Metabolic dysfunction-associated steatotic liver disease (MASLD) has a high global incidence and associated with increased lipid accumulation in hepatocytes, elevated hepatic enzyme levels, liver fibrosis, and hepatic carcinoma. Despite decades of research and significant advancements, the treatment of MASLD still faces formidable challenges. Nanoprobes for diagnostics and nanomedicine for targeted drug delivery to the liver present promising options for MASLD diagnosis and treatment, enhancing both imaging contrast and bioavailability. Here, we review recent advances in nanotechnology applied to MASLD diagnosis and treatment, specifically focusing on drug delivery systems targeting hepatocytes, hepatic stellate cells, Kupffer cells, and liver sinusoidal endothelial cells. This review aims to provide an overview of nanomedicine's potential in early MASLD diagnosis and therapeutic interventions, addressing related complications.

Gastrointestinal tract toxicity represents a serious adverse effect of chemotherapy, leading to reduced quality of life and survival. For instance, irinotecan (CPT-11) usually causes severe gastrointestinal toxicity, with a lack of effective therapeutic interventions, making treatment often unsustainable. Therefore, development of an effective and safe therapy is crucial for improving chemotherapy efficacy and the patients’ quality of life. In this work, we developed a novel approach involving the helical-shaped cyanobacterium microalgae, Spirulina platensis (SP), to carry the bornyl acetate (BA)-loaded chitosan nanoparticles to enhance drug retention in the small intestine. We demonstrated the protection effect of BA against chemotherapy-induced intestinal injury using an epithelial cell model. In a mouse model, orally administered BA-ChNPs@SP accumulated in the small intestine and attenuated inflammation by reducing dsDNA release and oxidative stress. This was concomitant with the restoration of the intestinal barrier and modulation of the immune microenvironment. This work suggests the promise of the microalgae-carrying nanomedicine strategy for treatment of intestinal diseases, emphasizing its potential in addressing chemotherapy-induced gastrointestinal complications.

Interfacial modular assemblies of versatile polyphenols have attracted widespread interest in surface and materials engineering. In this study, natural polyphenol (tannic acid, TA) and nobiletin (NOB) can directly form binary carrier-free spherical nanoparticles (NT NPs) through synergistically driven by a variety of interactions (such as hydrogen bonding, oxidative reactions, etc.). The synthesis involves polyphenolic deposition on hydrophobic NOB nanoaggregates, followed by in situ oxidative self-polymerization. Interestingly, the assembled NT NPs exhibit controllable and dynamic changes in particle size during the initial stage. Ultimately, uniform and spherical NT NPs appear stable, with high loading capability, enabling incorporated NOB to preserve their function. Furthermore, in vitro evaluations demonstrate that the rational combination of polyphenol module and NOB can induce apoptosis and inhibit tumor metastasis for both lung cancer H1299 and human fibrosarcoma HT1080 cell lines. Notably, the optimized NT48 NPs were then verified in vivo experiments to achieve a promising synergistic anti-tumor efficacy. These findings not only provide new opportunities for the streamlined and sensible engineering of future polyphenol-based biomaterials, but also open up new prospects for the design of small-molecule nature phytochemicals.

The recent commercialization of gene products has sparked significant interest in gene therapy, necessitating efficient and precise gene delivery via various vectors. Currently, viral vectors and lipid-based nanocarriers are the predominant choices and have been extensively investigated and reviewed. Beyond these vectors, polymeric nanocarriers also hold the promise in therapeutic gene delivery owing to their versatile functionalities, such as improving the stability, cellar uptake and endosomal escape of nucleic acid drugs, along with precise delivery to targeted tissues. This review presents a brief overview of the status quo of the emerging polymeric nanocarriers for therapeutic gene delivery, focusing on key cationic polymers, nanocarrier types, and preparation methods. It also highlights targeted diseases, strategies to improve delivery efficiency, and potential future directions in this research area. The review is hoped to inspire the development, optimization, and clinical translation of highly efficient polymeric nanocarriers for therapeutic gene delivery.

A structural conjugate (HOC) of polysaccharide, hyaluronic acid (HA) with different ratios of oleic acid (OA) via cystamine (CYS) linker as a new ocular biomaterial was developed. The HOCs with controlled degrees of substitution of OA (4.6 %, 8.3 % and 12.2 %) were synthesized to form self-assembled HA-CYS-OA nanoparticles (HONs, HON1, HON2, HON3). A poorly water-soluble cyclosporine A (CsA) to be used for the treatment of multifactorial dry eye disease (DED) was chosen as model drug. CsA-loaded HONs exhibited improved solution transparency via solubilizing capacity of HON, and increased in vitro drug permeation compared to Restasis®. The physicochemical properties of CsA-loaded HONs such as nano behaviors, solution transparency, drug release, drug permeation and ocular cytocompatibility were highly variable according to the ratios of OA substitution. Interestingly, this CsA-loaded HON1 as optimal ocular nanoformulation showed markedly augmented macrophage polarization into the M2 phenotype, downregulated the expression of proinflammatory cytokines levels in LPS-induced M1 macrophage, and effectively inhibited VEGF-induced endothelial cell proliferation and capillary-like tube formation by the synergistic effect of CsA and HON1 containing OA at the same time. Collectively, the current fatty acid conjugated to HA, named fattigation platform, providing the roles and physicochemical properties via structural features of HA could be a promising co-delivery strategy of drug and fatty acid for DED and other ophthalmic disease treatments.

Herpes simplex virus thymidine kinase (HSVtk) gene therapy is a promising strategy for glioblastoma therapy. However, delivery of plasmid DNA (pDNA) encoding HSVtk into the brain by systemic administration is a challenge since pDNA can hardly penetrate the blood-brain barrier. In this study, an exosome-membrane (EM) and polymer-based hybrid complex was developed for systemic delivery of pDNA into the brain. Histidine/arginine-linked polyamidoamine (PHR) was used as a carrier. PHR binds to pDNA by electrostatic interaction. The pDNA/PHR complex was mixed with EM and subjected to extrusion to produce pDNA/PHR-EM hybrid complex. For glioblastoma targeting, T7 peptide was attached to the pDNA/PHR-EM complex. Both pDNA/PHR-EM and T7-decorated pDNA/PHR-EM (pDNA/PHR-EM-T7) had a surface charge of –5 mV and a size of 280 nm. Transfection assays indicated that pDNA/PHR-EM-T7 enhanced the transfection to C6 cells compared with pDNA/PHR-EM. Intravenous administration of pHSVtk/PHR-EM-T7 showed that pHSVtk/PHR-EM and pHSVtk/PHR-EM-T7 delivered pHSVtk more efficiently than pHSVtk/lipofectamine and pHSVtk/PHR into glioblastoma in vivo. pHSVtk/PHR-EM-T7 had higher delivery efficiency than pHSVtk/PHR-EM. As a result, the HSVtk expression and apoptosis levels in the tumors of the pHSVtk/PHR-EM-T7 group were higher than those of the other control groups. Therefore, the pDNA/PHR-EM-T7 hybrid complex is a useful carrier for systemic delivery of pHSVtk to glioblastoma.
单纯疱疹病毒胸苷激酶（HSVtk）基因治疗是一种很有前途的胶质母细胞瘤治疗策略。然而，编码HSVtk的质粒DNA （pDNA）通过全身给药进入大脑是一个挑战，因为pDNA很难穿透血脑屏障。在这项研究中，开发了一种外泌体-膜（EM）和基于聚合物的杂交复合物，用于将pDNA全身递送到大脑中。以组氨酸/精氨酸连接聚酰胺胺（PHR）为载体。PHR通过静电相互作用与pDNA结合。将pDNA/PHR配合物与EM混合，挤压得到pDNA/PHR-EM杂化配合物。针对胶质母细胞瘤，T7肽被附着在pDNA/ phrr - em复合物上。pDNA/PHR-EM和t7修饰的pDNA/PHR-EM （pDNA/PHR-EM- t7）表面电荷均为-5 mV，尺寸为280 nm。转染实验表明，与pDNA/PHR-EM相比，pDNA/PHR-EM- t7对C6细胞的转染增强。静脉给药pHSVtk/PHR- em - t7显示pHSVtk/PHR- em和pHSVtk/PHR- em - t7在体内比pHSVtk/脂质体和pHSVtk/PHR更有效地将pHSVtk输送到胶质母细胞瘤中。pHSVtk/PHR-EM- t7的输送效率高于pHSVtk/PHR-EM。结果显示，pHSVtk/ phrr - em - t7组肿瘤中HSVtk的表达和凋亡水平均高于其他对照组。因此，pDNA/ phrr - em - t7杂交复合体是将pHSVtk系统递送至胶质母细胞瘤的有用载体。

In clinical settings, regenerating critical-sized calvarial bone defects presents substantial problems owing to the intricacy of surgical methods, restricted bone growth medications, and a scarcity of commercial bone grafts. To treat this life-threatening issue, improved biofunctional grafts capable of properly healing critical-sized bone defects are required. In this study, we effectively created anti-fracture hydrogel systems using spongy-like metal-organic (magnesium-phosphate) coordinated chitosan-modified injectable hydrogels (CPMg) loaded with a bioinspired neobavaisoflavone (NBF) component. The CPMg-NBF hydrogels showed outstanding anti-fracture capabilities during compression testing and retained exceptional mechanical stability even after 28 d of immersion in phosphate-buffered saline. They also demonstrated prolonged and stable release profiles of Mg2+ and NBF. Importantly, CPMg-NBF hydrogels revealed robust biphasic mineralization and were non-toxic to MC3T3-E1 cells. To better understand the underlying mechanism of Mg2+ and NBF component, as well as their synergistic effect on osteogenesis, we investigated the expression of key osteogenic proteins in the p38 MAPK and NOTCH pathways. Our results showed that CPMg-NBF hydrogels greatly increased the expression of osteogenic proteins (Runx2, OCN, OPN, BMPS and ALP). In vivo experiments showed that the implantation of CPMg-NBF hydrogels resulted in a significant increase in new bone growth within critical-sized calvarial defects. Based on these findings, we expect that the CPMg-NBF supramolecular hydrogel has tremendous promise for use as a therapeutic biomaterial for treating critical-sized calvarial defects.

Our results showed that CPMg-NBF hydrogels greatly increased the expression of osteogenic proteins (Runx2, OCN, OPN, BMPS and ALP). <em>In vivo</em> experiments showed that the implantation of CPMg-NBF hydrogels resulted in a significant increase in new bone growth within critical-sized calvarial defects. Based on these findings, we expect that the CPMg-NBF supramolecular hydrogel has tremendous promise for use as a therapeutic biomaterial for treating critical-sized calvarial defects.</div></div>","PeriodicalId":8539,"journal":{"name":"Asian Journal of Pharmaceutical Sciences","volume":"20 1","pages":"Article 100988"},"PeriodicalIF":10.7,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143102272","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}

A new type of amphiphiles bearing macrocycle such as cucurbit[7]uril (CB[7]) spontaneously forms a nanomaterial in water, specifically vesicles (tACB[7] vesicles) with a positive surface charge, verified through various analytical techniques including TIRF, DLS and TEM. Functional validation not only reveals the accessibility of the CB[7] portal on these vesicles allowing CB[7]-based host-guest interactions with various functional guest molecules such as fluorescein isothiocyanate conjugated adamantylammonium and spermine (FITC-AdA and FITC-SPM, respectively) using confocal laser scanning microscopy, but also showcases the effective internalization of tACB[7] vesicles into cancer cells with the anticancer drug oxaliplatin (OxPt), as a guest to CB[7], through in vitro cell experiments. Hence, this study provides a blueprint to impart amphiphilic properties to CB[7] through synthetic design and highlights the potential of CB[7] derivatives as a new class of unconventional amphiphiles self-assembling into functional nanomaterials for advanced drug delivery.
