Potential New Treatment For Lung Scarring Caused By Chronic Asthma

Summary:
Chronic asthma often results in scarring of the lung airways (airway fibrosis) and this can cause airway obstruction. The soluble factor TGF-beta-1, produced by inflammatory cells known as eosinophils, drives the processes that cause airway fibrosis. New data, generated in rodents, has now led to the suggestion that targeting the protein PIN1 might provide a new approach to limiting airway fibrosis driven by the production of TGF-beta-1 by activated eosinophils in individuals with chronic asthma.

The soluble factor TGF-beta-1, produced by inflammatory cells known as eosinophils, has been shown to drive the processes that result in airway fibrosis, notably fibroblast proliferation and extracellular matrix deposition.

Now, James Malter and colleagues at the University of Wisconsin School of Medicine and Public Health, Madison, have generated new data in rodents that has led them to suggest that targeting the protein PIN1 might provide a new approach to limiting airway fibrosis driven by the production of TGF-beta-1 by activated eosinophils in individuals with chronic asthma.

These data include the following two observations: first, that pharmacologic blockade of PIN1 in a rat model of chronic asthma reduced TGF-beta-1 expression by activated eosinophils and airway fibrosis; and second, that mice lacking PIN1 showed reduced airway fibrosis when chronically exposed to an allergen.
