适量饮咖啡或可减缓精神疾病患者细胞老化过程
Ke Ji Ri Bao· 2025-11-27 00:05
据最新一期《BMJ精神卫生》杂志报道,英国伦敦国王学院领导的国际团队的一项新研究显示,每天饮 用不超过3至4杯咖啡,可能有助于减缓重度精神疾病患者的细胞老化过程。 细胞端粒会随年龄自然缩短,在精神分裂症、双相情感障碍等重度精神疾病患者中,这一缩短过程往往 更加明显。 为了解咖啡摄入是否影响端粒长度,研究团队分析了挪威"主题组织性精神病研究"中436名成年参与者 的数据。结果显示,每天饮用3至4杯咖啡者的端粒长度明显长于不喝咖啡的参与者,但每天饮用5杯以 上者则未体现类似趋势。这一差异在调整吸烟、年龄、性别、药物治疗等因素后仍然存在。 值得注意的是,研究所指的"3至4杯"沿用了流行病学常用换算,即每杯约含80—100毫克咖啡因。现代 商业咖啡店的饮品容量更大、咖啡因含量也更高。因此,对于喝速溶或自家小杯手冲的人来说,"每天3 —4杯"较为合适。但若饮用的是大杯商业美式,1—2杯就可能接近研究中的最佳摄入量。 研究团队强调,本研究为观察性研究,无法证明咖啡本身使端粒变长,且未记录咖啡类型、饮用时间与 其他含咖啡因饮料等可能干扰因素。 (文章来源:科技日报) ...

团队表示,除多通路协同抗癌,该平台还突破了当前细胞疗法在时间、工艺与成本方面的限制。现有疗 法需采集患者自身细胞,送往专门设施进行数周改造,再回输体内,而自然杀伤T细胞与人体免疫系统 天然兼容,不会引发严重排斥反应,因此可利用捐献的血液干细胞实现规模化生产。 为突破这些障碍,研究团队调用了自然杀伤T细胞。通过为其配备靶向胰腺癌细胞蛋白"间皮素"的嵌合 抗原受体,这些细胞能同时启动多种攻击机制,对肿瘤展开全方位围剿。 在针对胰腺原位肿瘤及肝转移瘤(最常见且致命的转移类型)的严苛动物模型中,CAR-NKT细胞展现 出强大的肿瘤清除能力。即便在高度炎性的肿瘤微环境中,治疗细胞仍保持抗癌活性,且不易出现衰 竭。 美国加州大学洛杉矶分校科研团队开发出一种新型嵌合抗原受体-自然杀伤T细胞(CAR-NKT)免疫疗 法。即便癌细胞已转移至其他器官,该疗法也能精准识别并摧毁胰腺癌细胞。相关论文发表于新一期 《美国国家科学院院刊》。 此前,嵌合抗原受体-T(CAR-T)细胞疗法虽在部分血癌治疗中取得突破,却难以应对胰腺癌等实体 瘤。胰腺肿瘤外围包裹着致密的结缔组织与抑制性免疫细胞,形成一道天然屏障,阻碍治疗细胞进入。 更棘手的是 ...
