Vascular Biology Group
Goal: To identify pathways linking inflammation and thrombosis and to develop novel therapeutics targeted to specific vascular beds.
Blood fluidity is maintained by endothelial surface proteins, vasodilators secreted by endothelial cells and inhibitors of coagulant cascades. Inflammatory conditions, autoimmune diseases and ischaemic injury alter the vascular bed making it prothrombotic and amplify organ damage in a positive feed-back loop. Our group has identified an essential role for endothelial phosphohydrolase ‘NTPDase, CD39’ in the maintenance of endothelial function in the context of ischaemic, oxidative and immune-mediated activation. We have developed novel endothelial-targeted therapeutics with specificity to activated vascular beds thereby delivering benefit with minimal systemic bleeding compromise. We are exploring the role of purinergic nucleotides (ATP, ADP, adenosine) and complement proteins in the causation of thrombosis and miscarriages in patients with Lupus (SLE), antiphospholipid syndrome (APS) and thrombotic microangiopathy (TMA).
We are developing state-of-art platforms based on microfluidic technology to screen chemical libraries for antithrombotic potential and develop point-of-care devices for the diagnosis and management of haemostatic disorders.
