Transversal Research

Responsable : Clarisse Vandebrouck


Within STIM laboratory, the discovery that Cystic Fibrosis cells were lipointoxicated led to opening a new field of research and to patents which then permitted the creation in 2016 of a Spin-off by Dr Thierry Ferreira (Conic Meds). Conic Meds and STIM then created the cooperative laboratory « Lipointoxication and Channelopathies » LitCh that developed its R&D in particular with previous TIRC and TIME teams on cardiopathies and cystic fibrosis. Four scientists belonging to STIM laboratory devoted part of their work time to LitCh laboratory activity, including Clarisse Vandebrouck who has becoming the head of this cooperative laboratory.

In the approach of the PRéTI laboratory, the cooperative laboratory LitCh has been transformed into a global approach aiming at developping transversal research between the different axes.

Lipointoxication of various cellular models remains of high interest in this context.

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.

We will continue our joint research on lipo-intoxication in accordance with the three models of the PRéTI laboratory.
