The utilization of traditional therapies (TTS), such as chemotherapy, reactive oxygen species-based therapy, and thermotherapy, to induce immunogenic cell death (ICD) in tumor cells has emerged a promising strategy for the activation antitumor immune response. However, limited effectiveness most TTS inducing ICD effect tumors hinders their applications combination with immunotherapy. To address this challenge, various intelligent strategies have been proposed strengthen these TTS, then achieve synergistic efficacy These primarily focus on augmenting or facilitating antigen (released by cells) presentation process during they are systematically summarized review. Finally, existing bottlenecks prospects application regulation also discussed.

Abstract Immunotherapy is a promising new approach for tumor treatment. However, its clinical application hindered by insufficient immunogenicity, hypoxia, and immunosuppressive microenvironment (TME). Here, oxygen pump microneedles (OPMNs) loaded with zinc‐doped copper sulfide nanoflowers (ZCS NFs) PD‐L1 small interfering RNA (siPD‐L1) (OPMNs‐ZCS@siPD‐L1) are developed boosting immunotherapy. OPMN‐ZCS@siPD‐L1 enhances immunogenicity through ZCS NFs inducing cuproptosis, reverses TME siPD‐L1, promotes drug penetration, ameliorates hypoxia bubbles. More importantly, cuproptosis‐induced mitochondrial DNA (mtDNA) together Zn 2+ co‐activate the STING pathway, triggering robust immune response. increases sensitivity to cuproptosis induces immunogenic cell death (ICD) in vivo vitro, which significantly inhibits progression metastasis. The novel strategy of “increasing throttle” (cuproptopsis‐mediated activation & ICD effect) combined “releasing brake” (PD‐L1 inhibition improvement) provides enhancing percutaneous

Ferroptosis, as a type of regulated cell death, can trigger the release damage-associated molecular patterns from cancer cells and lead to enhancement immune recognition. Fenton reaction-mediated chemodynamic therapy could initiate ferroptosis by generating lipid peroxides, but its efficiency would be greatly restricted insufficient H2O2 antioxidant system within tumor. Herein, this work reports successful preparation self-supplied glutathione (GSH)-depletion therapeutic nanocomposites (Cu2O@Au) through in situ growth Au nanoparticles on surface cuprous oxide (Cu2O) nanospheres. Upon delivery into cells, released Cu2O consume endogenous H2S colorectal form Cu31S16 nanoparticles, while NPs catalyze glucose generate gluconic acid. The self-supplying lower acidity amplify Cu ion-induced Fenton-like reaction. Meanwhile, consumption reduce GSH generation disrupting pentose phosphate pathway. Additionally, Cu2+/Cu+ catalytic cycle promotes depletion GSH, leading peroxide accumulation ferroptosis. It was found that onset triggered Cu2O@Au immunologic promote dendritic maturation T-cell infiltration, finally enhance antitumor efficacy PD-L1 antibody. In summary, collaborative action produces remarkable effect, which provides promising treatment strategy for cancer.

Abstract Immunotherapy offers a promising avenue for reducing tumor metastasis and recurrence but faces challenges from the immunosuppressive microenvironment (TIME) restricted antigen presentation. To address these challenges, this study have developed an innovative approach utilizing molybdenum (Mo)‐doped Prussian blue nanoparticles coated with cancer cell membrane (CCM), referred to as PMo@CCM. This novel nanoplatform excels in performing photothermal therapy (PTT), while Mo Fe components effectively deplete glutathione (GSH) generate reactive oxygen species (ROS), thereby significantly enhancing chemodynamic (CDT) remodeling TIME. The synergistic PTT/CDT not only induces immunogenic death (ICD) also facilitates CCM coating further supplies antigens prompts dendritic (DC) maturation. comprehensive strategy markedly enhances effectiveness of immunotherapy, evidenced by significant increase T activation. Moreover, use programmed protein 1 antibodies (anti PD‐1) blocks PD‐1 immune checkpoint pathway. RNA sequencing analysis has identified genes associated observed substantial reduction growth. In conclusion, PMo@CCM enables homologously targeted therapy, guided magnetic resonance imaging (PTI&MRI), impeding progression both primary metastatic tumors.

Tumor vaccines, an important part of immunotherapy, prevent cancer or kill existing tumor cells by activating restoring the body's own immune system. Currently, various formulations vaccines have been developed, including cell membrane DNA mRNA polypeptide virus-vectored and tumor-in-situ vaccines. There are also multiple delivery systems for such as liposomes, vesicles, viruses, exosomes, emulsions. In addition, to decrease risk escape tolerance that may exist with a single vaccine, combination therapy radiotherapy, chemotherapy, checkpoint inhibitors, cytokines, CAR-T therapy, photoimmunotherapy is effective strategy. Given critical role in here, we look back history discuss antigens, adjuvants, formulations, systems, mechanisms, future directions
