Special Issue Information

Dear Colleagues,

Dendritic cells (DCs) are the most effective antigen-presenting cells and are capable of efficiently cross-presenting tumor-associated antigens and priming tumor antigen-specific CD8 T cells to combat tumors. This unique capability of DCs positions DC-based vaccines as one of the leading strategies in cancer immunotherapy. However, tumors frequently induce a state of tolerance in DCs, resulting in suppressed tumor immunity and limiting the effectiveness of DC-based cancer vaccines.

Several obstacles hinder the success of DC vaccines, including tumor-mediated immunosuppression and the functional limitations of DCs differentiated in vitro. To address these challenges, researchers are exploring alternatives such as DC-derived exosomes (DCexos), which have gained attention as potential cell-free therapeutic vaccines. Additionally, in vivo DC-targeted vaccines and the use of naturally circulating blood DCs offer promising strategies compared to in vitro cultured DCs. Nonetheless, there are significant gaps in our understanding of the fundamental biology of these approaches, such as how DCexos and different DC subsets prime T cells, which impedes their translation into clinical applications. Furthermore, an enhanced understanding of how DCs interact with other immune cells, such as other DCs, B cells, and NK cells, is crucial in fully realizing the potential of DC-based vaccines.

This Special Issue welcomes new research articles and reviews that explore all aspects of dendritic cells and their contributions to vaccine development and cancer immunotherapy.

Dendritic cells (DCs) are central to cancer immunity, orchestrating both innate and adaptive immune responses. In melanoma and other solid tumors, however, their function is often impaired within the tumor microenvironment (TME), leading to weakened antitumor immunity and diminished responses to immune checkpoint inhibitors (ICIs) and adoptive tumor-infiltrating lymphocyte (TIL) therapy. Among the various cell-based immunotherapy approaches, DC therapy—particularly using blood-derived conventional DCs (cDCs)—holds considerable promise. Compared with traditional monocyte-derived DCs (moDCs), cDCs exhibit superior antigen processing and cross-presentation capacities. The therapeutic application of cDCs was initially pioneered in vaccine strategies involving ex vivo antigen loading and maturation, followed by administration to lymph nodes. More recently, intratumoral (IT) cDC immunotherapy has emerged as a strategy to reinvigorate the cancer-immunity cycle by engaging the full repertoire of tumor-associated antigens while limiting systemic toxicity. This review discusses the underlying biological mechanisms and summarizes the clinical outcomes of IT DC therapy in cancer. Notably, combination approaches incorporating IT cDCs with ICIs, oncolytic viruses, synthetic adjuvants, radiation, or cryotherapy are emerging as promising strategies to overcome both primary and acquired resistance to ICI monotherapy. Collectively, these findings highlight the potential of integrating IT cDC therapy with complementary immunotherapies in next-generation, cross-tumor treatment strategies. Full article
