Q: You stated during the presentation that, on balance, […]

  • Time For Better Microbiome Research


    The microbiome needs no introduction – it has been several years since you could pick up a biomedical research journal and not run into an article on possible connections of human gut bacteria and disease. There were thousands of such papers last year alone. But it’s a very hard field to work in. You can […]

  • Webinar Q&A — Validated Il10 Knockout Models for IBD Research


    Dr. Philip Dubé recently presented a webinar on validated Il10 knockout mouse models for IBD research. He gave an overview of research in this area and presented new data on these models from studies done by Boehringer Ingelheim and Incyte. Due to time constraints, many of the questions submitted during the webinar went unanswered. This […]

  • The emergence of microbiome centres


    As microbiome science expands, academic centres scramble to fill many needs, from service provider to industry liaison. A newly created network aims to share strategies and accelerate knowledge transfer, and invites others to join the efforts. Microbiomes — assemblages of interacting microorganisms, such as bacteria, archaea, fungi and viruses — are increasingly recognized as being […]

  • A purified membrane protein from Akkermansia muciniphila or the pasteurised bacterium blunts colitis associated tumourigenesis by modulation of CD8+ T cells in mice


    Abstract Objective Gut microbiota have been linked to inflammatory bowel disease (IBD) and colorectal cancer (CRC). Akkermansia muciniphila (A. muciniphila) is a gram-negative anaerobic bacterium that is selectively decreased in the faecal microbiota of patients with IBD, but its causative role and molecular mechanism in blunting colitis-associated colorectal cancer (CAC) remain inconclusive. This study investigates […]

  • Gut microbiota manipulation during the prepubertal period shapes behavioral abnormalities in a mouse neurodevelopmental disorder model


    Abstract Previous studies demonstrate an association between activation of the maternal immune system during pregnancy and increased risk of neurodevelopmental psychiatric conditions, such as schizophrenia and autism, in the offspring. Relatively recent findings also suggest that the gut microbiota plays an important role in shaping brain development and behavior. Here we show that maternal immune […]

  • Intratumoral accumulation of gut microbiota facilitates CD47-based immunotherapy via STING signaling


    Most studies focus on how intestinal microbiota influence cancer immunotherapy through activating gut immunity. However, immunotherapies related to innate responses such as CD47 blockade rely on the rapid immune responses within the tumor microenvironment. Using one defined anaerobic gut microbiota to track whether microbiota interact with host immunity, we observed that Bifidobacterium facilitates local anti-CD47 […]

  • It’s the fiber, not the fat: significant effects of dietary challenge on the gut microbiome


    Abstract Background Dietary effects on the gut microbiome play key roles in the pathophysiology of inflammatory disorders, metabolic syndrome, obesity, and behavioral dysregulation. Often overlooked in such studies is the consideration that experimental diets vary significantly in the proportion and source of their dietary fiber. Commonly, treatment comparisons are made between animals fed a purchased […]

  • Germ‐Free and Microbiota‐Associated Mice yield Small Intestinal Epithelial Organoids with Equivalent and Robust Transcriptome/Proteome Expression Phenotypes


    Abstract Intestinal epithelial organoids established from gut tissue have become a widely used research tool. However, it remains unclear how environmental cues, divergent microbiota composition and other sources of variation before, during and after establishment confound organoid properties, and how these properties relate to the original tissue. While environmental influences cannot be easily addressed in […]

  • Self-reinoculation with fecal flora changes microbiota density and composition leading to an altered bile-acid profile in the mouse small intestine


    ABSTRACT Background The upper gastrointestinal tract plays a prominent role in human physiology as the primary site for enzymatic digestion and nutrient absorption, immune sampling, and drug uptake. Alterations to the small intestine microbiome have been implicated in various human diseases, such as non-alcoholic steatohepatitis and inflammatory bowel conditions. Yet, the physiological and functional roles […]

  • Gut microbiota mediates intermittent-fasting alleviation of diabetes-induced cognitive impairment


    ABSTRACT Cognitive decline is one of the complications of type 2 diabetes (T2D). Intermittent fasting (IF) is a promising dietary intervention for alleviating T2D symptoms, but its protective effect on diabetes-driven cognitive dysfunction remains elusive. Here, we find that a 28-day IF regimen for diabetic mice improves behavioral impairment via a microbiota-metabolites-brain axis: IF enhances […]

  • Ursolic acid improves the bacterial community mapping of the intestinal tract in liver fibrosis mice


    ABSTRACT Liver fibrosis often appears in chronic liver disease, with extracellular matrix (ECM) deposition as the main feature. Due to the presence of the liver-gut axis, the destruction of intestinal homeostasis is often accompanied by the development of liver fibrosis. The inconsistent ecological environment of different intestinal sites may lead to differences in the microbiota. […]

  • Gastric bypass surgery in a rat model alters the community structure and functional composition of the intestinal microbiota independently of weight loss


    Abstract Background Roux-en-Y gastric bypass (RYGB) surgery is a last-resort treatment to induce substantial and sustained weight loss in cases of severe obesity. This anatomical rearrangement affects the intestinal microbiota, but so far, little information is available on how it interferes with microbial functionality and microbial-host interactions independently of weight loss. Methods A rat model […]
