La fibrillation auriculaire et les veines pulmonaires

February 1, 2023 – 12:30 pm – School of Medicine (105) – Room 514

Abstract

Lorsque la pharmacothérapie échoue, l’ablation des veines pulmonaires reste une option pour traiter la fibrillation auriculaire symptomatique. Néanmoins, malgré cette intervention, 4 patients sur 10 ne seront pas guéris de leur arythmie. Une reconnexion électrique des veines pulmonaires est considérée comme étant la cause principale de cet échec. Cependant, il y a potentiellement d’autres facteurs impliqués. Ce séminaire sera une discussion autour de la physiopathologie de la veine pulmonaire et du rôle joué par l’étirement et les cicatrices rigides qui apparaissent à l’endroit des lésions d’ablation.

Characterization of RNA Splicing Factors Involved in Metabolic Regulation in the Liver

January 31, 2023 – 12:30 pm – School of Medicine (105) – Bordeaux room

Abstract
RNA splicing and alternative splicing expand the complexity and the regulatory potential of our genome. However, defects in these fundamental processes have been implicated in a growing number of human pathologies including liver disease. We will discuss recent advances and open questions about the contribution of RNA splicing and alternative splicing in metabolic homeostasis and inflammatory response in the liver.

Exploring the role of classical and non-classical biomarkers in the context of atherosclerotic burden

November 24, 2022 – 12:30 pm to 2:00 pm

room 514 – School of Medicine – 105 boulevard de l’Hôpital 75013 Paris

Abstract: Cardiovascular risk stratification is a clinical challenge. Although lifestyle interventions and pharmacological strategies lowering low-density lipoprotein cholesterol (LDL-C) have led to a reduction in atherosclerotic cardiovascular disease (ASCVD), even among those with controlled LDL-C, ASCVD events continue to occur frequently. Thus, there is a need to identify new biomarkers improving the risk prediction for cardiovascular events. On this matter, emerging evidence emphasizes the importance of extracellular vesicles in intercellular communication processes with key effects on cell survival, endothelial homeostasis, inflammation, neoangiogenesis and thrombosis. Another aspect worth considering is related to mitochondria. They are responsible for the production of adenosine triphosphate (ATP) and the regulation of nutritional metabolism, calcium homeostasis and cellular viability in several organs. Pertaining cardiovascular burden, accumulation of mitochondrial DNA damage and progressive respiratory chain dysfunction are associated with atherosclerosis or cardiomyopathy in human investigations and animal models of oxidative stress. Mitochondrial dysfunction can also result in apoptosis, favoring plaque rupture. The characterization of extracellular vesicles and the study of mitochondrial functionality could thus pave the way for a better cardiovascular risk prediction as well as for promising therapeutic strategy in atherosclerosis.
