摘要：Implanted biomaterials and devices face compromised functionality and efficacy in the long term owing to foreign body reactions and subsequent formation of fibrous capsules at the implant–tissue interfaces1,2,3,4. Here we demonstrate that an adhesive implant–tissue interface can mitigate fibrous capsule formation in diverse animal models, including rats, mice, humanized mice and pigs, by reducing the level of infiltration of inflammatory cells into the adhesive implant–tissue interface compared to the non-adhesive implant–tissue interface. Histological analysis shows that the adhesive implant–tissue interface does not form observable fibrous capsules on diverse organs, including the abdominal wall, colon, stomach, lung and heart, over 12 weeks in vivo. In vitro protein adsorption, multiplex Luminex assays, quantitative PCR, immunofluorescence analysis and RNA sequencing are additionally carried out to validate the hypothesis. We further demonstrate long-term bidirectional electrical communication enabled by implantable electrodes with an adhesive interface over 12 weeks in a rat model in vivo. These findings may offer a promising strategy for long-term anti-fibrotic implant–tissue interfaces.

摘要：Neuroendocrine carcinomas (NECs) are extremely lethal malignancies that can arise at almost any anatomic site. Characterization of NECs is hindered by their rarity and significant inter- and intra-tissue heterogeneity. Herein, through an integrative analysis of over 1,000 NECs originating from 31 various tissues, we reveal their tissue-independent convergence and further unveil molecular divergence driven by distinct transcriptional regulators. Pan-tissue NECs are therefore categorized into five intrinsic subtypes defined by ASCL1, NEUROD1, HNF4A, POU2F3, and YAP1. A comprehensive portrait of these subtypes is depicted, highlighting subtype-specific transcriptional programs, genomic alterations, evolution trajectories, therapeutic vulnerabilities, and clinicopathological presentations. Notably, the newly discovered HNF4A-dominated subtype-H exhibits a gastrointestinal-like signature, wild-type RB1, unique neuroendocrine differentiation, poor chemotherapeutic response, and prevalent large-cell morphology. The proposal of uniform classification paradigm illuminates transcriptional basis of NEC heterogeneity and bridges the gap across different lineages and cytomorphological variants, in which context-dependent prevalence of subtypes underlies their phenotypic disparities.

摘要：Recent evidence reveals hyper T follicular helper (Tfh) cell responses in systemic lupus erythematosus (SLE); however, molecular mechanisms responsible for hyper Tfh cell responses and whether they cause SLE are unclear. We found that SLE patients downregulated both ubiquitin ligases, casitas B-lineage lymphoma (CBL) and CBLB (CBLs), in CD4+ T cells. T cell-specific CBLs-deficient mice developed hyper Tfh cell responses and SLE, whereas blockade of Tfh cell development in the mutant mice was sufficient to prevent SLE. ICOS was upregulated in SLE Tfh cells, whose signaling increased BCL6 by attenuating BCL6 degradation via chaperone-mediated autophagy (CMA). Conversely, CBLs restrained BCL6 expression by ubiquitinating ICOS. Blockade of BCL6 degradation was sufficient to enhance Tfh cell responses. Thus, the compromised expression of CBLs is a prevalent risk trait shared by SLE patients and causative to hyper Tfh cell responses and SLE. The ICOS-CBLs axis may be a target to treat SLE.

摘要：Oligodendrocyte-lineage cells, including NG2 glia, undergo prominent changes in various neurodegenerative disorders. Here, we identify a neuroprotective role for NG2 glia against prion toxicity. NG2 glia were activated after prion infection in cerebellar organotypic cultured slices (COCS) and in brains of prion-inoculated mice. In both model systems, depletion of NG2 glia exacerbated prion-induced neurodegeneration and accelerated prion pathology. Loss of NG2 glia enhanced the biosynthesis of prostaglandin E2 (PGE2) by microglia, which augmented prion neurotoxicity through binding to the EP4 receptor. Pharmacological or genetic inhibition of PGE2 biosynthesis attenuated prion-induced neurodegeneration in COCS and mice, reduced the enhanced neurodegeneration in NG2-glia-depleted COCS after prion infection, and dampened the acceleration of prion disease in NG2-glia-depleted mice. These data unveil a non-cell-autonomous interaction between NG2 glia and microglia in prion disease and suggest that PGE2 signaling may represent an actionable target against prion diseases.

摘要：Despite great success of chimeric antigen receptor T (CAR-T) cells in hematological cancers, the efficacy in solid tumors is extremely restricted. Transforming growth factor-β (TGF-β) and hypoxia are key processes in the development of solid tumors, including the formation of neo-vasculature, dense extracellular matrix (ECM), and immunosuppression. TGF-β inhibition and hypoxia alleviation may be promising approaches to enhance activity of CAR-T cells in solid tumors. Therefore, a self-reinforcing nano-spearhead (BM/LPsiTGF-β NPs) is developed to collaboratively remodel tumor microenvironment (TME) through albumin-mediated tumor targeted delivery of TGF-β siRNA and the nano enzyme MnO2. BM/LPsiTGF-β NPs efficiently eliminates ECM by down-regulation of TGF-β. Additionally, BM/LPsiTGF-β NPs also produces abundant O2 and down-regulates HIF-α, leading to normalized vasculature and improved tumor immunosuppression. More importantly, the ECM degradation induced by BM/LPsiTGF-β NPs forms a self-reinforcing loop, further promoting greater tumor penetration of BM/LPsiTGF-β NPs and CAR-T cells. Due to robust TME remodeling capacity of BM/LPsiTGF-β NPs, the therapeutic efficacy of Mesothelin (MSLN) CAR-T cells against triple negative breast cancer (TNBC) are enhanced both in vitro and in vivo. This nano-spearhead provides a good regimen for potent TME remodeling and gives rise to enhanced CAR-T cell efficacy in TNBC treatment.

摘要：Efforts to develop advanced bone substitutes for effective bone regeneration in substantial defects have led to the fabrication of tissue-engineered scaffolds. These scaffolds, featuring hierarchical structures, specific chemical compositions, and functional qualities, are essential in mimicking native bone tissue. Inspired by the biomineralization process, hydrothermal treatment is used to synthesize micro-/nano-hydroxyapatite bioceramics functionalized with tea polyphenols (TP-nwHA), closely resembling the structure of bone-like apatite induced by hydroxyapatite bioceramics in vivo. The in vitro results demonstrate TP-nwHA's superior biocompatibility, enhancing cell proliferation and adhesion. Furthermore, TP-nwHA scaffolds significantly influence mesenchymal stem cells, promoting osteogenic differentiation while inhibiting osteoclastogenic differentiation. The upregulation of osteogenic proteins BMP2 and ITGB1, along with the downregulation of osteoclastic proteins FGF21 and IGFBP1, demonstrate the synergistic effect of the biomimetic structure and polyphenols on the activation of the MAPK signaling pathway. In vivo, TP-nwHA showe early angiogenic capabilities, leading to improved bone regeneration in critical-size femoral bone defects in osteoporotic rats. Histological staining confirms the complete bridging of defects with new bone tissue in the TP-nwHA group, and nanoindentation tests indicate the formation of mature mineralized bone tissue. Collectively, these findings suggest a novel strategy for fabricating bone-mimicking constructs with potential applications in disease modeling.

摘要：Chemodynamic therapy (CDT) has emerged as a novel approach to overcome cancer resistance and enhance anticancer efficacy. Despite the considerable effort devoted to current chemodynamic therapeutic agents, developing efficient delivery systems to induce ferroptosis remains demanding due to their limited efficacy and lack of selectivity. Herein, an iron-based single-atom upconversion photocatalyst (UmFe-OA@hPM) mimicking natural horseradish peroxidases has been developed. This nanoformulation not only targets tumors via the existence of a hybrid platelet membrane (hPM) coating but also generates excessive hydroxyl radicals in response to both tumor microenvironment and external laser irradiation. This nanoenzyme overcomes the low tissue penetration of UV light, which sensitizes the iron-doped graphitic carbon nitride network, attributed to the unique anti-Stokes shift from infrared to UV displayed by upconversion nanoparticles. Together with an increase in intracellular polyunsaturated fatty acid accumulation induced by oleanolic acid (OA), lipid peroxidation is significantly elevated, leading to the enhancement of CDT. UmFe-OA@hPM is demonstrated to induce significant ferroptosis in vitro, superior antitumor efficacy in breast cancer mouse models, and suppression of metastasis status when incorporated with an immune checkpoint blockade. These findings provide a potential strategy for developing a precisely controlled CDT to deal with aggressive cancers, especially in combination with immunotherapy.

摘要：Cancer immunotherapy emerges as a promising therapeutic modality, while its clinical application remains constrained by low tumor immunogenicity and immunosuppressive microenvironments. Herein, we report a unique superdimeric nanoassembly pattern by elaborately integrating cyclodextrin inclusion with dimeric prodrug, enabling spatio-temporally self-adaptive drug delivery and multimodal photo-immunotherapy. Specifically, it is precisely engineered through host-guest inclusion between a GSH-sensitive cyclodextrin-photosensitizer conjugate and an oxidation-responsive homodimer prodrug of NLG919. Notably, on-demand photosensitizer activation and aggregation-caused quenching relief significantly facilitates photodynamic induction of ICD. Meanwhile, photodynamic ROS together with the endogenous ROS collaboratively facilitate on-demand NLG919 activation and release, efficiently reversing the immunosuppressive microenvironments. As such, the superdimeric nanoassembly allows spatio-temporally cascade-potentiated photo-immunotherapy, starting from photosensitizer activation to ICD induction, NLG919 release and IDO inhibition. Finally, it exerts intense antitumor efficacy, abscopal effect and synergy with PD-L1 antibody in two mouse models. This study presents new insights into the design of nanomedicines for multimodal photo-immunotherapy.
