Review of the Literature: Sepsis and Neutrophil Cd64

Published on: 2017-04-05


Sepsis is a systemic inflammatory response against suspected or documented infection. In an infectious process, inflammation is triggered activating leukocytes, mainly neutrophils. CD64 is a surface antigen weakly expressed on non-activated mature neutrophils. When neutrophil CD64 is strongly expressed on neutrophils, it means neutrophils were activated, thus suggesting the presence of bacterial infection or acute fungal infection. A large number of biological substances has been investigated as candidate biomarkers and/or mediators of sepsis. Recent studies have focused on the investigation of neutrophil CD64 as a possible biomarker for the diagnosis of sepsis.
