PG - e53824 LID - 10.3791/53824 [doi] LID - 53824 AB - Dendritic cells (DCs) are professional antigen-presenting cells primarily responsible for acquiring, processing and presenting antigens on antigen presenting molecules to initiate T-cell-mediated immunity. Dendritic cells can be separated into several phenotypically and functionally heterogeneous subsets. Three important subsets of splenic dendritic cells are plasmacytoid, CD8alpha(Pos) and CD8alpha(Neg) cells. The plasmacytoid DCs are natural producers of type I interferon and are important for anti-viral T cell immunity. The CD8alpha(Neg) DC subset is specialized for MHC class II antigen presentation and is centrally involved in priming CD4 T cells. The CD8alpha(Pos) DCs are primarily responsible for cross-presentation of exogenous antigens and CD8 T cell priming. The CD8alpha(Pos) DCs have been demonstrated to be most efficient at the presentation of glycolipid antigens by CD1d molecules to a specialized T cell population known as invariant natural killer T (iNKT) cells. Administration of Flt-3 ligand increases the frequency of migration of dendritic cell progenitors from bone marrow, ultimately resulting in expansion of dendritic cells in peripheral lymphoid organs in murine models. We have adapted this model to purify large numbers of functional dendritic cells for use in cell transfer experiments to compare in vivo proficiency of different DC subsets.
