Figure 1

Surfactant protein D expression in human airway sections. SP-D expression was examined in sections of airways from non-asthmatic and asthmatic donors via immunohistochemistry, where pink was indicative of positivity [A]. Fraction of total epithelial area positive was quantified using colour segmentation in ImagePro Plus. Expression of SP-D in the airway epithelia of asthmatic donors was significantly higher compared to non-asthmatic donors (n = 11, t-test p = 0.004) [B].
