Abstract Background Ozone O3 a common air pollutant induces exacerbation of asthma and chronic obstructive pulmonary disease. Pulmonary surfactant protein SP -D modulates immune and inflammatory responses in the lung. We have shown previously that SP-D plays a protective role in a mouse model of allergic airway inflammation. Here we studied the role and regulation of SP-D in O3-induced inflammatory changes in the lung. Methods To evaluate the effects of O3 exposure in mouse strains with genetically different expression levels of SP-D we exposed Balb c C57BL 6 and SP-D knockout mice to O3 or air. BAL cellular and cytokine content and SP-D levels were evaluated and compared between
