Level of neutrophil chemotactic factor CINC/gro, a member of the interleukin-8 family, associated with lipopolysaccharide-induced inflammation in rats.

Rat cytokine-induced neutrophil chemoattractant (CINC), which is a counterpart of human gro and belongs to the interleukin-8 family, has been quantified by a new sandwich enzyme-linked immunosorbent assay. Administration of lipopolysaccharide (LPS) into an air pouch performed by subcutaneous injection of air caused inflammation and severe neutrophil infiltration. After the LPS injection, changes in the concentration of CINC/gro, chemotactic activity, and the number of neutrophils in the air pouch exudate were determined. The chemotactic activity of neutrophils was augmented before practical neutrophil infiltration. More than half of the chemotactic activity was neutralized by the antisera. The time kinetics of the level of CINC/gro coincided with the changes in chemotactic activity. The maximal level of rat CINC/gro was 85 ng/ml, which is sufficient to cause neutrophil migration in vitro and in vivo as described previously. These data suggest that rat CINC/gro is a functional chemoattractant for neutrophils in LPS-induced inflammation in rats
