结肠粘液将肠道微生物群从宿主组织中分离出来,但它如何在整个结肠中组织起作用尚不清楚。在这里,我们发现结肠粘液由Muc2的两种不同的o -糖基化实体组成:一种主要形式由近端结肠产生,它包裹着包括微生物群在内的粪便物质,另一种次要形式来自远端结肠,它附着在主要形式上。微生物群通过诱导近端结肠杯状细胞产生Muc2来指导其包封。反过来,近端衍生Muc2上的o -聚糖调节微生物群的结构和功能以及结肠粘膜的转录组。这些研究表明,近端结肠通过产生o糖基化粘液,作为宿主-微生物共生的主要调节剂。富含o -甘聚糖的粘液包裹着结肠微生物群
Colon mucus segregates intestinal microbiota from host tissues, but how it organizes to function throughout the colon is unclear. Here we reveal that colon mucus consists of two distinct O-glycosylated entities of Muc2: a major form produced by the proximal colon, which encapsulates the fecal material including the microbiota, and a minor form derived from the distal colon, which adheres to the major form. The microbiota directs its encapsulation by inducing Muc2 production from proximal colon goblet cells. In turn, O-glycans on proximal-derived Muc2 modulate the structure and function of the microbiota as well as the transcriptome of the colon mucosa. These studies demonstrate that the proximal colon, by producing O-glycosylated mucus, acts as a master regulator of host-microbe symbiosis. O-glycan-rich mucus encapsulates colon microbiota
