CELL:膳食纤维经肠道细菌加工后影响多发性硬化病程

2020-03-16 MedSci原创 MedSci原创

服用PA 3年后,MS年复发率降低,疾病相关的残疾情况稳定,脑萎缩减少。功能微生物组分析显示,PA摄入后肠中Treg细胞诱导基因表达增加。

短链脂肪酸是难以消化的膳食纤维经肠道细菌加工而成的,具有免疫调节作用。

最近,研究人员研究丙酸(PA)在多发性硬化(MS)症,一种自身免疫性和神经退行性疾病,中的作用。

研究人员发现,与对照组相比,多发性硬化症患者的血清和粪便中PA含量明显降低,尤其是在首次复发后。

在一项概念验证研究中,研究人员将PA补充到未经治疗的MS患者中,并作为MS免疫治疗的补充。PA摄入2周后,研究人员观察到功能正常的调节性T细胞(Treg)明显持续增加,而Th1和Th17细胞明显减少。

事后分析显示,服用PA 3年后,MS年复发率降低,疾病相关的残疾情况稳定,脑萎缩减少。功能微生物组分析显示,PA摄入后肠中Treg细胞诱导基因表达增加。

此外,在MS中,PA使Treg细胞的线粒体功能和形态正常化。

因此,该研究结果表明,PA可以作为MS药物的一种有效的免疫调节补充。
