Tissue injury in diabetes results from cell damage and death, impaired communication among cells, dysfunction of nerves and blood vessels, and detrimental responses to systemic signals, such as inflammation. The development of the clinical manifestations depends on tissue-specific responses to injury and impairments in repair and regenerative processes. The knowledge base of the pathologic process in different tissues ...more »
Normally, metabolic and ischemic insults stimulate repair and regeneration. In diabetes, however, these processes are impaired. Recent advances in cell reprogramming hold great promise for future cell replacement therapies. How are specific populations of stem/progenitor cells affected by diabetes? Are these abnormalities reversible through optimal diabetes treatment or therapies targeted to stem/progenitor cells? ...more »
The abundance of molecular pathways affected by diabetes presents the challenge of understanding complex interactions among the pathways, but also the opportunity of providing multiple and potentially complementary targets for drug development. How do the identified molecular pathways associated with diabetic nephropathy interact within each cell and does this vary for different cell types? Are there undiscovered molecular ...more »
The primary focus of the pathophysiology of diabetic renal disease has been on the glomerulus. Albuminuria has been shown to be a very sensitive biomarker of proximal tubule injury. Early changes in the proximal tubule may lead to secondary pathology which is typical for diabetic nephropathy. Thus the tubule may represent a therapeutic target for early diabetes.
