Studies performed in the Goligorsky laboratory in the last five years have established a) the role of premature cell senescence in endothelial dysfunction; b) contribution of endothelial progenitor cells (EPC) to rescuing the kidney from ischemia/reperfusion injury; c) the pathways of EPC mobilization and engraftment post-ischemia; d) the role of renal resident mesenchymal stem cells in renoprotection; e) the role of glial cell-derived neurotrophic factor in stimulating migration and antiapoptotic properties of mesenchymal stem cells; f) proteomic analysis of the urine in recipients of kidney transplant. Currently, Dr. Goligorsky is exploring the mechanism whereby alarm signaling, an innate immune response, mobilizes stem cells to the post-ischemic tissue/organ, the mechanisms of premature senescense of stem cells, and the proteomic phenotype of dysfunctional endothethial cells and their progenitors.
