ATP as a death factor: purinergic signaling in renal epithelial-fibroblast cross talk

Abstract

peritubular fibroblasts are a major fraction of interstitial cells in the kidney that produce erythropoietin. In an issue of the American Journal of Physiology-Renal Physiology , Ponnusamy and colleagues ([14][1]) have explored the mechanism linking renal tubular epithelial cell death and injury to
