- Original description
Adipocytes play an important role in our body through their function as metabolic energy stores in the form of fat deposits, which are stored when metabolic energy is in excess and released when energy levels are low. In severe obesity, adipose tissue grows through the production of more adipocytes from stem cells (hyperplasia) and the increase in the size of existing adipocytes (hypertrophy). This ability of adipocytes, to maintain their functionality during tissue expansion, is critical in determining the development of obesity-related comorbidities. However, not all adipocytes are the same as adipocyte function differs greatly depending on the depot in which they are found. To elucidate the mechanisms underlying adipocyte adaptability, it is necessary to obtain a deep systems biology understanding of how signaling in different types of adipocytes regulates metabolism and function. Currently, this research group is conducting a systems biology analysis of adipocyte plasticity in obesity in mouse models, but adipose tissue biopsies from different depots in humans are lacking and needed to investigate the regulation of adipocyte function and plasticity in humans. Such studies of adipocytes are crucial for the understanding how obesity affects adipose tissue function and leads to comorbidities.Read full original descriptionShow less
