Implication

Animal model study reveals peak monocyte chemoattractant protein-1 expression in eosinophils during lung fibrosis, indicating their central role in mediating fibrotic pulmonary inflammation.

Key Points

To evaluate the cellular source, expression kinetics, and pathogenic role of monocyte chemoattractant protein-1 (MCP-1) in bleomycin-induced pulmonary fibrosis.
Induced lung fibrosis in male Fisher 344 rats via endotracheal bleomycin injection on day 0.
Harvested lung tissues across multiple time points up to day 21 post-injection for Northern hybridization, in situ hybridization, and histochemical/immunochemical analyses.
Lung MCP-1 mRNA expression elevated significantly starting on day 3, peaked on day 7, and declined toward baseline control levels after day 21.
In situ hybridization and chromotrope 2R staining identified infiltrating eosinophils within active fibrotic lesions as the primary cellular source of elevated MCP-1 mRNA and protein, with minor expression in reactive fibroblasts, mononuclear cells, and vascular cells.
