The goal of vaccine-based cancer immunotherapy is to induce a tumor-specific immune response that ultimately reduces tumor burden. However, the immune system is often tolerant to antigens presented by the tumor, as the cancer originates from within a patient and is therefore recognized as self. This article reviews selected clinical strategies for overcoming this immune tolerance, and approaches to enhance generation of immunity to tumor-associated antigens by activating innate immunity, potentiating adaptive immunity, reducing immunosuppression, and enhancing tumor immunogenicity. Success in the field of cancer vaccines has yet to be fully realized, but intelligent choice of immunomodulators, tumor antigens and patient populations will likely lead to clinically relevant uses for cancer vaccines.

Hepatocellular carcinoma (HCC) is a highly prevalent malignancy with limited treatment efficacy despite advances in immune checkpoint blockade (ICB) therapy. The inherently weak immune responses in HCC necessitate novel strategies to improve anti-tumor immunity and synergize with ICB therapy. Kinesin family member 20A (KIF20A) is a tumor-associated antigen (TAA) overexpressed in HCC, and it could be a promising target for vaccine development.

Despite the potential of sonodynamic therapy (SDT) in treating malignant tumors, the lack of effective sonosensitizers has limited its clinical implementation. In this study, we explored the relationship between the heteroatom doping concentration in metal-organic frameworks and interface formation after pyrolysis by regulating the addition of manganese sources and successfully derived Z-scheme heterojunctions MnO/(A/R)TiO (MTO) in situ from MIL-125-NH (Ti/Mn). The electron transfer pathway introduced by interfacial contact promoted carrier separation and greatly preserved the effective redox components, significantly influencing the performance of reactive oxygen species generation.

Metastatic breast cancer (MBC) is generally considered an incurable disease and even though new treatments are available, the median survival is approximately three years. The introduction of immune therapies for MBC highlights the importance of the immune system in cancer progression and treatment. CD163 anti-inflammatory myeloid cells, including tumor associated macrophages (TAMs), are known to be of relevance in early breast cancer but their role in MBC is not yet established.

Natural killer (NK) cells are essential elements of the innate immune response against tumors and viral infections. NK cell activation is governed by NK cell receptors that recognize both cellular (self) and viral (non-self) ligands, including MHC, MHC-related, and non-MHC molecules. These diverse receptors belong to two distinct structural families, the C-type lectin superfamily and the immunoglobulin superfamily.

Survivin, a tumor-associated antigen, is overexpressed in several solid tumors, indicating poor prognosis. We aimed to evaluate the clinical significance and role of survivin as a therapeutic target for NEN.
