Microfluidic devices for automated analysis of ingested bacteria in the Caenorhabditis elegans intestine

In this thesis, we explored on-chip high-resolution imaging of the fate of intestinal bacteria and bacterial products in Caenorhabditis elegans (C. elegans). In the first part, we carried out high-resolution z-stack fluorescent imaging of Red Fluorescent P ...

Dietary Fiber Is Essential to Maintain Intestinal Size, L-Cell Secretion, and Intestinal Integrity in Mice

Kristina Schoonjans

Dietary fiber has been linked to improved gut health, yet the mechanisms behind this association remain poorly understood. One proposed mechanism is through its influence on the secretion of gut hormones, including glucagon-like peptide-1 (GLP-1) and gluca ...

Bile Acids Signal via TGR5 to Activate Intestinal Stem Cells and Epithelial Regeneration

Kristina Schoonjans, Alessia Perino, Maroun Bou Sleiman, Giovanni Sorrentino, Ece Yildiz, Gaby El Alam

BACKGROUND & AIMS: Renewal and patterning of the intestinal epithelium is coordinated by intestinal stem cells (ISCs); dietary and metabolic factors provide signals to the niche that control ISC activity. Bile acids (BAs), metabolites in the gut, signal nu ...

Biogeography and biochemistry of bile acid 7-dehydroxylation in the mammalian gut

Solenne Anne Marie Marion

Bile acids (BAs) are small molecules synthesized by the host and chemically modified by the microorganisms inhabiting the intestinal tract. The microbial transformation of BAs in the gut is critical to BA-mediated signaling as it modifies their amount and ...

Intestinal helminths modulate the gut microbiome

Alexis Rapin

Intestinal parasitic worms (commonly named intestinal helminths) affect close to one quarter of the world population and cause major losses for the livestock industry. These parasites establish chronic infections by modulation the immunity of their host. T ...

Immune Antibodies and Helminth Products Drive CXCR2-Dependent Macrophage-Myofibroblast Crosstalk to Promote Intestinal Repair

Duncan-Bruce Sutherland, Nicola Harris, Benjamin John Marsland, Beatrice Volpe, Julia Esser-von Bieren, Jérôme Bürgi

Helminth parasites can cause considerable damage when migrating through host tissues, thus making rapid tissue repair imperative to prevent bleeding and bacterial dissemination particularly during enteric infection. However, how protective type 2 responses ...

Emerging actions of the nuclear receptor LRH-1 in the gut

Johan Auwerx, Kristina Schoonjans, Pablo Jose Fernandez Marcos

Liver receptor homolog-1 (NR5A2) is a nuclear receptor originally identified in the liver and mostly known for its regulatory role in cholesterol and bile acid homeostasis. More recently, liver receptor homolog-1 has emerged as a key regulator of intestina ...
