| Research Abstract |
Neutrophil chemotaxis was reduced in septic patients and poorly controlled diabetic patients. Neutrophil bactericidal ability in the patients with liver cirrhosis, SLE, AIDS, myeloma, severe burn and elderly persons was significantly lower than that of healthy controls. Expression levels of neutrophil membrane antigens, CD14 and TLR-4 were higher in patients with sepsis ; however, the expression levels of CD11b and CD16 were lower. The gene expression of TREM-1 in neutrophils associated with the severity of sepsis. Analysis of neutrophil functions using these assays may be available as the sensitive and reliable immuno-monitoring tools for determining the capacity of host defense against bacterial infections in compromised hosts.
