ABSTRACT
Dendritic cells (DCs) are the most powerful and professional antigen-presenting cells (APCs) known at present. They play vital roles in the initiation and regulation of immune responses in body. Therefore, DC-based vaccine delivery system has gradually become a hotspot of basic scientific research and clinical treatment. DCs can be loaded with whole-cell antigens, nucleic acids, peptides, proteins (such as neoantigens) and nanoparticles to induce specific cellular immune responses and humoral immune responses after antigen processing, presentation and targeting delivery in vivo for the prevention and treatment of various diseases including cancers and microorganism infections. Vaccine-based on this technique is called dendritic cell (DC) vaccines. Great process in DC vaccines has been achieved in recent years. Therefore, we reviewed the characteristics of DC, types of DC vaccines and their clinical research progress in this paper.
