Abstract

A monoclonal antibody was generated by immunizing rats with Langerhans cell (LC)-enriched epidermal cells obtained from BALB/c mouse earskin after epicutaneous application of the contact sensitizer 2,4-dinitrofluorobenzene (DNFB). The antibody 4F7 detects in normal mouse skin, few dermal cells showing the morphologic, phenotypic, and functional properties of accessory dendritic cells, but lacking Birbeck granules. The capacity to stimulate allogenic T cells in the mixed leucocyte reaction resembles that of freshly isolated LCs. After DNFB application, an increased number of 4F7+ dendritic cells are found in the dermis and, in addition, some labeled dendritic cells occur in the epidermis. Some of the latter cells exhibit cytoplasmic Birbeck granules. Remarkably, there is no increase of the 4F7+ cells in the regional lymph nodes after DNFB treatment. These data suggest that the 4F7 antibody labels distinct dendritic cells of the mouse skin that are involved in the mediation of contact sensitization and probably represent immature LCs.
