Neurotensin is a 13-amino acid peptide expressed in both the brain and the gastrointestinal tract where it acts as a neuropeptide and gut hormone, respectively. Centrally, neurotensin plays a role in appetite, analgesia and thermoregulation, whereas peripheral neurotensin regulates lipid absorption, gastric emptying and exocrine pancreatic secretion. The role of neurotensin in the control of glucose homeostasis currently remains unclear. We found peripheral administration of n...

Dietary fat intake is an important source of energy and in excess can drive the development of obesity. Investigating how dietary fat intake alters neuronal activity in the brain and drives behavioural changes may help us understand the mechanisms behind high fat diet induced obesity. 2-oleoyglycerol (2-OG) is a naturally occurring unsaturated long chain fatty acid produced by fat digestion in the gut and a ligand of G protein-coupled receptor 119 (GPR119). Published data has ...

Background and Aims: β cell connectivity is a feature of pancreatic islets in vitro but its existence in vivo, when innervated and continuously perfused with blood, has not yet been demonstrated. We imaged islets engrafted in the anterior chamber of the mouse eye (ACE) to explore this question.Methods: Mouse (C57BL6, Ins1Cre::GCaM6mf/f) or human islets infected with adenovirus to express GCaMP6m, were engrafted and Ca<su...
