What is mucociliary clearance?
Mucociliary clearance (MCC) is a defense mechanism of the respiratory system that removes mucus and pathogens from the airways.
Why use SPECT/CT imaging?
SPECT/CT imaging provides precise localization and quantification of mucociliary clearance in vivo.
What is the significance of using a mouse model?
Mice are commonly used in research due to their genetic similarity to humans and the ability to model various human diseases.
How is the radionuclide administered?
The radionuclide is administered via intubation, allowing the mouse to inhale it into the lungs.
What types of analyses were performed on the imaging data?
SPECT and CT images were co-localized, analyzed for mucociliary clearance, and statistically validated.
What potential applications does this protocol have?
The protocol can be applied to assess drug effects on airway clearance in various disease models.
