Generation of Tumor Targeted Dendritic Cell Vaccines with Improved Immunogenic and Migratory Phenotype.

Journal Article (Journal Article)

Our group has employed methodologies for effective ex vivo generation of dendritic cell (DC) vaccines for patients with primary malignant brain tumors. In order to reliably produce the most potent, most representational vaccinated DC that will engender an antitumor response requires the ability to orchestrate multiple methodologies that address antigen cross-presentation, T-cell costimulation and polarization, and migratory capacity. In this chapter, we describe a novel method for augmenting the immunogenicity and migratory potential of DCs for their use as vaccines. We have elucidated methodologies to avoid the phenomenon known as immunodominance in generating cancer vaccines. We have found that culturing DC progenitors in serum-free conditions for the duration of the differentiation protocol results in a more homogeneously mature population of DCs that exhibit enhanced immunogenicity compared to DCs generated in serum-containing culture conditions. Furthermore, we demonstrate our method for generating high mobility DCs that readily migrate toward lymphoid organ chemoattractants using CCL3 protein. The combination of these two approaches represents a facile and clinically tractable methodology for generating highly mature DCs with excellent migratory capacity.
