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.

Ultrasound (US)-triggered sonodynamic therapy (SDT), as a promising noninvasive therapeutic modality, has received ever-increasing attention in recent years. Its specialized chemical agents, named sonosensitizers, are activated by low-intensity US to produce lethal reactive oxygen species (ROS) for oncotherapy. Compared with phototherapeutic strategies, SDT provides many noteworthy opportunities and benefits, such deeper penetration depth, absence of phototoxicity, fewer side effects. Nevertheless, previous studies have also demonstrated its intrinsic limitations. Thanks the facile engineering nature nanotechnology, numerous novel nanoplatforms being applied this emerging field tackle these barriers achieve continuous innovations. In particular, combination other treatment strategies superior efficacy improving anticancer activity relative that monotherapies alone. Therefore, it is necessary summarize nanomaterial-assisted combinational cancer applications. Herein, design principles achieving synergistic effects based on nanomaterial methods highlighted. The ultimate goals stimulate better-quality combined schemes provide innovative ideas perspectives promoting future transformation clinical application.

Cancer immunotherapy has made tremendous clinical progress in advanced-stage malignancies. However, patients with various tumors exhibit a low response rate to because of powerful immunosuppressive tumor microenvironment (TME) and insufficient immunogenicity tumors. Photodynamic therapy (PDT) can not only directly kill cells, but also elicit immunogenic cell death (ICD), providing antitumor immunity. Unfortunately, limitations from the inherent nature complex TME significantly reduce efficiency PDT. Recently, smart nanomedicine-based strategies could subtly modulate pharmacokinetics therapeutic compounds optimize both PDT immunotherapy, resulting an improved effect. Here, emerging nanomedicines for PDT-driven cancer are reviewed, including hypoxia-reversed nanomedicines, nanosized metal-organic frameworks, subcellular targeted nanoparticles (NPs). Moreover, we highlight synergistic nanotherapeutics used amplify immune responses combined against Lastly, challenges future expectations field discussed.

Immunogenic cell death (ICD) elicited by photodynamic therapy (PDT) is mediated through generation of reactive oxygen species (ROS) that induce endoplasmic reticulum (ER) stress. However, the half-life ROS very short and intracellular diffusion depth limited, which impairs ER localization thus limits stress induction. To solve problem, we synthesized reduction-sensitive Ds-sP NPs (PEG-s-s-1,2-distearoyl-sn-glycero-3-phosphoethanolamine-N-[amino(polyethylene glycol)-2000] nanoparticles) loaded with an efficient ER-targeting photosensitizer TCPP-TER (4,4',4″,4'″-(porphyrin-5,10,15,20-tetrayl)tetrakis(N-(2-((4-methylphenyl)sulfonamido)ethyl)benzamide). The resulting Ds-sP/TCPP-TER could selectively accumulate in locally generate under near-infrared (NIR) laser irradiation, induced stress, amplified ICD, activated immune cells, leading to augmented immunotherapy effect. This study presents a novel ICD amplifying, PDT strategy can effectively eradicate primary tumors NIR exposure, as well distant abscopal

Abstract Bone defects combined with tumors, infections, or other bone diseases are challenging in clinical practice. Autologous and allogeneic grafts two main traditional remedies, but they can cause a series of complications. To address this problem, researchers have constructed various implantable biomaterials. However, the original pathological microenvironment defects, such as residual severe infection, diseases, could further affect regeneration. Thus, rational design versatile biomaterials integrated therapy regeneration functions is great demand. Many strategies been applied to fabricate smart stimuli-responsive materials for regeneration, stimuli related external physical triggers endogenous disease microenvironments involving multiple strategies. Typical include light irradiation, electric magnetic fields, ultrasound, mechanical stimuli. These transform internal atomic packing arrangements cell fate, thus enhancing tissue In addition strategy, some specific microenvironments, excess reactive oxygen species mild acidity pH reduction enzymes secreted by bacteria electronegative potential defect sites, be used biochemical activate Herein, we summarize discuss construction therapeutic regenerative functions. The mechanisms, applications, existing limitations newly designed also clarified.

New agents with particular specificity toward targeted bacteria and superefficacy in antibacterial activity are urgently needed facing the crisis of worldwide antibiotic resistance. Herein, a novel strategy by equipping bacteriophage (PAP) photodynamic inactivation (PDI)-active AIEgens (luminogens aggregation-induced emission property) was presented to generate type AIE–PAP bioconjugate superior capability for both imaging synergistic killing certain species bacteria. The targeting ability inherited from enabled bioconjugates specifically recognize host preserved infection phage itself. Meanwhile, AIE characteristic empowered them monitoring functionality, real-time tracking their interactions targets therefore realized via convenient fluorescence imaging. More importantly, PDI-active could serve as powerful situ photosensitizers producing high-efficiency reactive oxygen (ROS) under white light irradiation. As result, selective antibiotic-sensitive multi-drug-resistant (MDR) were successfully achieved vitro vivo tests excellent biocompatibility. This AIE–phage integrated would diversify existing pool inspire development promising drug candidates future.
