Neurotensin is expressed throughout the gastrointestinal tract and acts as a gut hormone. Recent work has established neurotensin modulates lipid absorption at the gastrointestinal lumen, but its role in the control of glucose homeostasis remains unclear. Neurotensin acts via three receptors, including the NtsR1 and is endogenously released following the ingestion of olive oil. Previous work in our group has identified that neurotensin acutely improves glucose tolerance in bot...

The gut plays an important role in energy homeostasis, and gut function is under intensive neuroendocrine control. The non-invasive imaging techniques contrast enhanced ultrasound (CEUS) imaging and super resolution ultrasound (SRUS) have the potential visualise the gut and provide novel insight into its structure and function. We aimed to demonstrate that changes in duodenal villi structure can be monitored using CEUS and SRUS, providing an insight into the structural of the ...

Defending body weight is a fundamental homeostatic process. Indeed, countless studies have demonstrated weight-maintaining hyperphagia in response to either increased energy expenditure or a reduction in the caloric density of available food. The principal effector of this adaptive food intake is thought to be the adipose tissue-derived hormone, leptin. According to the classical ’adipostat’ model, the hypoleptinemia resulting from weight loss drives food intake to r...
