H₂S-Reactivating Antitumor Immune Response after Microwave Thermal Therapy for Long-Term Tumor Suppression

ACS Nano, Journal Year: 2023, Volume and Issue: 17(19), P. 19242 - 19253

Published: Oct. 2, 2023

Microwave thermal therapy (MWTT) is one of the most potent ablative treatments known, with advantages like deep penetration, minimal invasion, repeatable operation, and low interference from bone gas. However, microwave (MW) not selective against tumors, residual tumors after incomplete ablation will generate immunosuppression, ultimately making prone to recurrence metastasis. Herein, a nano-immunomodulator (Bi-MOF-l-Cys@PEG@HA, BMCPH) proposed reverse immunosuppression reactivate antitumor immune effect through responsively releasing H2S in tumor cells for improving MWTT. Under MW irradiation, BMCPH mediate MWTT ablate release l-cysteine (l-Cys) react highly expressed cystathionine β-synthase H2S. The generated can inhibit accumulation myeloid-derived suppressor (MDSCs) promote expression cytotoxic T lymphocytes (CTLs). Moreover, Bi-MOF also scavenge reactive oxygen species (ROS), major means MDSCs-mediated further weaken immunosuppressive effect. Simultaneously, surface-covered HA gather CTLs around enhance response. This nano gas immunomodulator provides an idea sensitive tunable unstable molecules at sites. strategy response introduces direction reduce risk metastasis ablation.

Z-Scheme BiOBr/Ti-MOF Nanosheet Heterojunction for Enhanced Visible-Light-Driven Pollutants Degradation

Langmuir, Journal Year: 2025, Volume and Issue: unknown

Published: March 14, 2025

A Z-scheme photocatalyst could enhance charge separation and extend the photocatalytic activity under visible light, improving efficiency of pollutant degradation other photochemical processes. In this study, a low-energy, high-performance BiOBr/NH2-MIL-125 (Ti) nanosheet (BiOBr/Ti-MOF NS) heterojunction was efficiently synthesized through simple solvothermal method. Under light irradiation, photodegradation rate constant BiOBr/Ti-MOF NS for Rhodamine B (RhB) (k = 0.403 76 min–1) greater than that pure BiOBr 0.089 75 NH2-MIL-125 0.071 67 min–1). The 0.015 58 hexavalent chromium (Cr(VI)) also significantly higher 0.001 70 0.003 72 RhB completely degraded within 6 min, while reduction Cr(VI) reached 79.0% 100 min. Furthermore, possible mechanism in composites is proposed based on structural analysis radical quenching experiments. remarkable enhancement performance can be attributed to its optimized band structure, accelerated carrier transport separation, strong interfacial interaction, increased adsorption capacity pollutants. This study offers valuable insights designing highly efficient photocatalysts removal.
