Prof. Dan Cuthbertson

Professor of Medicine, University of Liverpool,
United Kingdom

Dan Cuthbertson (BSc PhD FRCP) was appointed as a Professor of Medicine at the University of Liverpool in December 2018. He has worked at the University of Liverpool and Liverpool University NHS Foundation Trust as a Clinical Academic/Consultant Physician since 2007 with a major interest in obesity-related complications including non-alcoholic fatty liver disease (NAFLD), polycystic ovary syndrome and obstructive sleep apnoea.

His particular focus has been studying  the impact of multi-organ ectopic fat, particularly visceral fat, liver and pancreatic fat on metabolic processes including multi-organ (hepatic and peripheral) insulin resistance, beta cell function and the interrelationship with cardiovascular disease. He utilises multi-parametric MRI imaging to perform tissue characterisation assessing fat and fibrosis of these organs, coupled with stable isotope methodology to dynamically track fat and carbohydrate metabolism. These methodologies have been implemented to evaluate the impact of lifestyle interventions (structured exercise, imposed sedentary time, low calorie diet) and pharmacological interventions.

His talk will provide an overview of the implications of liver fat and liver fibrosis to the general population and frame NAFLD as a systemic, multi-organ disease with prominent extra-hepatic complications. He will briefly describe various dietary and pharmacological treatment options available.

Assoc. Prof. Guillaume de Lartigue

Assoc. Prof. Ana Domingos

Associate Professor of Neuroscience, Dept. Physiology, Anatomy, Genetics at University of Oxford; Wellcome IRScholar Member of the Advisory Board of Cell Metabolism, United Kingdom

Ana Domingos is an Associate Professor at the University of Oxford. After studying undergraduate Mathematics in Lisbon and Paris, she went to The Rockefeller University in New York City for her doctoral neurobiology studies with Leslie Vosshall and postdoc with Jeffrey Friedman, investigating how the hormone leptin affects neurocircuitry underlying food choices in mouse models of obesity. 

Her current research interests in neuroimmunometabolism started in her first lab at the Gulbenkian Institute four years before Oxford. Her laboratory discovered the sympathetic neuro-adipose junction, a functional synapse-like connection between white adipocytes and the sympathetic nervous system (Cell, 2015). They demonstrated that adipose sympathetic neurons are necessary and sufficient for fat mass reduction via norepinephrine (NE) signalling. They are the peripheral efferent arm in the neuroendocrine loop of leptin action in the brain (Cell, 2015 and Nature Communications, 2017). They then discovered Sympathetic neuron-Associated Macrophages (SAMs) that contribute to obesity by importing and metabolizing NE (Nature Medicine, 2017). These findings inspired the development of a new class of anti-obesity compounds named sympathofacilitators, which do not enter the brain nor have the typical cardiovascular or behavioural side effects of centrally acting sympathomimetic drugs (Cell Metabolism, 2020). 

Her lab wants to map neuroimmune mechanisms regulating autonomic function, and understand their implications in obesity. Ana Domingos is a member of the advisory board of Cell Metabolism, a member of the board of reviewing editors of eLife, the editor-in-chief of the American Journal of Physiology (AJP) – Endocrinology and Metabolism, published by the American Physiological Society. She has received awards from HHMI, Wellcome, ERC, HFSP, and EMBO.

Assoc. Prof. Camilla Scheele

Associate Professor, Novo Nordisk Foundation Center for Basic Metabolic Research, University of Copenhagen, Denmark 

Camilla Scheele is an Associate Professor at the Novo Nordisk Foundation Center for Basic Metabolic Research at the University of Copenhagen, Denmark. Prof. Scheele received her PhD at Karolinska Institutet in Stockholm, Sweden.

Her research focus concerns human brown fat, its potential to counteract obesity and type 2 diabetes and its role in human metabolism. Her research team characterized human supraclavicular brown fat and demonstrated, for the first time, that brown fat precursor cells can be isolated from adult humans and differentiated in vitro while maintaining features of brown fat. They further concluded that human brown fat is a heterogeneous tissue and are now establishing single cell methods to further understand the differentiation, function and subtypes of human brown fat cells. Another major research interest of her group is to identify adipokines specifically secreted from brown fat, with the hypothesis that there are yet unknown brown adipokines, i.e. batokines, with an important role in regulating human metabolism and brown fat differentiation. In 2020, Prof. Scheele was awarded an ERC consolidator grant to study peptide-mediated crosstalk between BAT and brain.
