Compartmentalization of GABA synthesis by GAD67 differs between pancreatic beta cells and neurons

Chiara Cianciaruso, Edward Allen Phelps, Steinunn Baekkeskov Hanahan

The inhibitory neurotransmitter GABA is synthesized by the enzyme glutamic acid decarboxylase (GAD) in neurons and in pancreatic β-cells in islets of Langerhans where it functions as a paracrine and autocrine signaling molecule regulating the function of i ...

Robust T1-Weighted Structural Brain Imaging and Morphometry at 7T Using MP2RAGE

Tobias Kober, Patric Hagmann, José Pedro Rebelo Ferreira Marques, Gunnar Krüger, François Lazeyras, Alexis Roche, Kieran O'Brien

Purpose To suppress the noise, by sacrificing some of the signal homogeneity for numerical stability, in uniform T1 weighted (T1w) images obtained with the magnetization prepared 2 rapid gradient echoes sequence (MP2RAGE) and to compare the clinical utilit ...

The Digestive Tract of Drosophila melanogaster

Bruno Lemaitre

The digestive tract plays a central role in the digestion and absorption of nutrients. Far from being a passive tube, it provides the first line of defense against pathogens and maintains energy homeostasis by exchanging neuronal and endocrine signals with ...

The Receptor TGR5 Mediates the Prokinetic Actions of Intestinal Bile Acids and Is Required for Normal Defecation in Mice

Kristina Schoonjans

BACKGROUND & AIMS: Abnormal delivery of bile acids (BAs) to the colon as a result of disease or therapy causes constipation or diarrhea by unknown mechanisms. The G protein-coupled BA receptor TGR5 (or GPBAR1) is expressed by enteric neurons and endocrine ...

A Notch-dependent molecular circuitry initiates pancreatic endocrine and ductal cell differentiation

Anne Grapin-Botton

In the pancreas, Notch signaling is thought to prevent cell differentiation, thereby maintaining progenitors in an undifferentiated state. Here, we show that Notch renders progenitors competent to differentiate into ductal and endocrine cells by inducing a ...

Planar Cell Polarity Controls Pancreatic Beta Cell Differentiation and Glucose Homeostasis

Anne Grapin-Botton, Cédric Cortijo

Planar cell polarity (PCP) refers to the collective orientation of cells within the epithelial plane. We show that progenitor cells forming the ducts of the embryonic pancreas express PCP proteins and exhibit an active PCP pathway. Planar polarity proteins ...

Neurogenin3 Initiates Stepwise Delamination of Differentiating Endocrine Cells During Pancreas Development

Anne Grapin-Botton, Yung Hae Kim, Keiichi Katsumoto

During development, pancreatic endocrine cells are specified within the pancreatic epithelium. They subsequently delaminate out of the epithelium and cluster in the mesenchyme to form the islets of Langerhans. Neurogenin3 (Ngn3) is a transcription factor r ...
