A recent review by Sørensen et al (24) describes the role of SP-D in lung function and its potential role in a broad variety of human diseases, including chronic inflammatory conditions such as chronic obstructive pulmonary disease (COPD) and asthma, illustrating the broad role that this molecule plays in the innate immune system and human biology in general. The gene discussed is SFTPD; the disease is chronic obstructive pulmonary disease.
