Target
Surfactant protein D (SP-D) is synthesized and secreted by lung epithelial cells. It belongs to group III ofthe family of C-type lectins and members of this group has overall structure consisting of multipleglobular "head" regions linked by triple-helical, collagen-like, strands. This group also includes SP-A andthe serum proteins mannan-binding protein, conglutinin and collectin-43, all of which have been shownto bind to the C1q receptor found on a wide variety of cells. Both SP-D and SP-A have been shown toenhance oxygen radical production by alveolar macrophages. The serum concentration is 88 ng/ml inhealthy individuals. (1)
