Abstract Bacteria-based tumor therapy has recently attracted wide attentions due to its unique capability in targeting tumors and preferentially colonizing the core area of tumor. Various therapeutic genes are also harbored into these engineering bacteria enhance their anti-tumor efficacy. However, it is difficult spatiotemporally control expression inserted site. Here, we engineer an ultrasound-responsive bacterium (URB) which can induce exogenous ultrasound-controllable manner. Owing advantage ultrasound tissue penetration, acoustic remote bacterial gene be realized by designing a temperature-actuated genetic switch. Cytokine interferon-γ (IFN-γ), important immune regulatory molecule that plays significant role immunotherapy, used test system. Our results show brief hyperthermia induced focused promotes IFN-γ gene, improving efficacy URB vitro vivo. study provides alternative strategy for bacteria-mediated immunotherapy.

Abstract Necroptosis, caspase‐independent programmed necrosis, has emerged as a therapeutic target to make dying cancer cells stimulants for antitumor immune responses. The clinical translations exploiting necroptosis, however, have been limited since most downregulate receptor‐interacting protein kinase 3 (RIPK3) key enzyme necroptosis. Herein, nanobubbles (NBs) that can trigger RIPK3‐independent facilitating cell‐membrane rupture via the acoustic cavitation effect are reported. NBs, imbibing perfluoropentane gas precursor, prepared using an amphiphilic polymer conjugate, composed of PEGylated carboxymethyl dextran hydrophilic backbone and chlorin e6 hydrophobic sonosensitizer. When exposed ultrasound, NBs efficiently promote release biologically active damage‐associated molecular patterns by inducing burst‐mediated disintegration. Consequently, necroptosis‐inducible significantly improve immunity maturation dendritic activation CD8 + cytotoxic T both in vitro vivo. In addition, combination checkpoint blockade leads complete regression primary tumor beneficial activity against metastatic tumors RIPK3‐deficient CT26 tumor‐bearing mouse model. Overall, innovative NB causes immunogenic cell death necroptosis is promising enhancer immunotherapy.

Cancer remains a severe threat to human health. To date, although various therapeutic methods, including radiotherapy (RT), chemotherapy, chemodynamic therapy (CDT), phototherapy, starvation therapy, and immunotherapy, have entered new stage of rapid progress in cancer theranostics, their limited effect significant side effects need be considered carefully. With the development nanotechnology, marriage nanomaterials methods provides practical possibility improve deficiencies therapy. Notably, metal-organic frameworks (MOFs) composed ions/clusters bridging ligands through coordination bonds been widely applied deal with drawbacks different such as effects, low stability, poor efficacy, owing controllable morphologies, tailorable diameters, diverse compositions, tunable porosities, high specific surface areas, facile functionalization, good biocompatibility.

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

Abstract Immunotherapy has made remarkable strides in cancer therapy over the past decade. However, such emerging still suffers from low response rates and immune‐related adverse events. Various strategies have been developed to overcome these serious challenges. Therein, sonodynamic (SDT), as a non‐invasive treatment, received ever‐increasing attention especially treatment of deep‐seated tumors. Significantly, SDT can effectively induce immunogenic cell death trigger systemic anti‐tumor immune response, termed immunotherapy. The rapid development nanotechnology revolutionized effects with robust induction. As result, more innovative nanosonosensitizers synergistic modalities are established superior efficacy safe profile. In this review, recent advances immunotherapy summarized particular emphasis on how be explored harness for amplifying response. Moreover, current challenges field prospects its clinical translation also presented. It is anticipated that review provide rational guidance facilitate nanomaterials‐assisted immunotherapy, helping pave way next‐generation eventually achieve durable patients.

Recent years have witnessed increasingly rapid advances in nanocarrier-based biomedicine aimed at improving treatment paradigms for cancer. Nanogels serve as multipurpose and constructed vectors formed via intramolecular cross-linking to generate drug delivery systems, which is attributed predominantly their satisfactory biocompatibility, bio-responsiveness, high stability, low toxicity. Recently, immunotherapy has experienced unprecedented growth become the preferred strategy cancer treatment, mainly involves mobilisation of immune system an enhanced anti-tumour immunity tumour microenvironment. Despite inspiring success, immunotherapeutic strategies are limited due response rates immune-related adverse events. Like other nanomedicines, nanogels comparably by lower focal enrichment upon introduction into organism injection. Because three-dimensional cross-linked aqueous materials that exhibit similar properties natural tissues structurally stable, they can comfortably cope with shear forces serum proteins bloodstream, longer circulation life increases chance nanogel accumulation tumour, conferring deep penetration. The large specific surface area reduce or eliminate off-target effects introducing stimuli-responsive functional groups, allowing multiple physical chemical modifications purposes improve targeting cell subpopulations organs, increasing bioavailability drug, a events on therapies. slow release reaching site facilitates long-term awakening host's system, ultimately achieving therapeutic effects. As effective candidate immunotherapy, nanogel-based been widely used. In this review, we summarize recent deliver immunomodulatory small molecule drugs, antibodies, genes cytokines, target antigen presenting cells, form vaccines, enable chimeric receptor (CAR)-T therapy.
