Surfactant Proteins A, B, C and D in the Human Nasal Airway: Associated with Mucosal Glands and Ciliated Epithelium but Absent in Fluid-Phase Secretions and Mucus

Conclusion: SP-A, -B, -C and -D exert their protective effect in the ductal epithelium of the submucosal glands rather than in nasal secretions and mucus. Further studies are required to clarify the functions of these proteins in nasal secretory pathways for understanding upper airway diseases.ORL 2014;76:288-301
