As an emerging cancer treatment strategy, ferroptosis is greatly restricted by excessive glutathione (GSH) in tumor microenvironment (TME) and low reactive oxygen species (ROS) generation efficiency. Here, this work designs self‐assembled copper‐alanine nanoparticles (CACG) loaded with glucose oxidase (GOx) and cinnamaldehyde (Cin) for in situ glutathione activated and enzymatic cascade‐enhanced ferroptosis...
Although anticancer vaccines have achieved certain effects in early clinical practice, T cell immunity as the most common responsive pattern of anticancer vaccines is still limited by unsatisfied tumor recognition and inhibition efficiency. As the critical step of T cell immunity, uptake and presentation of specific antigen by antigen‐presenting cells (APC) can be activated by inflammation for enhancing...
Glioblastoma is the most common lethal malignant intracranial tumor with a low 5‐year survival rate. Currently, the maximal safe surgical resection, followed by high‐dose radiotherapy (RT), is a standard treatment for glioblastoma. However, high‐dose radiation to the brain is associated with brain injury and results in a high fatality rate. Here, integrated pharmaceutics (named D‐iGSNPs) composed...
By integrating the characteristics of each therapy modality and material chemistry, a multitherapy modality is put forward: tumor starvation triggered synergism with sensitized chemotherapy. Following starvation‐induced amplification of pathological abnormalities in tumors, chemotherapy is arranged to be locally activated and accurately reinforced to perfect multitherapy synergism from spatial and...
Efficacy and safety of chemotherapeutic drugs constitute two major criteria in tumor chemotherapy. Nanomedicines with tumor‐targeted properties hold great promise for improving the efficacy and safety. To design targeted nanomedicines, the pathological characteristics of tumors are extensively and deeply excavated. Here, the rationale, principles, and advantages of exploiting these pathological characteristics...
Chemotherapy is well recognized to induce immune responses during some chemotherapeutic drugs‐mediated tumor eradication. Here, a strategy involving blocking programmed cell death protein 1 (PD‐1) to enhance the chemotherapeutic effect of a doxorubicin nanoprodrug HA‐Psi‐DOX is proposed and the synergetic mechanism between them is further studied. The nanoprodrugs are fabricated by conjugating doxorubicin...
Hypoxia is reported to participate in tumor progression, promote drug resistance, and immune escape within tumor microenvironment, and thus impair therapeutic effects including the chemotherapy and advanced immunotherapy. Here, a multifunctional biomimetic core–shell nanoplatform is reported for improving synergetic chemotherapy and immunotherapy. Based on the properties including good biodegradability...
This study reports a double‐targeting “nanofirework” for tumor‐ignited imaging to guide effective tumor‐depth photothermal therapy (PTT). Typically, ≈30 nm upconversion nanoparticles (UCNP) are enveloped with a hybrid corona composed of ≈4 nm CuS tethered hyaluronic acid (CuS‐HA). The HA corona provides active tumor‐targeted functionality together with excellent stability and improved biocompatibility...
Molybdenum ditelluride nanosheets encapsulated in few‐layer graphene (MoTe2/FLG) are synthesized by a simple heating method using Te and Mo powder and subsequent ball milling with graphite. The as‐prepared MoTe2/FLG nanocomposites as anode materials for lithium‐ion batteries exhibit excellent electrochemical performance with a highly reversible capacity of 596.5 mAh g−1 at 100 mA g−1, a high rate...
Multidrug resistance (MDR) remains one of the biggest obstacles in chemotherapy of tumor mainly due to P‐glycoprotein (P‐gp)‐mediated drug efflux. Here, a transformable chimeric peptide is designed to target and self‐assemble on cell membrane for encapsulating cells and overcoming tumor MDR. This chimeric peptide (C16‐K(TPE)‐GGGH‐GFLGK‐PEG8, denoted as CTGP) with cathepsin B‐responsive and cell membrane‐targeting...
As a characteristic trait of most tumor types, metastasis is the major cause of the death of patients. In this study, a photothermal agent based on gold nanorod is coated with metal (Gd3+)‐organic (polyphenol) network to realize combination therapy for metastatic tumors. This nanotheranostic system significantly enhances antitumor therapeutic effects in vitro and in vivo with the combination of photothermal...
Tumor hypoxia severely limits the efficacy of traditional photodynamic therapy (PDT). Here, a liposome‐based nanoparticle (designated as LipoMB/CaO2) with O2 self‐sufficient property for dual‐stage light‐driven PDT is demonstrated to address this problem. Through a short time irradiation, 1O2 activated by the photosensitizer methylene blue (MB) can induce lipid peroxidation to break the liposome,...
The nanoplatform GNR‐ACPP‐PpIX (designated as GNR‐ACPI) is designed for dual image guided combined activatable photodynamic therapy (PDT) and photothermal therapy (PTT). In GNR‐ACPI, gold nanorods (GNRs) are modified with a protoporphyrin (PpIX, a PDT agent) conjugated activatable cell penetrating peptide (ACPP), which consists of the matrix metalloproteinases‐2 (MMP‐2) sensitive peptide sequence...
On page 3344, X.‐Z. Zhang and co‐workers present how versatile bioactive peptides could be constructed to possess multiple capabilities. Mesoporous silica nanoparticles modified with peptides could realize many types of functionalities, including site‐specific targeting, fluorescence imaging, and intracellular diagnosis, especially the controlled release of a drug or gene for tumor treatment.
During the last decade, using versatile, promising, and fascinating mesoporous silica nanoparticles (MSNs) as site‐specific and stimuli‐responsive drug delivery systems (DDSs) has received concentrated research interest. As one of the most attractive surface modification units, peptides have inherent bioactivity, biodegradability and biocompatibility. Recent progresses in the utilization of versatile...
An improved antitumor therapy can be achieved by rationally designing an intelligent nanomedicine with programmed functions to specifically eliminate tumors while leaving healthy tissues untouched. On page 733, X.‐Z. Zhang and co‐workers demonstrate a tailor‐made ZnO‐based nanococktail with a stealth capacity to trigger an intracellular cascade reaction, releasing drugs on‐demand for tumor‐specific...
In this work, a ZnO based nanococktail with programmed functions is designed and synthesized for self‐synergistic tumor targeting therapy. The nanococktail can actively target tumors via specific interaction of hyaluronic acid (HA) with CD44 receptors and respond to HAase‐rich tumor microenvironment to induce intracellular cascade reaction for controlled therapy. The exposed cell‐penetrating peptide...
