The ineffective treatment of GBM can be partially attributed to the existence of the blood-brain barrier (BBB). Lipids, which constitute over half the weight of the brain and play a vital role in brain tumor biology, can be transported to the brain in the form of lysophosphatidylcholines (LPCs) via specific LPC transporters at the BBB. We hypothesize that LPC analogs could be used as carriers for drug delivery to tumors in the brain. To test this hypothesis, we synthesized and screened a collection of LPC analogs, among which LPC analog 3 (A3), featuring a glycerophosphorylcholine (GPC) headgroup and a 15‑carbon tail, exhibited a marked ability to penetrate brain tumors. We characterized A3 as a carrier for drug delivery to brain tumors by using Doxorubicin (Dox) as the therapeutic payload and found that the A3-Dox conjugate with a cathepsin B-cleavable linker has a great ability to accumulate in brain tumors, leading to effective treatment of GBM without inducing significant cytotoxicity.

However, the intricate tumor microenvironment (TME), characterized by a rigid extracellular matrix (ECM) and robust immunosuppressive environment, presents substantial hurdles to the effectiveness of cancer immunotherapy. Thus, cancer-associated fibroblasts (CAFs), the most abundant stromal cells that mediate ECM remodeling and participate in immune suppression, represent promising therapeutic targets for combination immunotherapy. In this study, by using and analyzing single-cell RNA-sequencing (scRNA-seq) in the public datasets, we have identified the elevated expression of glucose transporter 1 (GLUT1) in activated CAF subgroups within tumor sites compared to normal tissues. Moreover, the recent literature has also demonstrated that CAFs undergoing high metabolic levels have been identified to show a better response to immunotherapy. Furthermore, extracellular vesicles (EVs) secreted by CAFs remain unexplored, and their role in drug transport systems and targeting efficiency towards tumorous cells remains uninvestigated. Herein, we identified the elevated expression of glucose transporter 1 (GLUT1) as a prognostic indicator for cancer associated with poor prognosis and investigated the vulnerability of lung tumor cell lines and CAFs to pharmacological GLUT1 inhibition with BAY-876. Based on the possibility of targeting the intrinsic TME-associated metabolism by GLUT1 inhibition, we have firstly employed CAFs-derived extracellular vesicles (cEVs) as a carrier for targeted delivery of BAY-876 into GLUT1-high CAFs and tumor cells. The cEV-BAY-876 (cEV<img>B6) treatment significantly resulted in glucose-rich, low-lactate TME, reversed the activated CAFs phenotype, enabled stromal reprogramming, decreased ECM stiffness and enhanced the infiltration of CD3 + CD8+ T cells in tumor core, thereby achieving an excellent anti-tumor efficiency. Moreover, cEV-B6 treatment synergized anti-programmed death ligand 1 (antiPD-L1) to reinvigorate the exhausted lymphocytes and exerted strong anticancer effects against mice lung tumors. Our study provides the first evidence that tumor stroma-specific therapies by targeting glucose metabolism present a promising strategy of remodeling the extracellular matrix to reverse CAFs into normal type and potentiate cytotoxic T lymphocytes (CTLs) infiltration thereby improving anticancer immunotherapy.</div></div>","PeriodicalId":15450,"journal":{"name":"Journal of Controlled Release","volume":"385 ","pages":"Article 113998"},"PeriodicalIF":10.5,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144521331","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}
