Perturbing Organelle‐Level K+/Ca2+ Homeostasis by Nanotherapeutics for Enhancing Ion‐Mediated Cancer Immunotherapy

homeostasis. In this process, the elevated immunogenicity of tumor cells would evoke robust antitumor immune responses by driving the excretion of damage-associated molecular patterns (DAMPs). Importantly, this ion-immunotherapy strategy reshapes the immunosuppressive tumor microenvironment (TME), and awakens the systemic immune response and long-term immune memory effect, thus effectively inhibiting the growth of primary/distant tumors, orthotopic tumors as well as metastatic tumors in different mice models.
