Primate Research Center, moderate CR lowered the incidence of aging-related deaths. At the time point reported 50% of control fed animals survived compared with 80% survival of CR animals. Further, CR delayed the onset of age-associated pathologies. Specifically, CR reduced the incidence of diabetes, cancer, cardiovascular disease, and brain atrophy. These data demonstrate that CR slows aging in a primate species.
