Dendritic cells (DCs) are the most potent professional antigen-presenting cells, and capable of stimulating naïve T cells and driving primary immune responses. DCs are poised to capture antigen, migrate to draining lymphoid organs, and after a process of maturation, select antigen-specific lymphocytes to which they present the processed antigen, thereby inducing immune responses. The development of protocols for the ex vivo generation of DCs may provide a rationale for designing and developing DC-based vaccination for the treatment of tumors. There are now several strategies being applied to upload antigens to DCs and manipulate DC vaccines. DC vaccines are able to induce therapeutic and protective antitumor immunity. Numerous studies indicated that hepatocellular carcinoma (HCC) immunotherapies utilizing DC-presenting tumor-associated antigens could stimulate an antitumour T cell response leading to clinical benefit without any significant toxicity. DC-based tumor vaccines have become a novel immunoadjuvant therapy for HCC.
