A Specific Collagen Hydrolysate Improves Postprandial Glucose Tolerance in Normoglycemic and Prediabetic Mice and in a First Proof of Concept Study in Healthy, Normoglycemic and Prediabetic Humans.

In response to nutrients, intestinal L- and K-cells naturally secrete glucagon-like peptide 1 (GLP-1). GLP-1 regulates postprandial blood glucose by increasing insulin secretion, slowing down gastric emptying and inducing satiety. A selection of specifically developed collagen hydrolysates was screened for their ability to enhance natural GLP-1 production in vitro.

High pathogenic avian influenza A(H5) viruses of clade 2.3.4.4b in Europe-Why trends of virus evolution are more difficult to predict.

Since 2016, A(H5Nx) high pathogenic avian influenza (HPAI) virus of clade 2.3.4.

Improvement of NASH and liver fibrosis through modulation of the gut-liver axis by a novel intestinal FXR agonist.

Farnesoid X receptor (FXR) plays a pivotal role in the regulation of bile acid homeostasis and is involved in the pathogenesis of nonalcoholic steatohepatitis (NASH). Although FXR agonists effectively alleviate pathological features of NASH, adverse effects such as disturbance of cholesterol homeostasis and occurrence of pruritus remain to be addressed. Here, we identified a novel FXR agonist, ID119031166 (ID166), and explored the pharmacological benefits of ID166 in the treatment of NASH.

Molecular imaging of liver inflammation using an anti-VCAM-1 nanobody.

To date, a biopsy is mandatory to evaluate parenchymal inflammation in the liver. Here, we evaluated whether molecular imaging of vascular cell adhesion molecule-1 (VCAM-1) could be used as an alternative non-invasive tool to detect liver inflammation in the setting of chronic liver disease. To do so, we radiolabeled anti-VCAM-1 nanobody (Tc-cAbVCAM1-5) and used single-photon emission computed tomography (SPECT) to quantify liver uptake in preclinical models of non-alcoholic fatty liver disease (NAFLD) with various degree of liver inflammation: wild-type mice fed a normal or high-fat diet (HFD), FOZ fed a HFD and C57BL6/J fed a choline-deficient or -supplemented HFD.
