Immunohistochemical characterization and distribution of Langerhans cells in normal epithelium of the uterine cervix.
Langerhans cells (LCs) were shown up in normal cervical tissue obtained from 32 women whose age ranged from 25 to 68 years, using immunohistological methods. LCs were detected in metaplastic and native squamous epithelium of the cervix; they were positive to Dako-LC and OKDR antibodies and those located in the basal-suprabasal epithelial layers were also OKT6-positive. The density of the LCs was higher during the proliferative phase of the menstrual cycle. The investigation into the lymphocytes present in the stroma and in the squamous epithelium showed a population of T-lymphocytes identified as predominantly T-cytotoxic/suppressor cells, sometimes in contact with LCs. The significance of these findings is discussed.
