Abstract

Outer membrane vesicles (OMVs) play vital roles in bacterial communication both intraspecifically and interspecifically. However, extracellular mechanisms of gut microbiota–derived OMVs in the intestine remain poorly understood. Here, we report that OMVs released from Akkermansia muciniphila are able to (i) restore disturbed balance of the gut microbiota by selectively promoting the proliferation of beneficial bacteria through membrane fusion, (ii) elicit mucosal immunoglobulin A response by translocating into Peyer’s patches and subsequently activating B cells and dendritic cells, and (iii) maintain the integrity of the intestinal barrier by entering intestinal epithelial cells to stimulate the expressions of tight junctions and mucus. We demonstrate that transplantation of gut microbiota–associated OMVs to the intestine can alleviate colitis and enhance anti–programmed cell death protein 1 therapy against colorectal cancer by regulating intestinal homeostasis. This work discloses the importance of gut microbiota–derived OMVs in intestinal ecology, providing an alternative target for disease intervention and treatment.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
