Endothelial cell behaviours in vascular health and disease (360G-Wellcome-205099_Z_16_Z)

<p>At the interface between blood and tissues, vascular endothelial cells (ECs) provide signalling hubs for vascular adaptation to physiological needs. Quiescent ECs form a non-thrombotic surface that facilitates the exchange of gases, molecules and cells between blood and tissues, but they respond to hypoxia-induced signals with vascular expansion and regulate leukocyte extravasation in response to injury. Our unpublished observations indicate that the cell surface receptor neuropilin 1 (NRP1) relays signals from the extracellular environment to the endothelial nucleus to enable such context-dependent responses. Thus, we hypothesise that NRP1 integrates growth factor and extracellular matrix signalling with gene transcription programmes to balance EC behaviours that enable vascular growth and to prevent the senescent and proinflammatory endothelial phenotype common to many chronic diseases. To determine how vascular growth and homeostasis depend on NRP1-mediated pathways, we will investigate novel mechanisms by which NRP1 conveys signals for tissue vascularisation, protects ECs from premature senescence and regulates gene transcription for vascular growth and homeostasis. The knowledge gained will significantly advance our understanding of how extracellular signals are integrated with gene regulation to control EC behaviour, and will likely uncover pathways for therapeutic intervention in diseases with vascular dysfunction.</p>
