Abstract There is a desperate need for precise nanomedications to treat ischemic cerebral injury. Yet, the drawbacks of poor delivery efficiency and off‐target toxicity in pathologic parenchyma traditional antioxidants against stroke result inadequate brain accumulation. M13 bacteriophages are highly phagocytosed by M1‐polarized microglia can be carried toward neuroinflammatory sites. Here, bio‐active, inhalable, Ce 0.9 Zr 0.1 O 2 ‐backpacked‐M13 phage (abbreviated as CZM) developed demonstrates how taken up different phenotypes’ microglia. With M1 microglia's proliferating migrating, CZM extensively specifically delivered site core penumbra, where surviving nerve cells shielded from secondary oxidative stress inflammatory cascade initiated reactive oxygen species (ROS). non‐invasive administration, effectively alleviates damage apoptosis neurons eliminating ROS generated hyperactive secure effective strategy targeted therapy maladies offered this research.

Cancer immunotherapy has emerged as a pivotal approach for treating various types of cancer, incorporating strategies such chimeric antigen receptor T-cell (CAR-T) therapy, immune checkpoint blockade neoantigen peptides, mRNA vaccines, and small molecule modulators. However, the clinical efficacy these therapies is frequently constrained by significant adverse effects limited therapeutic outcomes. In recent years, integration nanotechnology into cancer gained considerable attention, showcasing notable advantages in drug delivery, targeted accumulation, controlled release, localized administration. This review focuses on nanomaterial-based immunotherapeutic strategies, particularly development application nanocarriers liposomes, lipid nanoparticles, polymeric self-assembling scaffolds. We examine how can enhance while minimizing analyze their potential translation.

Abstract Pyroptosis provides a novel perspective for the design of anti‐tumor strategies. However, when pyroptosis reaches plateau, its negative role becomes “defense” signaling to evade immune surveillance. Herein, triblock polymeric micelles TPT@PIO NPs are reported, including hydrophobic block backbone poly (propylene sulfide) (PPS), side chain disulfide bond‐bearing indomethacin (MABHD‐IND), hydrophilic poly(ethylene glycol) methyl ether methacrylate (OEGMA), and an encapsulated drug topotecan (TPT) through forces, exhibit excellent stability responsiveness oxidation‐reduction microenvironment. This dual treatment mode utilizes TPT trigger activation process uses IND eliminate escape by inhibiting COX‐2/PGE 2 pathway, ultimately making growth tumors being inhibited via synergy chemotherapy immunotherapy. Furthermore, failure immunosuppressive network accelerates infiltration CD8 + T cells into lungs impedes generation tumor nodules. The changes in levels cytokines caused memory effect enhance defense transfer as well. In general, ability regulate Janus‐faced nature acts indispensable suppressing proliferation metastasis.

Abstract Hypertrophic scar (HS) remains a major challenge for clinicians due to unsatisfactory therapeutic performance. Although inducing apoptosis of HS fibroblasts (HSFs) has proved be an effective nonsurgical treatment strategy, potential chemotherapy resistance HSFs makes the development new and efficient strategies highly demanding. Herein, ferroptosis‐apoptosis combined strategy is developed through supramolecular self‐assembly between cucurbit[7]uril (CB[7]) two bioactive agents, dihydroartemisinin (DHA) gold nanoclusters (AuNCs). The resulting self‐assembled nanoparticles, named CAD NPs, showed high guest loading efficiency prominent pH‐responsive degradability in acidic lysosomes HSFs. Importantly, both DHA AuNCs act synergistically generate excessive reactive oxygen species lipid peroxidation, leading mitochondrial damage, ultimately concurrent ferroptosis on Upon further into hydrogel microneedles facilitate their transdermal delivery, these NPs superior antiscar effects shortening span 3 weeks improving appearance, as demonstrated at rabbit ear model HS. present assembly‐based provides innovative guideline efficiently treating well other diseases.
