CELL:益生菌补充剂或对人体无效

经验益生菌通常被健康个体消费,作为改善生活质量和预防疾病的手段。然而,关于益生菌肠粘膜定植功效的证据仍然稀少和有争议。

经验益生菌通常被健康个体消费,作为改善生活质量和预防疾病的手段。然而,关于益生菌肠粘膜定植功效的证据仍然稀少和有争议。
最近,来自魏茨曼科学研究所的研究人员在宏观上对小鼠和人类粘膜相关的肠道微生物组进行了表征,发现其只与粪便微生物组成部分相关。
在基线,和11种益生菌组合或安慰剂的消费期间,研究人员进行连续侵入性多组学测量,发现益生菌在通过肠道时仍然存活。
在定殖的但不是无菌的小鼠中,益生菌遇到显着的粘膜定植抗性。相比之下,人类的特征是人,区域和菌株特异性粘膜定植模式,由预测基线宿主和微生物组特征标记,但在粪便中存在的益生菌无法区分。
因此,益生菌诱导对粘膜群落结构和肠道转录组的短暂,个体化影响。
总的来说,经验性益生菌补充剂可能在普遍和持续影响肠粘膜方面受到限制,值得开发新的个性化益生菌方法。

CELL:益生菌真的有益肠道健康吗?

在我们的皮肤表面、胃肠道、口腔、呼吸道、泌尿生殖道、粪便等部位分布着大量的细菌,尤其胃肠道细菌的种类最为繁多、数目最为巨大,占人体微生物总量的约80%。健康成人肠道内的菌有1000多种,数量高达一百万亿,是我们人体表细胞总数的10倍;人体胃肠道共有超过1014个细菌,每克干粪中就有4000亿个共生菌。所以说,你并不是独立的生物,而是和菌群相互依赖、共生的共同体。
