Abstract
Immunoadjuvants, as an indispensable component of tumor vaccines, can observably enhance the magnitude, breadth, and durability of antitumor immunity. However, current immunoadjuvants suffer from different issues such as weak immunogenicity, inadequate cellular internalization, poor circulation time, and mono-functional bioactivity. Methods: Herein, we construct Fe3+-Shikonin metal-phenolic networks (FeShik) nanomedicines as immunogenic cell death (ICD) stimulants and multifunctional immunoadjuvants for tumor vaccination. The multifunctionality of FeShik nanomedicines is investigated by loading ovalbumin (OVA) as the model antigen to construct OVA@FeShik nanovaccines or 4T1 tumor cell fragment (TF) as homologous antigen to construct TF@FeShik nanovaccines. In vitro examinations including GSH responsive, •OH generation, colloid stability, cellular uptake, cytotoxicity mechanism of ferroptosis and necroptosis, ICD effect, the promotion of DC maturation and antigen cross-presentation were studied. In vivo observations including pharmacokinetics and biodistribution, antitumor effect, abscopal effect, immune memory effect, and biosafety were performed. Results: The presence of FeShik nanomedicines can significantly prolong the blood circulation time of antigens, increasing the bioavailability of antigens. Upon phagocytosis by tumor cells, FeShik nanomedicines can disassemble into Fe2+ and Shikonin in response to tumor microenvironments, leading to ICD of tumor cells via ferroptosis and necroptosis. Consequently, ICD-released autologous tumor cell lysates and pro-inflammatory cytokines not only stimulate DC maturation and antigen cross-presentation, but also promote macrophage repolarization and cytotoxic T lymphocyte infiltration, resulting in the activation of adaptive immune responses toward solid tumors. Conclusion: In a word, our FeShik supramolecular nanomedicines integrate bioactivities of ICD stimulants and immunoadjuvants, such as eradicating tumor cells, activating antitumor immune responses, modulating immunosuppressive tumor microenvironments, and biodegradation after immunotherapy. Encouraged by the diversity of polyphenols and metal ions, our research may provide a valuable paradigm to establish a large library for tumor vaccination.

Abstract
In tumor nanovaccines, nanocarriers enhance the delivery of tumor antigens to antigen-presenting cells (APCs), thereby ensuring the robust activation of tumor antigen-specific effector T-cells to kill tumor cells. Through employment of their high immunogenicity and nanosize, we have developed a "Plug-and-Display" delivery platform on the basis of bacterial outer membrane vesicles (OMVs) for tumor nanovaccines (NanoVac), which can rapidly display different tumor antigens and efficiently eliminate lung metastases of melanoma. In this study, we first upgraded the NanoVac to increase their antigen display efficiency. However, we found that the presence of a subcutaneous xenograft seriously hampered the efficiency of NanoVac to eliminate lung metastases, with the subcutaneous xenograft mimicking the primary tumor burden in clinical practice. The primary tumor secreted significant amounts of granulocyte colony-stimulating factor (G-CSF) and altered the epigenetic features of granulocyte monocyte precursor cells (GMPs) in the bone marrow, thus disrupting systemic immunity, particularly the function of APCs, and ultimately resulting in NanoVac failure to affect metastases. These changes in the systemic immune macroenvironment were plastic, and debulking surgery of primary tumor resection reversed the dysfunction of APCs and failure of NanoVac. These results demonstrate that, in addition to the formulation design of the tumor nanovaccines themselves, the systemic immune macroenvironment incapacitated by tumor development is another key factor that cannot be ignored to affect the efficiency of tumor nanovaccines, and the combination of primary tumor resection with NanoVac is a promising radical treatment for widely metastatic tumors.

Abstract
Toll-like receptor (TLR) agonists are potent immune-stimulators that hold great potential in vaccine adjuvants as well as cancer immunotherapy. However, TLR agonists in free form are prone to be eliminated quickly by the circulatory system and cause systemic inflammation side effects. It remains a challenge to achieve precise release of TLR7/8 agonist in the native form at the receptor site in the endosomal compartments while keeping stable encapsulation and inactive in nontarget environment. Here, we report a pH-/enzyme-responsive TLR7/8 agonist-conjugated nanovaccine (TNV), which responds intelligently to the acidic environment and cathepsin B in the endosome, precisely releases TLR7/8 agonist to activate its receptor signaling at the endosomal membrane, stimulates DCs maturation, and provokes specific cellular immunity. In vivo experiments demonstrate outstanding prophylactic and therapeutic efficacy of TNV in mouse melanoma and colon cancer. The endosome-targeted responsive nanoparticle strategy provides a potential delivery toolbox of adjuvants to advance the development of tumor nanovaccines.
