Relationship between inflammatory cell infiltration and gene expression of each 5 chemokines in exposed lung. (A) CXCL5 mRNA expression, (C) CCL2 mRNA expression, (E) CCL7 mRNA expression, (G) CXCL10 mRNA expression, (I) CXCL11 mRNA expression at 1 week after the instillation versus score of inflammatory cell infiltration and (B) CXCL5 mRNA expression, (D) CCL2 mRNA expression, (F) CCL7 mRNA expression, (H) CXCL10 mRNA expression, (J) CXCL11 mRNA expression at 1 month after the instillation versus score of inflammatory cell infiltration. There was relatively good correlation between inflammatory cell infiltration in lung tissues and CXCL5, CCL2, and CCL7 at one week and one month after intratracheal instillation.
