UNASSIGNED: Aims: To investigate the presence of @entity68583 in nasal airways and to determine whether the proteins exert their main functions in nasal secretions or in the deeper layers of the nasal mucosa. Methods: Volunteers were recruited from the Department of ENT Head and Neck Surgery, Odense University Hospital, Denmark. The study included 39 subjects. Nasal mucosal biopsies were analyzed by immunohistochemistry, and bronchoalveolar and nasal lavages, nasal brush biopsies and nasal mucus were analyzed for @entity3231 , -B, -C and -D by @entity214 -PAGE and Western blotting. The presence of @entity3231 and @entity9914 in the first three samplings were also analyzed by enzyme-linked immunosorbent assay. Results: In nasal mucosal biopsies, @entity3231 , -B, -C and -D were all demonstrated in the serous acini of the submucosal glands and in the surface epithelium. @entity9914 was detected in nasal brush biopsies, whereas the other SPs were absent. Moreover, @entity3231 , -B, -C and -D were absent in nasal lavage and mucus. Conclusion: @entity3231 , -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.    2014 S. Karger AG, Basel.
