Presentation of the research topic

Obesity has risen to reach epidemic proportions world-wide and predisposes to metabolic dysregulations, hence precipitating diseases such as dyslipidemia, MASLD and T2D. These metabolic disorders increase the risk for cardiovascular complications due to a combination of atherosclerosis of the coronary arteries and altered heart muscle and valve function, a condition often referred to as cardiometabolic disease. Cardiometabolic diseases are increasingly recognized to involve altered multi-organ interactions. Importantly, alterations in immune-inflammatory functions, the main focus of team 3, contribute to increase the cardiovascular risk and recent evidence has emerged showing that improper metabolic control acts in concert with immune system alterations to precipitate disease progression. It is thus important not only to study the role of individual organs in cardiometabolic disease, but also to study the role of altered inter-organ crosstalk including the key contribution of the immune system in this process. Thus, Team 3 studies the mechanisms of bidirectional crosstalk between the immune-inflammatory system and metabolism, in particular in the context of “metabolic” diseases: obesity, type 2 diabetes (T2D), MASLD and their cardiovascular complications, and in “inflammatory” diseases: psoriasis. Team 3 uses different complementary approaches, from bench-to-bedside (pre-clinical mouse models, in vitro molecular studies, translational research) focusing on immune cells from different metabolic organs (liver, heart, adipose tissues) as well as from their “classical” location in blood, bone marrow and barrier organs such as skin. Successful accomplishment of these objectives requires pluri-disciplinary competences and translational approaches. Therefore, Team 3 has developed its projects in close interaction with the other teams of the unit, allowing whole organism/systems biology approaches.
