CSF3 and infection: nCD64 is an inflammatory cytokine expressed by neutrophils after exposure to a large number of inflammatory cytokines (e.g., lipopolysaccharide, G-CSF, etc.), and although it has been shown in the literature to have a predictive role in infections in patients with leukemia, the changes of nCD64 in granulocyte-deficient patients still need to be further investigated.
