Targeting CD39 Toward Activated Platelets Reduces Systemic Inflammation and Improves Survival in Sepsis: A Preclinical Pilot Study

Abstract

Objectives: Sepsis is associated with a systemic inflammatory reaction, which can result in a life-endangering organ dysfunction. Pro-inflammatory responses during sepsis are characterized by increased activation of leukocytes and platelets, formation of platelet-neutrophil aggregates, and cytokine production. Sequestration of platelet-neutrophil aggregates in the microvasculature contributes to tissue damage during sepsis. At present no effective therapeutic strategy to ameliorate these events is available. In this preclinical pilot study, a novel anti-inflammatory approach was evaluated, which targets nucleoside triphosphate hydrolase activity toward activated platelets via a recombinant f..
