Hepatic lipid overload triggers biliary epithelial cell activation via E2Fs

Johan Auwerx, Kristina Schoonjans, Alessia Perino, Antoine Jalil, Giovanni Sorrentino, Ece Yildiz, Gaby El Alam

During severe or chronic hepatic injury, biliary epithelial cells (BECs) undergo rapid activation into proliferating progenitors, a crucial step required to establish a regenerative process known as ductular reaction (DR). While DR is a hallmark of chronic ...

L-Cell Differentiation Is Induced by Bile Acids Through GPBAR1 and Paracrine GLP-1 and Serotonin Signaling

Kristina Schoonjans, Giovanni Sorrentino

Glucagon-like peptide 1 (GLP-1) mimetics are effective drugs for treatment of type 2 diabetes, and there is consequently extensive interest in increasing endogenous GLP-1 secretion and L-cell abundance. Here we identify G-protein-coupled bile acid receptor ...

Mechano-modulatory synthetic niches for liver organoid derivation

Kristina Schoonjans, Matthias Lütolf, Giovanni Sorrentino, Saba Rezakhani, Ece Yildiz

The recent demonstration that primary cells from the liver can be expanded in vitro as organoids holds enormous promise for regenerative medicine and disease modelling. The use of three-dimensional (3D) cultures based on ill-defined and potentially immunog ...

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 ...

Three dimensional models of tissue fibrosis

Matthias Lütolf, Kristina Schoonjans, Giovanni Sorrentino, Saba Rezakhani, Ece Yildiz

The invention provides a method for obtaining a three-dimensional (3D) cellular model of tissue fibrosis, such as liver fibrosis, comprising culturing epithelial cells in a 3D hydrogel in conditions suitable for a three-dimensional cellular cluster formati ...

Sterol regulatory element binding protein 1 couples mechanical cues and lipid metabolism

Giovanni Sorrentino

Sterol regulatory element binding proteins (SREBPs) are a family of transcription factors that regulate lipid biosynthesis and adipogenesis by controlling the expression of several enzymes required for cholesterol, fatty acid, triacylglycerol and phospholi ...
