My current research interests include reversal of heart and kidney disease in diabetes: in particular, understanding the molecular mechanisms of diabetic complications in relation to impaired copper homeostasis in cardiomyocytes, VSMC and kidney cells, leading to heart failure, arteriosclerosis and kidney disease, through perturbations in cellular regulation of Cu homeostasis. Our aim is to better understand the metabolic basis of diabetic complications to improve our new therapeutic strategies.
Other research interests also include studies of molecular structure and function of amylin fibril aggregation and its relation to the islet beta-cell dysfunction in Type 2 Diabetes, with current emphasis on the analysis of small exocyclic cystine-knot peptide inhibitors for suppression of amyloid formation and the Fas-associated cell death pathway evoked by human amylin in cultured beta-cells and in a human amylin transgenic mouse model. This study has led to identification of molecules specifically targeting beta-cell apoptotic signalling, with beneficial effects on delay of diabetes onset and development, and prolonged survival. Our research is, in the long term, aimed towards the development of new drugs capable of suppressing beta-cell death in diabetes.
