Abstract

Vascular disease is a major component of the complications associated with diabetes. The pathology involves hypertrophy and proliferation of vascular smooth muscle cells and the production and modification of extracellular matrix. The sodium/hydrogen exchanger has been widely implicated in the growth of multiple cell types, including vascular smooth muscle. Increases in sodium/hydrogen exchange activity serve as an effector or at least as an indicator of vascular activation. This article is concerned with the role of the biochemical abnormalities of diabetes exerting their pathological effects on vascular smooth muscle cells via altering sodium/hydrogen exchange activity.
