Although considerable advancements have been achieved in clinical and fundamental research in recent decades, the enhancements in AKI diagnosis and therapeutic approaches, such as the development of emerging biomarkers including neutrophil gelatinase-associated lipocalin (NGAL) and liver fatty acid-binding protein (FABP1) for early detection of AKI and the exploration of “goal-directed\" hemodynamic treatment methods and renal replacement therapies, have yet to fulfill the demands of modern medicine. Extracellular vesicles (EVs) serve as pivotal messengers in cell-to-cell communication, exerting a vital impact on both physiological and pathological processes. They exhibit immense potential as disease regulators, innovative biomarkers, therapeutic agents, and drug delivery vehicles. In recent times, the diagnostic and therapeutic potential of EVs in AKI has garnered widespread recognition and exploration, making them a focal point in clinical research. Consequently, a comprehensive overview of EVs' role in AKI is of great importance. This review delves into the multifaceted roles of EVs from diverse cellular sources, including tubular epithelial cells (TECs), mesenchymal stem cells (MSCs), progenitor cells, platelets and macrophages, within the context of AKI. It scrutinizes their contributions to disease progression and mitigation, their diagnostic marker potential, and encompasses a variety of conventional and novel EVs extraction techniques suitable for AKI clinical applications. Moreover, it underscores four innovative strategies for engineering EVs to boost production efficiency, targeting precision, circulatory stability and therapeutic potency. These advancements pave the way for novel approaches in the diagnosis and treatment of AKI. We are optimistic that as research into EVs progresses, the future will bring about earlier detection, more tailored treatments, and a more holistic management of AKI.</div></div>","PeriodicalId":8762,"journal":{"name":"Bioactive Materials","volume":"48 ","pages":"Pages 149-170"},"PeriodicalIF":18.0,"publicationDate":"2025-02-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143437416","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Real-time monitoring, accurate diagnosis, and on-demand therapy are crucial to minimizing complications and saving lives. Herein, we propose a “monitor-and-treat” strategy for infected wound management by integrating the emerging development of bacterio-therapeutics and bio-optics. The upper layer consists of gelatin methacryloyl (GelMA)-collagen III methacryloyl (Col<sub>3</sub>MA) (GC), Reuterin (Reu) isolated from the probiotic <em>Lactobacillus reuteri</em> (L. reuteri) and microfluidic safflower polysaccharide (SPS)@GelMA microspheres using 3D printing technology. The lower layer is made of acryloylated glycine (ACG) hydrogel with tissue adhesion capability, which enables the hydrogel to adapt to the movement and stretching of the skin. By integrating temperature-sensitive polydimethylsiloxane (PDMS) optical fibers, the ACG-GC/Reu/SPS-PDMS hydrogel could accurately and steadily sense and send wound temperature information to intelligent devices for real-time monitoring of the healing status (“monitor”). The double-layered hydrogel not only inhibited bacterial survival and colonization (97.4 % against <em>E. coli</em> and 99 % against <em>S. aureus</em>), but also exhibited remarkable hemostatic properties. Furthermore, it was conducive to L929 cell proliferation and pro-angiogenesis, and promoted the polarization of pro‐inflammatory M1 macrophages to the anti‐inflammatory M2‐phenotype, therefore creating a favorable immune microenvironment at the wound site. Animal experiments using SD rats and Bama minipigs demonstrated that this hydrogel promoted wound closure, directed polarization to M2 macrophages, alleviated inflammation, enhanced neovascularization, therefore accelerating infected wound healing (“treat”). In addition, RNA-Seq analysis revealed the mechanism of action of ACG-GC/Reu/SPS-PDMS hydrogel in modulating key signaling pathways, including down-regulation of AMPK, IL-17, and NF-κB signaling pathways, activation of NLRP3 inflammatory vesicles, and enrichment of MAPK, TGF-β, PI3K-Akt, TNF, and VEGF signaling pathways. The modulation of these signaling pathways suggests that hydrogels play an important role in the molecular mechanisms that promote wound healing and tissue regeneration. Therefore, the design of this study provides an innovative and multifunctional bandage strategy that can significantly improve pathologic diagnosis and wound treatment.</div></div>","PeriodicalId":8762,"journal":{"name":"Bioactive Materials","volume":"48 ","pages":"Pages 118-134"},"PeriodicalIF":18.0,"publicationDate":"2025-02-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143420021","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Herein, inspired by the snake's molting process, a ShedWise device was developed by using the poly(propylene fumarate) polyurethane (PPFU) as the foundational material, which was clicked with hyperbranched polylysine (HBPL) and followed by conjugation with pro-endothelial functional Arg-Glu-Asp-Val peptide (REDV), and finally coated with a “self-sacrificing” layer having reactive oxygen species (ROS)-scavenging ability and degradability. During the acute inflammation in the initial stage of implantation, the ROS-responsive hyperbranched poly(acrylate-capped thioketone-containing ethylene glycol (HBPAK) coating effectively modulated the level of environmental inflammation and resisted initial protein adsorption, showcasing robust tissue protection. As the coating gradually “sacrificed”, the exposed hyperbranched HBPL-REDV layer recruited specifically endothelial cells and promoted surface endothelialization. In a rat vascular injury model, the ShedWise demonstrated remarkable efficiency in reducing vascular restenosis, protecting the injured tissue, and fostering re-endothelization of the target site.

By establishing a rat model of Achilles tendon injury, L-CHAP was demonstrated to comprehensively promoting tendon repair by enhancing macrophage efferocytosis and M2 polarization in vivo, finally leading to improvement of tendon ultrastructural and mechanical properties and motor function.
