As professional antigen presenting cells, dendritic cells(DCs) greatly determine the quality of the innate and adaptive immunities. Therefore, DC-based immunotherapy has been one of the hotspots in cancer immunotherapy in recent years. Although this unique therapeutic strategy has been approved by U.S. Food and Drug Administration for prostate cancer treatment, the efficacy of DC-based immunotherapy remains to be further improved. Moreover, it is still not completely clear about the immunological basis of DCs, which is another hurdle for the progress of DC-based immunotherapy. Due to their unique physicochemical properties, nanomaterials have shown potentials in addressing these above mentioned problems and have provided important guidelines for optimizing DC-based immunotherapy. However, it is still at the starting stage for this emerging field and there are many critical questions in the rational design of this therapeutic strategy to be answered. Therefore, it is greatly necessary to review and analyze recent progresses in this field. In this review, we mainly focus on the development of various types nanoparticles for DC-based immunotherapy. The existed challenges in this field are also discussed. As professional antigen presenting cells, dendritic cells (DCs) greatly determine the quality of the innate and adaptive immunities.
