dc.description.abstractThe fundamental role of dendritic cells (DC) in initiating and directing the primary immune response is well established. Furthermore, it is now accepted that DC may be useful in new vaccination strategies for preventing certain malignant and infectious diseases. As blood DC (BDC) physiology differs from that of the DC homologues generated in vitro from monocyte precursors, it is becoming more relevant to consider BDC for therapeutic interventions. Until recently, protocols for the isolation of BDC were laborious and inefficient; therefore, their use for investigative cancer immunotherapy is not widespread. In this study, we carefully documented BDC counts, yields and subsets during apheresis (Cobe Spectra), the initial and essential procedure in creating a BDC isolation platform for cancer immunotherapy. We established that an automated software package (Version 6.0 AutoPBPC) provides an operator-independent reliable source of mononuclear cells (MNC) for BDC preparation. Further, we observed that BDC might be recovered in high yields, often greater than 100% relative to the number of circulating BDC predicted by blood volume. An average of 66 million (range, 17–179) BDC per 10-l procedure were obtained, largely satisfying the needs for immunization. Higher yields were possible on total processed blood volumes of 15 l. BDC were not activated by the isolation procedure and, more importantly, both BDC subsets (CD11c+CD123low and CD11cCD123high) were equally represented. Finally, we established that the apheresis product could be used for antibody-based BDC immunoselection and demonstrated that fully functional BDC can be obtained by this procedure.
