Background: Adipose tissue is an important endocrine organ. Its secretion profile is robustly changed in the context of obesity fueling the development of comorbidities such as insulin resistance, diabetes mellitus type 2, and atherosclerosis. We have recently shown that the adipose tissue expression of the death ligand TNF-Related Apoptosis-Inducing Ligand TRAIL and its receptors is upregulated in obesity.Objective and Hypotheses: In this project, we in...

Background: Obesity is tightly associated with adipose tissue inflammation. Tumor necrosis factor-alpha (TNFα) has been identified as a key player in this inflammatory process and has been linked to the development of obesity-associated insulin resistance. Our group studies the involvement of TNF superfamily members in obesity-induced alterations in adipose tissue.Objective and hypotheses: Here, we aimed to identify the effects of the TNF superfamil...
