Abstract The efficiency of reactive oxygen species (ROS)‐mediated cancer therapy is restrained by intrinsic characteristics in the tumor microenvironment (TME), such as overexpressed glutathione (GSH), hypoxia and limited H 2 O . In this work, intelligent copper‐dropped calcium carbonate loading sonosensitizer Ce6 nanoparticles (Cu/CaCO 3 @Ce6, CCC NPs) are established to realize TME‐responsive self‐supply successively Ca 2+ ‐overloading‐strengthened chemodynamic therapy/sonodynamic (CDT/SDT).

Ferroptosis, an iron-dependent form of regulatory cell death, has garnered significant interest as a therapeutic target in cancer treatment due to its distinct characteristics, including lipid peroxide generation and redox imbalance. However, clinical application oncology is currently limited by issues such suboptimal efficacy potential off-target effects. The advent nanotechnology provided new way for overcoming these challenges through the development activatable magnetic nanoparticles (MNPs). These innovative MNPs are designed improve specificity ferroptosis induction. This Review delves into chemical biological principles guiding design ferroptosis-based therapies imaging-guided therapies. It discusses mechanisms attributes ferroptosis, composition MNPs, their mechanism action inducers, integration with advanced imaging techniques monitoring. Additionally, we examine convergence other strategies, chemodynamic therapy, photothermal photodynamic sonodynamic immunotherapy, within context nanomedicine strategies utilizing MNPs. highlights multifunctional surpass limitations conventional treatments, envisioning future drug-resistance-free, precision diagnostics treating recalcitrant cancers.

Biometallic ions play a crucial role in regulating the immune system. In recent years, cancer immunotherapy has become breakthrough treatment, achieving good efficacy wide range of cancers with its specificity and durability advantages. However, existing therapies still face challenges, such as tolerance escape. (e.g. zinc, copper, magnesium, manganese, etc.) can assist enhancing through activation cells, enhancement tumor antigen presentation, improvement microenvironment. addition, biometallic derivatives directly inhibit cell progression offer possibility effectively overcoming limitations current by promoting responses reducing immunosuppressive signals. This review explores potential application prospects immunotherapy, providing new ideas for future clinical metal part helping to guide development more effective safe therapeutic regimens.

The escape of bladder cancer from immunosurveillance causes monotherapy to exhibit poor efficacy; therefore, designing a multifunctional nanoparticle that boosts programmed cell death and immunoactivation has potential as treatment strategy. Herein, we developed facile one-pot coprecipitation reaction fabricate cluster-structured nanoparticles (CNPs) assembled Fe3O4 iron chlorophyll (Chl/Fe) photosensitizers. This nanoassembled CNP, theranostic agent, could perform red-NIR fluorescence change the redox balance by photoinduction reactive oxygen species (ROS) attenuate iron-mediated lipid peroxidation induction Fenton-like reaction. intravesical instillation Fe3O4@Chl/Fe CNPs modified with 4-carboxyphenylboronic acid (CPBA) may target BC wall through glycoproteins in cavity, allowing local killing cells photodynamic therapy (PDT)-induced singlet causing chemodynamic (CDT)-mediated ferroptosis. An interesting possibility is reprogramming tumor microenvironment immunosuppressive immunostimulatory after PDT-CDT treatment, which was demonstrated reduction PD-L1 (lower "off" signal effector immune cells), IDO-1, TGF-β, M2-like macrophages CD8+ T on sections. Moreover, enhance large-area distribution wall, improving antitumor efficacy increasing survival rates 0 91.7%. Our not only combined PDT-CDT-induced cytotoxicity, ROS production, ferroptosis facilitate but also opened up new horizons for eliminating effect simultaneous PDT-CDT.
