However, the conventional PTT is suffering from restrictions of heat resistance of tumor cells (<em>e.g.</em> the overexpression of heat shock proteins, HSPs) and adverse effects to normal cells. To break the shackles, herein, a hypoxia-responsive theranostic nanoplatform (GA/BN LIP) was designed for achieving synergistic chemotherapy, photothermal therapy (PTT), and photodynamic therapy (PDT) through overcoming heat-shock response, while enabling fluorescence tracing. The GA/BN LIP consisted of a hypoxia-responsive liposomal material (DSPE-AZO-PEG) as the shell, surface-functionalized with cRGD peptides targeted binding to integrin α<sub>V</sub>β<sub>3</sub> receptor expressed in tumors. The GA/BN LIP co-delivered gambogic acid (GA) as HSP90 inhibitor and hypoxia-responsive photosensitizer Bcy-NO<sub>2</sub>. After GA/BN LIP entering tumor cells by integrin α<sub>V</sub>β<sub>3</sub> receptor-mediated endocytosis, drugs were specifically released in response to hypoxic conditions due to lysis of liposomes. GA not only directly killed tumor cells to realize chemotherapy, but also sensitized tumor cells to PTT by downregulating HSP90 protein expression, meantime Bcy-NO<sub>2</sub> targeted mitochondria for combined PTT and PDT. Intriguingly, the reduction of Bcy-NO<sub>2</sub> by nitroreductase (NTR) resulted in the restoration of fluorescence, achieving real-time monitoring of the theranostic process in live cells. In conclusion, this theranostic system, designed to target the hypoxic tumor microenvironment, utilized a sensitization mechanism to enhance the synergistic effects of chemo/PTT/PDT therapy, resulting in improved antitumor efficacy in both <em>in vitro</em> and <em>in vivo</em> studies.</div></div>","PeriodicalId":19050,"journal":{"name":"Nanomedicine : nanotechnology, biology, and medicine","volume":"66 ","pages":"Article 102816"},"PeriodicalIF":4.2,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143772907","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

ExoACP showed enhanced penetration in brain microvascular endothelial cells, with a 7.20-fold increase in uptake. In the ADR model, ExoACP-Los exhibited anti-inflammatory and anti-fibrotic effects by downregulating the renin-angiotensin system, reducing extracellular matrix deposition by nearly half.

This study investigated whether subcutaneous (s.c.) administration of gold nanoparticles conjugated with ovalbumin (AuNPs@OVA) could serve as an effective adjuvant in oral tolerance and promote ear lesion repair in mice. Male Swiss mice received a 5-day oral OVA treatment, followed by s.c. injections of AuNPs@OVA at the tail base 7 days later, with a secondary injection administered 20 days after the initial dose. Lesions were created on one ear during the primary injection. Transmission electron microscopy (TEM) confirmed a spherical morphology of the AuNPs, with an average diameter of approximately 6.84 nm. The findings demonstrated that AuNPs@OVA injections enhanced IgG1, IgG2a, and total anti-OVA antibody levels in non-tolerant mice. Immunization also increased leukocyte levels at the injection site. In OVA-tolerant mice, AuNPs@OVA elevated the percentage of TBET-expressing cells in the caudal lymph nodes but not in the spleen. Histological analysis revealed improved ear tissue remodeling in OVA-tolerant mice treated with AuNPs@OVA compared to other groups.
