The framework was evaluated using PEGylated gold nanoparticles (AuNPs) spanning a range of particle sizes and incorporated empirical size-parameter relationships to enable in vitro<em>-</em>in vivo translational analysis. Model simulations suggested that transcytosis-mediated processes account for the majority of tumor AuNP accumulation under the modeled physiological conditions (99.0 %, 95 % CI: 94.7 %–99.8 %), whereas passive diffusion contributed a smaller fraction under most conditions examined. Dose-dependent analysis further indicated a capacity-limited tumor accumulation behavior, with a threshold around 18 mg, beyond which increasing the dose to 100 mg resulted in only a modest (∼15 %) increase in tumor accumulation. Sensitivity analyses indicated that systemic exposure and endothelial intracellular trafficking behavior are key determinants influencing tumor delivery, whereas enhanced intracellular sequestration consistently reduced tumor accumulation across dose levels. Overall, the proposed m-PBPK framework provides mechanistically interpretable, proof-of-concept insights into nanoparticle tumor delivery, supporting quantitative assessment of transcytosis efficiency and dose-dependent accumulation behavior for hypothesis generation in nanomedicine development.</div></div>","PeriodicalId":15450,"journal":{"name":"Journal of Controlled Release","volume":"392 ","pages":"Article 114684"},"PeriodicalIF":11.5,"publicationDate":"2026-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146109924","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This phenomenon is largely the result of the mononuclear phagocytic system (MPS), a class of phagocytic cells responsible for native immune response and toxin clearance within the body. One strategy to overcome NP clearance by the MPS is the use of phagocytic modulating pre-treatments to intentionally and temporarily alter the phagocytic behavior of macrophages such that sequentially administered therapeutic NPs can be delivered to extrahepatic and extrasplenic tissues. Here, we explore the use cargo-free poly(lactic-<em>co</em>-glycolic acid) (PLGA) “decoy” NPs as pre-treatments for phagocytic evasion of sequentially administered therapeutic NPs. Analysis via flow cytometry and fluorescence microscopy reveal that cargo-free PLGA NPs significantly decrease uptake of subsequently administered therapeutic NPs by macrophages. Specifically, we conclude that variables such as size, surfactant composition, and timing of pre-treatment influence the behavior of cargo-free PLGA decoy NPs in modulating phagocytic activity of macrophages. In <em>in vivo</em> studies, we report decreased accumulation in the liver and increased deposition of therapeutic NPs in the lung with pre-administration of cargo-free decoy PLGA NPs.
