The Role of Neutrophil cd64 Expression in Distinguishing Acute Inflammatory Autoimmune Disease from Systemic Infections

cd64 or fcyri is transmembrane glycoprotein-globulin gene superfamily, it is upregulated on neutrophils as aphysiological response to microbial wall, complement split products and some cytokines. stimulation of neutrophils through the high affinity receptor (fcyri) or cd64) plays an imprtant role in the enhancement of neutrophil phagocytosis and intracellular killing of bacteria.
