Mannan-decorated STING-activating vaccine carrier for spatial coordinative stimulating antigen-specific immune responses

Fundamental Research 2025年第1期5卷 183-191页

作者： Liu, Liping Zhao, Jiayu Huang, Zichao Xu, Yudi Chen, Hongyu Qiao, Ruirui Song, Wantong Tang, Zhaohui Davis, Thomas P. Chen, Xuesi Key laboratory of Polymer Ecomaterials Changchun Institute of Applied Chemistry Chinese Academy of Sciences University of Science and Technology of China Jilin Biomedical Polymers Engineering laboratory Australian Institute of Bioengineering and nanotechnology The University of Queensland

In recent years, the use of nanotechnologies to improve immunotherapy efficiency has attracted increasing interest in preventive and therapeutic cancer vaccine design. However, current nanocarriers are restricted by difficulties in the systematic spatial coordinative transport of antigens, which greatly hampers the immune response efficacy of nanovaccines. Herein, we designed a mannan-decorated stimulator of the interferon genes (STING)-activating vaccine carrier for spatial coordinative stimulation of antigen-specific immune responses and elicitation of robust antitumor immunity. Mannan-decoration as the shell could significantly enhance the lymph node draining ability of the nanovaccines, especially in CD8+ dendritic cells (DCs). Azole molecule end-capped polylactic acid-polyethylenimine (PLA-PEI-4BImi) with innate stimulating activity was applied as the inner core for coordinating antigen-presenting cell activation and antigen cross-presentation. In the in vivo therapy study, single usage of this nanovaccine could achieve a 93% tumor suppression rate in the B16-OVA tumor model, which is superior to the commercialized aluminum adjuvant. This study demonstrates that a rational design of vaccine carriers for solving spatial transmission issues could greatly improve cancer vaccine efficiencies. © 2023

Spinal cord injuries lead to significant loss of motor, sensory, and autonomic functions, presenting major challenges in neural regeneration. Achieving effective therapeutic concentrations at injury sites has been a slow process, partly due to the difficulty of delivering drugs effectively. Nanoparticles, with their targeted delivery capabilities, biocompatibility, and enhanced bioavailability over conventional drugs, are garnering attention for spinal cord injury treatment. This review explores the current mechanisms and shortcomings of existing treatments, highlighting the benefits and progress of nanoparticle-based approaches. We detail nanoparticle delivery methods for spinal cord injury, including local and intravenous injections, oral delivery, and biomaterial-assisted implantation, alongside strategies such as drug loading and surface modification. The discussion extends to how nanoparticles aid in reducing oxidative stress, dampening inflammation, fostering neural regeneration, and promoting angiogenesis. We summarize the use of various types of nanoparticles for treating spinal cord injuries, including metallic, polymeric, protein-based, inorganic non-metallic, and lipid nanoparticles. We also discuss the challenges faced, such as biosafety, effectiveness in humans, precise dosage control, standardization of production and characterization, immune responses, and targeted delivery in vivo. Additionally, we explore future directions, such as improving biosafety, standardizing manufacturing and characterization processes, and advancing human trials. Nanoparticles have shown considerable progress in targeted delivery and enhancing treatment efficacy for spinal cord injuries, presenting significant potential for clinical use and drug development.

引用

Chinese Chemical Letters 2025年第2期36卷 289-296页

Prostate cancer(PCa) is characterized by high incidence and propensity for easy metastasis, presenting significant challenges in clinical diagnosis and treatment. Tumor microenvironment(TME)-responsive nanomaterials provide a promising prospect for imaging-guided precision therapy. Considering that tumor-derived alkaline phosphatase(ALP) is over-expressed in metastatic PCa, it makes a great chance to develop a theranostics system with ALP responsive in the TME. Herein, an ALP-responsive aggregationinduced emission luminogens(AIEgens) nanoprobe AMNF self-assembly was designed for enhancing the diagnosis and treatment of metastatic PCa. The nanoprobe exhibited self-aggregation in the presence of ALP resulted in aggregation-induced fluorescence, and enhanced accumulation and prolonged retention period at the tumor site. In terms of detection, the fluorescence(FL)/computed tomography(CT)/magnetic resonance(MR) multi-mode imaging effect of nanoprobe was significantly improved post-aggregation, enabling precise diagnosis through the amalgamation of multiple imaging modes. Enhanced CT/MR imaging can achieve assist preoperative tumor diagnosis, and enhanced FL imaging technology can achieve “intraoperative visual navigation”, showing its potential application value in clinical tumor detection and surgical guidance. In terms of treatment, AMNF showed strong absorption in the near infrared region after aggregation, which improved the photothermal treatment effect. Overall, our work developed an effective aggregation-enhanced theranostic strategy for ALP-related cancers.

A Two-Stream Hybrid Spatio-Temporal Fusion Network For sEMG-Based Gesture Recognition

引用

Instrumentation 2025年

作者： Ruiqi Han Juan Wang Jia Wang School of Mechanical and Electrical Engineering Xi'an University of Architecture and Technology Shanxi Key laboratory of Nanomaterials and nanotechnology Xi'an University of Architecture and Technology

With the advancement of human-computer interaction, surface electromyography(sEMG)-based gesture recognition has garnered increasing attention. However, effectively utilizing the spatio-temporal dependencies in sEMG signals and integrating multiple key features remain significant challenges for existing techniques. To address this issue, we propose a model named the Two-Stream Hybrid Spatio-Temporal Fusion Network(TS-HSTFNet).Specifically, we design a dynamic spatio-temporal graph convolution module that employs an adaptive dynamic adjacency matrix to explore the spatial dynamic patterns in the sEMG signals fully. Additionally, a spatio-temporal attention fusion module is designed to fully utilize the potential correlations among multiple features for the final fusion. The results indicate that the proposed TS-HSTFNet model achieves 84.96% and 88.08% accuracy on the Ninapro DB2 and Ninapro DB5 datasets, respectively, demonstrating high precision in gesture recognition. Our work emphasizes the importance of extracting spatio-temporal features in gesture recognition and provides a novel approach for multi-source information fusion.
