It is synthesized primarily in the lung by alveolar type II cells and unciliated bronchial epithelial cells. In addition, SP-D is produced by epithelial cells of the gastrointestinal tract and exocrine glands. SP-D binds to patterns of neutral sugars on micro-organisms to mediate direct opsonization and phagocytosis and is an important component of the innate immune system.
