Study of the pathogenesis and reversibility of airway damage and repair (remodeling) during chronic mucosal immune response to environmental allergens in a large animal model of asthma.
EF 2009-10
Résumé
In human asthma, repeated exposure to environmental allergens leads to persistent inflammation and damage (remodeling)
of the lungs, and a progressive loss of airway function. Our proposed studies aim to determine 1) if the lesions present in the
lung tissue of asthmatic individuals are reversible by decreasing the level of allergen exposure or by the administration of
corticosteroids and antileukotrienes, two common therapeutics for this condition, and 2) if so, identify the cells and the
mediators responsible for these changes. These results will provide insight to the relationship between inflammation,
remodeling and airway function and may lead to the discovery of novel anti-remodeling therapy. These studies are
conducted in equine heaves, a natural disease of horses that shares many similarities with human asthma.
