Expression of MUC5AC in unstained lung sections (A): (a) untreated (OVA-challenged), (b) theophylline, (c) theophylline plus pure chitosan nanoparticles, (d) theophylline plus TCNs (top panel: nuclei stained with DAPI, bottom panel: FITC-labeled muc5AC) and semiquantitative analysis of muc5AC in unstained lung sections (B). The results of a representative experiment of two performed is shown. **p < 0.01, *p < 0.05 compared with TPL group.
