Vascular ageing contributes to the age-dependent rise of hypertension and atherosclerotic diseases. Increased arterial stiffness and impaired vascular function are the two most clinically important events that occur with vascular ageing. Arterial stiffening and vascular function vary widely even among healthy middle-aged and older adults. This observation suggests that one, or most likely several, factors influence these vascular characteristics with adult ageing.
Our research is focused on molecular mechanisms of vascular dysfunction and vascular remodelling. Our group is particularly interested in the role of adipocyte eNOS (endothelial NO synthase), sirtuin 1 (SIRT1) and B lymphocytes in the pathogenesis of vascular ageing. Preventing vascular ageing may represent a key therapeutic strategy for cardiovascular disease. Our research aims to improve the understanding of the pathogenesis of vascular ageing and to identify potential therapeutic targets in reversing age-dependent arterial remodelling.
