「菌-腸-腦」軸線:從胃腸蠕動到情緒

摘要


「菌-腸-腦」軸線(microbiota-gut-brain axis)在維持體內平衡(homeostasis)中扮演重要腳色。身體內有許多內在和外在因素,包含中樞神經系統,外在生活壓力,飲食習慣等等均可能會影響「菌-腸-腦」軸線,影響大腦內各種分子及神經傳導物質功能,進而調控腸道和中樞神經系統兩者的功能。最近許多研究發現腸道微生物可以作為調節腸腦信號傳導的重要因子。本篇文章將會描述「菌-腸-腦」軸線,在調節腸道和中樞神經系統的角色,以及「菌-腸-腦」軸線如何影響腸躁症(irritable bowel syndrome)和有關情緒和情感精神障礙的疾病。
