The Dendritic Cell Exclusion Kit is a combination of monoclonal antibodies directed against T-lymphocytes (CD3), B-Lymphocytes (CD19), natural killer (CD56) and monocytes (CD14) all conjugated with FITC. Peripheral blood dendritic cells can be distinguished from other leucocytes by their characteristic lack of staining with this combination (1). Dendritic cells constitute a heterogeneous group of cells which play a crucial role in the immune system since they represent the most potent professional antigen-presenting cells for the initiation of immune responses. This is related to their widespread localization in all sites of antigen entry, their high expression of immunomodulatory molecules necessary for T cell activation, and their production of cytokines. In recent years there has been an increasingly high interest on the study of dendritic cells, particularly due to their possible application in immunotherapy. Accordingly, the ability of dendritic cells to stimulate primary T lymphocyte and T cell-dependent immune responses may provide opportunities for therapeutic intervention in bone marrow and solid organ transplantation, as well as in autoinmune diseases. In addition, protocols for clinical immunotherapy programmes, targeted on malignant cell antigens or infectious agents, have been designed to exploit dendritic cells as a natural adjuvant for optimal therapeutic vaccination. Dendritic cells can be identified in human peripheral blood as the fraction of nucleated cells which do not show reactivity for CD3, CD19, CD56 and CD14 antigens and which at the same time are positive for HLA-DR. At flow cytometry these cells display a typical light scatter pattern, with FSC/SSC intermediate values between lymphocytes and monocytes.
