Matrix Metalloproteinase-9 and Neutrophil Extracellular Traps in Human and Mouse Liver Ischemia and Reperfusion Injury
S. Duarte, A. Zarrinpar, R. W. Busuttil, A. J. Coito
Dumont-UCLA Transplant Center, Los Angeles, CA
*Purpose: Neutrophils are key mediators of ischemia/reperfusion injury (IRI) in orthotopic liver transplantation (OLT). Once activated, they release nuclear DNA web-like structures called neutrophil extracellular…
