Dipeptidase-1 governs renal inflammation during ischemia reperfusion injury

Importantly, the study also confirmed the mechanism of action of two DPEP-1 inhibitors, the LSALT peptide (Metablok) and cilastatin that effectively protected the kidney during ischemia reperfusion injury. Both the LSALT peptide and cilastatin are protected by composition and method of use patents for AKI respectively and held by Arch Biopartners.

Highlights
  • Dipeptidase 1 (DPEP1) serves as a vascular adhesion molecule in lungs and liver
  • DPEP1 acts as a physical adhesion receptor independent of its dipeptidase activity
  • Targeting DPEP1 reduces mortality in murine models of sepsis
Abstract

A hallmark feature of inflammation is the orchestrated recruitment ...

Abstract

Radiographic contrast agents cause acute kidney injury (AKI), yet the underlying pathogenesis is poorly understood. Nod-like receptor pyrin containing 3–deficient (Nlrp3-deficient) mice displayed reduced epithelial cell injury and inflammation in the kidney in a model of contrast-induced AKI ...
