Airway inflammation and remodeling are primary characteristics of long-standing asthma. A balance between the TH1/TH2 cytokines regulates the accumulation and activation of inflammatory cells, including mast cells and eosinophils. Recently, we demonstrated that pUMVC3-hFLex, an active plasmid, mammalian expression vector for the secretion of Flt3-L, reversed established airway hyperresponsiveness (AHR) in a murine model of acute allergic airway inflammation. The present experiments were undertaken to examine the effect of pUMVC3-hFLex in a chronic model of allergic airway inflammation that was established in Balb/c mice by sensitization and challenge with ovalbumin (OVA). pUMVC3-hFLex or the control plasmid, pUMVC3, were administered by injection into the muscle interior tibialis. Treatment with pUMVC3-hFLex completely reversed established AHR (p
