Establishment of a chronic aspiration pneumonia mouse model using oropharyngeal aspiration of food suspension

Animal Models and Experimental Medicine, EarlyView.
Four aspiration methods (UV, IN, IT, and OA) were compared, and OA was identified as the most effective delivery technique. A chronic aspiration pneumonia model was then established through repeated OA of food suspension or gastric contents. Integrated analyses, including micro‐CT, histopathology, cytokine profiling, and RNA sequencing, revealed ...
