当代人类的平均寿命约为 71 岁，有少数人能迎来百岁生日，而能活过 110 岁的人则更稀有，他们被称为“超级百岁老人”。根据发表在《Cell Reports》期刊上的一项研究，日本大阪大学研究团队发现，一种罕见的免疫细胞会随着极端高龄而显著增加。这类细胞兼具识别威胁和杀伤危险细胞的能力，或有助于超级百岁老人应对随着年龄增长而增加的持续性健康威胁。随着年龄增长，一些疾病的患病风险会增加，人体抵御感染的免疫能力也会逐渐减弱。T细胞是人体免疫系统的一类重要细胞，主要分为两类：辅助性T细胞负责协调免疫反应，杀伤性T细胞则负责清除受感染或癌变细胞。研究人员发现，超级百岁老人会积累一种不同寻常的“混合型”T细胞，即CD4细胞毒性T淋巴细胞（CD4 CTL）。这类罕见细胞同时具备识别威胁和摧毁危险细胞的能力。研究人员分析了不同年龄组人群的免疫细胞，包括70—90岁人群、百岁老人以及超级百岁老人。结果发现，在生命的大部分阶段，这类细胞始终十分少见，但在接近100岁时开始显著增加。在超级百岁老人中，CD4 CTL占血液中全部T细胞的比例接近1/5，而在较年轻的研究参与者中，这一比例仅约4%。进一步分析发现，部分CD4 CTL发生了明显的克隆扩增，即少数细胞不断复制，形成了数量庞大的同源细胞群。这一现象提示，这些细胞可能长期受到某些特定抗原的反复刺激，并在持续的免疫应答过程中不断增殖。研究人员还发现，超级百岁老人这类细胞所携带的部分T细胞受体，与癌症患者肿瘤组织中的T细胞受体高度相似，但这些超级百岁老人均无癌症病史。研究人员表示，这一发现提示，这些免疫细胞可能具有识别肿瘤细胞的能力，甚至可能在肿瘤尚未发展到临床可检测阶段时，就已对其产生免疫反应。这些发现意味着，极端高龄时期的免疫变化可能并非免疫系统单纯“衰老”和“耗竭”，而更像是免疫系统为适应长期健康生存而进行的一种重新组织。
