Transversal Research

Responsable : Clarisse Vandebrouck

Within the PRéTI laboratory, we have developed a transversal axis which currently includes two main themes:

A) Lipointoxication

Lipointoxications are characterized by an accumulation of saturated fatty acids in the membranes of the cells of our organism, which affects their proper functioning. The targeted diseases include obstructive respiratory diseases, such as Cystic Fibrosis and Chronic Obstructive Pulmonary Diseases (COPD), but also metabolic syndromes, responsible for Type 2 Diabetes, Hepatic Steatosis and certain cardiovascular diseases.

In the context of the new partnership with PRéTI, we continue the study of lipointoxication in connection with the models of investigations and pathologies studied by the PRéTI laboratory. Thus lipointoxication is addressed i) in cystic fibrosis and we have shown that human bronchial epithelial cells extracted from lungs of patients with Obstructive Pulmonary Diseases (OPDs), i. e. Cystic Fibrosis (CF) individuals and Smokers, display a characteristic lipointoxication signature, with excessive amounts of saturated phospholipids (PLs). Moreover, we have recently made an update on lipointoxication in cystic fibrosis in order to make a complete inventory of the subject; ii) in metabolic diseases and we have shown that fatty acids from the diet can redistribute within PLs in a very selective manner, with phosphatidylcholine being the preferred sink for this redistribution. Moreover, in the High-fat/high-fructose rat model, most organs are protected from this redistribution, at the expense of the liver and skeletal muscles. Interestingly, such a redistribution correlates with clear-cut alterations in the function of these organs (Bacle et al., DMM 2020) ; iii) in muscle where we have postulated that PolyUnsaturated Fatty Acids (PUFA)-containing PLs could be central players for muscle cell adaptation to mechanical constraints. By a combination of in cellulo and in silico approaches, we have shown that PUFA, and particularly the ω-3 DocosaHexaenoic Acid (DHA), regulates important properties of the plasma membrane that improve muscle cell resilience to mechanical constraints. Thanks to their unique property to contortionate within the bilayer plane, they facilitate the formation of Vacuole-like dilation (VLD) which, in turn, reduce membrane stress and avoid cell breakage under mechanical constraints.

B) Energy metabolism

The study of energy metabolism is the main focus of our research activities. As mitochondria play a major role in cellular energetics, we are particularly interested in the study of mitochondrial functions as well as in the understanding of the regulations of mitochondrial life cycle (mitochondrial biogenesis, mitochondrial dynamics and mitophagy). Within the PRéTI laboratory, our objective is to develop tools for the systematic study of energy metabolism in the study models of the laboratory. We plan to develop methods to analyze the energy metabolism of epithelial cells in order to study the possible impact of Trikafta® treatment on the mitochondrial alterations described in cystic fibrosis. Dr Piquereau will also offer his expertise in the study of the energy metabolism of the heart and skeletal muscle to help better understand the role of mitophagy in Duchenne muscular dystrophy and the alterations of the metabolism of cardiac fibroblasts in the context of lipointoxication. Ultimately, the idea is to develop an axis consisting in studying cellular energy metabolism that each member of the laboratory will be able to resort, in order to go further in the understanding of his respective study model.
