Antibiotic-resistant superbug bacteria represent a global health problem with no imminent solutions. Here we demonstrate that the combination (termed AB569) of acidified nitrite (A-NO2−) and Na2-EDTA (disodium ethylenediaminetetraacetic acid) inhibited all Gram-negative and Gram-positive bacteria tested. AB569 was also efficacious at killing the model organism Pseudomonas aeruginosa in biofilms and in ...

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 ...
