Animal Models of Cigarette Smoke-Induced COPD*

Joanne L. Wright, MD and Andrew Churg, MD

Objectives: To review the animal models of COPD, and to compare these data to those found in humans.

Results: Smoke-induced animal models can produce emphysema, although the lesions are not generally close mimics of human emphysema, as well as increases in mucous-secreting cells and vascular changes including pulmonary hypertension. There is considerable species-to-species variation in the degree and/or presence of these different abnormalities, so that care has to be used in selecting a species to study. Remarkably little information is available about the biochemical and molecular changes induced by cigarette smoke in animal models.

Conclusions: Great insights into the pathology of chronic obstructive lung disease have been made using various animal models.

Key Words: animal models • cigarette smoke • emphysema • inflammation
