Combatting metabolic disease : ethnic aspects, mechanisms and novel treatment strategies

Doctoral Thesis

Obesity, type 2 diabetes and cardiovascular diseases are major public health problems. South Asians are specifically at risk for the development of (cardio)metabolic diseases, due to a combination of known and unknown risk factors. Since effective long-term treatment strategies are currently lacking, the search for additional risk factors and development of targeted treatment strategies to combat these (cardio)metabolic diseases is warranted. An attractive approach seems to be activation of energy-combusting brown adipose tissue (BAT), which can result in increased energy expenditure and improvement in glucose and lipid metabolism. In this thesis, we aimed to address two key objectives: 1) unravelling the underlying mechanisms that could explain the increased predisposition for metabolic disease in the South Asian population, and 2) identifying novel pharmacological strategies that activate BAT and increase energy expenditure in risk populations, including South Asians and individuals with overweight and prediabetes. The studies described in this thesis have highlighted some novel factors, such as endocannabinoids and angiopoitein-like-protein-4, that might in part explain to unbeneficial metabolic phenotype of South Asians. In addition, novel potential therapeutic strategies were identified to combat metabolic disease, such as treatment with a β3-adrenergic receptor agonist and a dipeptidyl-peptidase-4 inhibitor.
