Mechanistic Modelling of the Linkage Between Proximal Tubule Cell Sublethal Injury and Tubular Sodium Reabsorption Impairment

Introduction

  • Sublethal renal epithelial cell injury, a key manifestation of drug-induced acute kidney injury (AKI), is characterized by loss of brush border and cellular polarity of proximal tubular cells (PTCs).
  • The key cellular alterations caused by sublethal injury involve impaired energetics and associated disruptions in cytoskeletal structure and sodium transporters activity.
  • Our objective is to develop a mechanistic model relating cellular injury of AKI with renal tubular dysfunction needed to represent the complexity of renal pathophysiology.
