Idiopathic pulmonary fibrosis is a very common interstitial lung disease derived
from chronic inflammatory insults, characterized by massive scar tissue
deposition that causes the progressive loss of lung function and subsequent death
for respiratory failure. Bleomycin is used as the standard agent to induce
experimental pulmonary fibrosis in animal models for the study of its
pathogenesis. However, to visualize the establishment of lung fibrosis after
treatment, the animal sacrifice is necessary. Thus, the aim of this study was to
avoid this limitation by using an innovative approach based on a double bleomycin
treatment protocol, along with the in vivo images analysis of bleomycin-treated
mice. A reporter gene construct, containing the luciferase open reading frame
under the matrix metalloproteinase-1 promoter control region, was tested on
double bleomycin-treated mice to investigate, in real time, the correlation
between bleomycin treatment, inflammation, tissue remodeling and fibrosis.
Bioluminescence emitted by the lungs of bleomycin-treated mice, corroborated by
fluorescent molecular tomography, successfully allowed real time monitoring of
fibrosis establishment. The reporter gene technology experienced in this work
could represent an advanced functional approach for real time non-invasive
assessment of disease evolution during therapy, in a reliable and translational
living animal model.
