title: Effects of fexofenadine on T-cell function in a murine model of allergen-induced airway inflammation and hyperresponsiveness.
abstract: There is renewed interest in antihistamines for the treatment of allergic asthma. A growing body of literature has shown that the newer compounds can affect inflammatory cell accumulation and cytokine/chemokine production. In a murine model of allergen-induced airway inflammation and hyperresponsiveness, the ability of fexofenadine to affect these outcomes was tested in a primary sensitization and challenge model and after treatment of donor mice before the adoptive transfer of T cells into recipients receiving limited allergen exposure. Mice were sensitized and challenged with allergen (ovalbumin). Airway function after inhaled methacholine was monitored in parallel to the assessment of tissue and airway inflammation and cytokine production. In further experiments, lung T lymphocytes from sensitized/challenged donor mice were transferred into naive recipients before limited airway challenge with the allergen. Administration of fexofenadine before challenge but after sensitization was effective in preventing tissue eosinophilia and airway hyperresponsiveness. Moreover, the treatment of donor mice with fexofenadine before transfer of lung T cells effectively prevented airway hyperresponsiveness and eosinophilia in naive mice exposed to limited airway challenge. These data therefore support the potential for fexofenadine in the treatment of allergen-induced airway hyperresponsiveness and inflammation.
