In this project we aim to characterise the function of a new gut-derived peptide we have discovered in human plasma, named erusiolin, which we hypothesise plays a role in appetite regulation. With the global pandemic of obesity and its associated burden of metabolic disease, advances in our understanding of appetite regulation are critical to develop new effective therapies. Using a novel analytical approach, we have discovered and started characterisation of a new putative hormone called erusiolin. We hypothesise that erusiolin is a new hormone that acts in parallel with ghrelin to trigger food intake.

Program type



In this project, we will examine the role of erusiolin in controlling food intake in both healthy and diseased states using human samples and mouse models, which will allow us to detail the molecular mechanisms linking its secretion from the gut to appetite stimulation. These studies will enhance our understanding of appetite regulation and could lead to the development of novel therapeutic approaches aimed at reducing food intake in patients with obesity. The specific aims of this project are:

  1. Determine the effects of erusiolin perturbation (either loss, or gain) on animal behaviour including appetite and metabolism.
  2. Identify the erusiolin receptor to provide insight into the hormone's mechanism of action.
  3. Characterise the nutrient-dependent release of erusiolin into the blood of healthy and obese patients.
