ABSTRACT
Neutrophils, immune cells crucial for protecting against invading pathogens, are important in sepsis. Neutrophil migration is regulated by chemokine receptors and their cognate ligands. Our previous study investigated the effect of nbutanol extract from Folium isatidis on lipopolysaccharide (LPS)induced septic shock. The present study stimulated neutrophils with LPS to explore the influence of LPS on cell. Neutrophils were then pretreated with nbutanol extract from Folium isatidis followed by LPS to examine the effect of this extract on neutrophil chemotaxis. The results showed that LPS decreased the expression levels of CXCchemokine receptor (CXCR)1, CXCR2 and Lselectin (CD62L), and increased the expression of interleukin8 (IL8) by neutrophils. The addition of nbutanol extract from Folium isatidis inhibited this LPSinduced downregulation of CXCR1, CXCR2 and CD62L, and decreased the expression of IL8 on neutrophils. In addition, nbutanol extract promoted myeloperoxidase activity in neutrophils. Taken together, LPS downregulated the expression of chemokine receptors, leading to the failure of neutrophils to migrate to sites of infection. The addition of nbutanol extract, which promoted the ability of neutrophils to migrate, is a natural product and potential therapeutic agent with which to target neutrophil chemotaxis during LPS stimulation.
