Abstract
Rapid, efficient, and precise cancer therapy is highly desired. Here, this work reports solvothermally synthesized photoactivatable Pt(IV)-coordinated carbon dots (Pt-CDs) and their bovine serum albumin (BSA) complex (Pt-CDs@BSA) as a novel orange light-triggered anti-tumor therapeutic agent. The homogeneously distributed Pt(IV) in the Pt-CDs (Pt: 17.2 wt%) and their carbon cores with significant visible absorption exhibit excellent photocatalytic properties, which not only efficiently releases cytotoxic Pt(II) species but also promotes hydroxy radical generation from water under orange light. When triggered with a 589 nm laser, Pt-CDs@BSA possesses the ultrastrong cancer cell killing capacities of intracellular Pt(II) species release, hydroxyl radical generation, and acidification, which induce powerful immunogenic cell death. Activation of Pt-CDs@BSA by a single treatment with a 589 nm laser effectively eliminated the primary tumor and inhibited distant tumor growth and lung metastasis. This study thus presents a new concept for building photoactivatable Pt(IV)-enriched nanodrug-based CDs for precision cancer therapy.

Abstract
The self-delivery of sonosensitizers and immunomodulators to tumor areas, which is highly recommended for enhancing sonodynamic immunotherapy, remains a challenge. Herein, a self-delivering nanodrug (HB-NLG8189, drug loading: ≈100 wt%) is developed by the small-molecule self-assembly of "HB" (a new clinical photosensitizer) and NLG8189 (indoleamine-(2,3)-dioxygenase (IDO) pathway inhibitor) for sonodynamic-augmented immunotherapy; this preparation method ensures the absence of excipient-related toxicity and immunogenicity. To evade immune recognition and prolong the circulation time, the HB-NLG8189 nanodrugs are camouflaged using macrophage cell membranes (MPCMs). The constructed HB-NLG8189@MPCM nanodrugs show an ability to preferentially accumulate within tumors. Upon ultrasound triggering, the HB-NLG8189@MPCM is able to generate reactive oxygen species efficiently for robust sonodynamic therapy; it induces immunogenic cell death, initiates an antitumor immune response to activate tumor-specific effector T cells, and promotes the secretion of inflammatory cytokines. The concomitant delivery of NLG8189 reverses the immunosuppressive tumor microenvironment by restraining IDO-1 activation and the intratumoral infiltration of regulatory T cells. Sonodynamic-augmented immunotherapy with HB-NLG8189@MPCM significantly inhibits the growth of both primary and distant tumors with little systemic toxicity. The biomimetic self-delivery nanodrug provides a promising paradigm for improving sonodynamic immunotherapy.

Abstract
Self-delivery of photosensitizer and immune modulator to tumor site is highly recommendable to improve the photodynamic immunotherapy yet remains challenging. Herein, self-delivery photoimmune stimulators (designated as iPSs) are developed for photodynamic sensitized tumor immunotherapy. Carrier-free iPSs are constructed by optimizing the noncovalent interactions between the pure drugs of chlorine e6 (Ce6) and NLG919, which avoid the excipients-raised toxicity and immunogenicity. Intravenously administrated iPSs prefer to passively accumulate on tumor tissues for a robust photodynamic therapy (PDT) with the induction of immunogenetic cell death (ICD) cascade to activate cytotoxic T lymphocytes (CTLs) and initiate antitumor immune response. Meanwhile, the concomitant delivery of NLG919 inhibits the activation of indoleamine 2,3-dioxygenase 1 (IDO-1) to reverse the immunosuppressive tumor microenvironment. Ultimately, the photodynamic sensitized immunotherapy with iPSs efficiently inhibit the primary and distant tumor growth with a low system toxicity, which would shed light on the development of self-delivery nanomedicine for clinical transformation in tumor precision therapy.

Abstract
A cancer vaccine is an important form of immunotherapy. Given their effectiveness for antigen processing and presentation, dendritic cells (DCs) have been exploited in the development of a therapeutic vaccine. Herein, a versatile polymersomal nanoformulation that enables generation of tumor-associated antigens (TAAs) and simultaneously serves as adjuvant for an in situ DC vaccine is reported. The chimeric cross-linked polymersome (CCPS) is acquired from self-assembly of a triblock copolymer, polyethylene glycol-poly(methyl methyacrylate- co-2-amino ethyl methacrylate (thiol/amine))-poly 2-(dimethylamino)ethyl methacrylate (PEG-P(MMA- co-AEMA (SH/NH2)-PDMA). CCPS can encapsulate low-dose doxorubicin hydrochloride (DOX) to induce immunogenic cell death (ICD) and 2-(1-hexyloxyethyl)-2-devinyl pyropheophorbide-a (HPPH), a photosensitizer to facilitate photodynamic therapy (PDT) for reactive oxygen species (ROS) generation. This combination is able to enhance the population of TAAs and DC recruitment, eliciting an immune response cascade. In addition, CCPS with primary and tertiary amines act as adjuvant, both of which can stimulate DCs recruited to form an in situ DC vaccine after combination with TAAs for MC38 colorectal cancer treatment. In vivo results indicate that the all-in-one polymersomal nanoformulation (CCPS/HPPH/DOX) increases mature DCs in tumor-draining lymph nodes (tdLNs) and CD8+ T cells in tumor tissues to inhibit primary and distant MC38 tumor growth following a single intravenous injection with a low dose of DOX and HPPH.
