Differential temporal release and lipoprotein loading in B. thetaiotaomicron bacterial extracellular vesicles

Journal of Extracellular Vesicles
Bacterial extracellular vesicles (BEVs) contribute to stress responses, quorum sensing, biofilm formation and interspecies and interkingdom communication. However, the factors that regulate their release and heterogeneity are not well understood.

Transglycosylation Properties of a Novel α-1,4-Glucanotransferase from Bacteroides thetaiotaomicron and Its Application in Developing an α-Glucosidase-Specific Inhibitor

Journal of Chemistry, 2018
In this study, α-glucanotransferase from Bacteroides thetaiotaomicron was expressed in Escherichia coli and characterized. Conserved amino-acid sequence alignment showed that Bacteroides thetaiotaomicron α-glucanotransferase (BtαGTase) belongs to the ...

Gut Microbial Release of Ferulic Acid From Germinated Quinoa Alleviates Obesity‐Associated Cognitive Impairment by Activating Hippocampal Mitophagy Associated with PINK1/Parkin Pathway

Advanced Science, EarlyView.
Liberation of ferulic acid by gut microbial feruloyl esterase mediates cognitive enhancement of germinated quinoa (GQF) on obese mice. Ferulic acid enriched in GQF is released by gut microbes Roseburia hominis and R. intestinalis and subsequently mediates the neuroprotective effects of GQF on obesity‐induced cognitive decline by activating hippocampal ...

Activation of a Specific Gut Bacteroides-Folate-Liver Axis Benefits for the Alleviation of Nonalcoholic Hepatic Steatosis

Cell Reports, 2020
Summary: A beneficial gut Bacteroides-folate-liver pathway regulating lipid metabolism is demonstrated. Oral administration of a Ganoderma meroterpene derivative (GMD) ameliorates nonalcoholic hepatic steatosis in the liver of fa/fa rats by reducing ...

Fecal Microbiota Transplantation and Microbiota‐Based Therapeutics in Allogeneic Hematopoietic Stem Cell Transplantation: Current Evidence and Future Directions

Clinical Pharmacology &Therapeutics, EarlyView.
The intestinal microbiome is a key regulator of immune homeostasis, metabolism, and epithelial barrier integrity. In patients with malignant hematological diseases, particularly those undergoing hematopoietic stem cell transplantation, microbiome perturbations by reduced diversity, pathobiont expansion, and loss of beneficial metabolites are common as ...

Characterization of the role of glycine lipids in Bacteroides thetaiotaomicron [PDF]

, 2018
Abstract Acylated amino acids function as important components of the cellular membrane in some bacteria. Biosynthesis is initiated by the N-acylation of the amino acid and this is followed by subsequent O-acylation of the acylated molecule resulting in the production of the mature diacylated amino acid lipid. In this

Transfection of the Anaerobe Bacteroides thetaiotaomicron with Phage DNA [PDF]

Journal of General Microbiology, 1977
SUMMARY: The properties of a Bacteroides thetaiotaomicron phage, β1, are described. Phenol-extracted phage β1 DNA transfects Ca2+-treated B. thetaiotaomicron cells and transfection is not limited to a particular stage in the growth cycle. An obligatory step in the transfection procedure is a 33-fold dilution in broth, allowing replication of the ...

Microbiome—pancreatic cancer crosstalk: From tumor biology to therapeutic intervention

iMetaOmics, EarlyView.
The intratumoral microbiome acts as a critical regulator in pancreatic cancer progression and therapeutic resistance. This comprehensive review delineates the origins of pancreatic microbes, elucidates their multifaceted mechanisms in driving immune suppression, metabolic reprogramming, and stromal desmoplasia, and highlights the clinical potential of ...
