Abstract Diabetic osteoporosis (DOP) is a significant complication that poses continuous threat to the bone health of patients with diabetes; however, currently, there are no effective treatment strategies. In diabetes, increased levels ferroptosis affect osteogenic commitment and differentiation mesenchymal stem cells (BMSCs), leading skeletal changes. To address this issue, we aimed target propose novel therapeutic approach for DOP. We synthesized ferroptosis-suppressing nanoparticles, which could deliver curcumin, natural compound, marrow using tetrahedral framework nucleic acid (tFNA). This delivery system demonstrated excellent curcumin bioavailability stability, as well synergistic properties tFNA. Both in vitro vivo experiments revealed nanoparticles enhance mitochondrial function by activating nuclear factor E2-related 2 (NRF2)/glutathione peroxidase 4 (GPX4) pathway, inhibiting ferroptosis, promoting BMSCs diabetic microenvironment, reducing trabecular loss, increasing formation. These findings suggest curcumin-containing DNA tetrahedron-based have promising potential DOP other ferroptosis-related diseases.

Abstract Hydrocephalus is one of the most common brain disorders and a life‐long incurable condition. An empirical “one‐size‐fits‐all” approach cerebrospinal fluid (CSF) shunting remains mainstay hydrocephalus treatment effective pharmacotherapy options are currently lacking. Macrophage‐mediated ChP inflammation CSF hypersecretion have recently been identified as significant discovery in pathogenesis hydrocephalus.

This construct can significantly knockdown expression OSR1, along their downstream ion channel proteins epithelial cells, thereby leading to decrease secretion. Moreover, these findings indicate that TSOs effectively inhibit M0 M1 phenotypic switch macrophages MAPK pathways, thus mitigating cytokine storm. vivo post‐hemorrhagic (PHH) models, reduce secretion rates, alleviate inflammation, prevent onset These compelling results highlight potential promising therapeutic option for managing hydrocephalus, applications future.

Unnecessary exposure to ionizing radiation (IR) often causes acute and chronic oxidative damages normal cells organs, leading serious physiological even life-threatening consequences. Amifostine (AMF) is a validated radioprotectant extensively applied in chemotherapy medicine, but the short half-life limits its bioavailability clinical applications, remaining as great challenge be addressed. DNA-assembled nanostructures especially tetrahedral framework nucleic acids (tFNAs) are promising nanocarriers with preeminent biosafety, low biotoxicity, high transport efficiency. The tFNAs also have relative long-term maintenance for structural stability excellent endocytosis capacity. We therefore synthesized tFNA-based delivery system of AMF multi-organ radioprotection (tFNAs@AMF, termed nanosuit). By establishing mice models accidental total body irradiation (TBI) radiotherapy model Lewis lung cancer, we demonstrated that nanosuit could shield from IR-induced DNA damage by regulating molecular biomarkers anti-apoptosis anti-oxidative stress. In model, pretreated exhibited satisfactory alteration superoxide dismutase (SOD) activities malondialdehyde (MDA) contents, functional recovery hematopoietic system, reducing pathological safeguarding lethal radiation. More importantly, showed selective organs without interferences tumor control cancer.

ACS Nano, Год журнала: 2023, Номер 17(22), С. 22960 - 22978

Опубликована: Ноя. 6, 2023

Infected bone defects (IBDs) exhibit impaired healing due to excessive inflammation triggered by pathogen-associated molecular patterns (PAMPs) from bacteria. As a vital factor in orchestrating immune responses, mitochondrial homeostasis maintenance is central blockade. This research developed chameleon-like nanoplatform covering hydroxyapatite nanoparticles with cerium ion coordinated tannic acid supramolecular network (HA@Ce-TA), which adaptively functions regulate based on intra- and extracellular environments. Extracellularly, acidic conditions activate HA@Ce-TA's peroxidase/oxidase-mimicking activity produce reactive oxygen species (ROS), external near-infrared (NIR) irradiation excites nanoscale Ce-TA hyperthermia, found explained chemical computation. ROS production photothermal therapy can eliminate bacteria effectively reduce stress. Intracellularly, HA@Ce-TA remodels dynamics upregulating fusion genes eliminates mimicking superoxidase/catalase. Consequently, this comprehensive modulation of inhibits inflammasome overactivation. In vitro vivo studies showed modulate the mitochondria-centered inflammatory cascade enhance IBD treatment, highlighting potential engineering nanotherapeutics recalibrate as an infected disease-modifying intervention.
