Sumario: | Immunotherapy has dramatically changed prognosis for patients with malignant tumors. However, as a non-immunogenic tumor, pancreatic ductal adenocarcinoma (PDAC) has a low response to immunotherapy. Factors that contribute to the inefficiency of PDAC immunotherapy include the tumor microenvironment (TME) and its dense stroma, which acts as a barrier for drug delivery and immune cell infiltration. Recent studies have shown that nanoparticle-based therapeutic strategies have more promising applications in improving drug delivery and reversing the immunosuppressive TME for PDAC. Therefore, nanomaterial-based therapeutic approaches are expected to enhance the effectiveness of immunotherapy and improve prognosis of patients with PDAC. Here, we outline the status and dilemma of PDAC immunotherapy, and summarize the latest advances in nanoparticle-based treatment strategies to enhance the efficacy of PDAC immunotherapy. |
