Nature Immunology杂志最近发表的一项研究表明,阑尾在一类免疫细胞的帮助下对消化系统健康起到了关键作用。阑尾并不是多余的退化器官,而是默默做出贡献的无名英雄。

Gabrielle Belz教授和Eric Vivier教授领导的研究团队发现,对于免疫系统存在缺陷的人来说先天淋巴细胞(ILC)是非常重要的。这些细胞保护阑尾避免细菌感染,帮助阑尾成为好细菌的天然“水库”,对机体健康产生重要影响。

阑尾应当受到更多地重视,“人们普遍将阑尾视为我们人体的负累,”Belz教授指出。“切除阑尾是最常见的手术之一。现在我们需要重新思考阑尾的地位,正确认识它与人体健康之间的关系。”

“微生物组平衡是肠道从细菌威胁(比如食物中毒)中恢复健康的关键。我们的研究显示,阑尾有助于微生物组中有益细菌的重新生长。”

“在某些情况下,医生需要通过粪便移植在患者肠道内重新种植健康细菌,比如把健康人的肠道菌移植给患者,”Belz教授说。如果你有一个健康的阑尾,可能就不需要进行这样的治疗。

“ILC在维持阑尾完整性方面起到了重要的作用,”Belz教授解释道。“健康人体内的免疫大军部下了多层次的免疫防线,当一层防线被破坏的时候,还有后备军可以对抗感染。”

“这些细胞对免疫系统存在缺陷的人(比如正在接受治疗的癌症患者)非常关键,它们负责在消化系统中对抗细菌感染。当其他免疫细胞被消灭的时候,肠道ILC却能存活下来,起到不容忽视的保护作用。”

Belz教授之前的工作显示,特定膳食(比如绿色多叶植物的蛋白)可以促进ILC的生产。“ILC也在过敏性疾病(比如哮喘)、炎症性肠病和银屑病中起作用。进一步研究这些细胞在肠道中的作用机制,并在此基础上治疗疾病是非常有意义的。”

空气污染侵害肺和阑尾

Nat Commun:阑尾是益生菌的“庇护所”

阑尾无用论较为流行,而日本研究人员在英国《自然-通讯》杂志网络版上报告说,动物实验显示,阑尾能向肠道提供免疫细胞,发挥了保持肠内细菌平衡的作用。阑尾在腹部的右下方,位于盲肠与回肠之间,是细长而弯曲的盲管,远端闭锁。由于阑尾被认为没什么作用,而且有时会发炎,因此有时在其他手术时被顺带切除。研究人员对比研究了切除阑尾的实验鼠和没有切除阑尾的实验鼠,发现切除阑尾的实验鼠大肠内一种免疫细胞减少了一半,肠内
