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 »
Non-mammalian model organisms have been underutilized to understand diabetic nephropathy pathogenesis. These simple model organism systems that permit ease of genetic manipulation, rapid throughput and precise measurement of phenotypes. Work published earlier this year (PNAS 107: 775, 2010) demonstrated that type 2 DM risk loci could be characterized in zebrafish. Interestingly, this study demonstrated this study shows ...more »
What are the regulators of glomerular basement membranes? Can we target glomerular endothelium and podocytes to restore normal barrier components and functions?
