FZ parenchymGuinea pig model of acute LPS exposure


  • Neutrophilic inflammation in the bronchoalveolar lavage fluid

We can test the effectiveness of your compound against this neutrophilic inflammation. We have previously demonstrated efficacy of anticholinergics and β2 agonists in this model.

CollagenGuinea pig model of chronic LPS exposure


  • Twice weekly LPS challenges for 12 weeks,
  • Tissue neutrophilia and cytokine production,
  • Collagen deposition around the small airways,
  • Mucus gland hypertrophy, goblet cell hyperplasia,
  • Right ventricle remodeling.

We have previously shown efficacy of anticholinergics and GSK-3 inhibitors in this model.
