    Beside large conductance arteries, arterioles, the small resistance arteries located upstream capillaries control blood delivery to tissues at relevant flow and pressure. Disorders in their structure and function can raise downstream capillary pressure, which induces organ damage, and can participate upstream to increased blood pressure and cardiovascular risk. The endothelium has a key role in the control of local blood flow by resistance arteries. Flow (shear stress) induces the production of vasodilators by endothelial cells leading to flow-mediated dilatation (FMD). Reduced FMD is the hallmark of endothelium dysfunction. FMD is altered early in ageing especially when associated with cardiometabolic risk factors. Women are protected against cardiovascular disorders compared to men. Nevertheless, a unique case of lack of ERα described in a man was associated with early atherosclerosis and a selective loss of FMD. We have shown that estradiol and endothelial estrogen receptor alpha (ERα) are involved in atheroprotection and flow-mediated outward remodeling (FMR, or collateral arteries growth in ischemic diseases). We also began to decipher the respective roles of classic nuclear, transcriptional ERα and of a more recently characterized extranuclear membrane ERα. We hypothesize that membrane ERα is an important actor of endothelial mechanotransduction (shear stress signaling) and propose to determine its role in the RAs homeostasis. This project is supported by the National Agency for Research (ANR).

    Besides the estrogen receptor, circulating and tissue lipids such as sphingosine-1-phosphate (S1P) are potent regulators of vascular homeostasis. S1P is an abundant plasma lipid that is carried on high-density lipoproteins (HDL) and that mediates in part their vascular protective functions through activation of G protein-coupled receptor signaling. S1P signaling is essential for the integrity of the cardiovascular system. A growing body of evidence suggests that S1P may sustain pressure-induced (myogenic) tone and mediate endothelial shear stress sensing and dilatation in resistance arteries. Using mouse lines engineered for temporal and spatial deficiency in S1P production and S1P receptors, we will address the potential of blood and vessel wall-derived S1P to modulate vascular function in isolated vessels and organs and in the intact organism. We expect finding how S1P signaling is engaged to regulate resistance artery function and blood pressure, and thus on the potential diagnostic value of blood S1P for microvascular health and the development of hypertension.

    Recent studies have shown the presence of estrogen receptors in mitochondria and suggested that estradiol alters mitochondrial function. We have demonstrated that in vivo estrogen replacement at physiological doses leads to increased levels of key mitochondrial proteins, such as cytochrome C, mitochondrial transcription factors and antioxidant enzymes, in cerebral blood vessels of ovariectomized female rats. Estrogens are potent regulator of mitochondria biogenesis and several recent studies suggest a role for the mitochondria in flow-mediated signaling. Taking advantage of the expertise of team 1 (Mitolab) we investigate the role of mitochondria dynamics in the response to shear stress of endothelial cells (Mitoshear project supported by the “Fondation pour la Recherche Médicale”.
