The recent therapeutic benefit in severe asthmatics provided by bronchial thermoplasty, a therapy that attenuates bronchoconstriction via reduction of airway smooth muscle (ASM) mass, has strongly supported the notion that ASM is a key player in the pathogenesis of asthma. ASM could also participate in the progression of asthma by secreting pro-inflammatory mediators reported both in cultured cells and in bronchial biopsies. My research interest includes airway smooth muscle biology, glucocorticoid signaling, and glucocorticoid resistance. Current research efforts are focused in four major areas:
