科学期刊《自然》（Nature）刊登出一项新研究，美国加州大学洛杉矶分校（UCLA）的科学家原本想再生逐渐萎缩的胸腺，却意外发现衰老或许是可逆的。受试者在服药后不仅恢复免疫系统的活力，连表观“生物钟”（epigenetic clock）都平均逆转2.5年。

据《福斯新闻》报道，受试者服下包含一种生长激素及两种糖尿病药物的药品，主要用来测试生长激素能不能让胸腺组织再生，但该激素同时也会导致糖尿病，所以需要搭配糖尿病药物。

UCLA研究员霍瓦斯表示，原本预计生物钟可以放慢，但没想过还能达到逆转的程度，如今就像走进了未来世界。霍瓦斯用4种方法测量每位受试者的生物钟，结果都观察到明显的逆转。

但科学家也强调，这只是初步的研究结果，因为只有9名受试者，也没有任何对照组，如果将来能够再次证实，那对于医疗保健及高龄化社会可能有巨大的影响。
