Sci Rep:中国自闭症儿童的肠道菌群分析

2018-09-23 MedSci MedSci原创

自闭症谱系障碍(ASD)是一组复杂的神经发育障碍。最近的研究报道,与正常发育(TD)的儿童相比,ASD的儿童的肠道微生物群特征发生了改变。然而,在中国,很少有关于ASD儿童肠道细菌的研究。 在这里,为了阐明ASD患儿粪便微生物群的变化,研究人员进行16S rRNA测序,扩增16S rRNA(V3-V4)基因标签。我们调查了35名患有ASD的儿童和6名TD儿童的粪便微生物群的差异。 结果

自闭症谱系障碍(ASD)是一组复杂的神经发育障碍。最近的研究报道,与正常发育(TD)的儿童相比,ASD的儿童肠道微生物群特征发生了改变。然而,在中国,很少有关于ASD儿童肠道细菌的研究。

在这里,为了阐明ASD患儿粪便微生物群的变化,研究人员进行16S rRNA测序,扩增16S rRNA(V3-V4)基因标签。我们调查了35名患有ASD的儿童和6名TD儿童的粪便微生物群的差异。

结果系那是,在门水平,ASD组的粪便微生物群表明拟杆菌/厚壁菌比率显著增加。在属的水平上,与对照儿童相比,在ASD患儿Sutterella,Odoribacter和Butyricimonas的相对丰度中更高,而Veillonella和Streptococcus的丰度显著降低。功能分析表明,ASD组产丁酸盐和乳酸盐的菌较少。

此外,我们从人类微生物-疾病关系数据库下载了微生物疾病的关联数据集,并使用我们的肠道微生物组结果构建了包括ASD的人类疾病网络。在这种基于疾病微生物相似性的微生物疾病网络中,我们发现ASD与牙周疾病呈正相关,与1型糖尿病呈负相关。

因此,这些结果表明,基于微生物的疾病分析能够预测ASD与其他疾病之间的新型联系,并可能在揭示ASD的发病机制中发挥作用。
