Abstract:

Both the macro- and microvascular complications adversely affect the life quality of patients with diabetes and have been the leading cause of mortality and morbidity in this population. With the advancement of technologies in biomedical research, we have gained a great deal of understanding of the mechanisms underlying these complications. While euglycemic control still remains the best strategy, it is often difficult to maintain at a level that can completely prevent the vascular complications. Therefore, it is necessary to use the processes leading to vascular dysfunction as a framework for designing novel molecular therapeutic targets. Several of the mechanisms by which diabetes induces vascular complications include increased flux through the polyol pathway, increased oxidative stress, activation of protein kinase C (PKC), vascular inflammation, and abnormal expression and actions of cytokines in the vasculature. Many of the therapies that target these pathways have proven successful in experimental models of diabetic complications. However, clinical studies using these treatments have mainly yielded inconclusive results. The pathogenesis of diabetic vascular complications and results from animal studies and key clinical studies are reviewed here.

More about this publication?

• Current Drug Targets aims to cover the latest and most outstanding developments on the medicinal chemistry and pharmacology of molecular drug targets e.g. disease specific proteins, receptors, enzymes, genes. Each issue of the journal will be devoted to a single timely topic, with series of in-depth reviews, written by leaders in the field, covering a range of current topics on drug targets. These issues will be organized and led by a guest editor who is a recognized expert in the overall topic. As the discovery, identification, characterisation and validation of novel human drug targets for drug discovery continues to grow; this journal will be essential reading for all pharmaceutical scientists involved in drug discovery and development.
