Dietary modulation of adipose tissue and cardiometabolic health
Studies described in this thesis have increased our understanding of nutrient handling by brown adipocytes. We also generated immortalized brown adipocytes which can be used for future research. Furthermore, we gained more insight into the development of diet-induced obesity; feeding a high fat diet (HFD) rapidly made BAT insulin resistant and less active. In addition, HFD feeding increased synthesis of so-called endocannabinoids in both white and brown adipose tissue. Because...Show moreObesity has a great societal impact as it contributes to the development of type 2 diabetes and cardiovascular diseases. Activation of brown adipose tissue (BAT) is seen as a strategy to combat adiposity and related disorders, because of its capacity to combust nutrients and increase energy expenditure. To develop novel BAT activating methods, a better understanding of the pathophysiology of diet-induced obesity on BAT function and whole-body metabolism is required.
Studies described in this thesis have increased our understanding of nutrient handling by brown adipocytes. We also generated immortalized brown adipocytes which can be used for future research. Furthermore, we gained more insight into the development of diet-induced obesity; feeding a high fat diet (HFD) rapidly made BAT insulin resistant and less active. In addition, HFD feeding increased synthesis of so-called endocannabinoids in both white and brown adipose tissue. Because endocannabinoids regulate both energy intake and expenditure, future research should determine whether inhibiting endocannabinoid signaling specifically in adipose tissue is a worthwhile strategy to pursue in combating obesity. Finally, quercetin, which naturally occurs in fruits and vegetables, induced ‘browning’ of white adipose tissue and thereby improved blood lipid levels. These studies pave the road for further development of BAT-activating strategies!Show less
