微核激活cGAS-STING信号通路的机制及其肿瘤免疫功能

open access: yesZhejiang da xue xue bao. Yi xue ban = Journal of Zhejiang University. Medical sciences
环鸟苷酸-腺苷酸合成酶(cGAS)-干扰素基因刺激因子(STING)信号通路可监测微生物入侵和组织损伤等生理病理异常状态,是天然免疫系统的重要组成之一。作为DNA感受器,cGAS主要识别异常定位于细胞质的双链DNA(dsDNA),通过催化合成二级信使环鸟苷酸-腺苷酸启动由STING介导的Ⅰ型干扰素和炎症信号通路。微核是有丝分裂后期染色体错误分离的产物,也是细胞质dsDNA的重要来源之一。作为一类不稳定的亚细胞器结构,微核核膜倾向于不可逆的破裂,导致微核基因组DNA暴露在细胞质中 ...

线粒体调控肿瘤免疫的研究进展

open access: yesZhejiang da xue xue bao. Yi xue ban = Journal of Zhejiang University. Medical sciences
肿瘤细胞通过改变自身代谢以适应能量和生物合成的需求。线粒体作为肿瘤细胞代谢重编程的关键细胞器,其功能异常是癌症发生和进展的主要驱动因素。线粒体动力学和能量代谢途径的改变对免疫细胞活化、增殖和分化至关重要,肿瘤微环境通过诱导免疫细胞线粒体代谢重编程和线粒体动力学变化,影响肿瘤浸润免疫细胞的活化和功能,进而促进肿瘤免疫抑制微环境形成;线粒体应激介导的线粒体DNA泄露可通过激活多条天然免疫信号通路,如cGAS-STING、TLR9和NLRP3,在宿主抗肿瘤免疫响应和肿瘤免疫抑制微环境的塑造中扮演复杂的调控角色,

T细胞免疫在骨重建和骨再生中的研究进展

open access: yesZhejiang da xue xue bao. Yi xue ban = Journal of Zhejiang University. Medical sciences
骨重建和骨再生对于保持骨骼完整性和维持矿物质稳态至关重要。T淋巴细胞为适应性免疫的关键成员,通过产生一系列细胞因子和生长因子,在骨重建和骨再生过程中起着举足轻重的作用。在生理状态下,T淋巴细胞通过与间充质干细胞、成骨细胞、破骨细胞的交互作用参与骨稳态的维持;在病理状态下,T淋巴细胞通过与雌激素、糖皮质激素、甲状旁腺激素的协作参与不同类型骨质疏松的病理过程;在损伤后修复的骨折愈合过程中,T淋巴细胞在炎症血肿期、骨痂形成期和骨重建期发挥了不同的作用。因此,靶向T淋巴细胞成为调节骨稳态的潜在策略 ...

Ultrathin MnO2‐PEG‐PD‐L1 Nanosheets Enable Tumor Microenvironment Modulation and NIR‐II Photothermal Immunotherapy for Durable Control of Lung Cancer and Postoperative Recurrence

open access: yesRare Metals, Volume 45, Issue 6, June 2026.
ABSTRACT Lung cancer is one of the most common and deadly malignancies worldwide. Although immune checkpoint inhibitors, including PD‐1/PD‐L1 blockers, have benefited a subset of patients, response rates remain limited, and recurrence is frequent because of the immunosuppressive tumor microenvironment (TME), characterized by hypoxia and dysregulated ...

肿瘤免疫微环境中cGAS-STING信号通路的细胞间信号传递

open access: yesZhejiang da xue xue bao. Yi xue ban = Journal of Zhejiang University. Medical sciences
环鸟苷酸-腺苷酸合成酶(cGAS)-干扰素基因刺激因子(STING)信号通路是肿瘤免疫治疗中备受关注的靶点。模式识别受体cGAS识别胞质双链DNA(dsDNA),生成第二信使2´3´-环鸟苷酸-腺苷酸(cGAMP),活化接头蛋白STING,介导干扰素和促炎性细胞因子的产生,从而促进肿瘤免疫。肿瘤免疫微环境中cGAS-STING通路的细胞间信号传递维持并增强天然免疫应答,推动适应性免疫的发展。基于膜系统的细胞外囊泡运输、吞噬作用和细胞膜融合传递dsDNA、cGAMP以及活化的STING蛋白 ...

Titanium Implant Abutments With Polydopamine‐Mesoporous Cerium Dioxide Coatings for Enhanced Antibacterial, Anti‐Inflammatory, and Soft Tissue Integration Properties

open access: yesRare Metals, Volume 45, Issue 6, June 2026.
ABSTRACT The poor soft tissue integration around titanium implants creates a microgap that serves as a pathway for pathogen invasion, resulting in infection, inflammation, and the progression of peri‐implantitis. As the implant’s transmucosal component, the abutment determines the degree of peri‐implant soft tissue attachment.

A Wearable Colorimetric Sensor for Ultraviolet Monitoring via Radical‐Triggered Gold Nanoparticle Clustering

open access: yesRare Metals, Volume 45, Issue 6, June 2026.
ABSTRACT Reliable monitoring of ultraviolet (UV) radiation is critical for protecting human health, yet existing sensors often rely on costly or rigid components that hinder portability. Here we report a wearable, low‐cost colorimetric sensor for quantitative UV dosimetry, enabled by radical‐triggered aggregation of gold nanoparticles (AuNPs).
