Potential applications of anti-keratin antibodies in oral diagnosis.
Recent progress in understanding the biology of keratins together with the development of monoclonal antibodies to individual keratin proteins provide the foundation for studying keratin expression in normal and pathological oral epithelia. Areas of oral pathology in which the examination of epithelial keratin profiles may yield information of potential diagnostic value are discussed. Examples of altered keratin expression in epithelial dysplasia, oral cancer and odontogenic cysts and tumours are presented. Immunocytochemical demonstration of individual keratins can clarify the composition of complex epithelia and may help to establish epithelial lineage or indicate progression changes in tumours. Some problems in the application and interpretation of keratin immunocytochemistry are also considered.
