Based on their tissue localization, ultrastructural features, and expression of surface markers, two subpopulations of cells were isolated, CD45(+) interdigitating dendritic cells (IDCs) and CD45(-) follicular dendritic cells (FDCs)." "IDCs expressed MHC class I, MHC class II, and selectin, induced the proliferation of allogeneic naive CD4(+) T cells, and increased the secretion of IFN-gamma by autologous T cells. FDCs expressed surface IgG, IgM, ICAM-1, and...
