This study evaluates the therapeutic potential of itacitinib (ITA) encapsulated in wheat germ agglutinin-functionalized nanoparticles (WGA/F127/PNPs) to target and inhibit the JAK-STAT pathway in slan+ monocytes.Methods: We prepared ITA-loaded WGA/F127/PNPs and analyzed their binding and internalization in various leukocyte subsets using flow cytometry, focusing on slan+ and slan- monocytes. Further, peripheral blood samples from healthy controls (n = 37) and SLE patients (n = 50) were used to assess slan+ monocyte phenotypes. Co-cultures of slan+ and slan- monocytes stimulated with LPS revealed that slan+ monocytes significantly increased HLA-DR expression.Results: Results showed that slan+ monocytes from SLE patients were reduced compared to healthy controls (p < 0.001) and that slan+ monocytes effectively internalized WGA/F127/PNPs, unlike slan- cells. ITA-loaded nanoparticles decreased HLA-DR, CD69, and CD86 expression, STAT1 phosphorylation, and cytokine production in IFN-γ-stimulated slan+ monocytes. Findings support WGA/F127/PNPs as a promising drug delivery system for targeting slan+ monocytes, providing new therapeutic potential for SLE.Conclusion: ITA-loaded WGA/F127/PNPs effectively target and suppress pro-inflammatory slan+ monocytes, presenting a promising, cell-specific therapeutic approach for managing systemic lupus erythematosus and related autoimmune disorders.","PeriodicalId":74240,"journal":{"name":"Nanomedicine (London, England)","volume":"20 10","pages":"1113-1126"},"PeriodicalIF":0.0,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12068337/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144030714","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Plasmid (IL-4, IL-10, and TGF-β1)-encapsulated PLGA NPs (PLGA@IL-4, PLGA@IL-10, and PLGA@TGF-β1) were synthesized and characterized for size, zeta potential, cellular toxicity, and cellular uptake. The analgesic effect of anti-inflammatory gene delivery using PLGA NPs was then assessed in a mouse model of neuropathic pain.Results: Gene delivery of IL-4, IL-10, and TGF-β1 showed a significant anti-inflammatory effect in LPS-treated cells and IL-4 strongly promoted microglia M2 polarization in vitro. PLGA NPs successfully delivered the anti-inflammatory cytokine-coding genes into mouse spinal cord cells, specifically targeting microglia. PLGA@IL-4, PLGA@IL-10, and PLGA@TGF-β1 NPs produced analgesic effects in a SNT-induced mouse neuropathic pain model.

Delivery to the lungs offers several compelling advantages for mRNA delivery. The lungs are one of the most vascularized organs in the body, which provides an extensive surface area that can facilitate efficient drug transport. Local delivery to the lungs bypasses gastrointestinal degradation, potentially enhancing therapeutic efficacy. In addition, the extensive capillary network of the lungs provides an ideal target for systemic delivery. However, developing effective mRNA therapies for the lungs presents significant challenges. The complex anatomy of the lungs and the body's immune response to foreign particles create barriers to delivery. This review discusses key approaches for overcoming these challenges and improving mRNA delivery to the lungs. It examines both local and systemic delivery strategies aimed at improving lung delivery while mitigating off-target effects. Although substantial progress has been made in lung-targeted mRNA therapies, challenges remain in optimizing cellular uptake and achieving therapeutic efficacy within pulmonary tissues. The continued refinement of delivery strategies that enhance lung-specific targeting while minimizing degradation is critical for the clinical success of mRNA-based pulmonary therapies.","PeriodicalId":74240,"journal":{"name":"Nanomedicine (London, England)","volume":" ","pages":"1043-1069"},"PeriodicalIF":0.0,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12051540/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143797356","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Notably, breast cancer detection has been identified as a key application for this modality; however, inherent contrast in tissue dielectric properties may not always be sufficient to allow imaging/sensing. Nanoparticles could provide the necessary enhancement, due to their effect on the dielectric properties of the target tissue and their ability to accumulate in tumours. This study aims to prepare novel zinc ferrites ZnFe2O4 nanoparticles and investigate their potential as contrast agents for MW imaging/sensing.Method: Zinc ferrite nanoparticles were synthesized by thermal decomopositon and phase transferred using a co-polymer to improve biocompatibility. Dielectric properties were evaluated using the co-axial probe technique, progressing to ex vivo and in vivo studies in a triple-negative breast cancer xenograft mouse model.Results: Tumours regions injected subcutaneously with nanoparticles in vivo showed an increased dielectric constant of up to 49% compared with approximately 3% ex vivo. Significant increases in conductivity were also observed indicating potential application of the particles as MW hyperthermia sensitizers.Conclusions: Crucially, this study presents the first in vivo evaluation of nanoparticles as contrast agents for MW imaging/sensing.

Nanomaterials provide a potential solution for neurotoxin neutralization in NDs due to their unique physicochemical and biological properties. This review summarizes recent advancements in nanomaterial-based approaches to neurotoxin neutralization in NDs, highlighting the diverse design principles and mechanisms of action. We also discuss the critical role of targeted delivery to optimize neutralization efficiency and the advantages of combining different neutralization mechanisms or introducing other therapeutic components to exert the synergistic effects.

Glutathione, a thiol tripeptide plays a paradoxical role in cancer as intracellular glutathione (GSH) are voracious scavengers of free radicals produced by chemotherapy, generation of reactive oxygen species (ROS) and reactive nitrogen species (RNS). Cancer cells show Warburg effect, wherein the intracellular GSH levels are exceptionally enhanced to overcome the oxidative stress created by ROS/RNS production or by the other free radicals generated as side products of intracellular redox reactions. Therefore, redox resetting is essential to maintain the redox homeostasis for cell survival and their proliferation and trigger escalation of GSH levels.

The deliberate surface treatment of AuNPs has the potential to overcome this inherent limitation.Methods: To probe interactions between surface treated AuNPs in blood plasma, we employed a size-exclusion chromatography (SEC)-based metallomics tool together with transmission electron microscopy (TEM).Results: After the addition of citrate capped AuNPs to plasma, its metallomics analysis revealed a >670 kDa Au species, which TEM analysis identified as AuNP-plasma protein aggregates. To ameliorate the formation of the latter, the surface of citrate capped AuNPs was modified with dithiothreitol (DTT), meso 2,3-dimercaptosuccinic acid (DMSA), or 2,3 dimercapto-1-propionesulfonic acid (DMPS) and the effect of this surface treatment was probed after the addition of these modified AuNPs to rabbit plasma. The results for DMSA/DMPS-treated AuNPs revealed that the tight binding of these dithiols more significantly reduced protein corona formation compared to DTT-AuNPs implying that the surface treatment of AuNPs with DMSA or DMPS is a feasible strategy to control protein corona formation and thus their aggregation in plasma.Conclusions: The AuNP-based delivery of immobilized drugs using targeting sequences to cancer tissues can be enhanced by their surface treatment with DMSA or DMPS. Since dithiols left over after the AuNP surface treatment mobilized iron from plasma metalloproteins, excess dithiols must be removed before injecting patients.","PeriodicalId":74240,"journal":{"name":"Nanomedicine (London, England)","volume":"20 10","pages":"1127-1138"},"PeriodicalIF":0.0,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12068335/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144060066","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
