Akkermansia muciniphila outer membrane protein Amuc_0904 promotes goblet cell differentiation

ABSTRACT: Akkermansia muciniphila is recognized as a promising probiotic that improves the symptoms of a variety of diseases. However, the role and mechanism of A. muciniphila in regulating intestinal homeostasis remain to be explored. Here, we discovered that A. muciniphila was dramatically increased during colitis recovery, and its colonization greatly increased goblet cells to protect the intestinal barrier in mice. Amuc_0904, a previously uncharacterized A. muciniphila outer membrane protein, was identified to induce goblet cell differentiation.

Mass spectrometry identification of Akkermansia muciniphila -Caco2 cells interaction proteins

Project description:Akkermansia muciniphila is recognized as a promising probiotic that improves the symptoms of a variety of diseases. However, the role and mechanism of A. muciniphila in regulating intestinal homeostasis remain to be explored. Here, we discovered that A. muciniphila was dramatically increased during colitis recovery, and its colonization greatly increased goblet cells to protect the intestinal barrier in mice. Amuc_0904, a previously uncharacterized A. muciniphila outer membrane protein, was identified to induce goblet cell differentiation.We want to find the receptors that 904 interacts with cells to explore the detailed mechanism.

Akkermansia muciniphila proteome.

Project description:Akkermansia muciniphila, a common member of the human gut microbiota, is considered to be a beneficial resident of the intestinal mucus layer. Surface-exposed molecules produced by this organism likely play important roles in colonization and communication with other microbes and the host, but the protein composition of the outer membrane has not been characterized thus far. Herein we identify A. muciniphila proteins after enrichment and fractionation of the outer membrane proteome of A. muciniphila.

Akkermansia muciniphila secretome

Project description:In this study, we attempted to identify a new probiotic effector molecule of A. muciniphila that plays a role in modulating host cells through secretome analysis. We performed proteomic profiling of secretome of A. muciniphila cultivated under basal medium and BHI medium (supplemented with 0.2% mucin) using nanoflow liquid chromatography-tandem mass spectrometry (nLC-MS/MS).

Binding of Akkermansia muciniphila to mucin is O-glycan specific

Project description:The intestinal anaerobic bacterium Akkermansia muciniphila is specialized in the degradation of mucins, which are heavily O-glycosylated proteins that constitute the major components of the mucus lining the intestine. Despite that adhesion to mucins is considered critical for the persistence of A. muciniphila in the human intestinal tract, our knowledge of how this intestinal symbiont recognizes and binds to mucins is still limited. Here, we first show that the mucin-binding properties of A. muciniphila are independent of environmental oxygen concentrations and not abolished by pasteurization. We then dissected the mucin-binding properties of pasteurized A. muciniphila by use of a recently developed cell-based mucin array that enables display of the tandem repeats of human mucins with distinct O-glycan patterns and structures. We found that A. muciniphila recognizes the unsialylated LacNAc (Galβ1-4GlcNAc1-R) disaccharide selectively on core2 and core3 O-glycans. This disaccharide epitope is abundantly found on human colonic mucins capped by sialic acids, and we demonstrated that endogenous A. muciniphila neuraminidase activity can uncover the epitope and promote binding. In summary, our study provides insights into the mucin-binding properties important for colonization of a key mucin-foraging bacterium.
