Nous avons pour la rentrée 2021 quatres potentielles offres de financements de thèse dans le laboratoire:
A recent experimental study, directed by D Guerrout, published in Front Mol Biosci , describes the beneficial cardiac impact, on both diastolic and systolic functions, of blocking soluble epoxide hydrolase (sEH) during chronic kidney disease (CKD) induced by 5/6 nephrectomy (Nx) in mice. These beneficial effects may be mediated by the prevention of endothelial dysfunction, independent from kidney preservation and antihypertensor effect. Thus, inhibition of sEH holds a therapeutic potential in preventing type 4 cardiorenal syndrome.
Coraline Heron, a 1st year PhD student in the laboratory, has together with our collaborator, David Godefroy (Inserm U1239), used light sheet imaging to reveal the delicate network of cardiac lymphatics in mice. Their work was awarded with a 1st Prize at the yearly FASEB BioArts competition in 2020.

Some concerns about the prescription of drugs acting on the renin-angiotensin system (RAS) have emerged due to SARS COV2 and COVID-19 pandemic and the revelation of the fundamental role of ACE2 (angiotensin-converting enzyme 2) in COVID-19 infection. Indeed, SARS COV2 utilizes ACE2 as a membrane receptor to enter target cells. Consequently, the question arises whether RAS modulating drugs impact the risk of developing severe or fatal severe acute respiratory syndrome in case of COVID-19 infection. Here we discuss the evidence avilable on the impact of angiotensin-converting enzyme 1 inhibitors (ACEi) versus angiotensin II type 1 receptor blockers (ARB). Based on the currently available evidences, and as recommended by several medical societies, ACEi or ARB should not be systematically discontinued because to date no safety signal was raised with the use of these drugs.

Research performed in Inserm U1096 Unit in Rouen, concerns evaluation of the mechanisms behind and novel treatments of cardiovascular diseases, focusing on vascular protection and improvement of cardiac contractile function. This research is transversal, and performed both in experimental models and in human.
Our work mostly concerns the protection of vascular endothelial cells in the context of cardiovascular risk factors or cardiovascular diseases (hypertension, diabetes, myocardial infarction, heart failure etc. ). We also investigate new biotherapy approaches for stimulation of cardiac angiogenesis and lymphangiogenesis.
Development and assessment of new treatments of heart failure, as well as the clinical evaluation of percutaneous aortic valve replacement.
