Force sensing mechanisms of haemostasis in heart failure and diabetes

Since the original identification of the role of PIEZO1 in vascular integrity and endothelial cell biology by our group in Leeds in 2014, there have been many publications on the role of PIEZO1 in endothelial function and its role in processes such as atherosclerosis, hypertension, cell-cell junctions, vascular permeability and leukocyte diapedesis. However, the vascular endothelium also plays an important role in maintaining blood flow through its anticoagulant properties.

<p>In cardiovascular disease and diabetes (cardiometabolic disease), the anticoagulant phenotype of endothelium can be lost, and the endothelium is capable of expressing procoagulant factors instead. In pilot studies, we found that endothelial PIEZO1 is downregulated in patients who have diabetes as well as heart failure. The hypothesis of this project is, therefore, that downregulated endothelial PIEZO1 is an unwanted feature of patients who suffer from cardiovascular disease and diabetes, increasing their risk of adverse thrombotic events. To address this hypothesis, the student will investigate the role of endothelial PIEZO1 in coagulant phenotype using samples obtained from relevant patients with ethical approval and informed consent. The student will isolate and culture endothelial cells and then analyse the expression of tissue factor, von Willebrand Factor and PAI-1 (procoagulant and antifibinolytic endothelial markers) on the one hand and thrombomodulin, TFPI and oxide expression on the other (anticoagulant and antiplatelet markers).</p> <p>The student will investigate the effects of novel small-molecule PIEZO1 modulators developed in our group at Leeds and use in vitro flow models to investigate the effects of such molecules in the presence of mechanical force. Together, these studies will establish the role of PIEZO1 in regulating anti- versus pro- coagulant phenotypes of the endothelium, potentially opening the way to new diagnostics and therapies.&nbsp;</p> <p><strong>To support the application process or if you want to know more about our non-clinical PhDs a recording of our 2023 webinar can be found via the links below</strong></p> <p><strong>**The deadline dates in the webinar are out of date but are correct in the stand-alone slide deck**</strong></p> <p><a href="https://www.findaphd.com/common/clickCount.aspx?theid=164726&amp;type=184&amp;DID=757&amp;url=https%3a%2f%2fwww.youtube.com%2fwatch%3fv%3djRE-3RqlCh8" rel="nofollow" target="_blank">NIHR Leeds BRC Non Clinical PhD Scheme webinar - YouTube</a></p> <p>with a copy of the slide deck used at</p> <p><a href="https://www.findaphd.com/common/clickCount.aspx?theid=164726&amp;type=184&amp;DID=757&amp;url=https%3a%2f%2fwww.youtube.com%2fwatch%3fv%3dQqQ5PbEdj-8" rel="nofollow" target="_blank">Leeds BRC Non Clinical PhD Webinar FINAL updated slide deck March 24 - YouTube</a></p> <p>&nbsp;</p>
