Full textSleep deprivation is associated with an increase in sympathetic nervous system activity, blood pressure (BP) and pro-inflammatory status that may induce endothelial dysfunction, a key factor in the development of cardiovascular diseases. Mechanisms that link endothelial dysfunction to total sleep deprivation (TSD) are not actually known. The aim of our work was to assess the impact of TSD on vasomotricity and relationships with BP changes and immuno-inflammatory responses. In the first part, we observed, in healthy young men, that 40 hours TSD induce a decrease of acetylcholine (ACh)-induced vasodilatation and an increase in plasma levels of endothelial activation markers. This endothelial dysfunction appeared before the increase in BP and sympathetic activity and was associated with higher plasma levels of TNF-α, and TNF-α mRNA levels in white blood cells. In a second study, we showed that 29 hours TSD induce a decrease in digital skin temperature and vascular conductance during a cold water immersion test (30 min, 5°C bath) and during the subsequent passive rewarming. This decrease of local tolerance to cold, found without modification in BP and central temperature, was associated with an increase of plasma levels of endothelin-1. In the second part, we demonstrated that the decrease of endothelial- and current- induced vasodilation observed after 24 hours of awaking were independent of BP changes, in sympathectomised (reserpined) rats. We also observed a decrease of NO and prostacyclines (PGI2) pathways activity after TSD. These results were associated with an increase in plasma levels of TNF-α, and IL-6. In conclusion, our results suggest that TSD, in healthy subjects, is a sufficient stress to trigger an endothelial dysfunction and low grade inflammation, leading to a decrease in vascular reactivity. This phenomenon is initially independent on changes in BP and sympathetic activity and is the consequence of immuno-inflammatory responses

Full textEssential hypertension is a polygenic trait. Discovered genetic variants were shown to have small effects, consequently explaining a tiny fraction (1%) of its phenotypic variation and resulting to a missing heritability. The missing heritability could be explained by gene-gene, gene-environment interactions and DNA methylation. Once conducted, these approaches should be further complemented by transcriptomic analyses, and thereby to reveal the involved molecular pathways. Therefore, we have shown that rs6046G>A in F7 interacted with rs5355C>T in SELE in order to influence systolic blood pressure levels. In the same direction, we have reported two other gene-gene interactions. We have also found the intergenic SNP rs7556897T>C, located between SLC19A3 and CCL20 locus, interacting with obesity in order to influence diastolic blood pressure. In parallel to those studies, we have shown that rs5030878T>C in FPR1 and KL-VS allele in Klotho may be implicated in BP regulation through their interaction with age and antihypertensive drugs respectively. We have also participated to the identification of a novel SNP, the rs2000999G>A explaining up to the half of haptoglobin?s heritablilty, a protein currently under investigation for its antihypertensive role. Finally, we proposed a new category of functional genetic-epigenetic biomarkers, the eMethSNPs. In conclusion, the identified 'functional' interactions show that low-level inflammation is involved in blood pressure regulation

Full textThe central regulation of arterial pressure (AP) involves activation of angiotensin II receptors type 1 (AT1R) in specific brain area of the hypothalamus and brainstem. The thesis studies involve modulation of brain AT1R using genetic and hypertensive mice combined with a telemetry system to record AP. The mouse model expressing a gain of function of the AT1R subtype A (AT1AMUT) showed high AP and reduced cardiac baroreflex sensitivity, but a normal circadian cardiovascular rhythm. The role of AT1R in the AP level of the genetic hypertensive mouse (BPH/2J) was examined and found to be similar to normotensive mice. However, in BPH/2J mice AT1R are important for the cardiac baroreflex and pressor responses to stress. These findings led to a targeted analyse of this receptor in the caudal ventrolateral medulla (CVLM) which is known for its role in baroreflex control. In the mice lacking the gene coding the AT1R, the expression of its subtype A, obtained by viral transgenesis in the CVLM, reduced the pressor response to an emotional stress and reduced the baroreflex sensitivity during the day period. These findings indicate the importance of the brain renin angiotensin system through activation of AT1R which modulates the sympathetic contribution to blood pressure control at a number of levels within the central nervous system. Of particular importance is the modulation of baroreflex control and the sympatho-inhibitory actions during emotional stress both of which occur within the ventral medulla

Full textHypertension is a disease due to multiple genetic and environmental factors. Many cardiovascular diseases are associated. During my PhD thesis, I addressed three aspects of the regulation of blood pressure in vivo and in vitro. In the first part, I studied the role of angiotensin II AT1 receptor activation in the development of fibrosis, independently of hypertension. I used animal and cellular models (MEF, HEK293, H295) expressing a constitutively active receptor. The results show that the mutant mice did not develop cardiac or renal fibrosis in a pure C57Bl6 strain. Furthermore, their moderate hypertension has not been normalized with two antihypertensives. The pure C57BL6 genetic background seems to be the cause of this moderate phenotype. Furthermore, MEF cells are not a good model to study fibrosis induced by angiotensin II. Only osteopontin is a marker induced by expression of the mutant receptor. As the mouse models and despite of their originality, these cellular models appear to be inappropriate to study AngII-dependent fibrosis. These limitations together with the weakness of the AT1 mutant phenotype lead to us to stop this project. In the second part of my thesis, a collaborative study allows us to show that Wnk1-haploinsufficiency in mice is responsible for a strong and transitory resistance to angiotensin II (AngII)-induced hypertension associated with a significant reduction of cardiovascular remodeling and a preservation of renal function and aldosterone release. Mechanistically, we unravel a critical role for Wnk1 in the activation of the phosphorylation of Mypt1, a known marker of the Rho-kinase pathway activity. Wnk1-haploinsufficient mice display a significant and transitory decrease of AngII-induced phospho- Mypt1 in the aorta, concomitant to the hypertension-resistance. Importantly, we further evidence that, in the vasculature, AngII chronic infusion induces a significant upregulation in Wnk1 gene expression which causes in vitro a significant increase in Mypt1 phosphorylation independently of spak activation. Our results provide new insight into the downstream vascular signaling pathway of AngII and unravel a previously unsuspected mechanism linking Wnk1 to hypertension and vascular remodeling. In the last part, I studied the role of vascular Cullin3 (Cul3) in the development of hypertension. Mutations in this gene have been recently identified as responsible for a familial hypertension with hyperkalaemia, FHHt. The Cul3 gene encodes an important and ubiquitous ubiquitin scaffold protein participating to a protein degradation complex (CRL3). The Rho-kinase pathway plays a major role in vascular tone and its regulation by relaxing or vasoconstricting agents. Recent studies suggest that the degradation of RhoA involves the CRL3 complex. I started to analyze the structural and functional links between this ubiquitination complex and the Rho kinase pathway in cellular models to explain all or part of the molecular mechanisms leading constitutional mutations of Cul3 gene to produce hypertension. I have shown that the Cul3Δ9 mutant presents an increased neddylation compared to the wild form and mofications of its affinity for some adaptors. However, in this preliminary work, its interactions with and its role in the degradation of RhoA have not been demonstrated yet. This PhD thesis has helped to address several aspects of the pathophysiology of the vessels and the role of angiotensin II in these regulations using modern tools, original mouse and cell line models. This has particularly highlighted a new target of angiotensin II and a new WNK1 vascular role

Full textThe K+-Cl− cotransporter type 3 (KCC3) is an ion transporter that belongs to the cation-Cl− cotransporter family and that probably plays an important role in blood pressure (BP) regulation. To determine how it accomplishes this role more specifically, we have characterized the cardiovascular phenotype of a Kcc3−/− mouse model through detailed analyses. We have found that this model distinguished itself from the wild-type animals by lower pulse pressure and heart rate, higher diastolic BP, lower in vitro reactivity of their aorta to adrenergic stimulation, higher ventricular mass, higher aldosterone levels in the absence of renin suppression and various neurologic abnormalities. These observations suggest that the hemodynamic disorders identified in the Kcc3−/− mouse model are due in part to the absence of KCC3 in the wall of different vessel types, leading to higher peripheral vascular resistance and aortic distensibility.
