Abstract Background Respiratory viral infections are characterized by the infiltration of leukocytes including activated neutrophils into the lung that can lead to sustained lung injury and potentially contribute to chronic lung disease. Specific mechanisms recruiting neutrophils to the lung during virus-induced lung inflammation and injury have not been fully elucidated. Since CXCL1 and CXCL2 3 acting through CXCR2 are potent neutrophil chemoattractants we investigated their role in dsRNA-induced lung injury where dsRNA Poly IC is a well-described synthetic agent mimicking acute viral infection. Methods We used 6-8 week old
