While other reports have previously shown increased levels of the major neutrophil chemoattractant KC in the BAL of βENaC-Tg mice at earlier time points [19, 21], here we report increased airway concentrations of MIP-1α, MIP-1β, MCP-1, IL-5, IL-6, and G-CSF in this CF mouse model. Here, IL6 is linked to cystic fibrosis.
