Abstract Background C57BL 6 mice have attenuated allergic airway hyperresponsiveness AHR when compared with Balb c mice but the underlying mechanisms remain unclear. SP-D an innate immune molecule with potent immunosuppressive activities may have an important modulatory role in the allergic airway response and the consequent physiological changes. We hypothesized that an elevated SP-D production is associated with the impaired ability of C57BL 6 mice to develop allergic AHR. Methods SP-D mRNA and protein expression was investigated during development of allergic airway changes in a model of Aspergillus fumigatus Af -induced allergic inflammation. To study whether strain dependency of allergic AHR is associated with different levels of SP-D in the lung
