Wellcome-MRC Institute of Metabolic ScienceResearch Interests
Research Vision
Our goal is to develop new treatments for people living with severe obesity by delivering a step-change in our understanding of the control of human energy balance.
Severe Childhood Obesity
Previously, we have demonstrated that mutations disrupting the hormone leptin and its downstream neural targets cause severe childhood obesity. In clinical studies, we have demonstrated the critical role of this pathway in food intake, food reward and fat preference. Our current work builds on this framework to obtain a deeper understanding of the genetic, molecular and physiological mechanisms that control human energy homeostasis.
With the help of many international collaborators, we have recruited over 7000 people with severe childhood onset obesity to the Genetics of Obesity Study (GOOS) (www.goos.org.uk). We use a number of genetic approaches to identify networks of genes and the molecular mechanisms they perturb. We undertake physiological studies in patients and volunteers to examine the role of the relevant molecules in eating behaviour, energy expenditure and peripheral metabolism. In this work, we benefit hugely from the Translational Research Facility (TRF) (www.mrl.ims.cam.ac.uk/research/core-facilities/wellcome-mrc-ims-translational-research-facility-trf/)
Thinness
We are also interested in understanding how and why some people remain thin in an obesogenic environment. Thinness (BMI<18kg/m2) is as heritable as severe obesity. We have recruited a UK cohort of 4000 thin people (STILTS cohort; www.stilts.org.uk) in whom we are undertaking genetic and physiological studies.
Translational Research
Our aim is to deliver treatments that will benefit people with severe obesity and use new knowledge to reduce weight stigma and discrimination. To that end, we work with a patient advocacy group, Obesity Empowerment Network (https://oen.org.uk/) and other partners. We developed new diagnostics for a range of obesity syndromes and an NHS Obesity Gene Panel is now available for use by Physicians in the UK (https://www.england.nhs.uk/publication/national-genomic-test-directories/). We treat patients with congenital leptin deficiency from around the world. We are running clinical trials administering Setmelanotide (a melanocortin 4 receptor agonist) in patients with several genetic obesity syndromes and work with other companies in drug discovery and trials.
We are working with colleagues at the MRC Toxicology Unit, Dept of Medicine and Babraham Institute to study immune responses to the SARS CoV-2 vaccine in people with severe obesity (https://scorpiostudy.org.uk/).
