Abstract:
:Immunofluorescent and immunoelectron-microscopic staining methods were utilized to investigate the localization of Ia antigens in murine keratinizing epithelia. Approximately 3-5% of epidermal cells were shown to be Ia positive. Only dendritic Langerhans cells in the interfollicular epidermis and outer root sheaths were found to express Ia antigens. These Ia determinants were shown to be controlled by both theI- A andI- EC subregions of theH-2 complex. The results were confirmed by identifying positively stained cells containing Langerhans cell granules at the ultrastructural level. No staining was noted on the surface of keratinocytes, melanocytes, or immigrant lymphocytes. The results presented are in close agreement with those previously reported for Ia-bearing Langerhans cells in human and guinea pig epidermis.
