Periostin is a 90-kDa member of the fasciclin-containing family and functions as part of the extracellular matrix. Periostin is expressed in a variety of tissues and expression is increased in airway epithelial cells from asthmatic patients. Recent studies have implicated a role for periostin in allergic eosinophilic esophagitis. To further define a role for periostin in Th2-mediated inflammatory diseases such as asthma, we studied the development of allergic pulmonary inflammation in periostin-deficient mice. Sensitization and challenge of periostin-deficient mice with OVA resulted in increased peripheral Th2 responses compared with control mice. In the lungs, periostin deficiency resulted in increased airway resistance and significantly enhanced mucus production by goblet cells concomitant with increased expression of Gob5 and Muc5ac compared with wild type littermates. Periostin also inhibited the expression of Gob5, a putative calcium-activated chloride channel involved in the regulation of mucus production, in primary murine airway epithelial cells. Our studies suggest that periostin may be part of a negative-feedback loop regulating allergic inflammation that could be therapeutic in the treatment of atopic disease.
