This study addresses the urgent need to develop treatments for BRAFi+MEKi-resistant glioma in novel mouse models and patient-derived materials. BRAFi+MEKi reveals glioma plasticity by heightening cell state transitions along glial differentiation trajectories, giving rise to astrocyte- and immunomodulatory oligodendrocyte (OL)-like states. PD-L1 upregulation in OL-like cells links cell state transitions to tumor evasion, possibly orchestrated by Galectin-3. BRAFi+MEKi induces interferon response signatures, tumor infiltration, and suppression of T cells. Combining BRAFi+MEKi with immune checkpoint inhibition enhances survival in a T cell-dependent manner, reinvigorates T cells, and outperforms individual or sequential therapies in mice. Elevated PD-L1 expression in BRAF-mutant versus BRAF-wildtype glioblastoma supports the rationale for PD-1 inhibition in patients.

Carbon-based materials demonstrate considerable potential for the development and use of effective wave-absorbing substances, attributed to their complex structure, lightweight nature, excellent corrosion resistance, and affordability. Notably, nitrogen-doped carbon-based two-dimensional (2D) materials exhibit a more pronounced depletion effect on electromagnetic waves owing to their increased specific surface area and numerous polarization states. This article presents the successful synthesis of nitrogen-doped carbon (NC) 2D flakes using a hydrothermal method. In addition, single Fe atoms were successfully incorporated onto their surfaces, forming Fe@NC. The wave-absorbing capabilities of the Fe@NC samples were considerably improved, achieving a minimum reflection loss (RLmin) of −69.22 dB at 11.48 GHz and an effective absorption bandwidth of 5.79 GHz. The enhancement in electromagnetic wave absorption is attributed to the synergistic effects of magnetic loss, relaxation processes, dipole polarization, and electrical conduction loss. The successful synthesis of Fe@NC opens up new avenues for the development of atomically dispersed wave-absorbing materials.","PeriodicalId":10344,"journal":{"name":"Chinese Physics Letters","volume":"41 12","pages":"128401-128401"},"PeriodicalIF":0.0,"publicationDate":"2024-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147901714","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
