Abstract Background The pulmonary surfactant protein SP -A has potent immunomodulatory activities but its role and regulation during allergic airway inflammation is unknown. Methods We studied changes in SP-A expression in the bronchoalveolar lavage BAL using a murine model of single Aspergillus fumigatus Af challenge of sensitized animals. Results SP-A protein levels in the BAL fluid showed a rapid transient decline that reached the lowest values 25 of controls 12 h after intranasal Af provocation of sensitized mice. Decrease of SP-A was .
