Our primary goal at the Glomerular Disease Therapeutics Laboratory (GDTL) is to develop novel mechanism based therapy for proteinuria and chronic kidney disease related to glomerular disorders. We use existing animal models, and develop new mechanistically relevant rat models of glomerular disease to study genes and proteins that have potential in future glomerular therapeutics. We also conduct a variety of cell biology, proteomic, molecular biology and imaging studies to rigorously test our hypothesis and develop new agents for treatment of human glomerular disease. Novel therapeutic strategies in advanced stages of development include the use of compounds that alter sialylation in vivo, and various forms of recombinant Angiopoietin-like-4 in the treatment of some forms of nephrotic syndrome (see patents below). We are actively engaged in identifying a circulating glomerulophilic proteome (CGP) that modulates human glomerular disease.
Location: We are physically located on the 6th floor of Tinsley Harrison Tower (rooms 612, 611A, 611B and 611N) in the Division of Nephrology at the University of Alabama at Birmingham.
Patented therapeutic strategies in accelerated development
1) The use of sialic acid precursors in the treatment of glomerular disease and nephrotic syndrome. U. S. patent and PCT have been filed. We welcome communication from parties interested in the licensing or commercialization of this patent.
2) The use of recombinant Angiopoietin-like-4 and its mutants in the treatment of proteinuria, glomerular disease and nephrotic syndrome. In addition to the original PCT, several other patent applications have been filed. We welcome communication from parties interested in the licensing or commercialization of this patent.
