✦ Synopsis

The cytokertatins in respiratory epithelial cells (REC) of human nasal polyps and turbinates were analyzed by immunohistochemistry. Cytokeratin 19 (CK19) was present in all REC, CKS and 14 were expressed primarily in basal cells, and CK7, 8, and 18 were found in suprabasal cells. Differences in cytoplasmic locations were also apparent among the individual cytokeratins. CK13 was not detected in any REC of these tissues. The results indicate the profile of cytokeratins in REC of human nasal polyps and turbinates is essentially identical to that of REC in the more distal respiratory tract.

## Abstract During normal keratinocyte differentiation, a coordinated expression of many cytoskeletal and regulatory proteins occurs. Several studies suggest that expression of some of these proteins is altered in epithelium infected by the human papillomavirus (HPV). To examine protein expression,
