NIR‐Activatable Domino Cascade Catalysis Nanozyme Reactor for Multi‐Mechanism Synergistic Immunotherapy in Bladder Cancer

Advanced Science, EarlyView.
This study presents an intravesical delivery strategy of ferroptosis‐ and immunity‐inducing nanozyme‐loaded thermoresponsive hydrogels (FMCC@PNH) for enhanced bladder cancer therapy. Abstract Current intravesical therapies for bladder cancer after resection are limited by poor tissue penetration, off‐target effects, and insufficient efficacy.

Fermented Lacticaseibacillus Paracasei Cultures Ameliorate Colitis by Modulating Microbiota‐Derived Tryptophan Metabolism and Macrophage Polarization

Advanced Science, EarlyView.
A solid‐state fermented probiotic (PYW) is developed using wheat bran as substrate, containing high viable Lacticaseibacillus paracasei and bioactive metabolites. PYW alleviates intestinal inflammation by gut microbiota composition, enriching indole derivatives, activating aryl hydrocarbon receptor signaling, and regulating macrophage polarization. PYW

In Situ Lipoprotein‐seeking Dye for in Vivo Real‐Time Imaging of Lipid Dysregulation Diseases

Advanced Science, EarlyView.
This study develops lipoprotein‐seeking NIR‐II dyes that specifically bind circulating lipoproteins. These dyes form ultra‐stable complexes with endogenous lipoprotein, enabling real‐time, high‐contrast imaging of fatty liver and atherosclerotic plaques. Tunable binding kinetics allow customized imaging windows.

Irradiated Tumor Cell‐Derived Microparticles Activate Systemic Anti‐Tumor Immunity via the STING/NLRP3/GSDMD Axis in Neutrophils

Advanced Science, EarlyView.
Radiotherapy induces tumor cells to release microparticles (RT‐MPs) into the circulation. The mitochondrial DNA carried by these RT‐MPs activates the STING/NLRP3/GSDMD axis in splenic neutrophils, triggering IL‐1β secretion. This, in turn, enhances dendritic cell function and facilitates the formation of cytotoxic T lymphocytes, thereby promoting ...

转染CⅡTA基因上调小鼠树突状细胞表面MHC分子和共刺激分子的表达

Zhongguo shiyan zhenduanxue, 2007
目的探讨MHCⅡ类分子反式激活因子（MHC classⅡtransactivator,CⅡTA）基因对树突状细胞（Dendriticcell,DC）表面MHC-Ⅰ/-Ⅱ类分子及共刺激分子CD80、CD86的调节作用,为将树突状细胞应用于生物治疗奠定基础。方法从小鼠骨髓中大量扩增DC,用脂质体转染法将小鼠CⅡTA（mCⅡTA）基因转入DC中,用流式细胞术观察转染前、后DC表面MHCⅠ-/-Ⅱ类分子及CD80、CD86的表达。结果转染mCⅡTA基因使DC上MHC-Ⅰ/-Ⅱ分子的表达率由74.2%/66.7 ...

GlycoChat Uncovers Glycan–Lectin Circuits in the Tumor Microenvironment of Pancreatic Cancer

Advanced Science, EarlyView.
Aberrant glycosylation drives cancer progression, yet its role in the tumor microenvironment remains unclear. We developed GlycoChat to map glycan–lectin circuits at single‐cell resolution. We discovered that cancer cells induce immunosuppressive macrophage differentiation and impair phagocytosis through interactions with CLEC10A and SIGLEC3 ...

CD20+FCRL4+ B Cells Activate CD8+ T Cells via MHC‐I Restriction in Nasopharyngeal Carcinoma Anti‐Tumor Immunity

Advanced Science, EarlyView.
CD20⁺FCRL4⁺ B cells in nasopharyngeal carcinoma actively cross‐present exogenous tumor antigens via MHC‐I, enhancing CD8⁺ T‐cell activation, memory formation, and cytotoxicity. IFNγ‐driven WDFY4 upregulation facilitates this process. These findings reveal an unconventional B‐cell–mediated antitumor mechanism and indicate potential relevance to ...
