Abstract

Ia-bearing dendritic cells (DC) are a class of bone marrow-derived antigen-presenting cells that appear to possess an increased capacity to stimulate resting T lymphocytes. DC from different tissues share several morphologic, phenotypic and functional attributes. For example, freshly isolated DC from spleen resemble phenotypically and functionally freshly isolated Langerhans cells (LC) from epidermis; in addition, during short-term culture both DC and LC undergo several parallel changes including modifications affecting phenotype, capacity to present protein antigens, and ability to route surface Ia molecules into intracellular acidic compartments (J Immunol 1990: 145: 2820-2826). In the present study we show, using immunoelectron microscopy with anti-Ia and anti-33D1 monoclonal antibodies, freshly isolated DC in suspension to have a smooth cell surface with few and short cytoplasmic projections. By contrast, cultured DC display conspicuous bulbous cytoplasmic protrusions. In addition, spleen DC following culture for 24-48 hours exhibit an increased ability to stimulated allogeneic T lymphocytes in the primary mixed leukocyte reaction. These changes, similar to those described for freshly isolated and cultured LC respectively, further substantiate the close relationship between DC and LC.
