Recently, a team of scientists led by Duke University in Singapore successfully developed a drug called “Anti-IL-11”. This drug inhibits the inflammatory factor IL-11, which is closely related to accelerated aging. It not only significantly prolongs lifespan in mouse experiments, but also improves multiple health indicators, opening up a new path for human anti-aging treatment.

近日，新加坡杜克大学领导的科学家团队成功开发出一种名为「Anti-IL-11」的药物，该药物通过抑制与加速衰老密切相关的炎症因子IL-11，不仅在小鼠实验中显著延长了寿命，还改善了多项健康指标，为人类抗衰老治疗开辟了新路径。

Scientists have found in long-term research that key signaling mechanisms that regulate life span, such as ERK, STK11, AMPK, and the IGF1-insulin module, are disturbed during the aging process, leading to the appearance of aging signs such as decreased mitochondrial function, intensified inflammatory response, and cell aging. In particular, chronic sterile inflammation, as an important driver of the aging process, is closely lixed to the dysfunction of the immune system, among which the abnormal activation of cytokines such as IL-6 is particularly critical. The focus of this study, IL-11, is another important node in this complex network.

科学家们在长期的研究中发现，调控寿命的关键信号机制如ERK、STK11、AMPK及IGF1-胰岛素模块等在衰老过程中受到干扰，导致线粒体功能下降、炎症反应加剧及细胞老化等衰老标志的出现。 特别是慢性无菌性炎症，作为衰老进程中的重要推手，与免疫系统的功能失调紧密相连，其中IL-6等细胞因子的异常激活尤为关键。 而此次研究的焦点——IL-11，则是这一复杂网络中的又一重要节点。

Studies have shown that the inflammatory factor IL-11 is upregulated in mice with age, and has a profound impact on the aging process of cells, tissues and even the entire body by regulating the ERK-AMPK-mTORC1 signaling pathway. This finding has not only been verified in animal models, but similar IL-11 expression upregulation has also been observed in the elderly population , further highlighting the great potential of IL-11 as an anti-aging therapeutic target.

研究表明，IL-11这一炎症因子在小鼠体内随年龄增长而上调，并通过调控ERK-AMPK-mTORC1信号通路，对细胞、组织乃至整个机体的衰老过程产生深远影响。 该发现不仅在动物模型中得到了验证，还在老年人群体中观察到了相似的IL-11表达上调现象，这进一步凸显了IL-11作为抗衰老治疗靶点的巨大潜力。

The research team implemented anti-IL-11 antibody treatment in mice and found that after 25 weeks of treatment, the metabolism and muscle function of mice, which are equivalent to 55 years old in humans, were significantly improved, aging biomarkers were significantly reduced, and physical weakness was effectively alleviated. Among them, the lifespan of male mice was extended by 22.4%, female mice by 25%, and an average of 24.9%, providing the possibility of anti-aging treatment for humans.

研究团队在小鼠中实施了Anti-IL-11抗体治疗，结果发现，在相当于人类55岁高龄的老年小鼠中，经过25周的治疗，这些小鼠的新陈代谢、肌肉功能均得到了显著改善，衰老生物标志物显著减少，身体虚弱状况得到有效缓解。 其中，雄性小鼠的寿命延长了22.4%，雌性延长了25%，平均延长了24.9%，为人类抗衰老治疗提供了可能性。

Scientists said that the current research results are mainly based on mouse models, and their effects in humans need to be verified through more in-depth clinical studies. However, this breakthrough has undoubtedly brought unprecedented hope to the field of anti-aging science, giving us reason to believe that in the near future, humans may be able to effectively delay aging and improve the quality of life through scientific means, taking a big step towards the dream of immortality.

科学家表示，当前的研究成果主要基于小鼠模型，其在人类中的效果尚需通过更多深入的临床研究来验证。 不过，该突破无疑为抗衰老科学领域带来了前所未有的希望，让我们有理由相信，在不久的将来，人类或许能够通过科学的手段，有效延缓衰老，提升生命质量，向着长生不老的梦想迈进一大步。

This research breakthrough from Duke University Singapore shows that biological agents targeting specific inflammatory factors have great potential in delaying aging and improving the quality of life. As the trend of population aging intensifies, the market demand for anti-aging treatments is gradually increasing. This research result provides new development directions and opportunities for the biological agent industry.
