Probiotic-derived nanovesicles show immense potential as novel cell-free nanomedicines; however, the lack of clarity regarding their precise mechanism of action in bone tissue regeneration restricts their clinical application. This study utilized a ligature-induced periodontitis mouse model (in vivo) and in vitro models, including macrophage functional assays and macrophage-osteoblast co-culture systems, to investigate the therapeutic effects and mechanism of <i>Lactobacillus rhamnosus</i> GG-derived extracellular vesicles (LEVs). In the periodontitis mouse model, LEVs effectively mitigated inflammatory infiltration and promoted alveolar bone regeneration. In vitro studies demonstrated that LEVs enhance macrophage polarization toward a reparative (M2) phenotype. Mechanistically, we identify LEVs as bioactive nanocarriers that deliver tryptophan metabolites. Upon internalization by macrophages, these metabolites trigger a critical metabolic and phenotypic shift by activating the aryl hydrocarbon receptor (AhR). Further research revealed that this effect is mediated by the AhR/NAD(P)H:quinone oxidoreductase 1 (NQO1)/carnitine palmitoyltransferase 1A (CPT1A) signaling axis: AhR transcriptionally up-regulates NQO1, which critically inhibits the 26S proteasome-mediated degradation of CPT1A. The resulting sustained CPT1A expression dramatically boosts fatty acid oxidation, which is essential for driving the reparative macrophage phenotype.

However, targeted therapeutics for renal lipid deposition are scarce. This study fills this research gap: first, clinical database analyses identified a positive correlation between up-regulated rho-associated coiled-coil protein kinase 1 (ROCK1) expression in renal tubules and progressive renal function deterioration in DKD patients, a finding recapitulated in DKD mouse models, which also exhibited renal tubular ROCK1 up-regulation and concomitant lipid accumulation; second, molecular docking, surface plasmon resonance, and cellular thermal shift assay confirm that the natural molecule stigmasterol (ST) binds to ROCK1 and inhibits its expression with a dose-dependent trend; and, third, in vivo and in vitro experiments demonstrate that ST alleviates lipid accumulation, mitochondrial damage, and renal fibrosis in DKD via the ROCK1/p38 mitogen-activated protein kinase/peroxisome proliferator-activated receptor α axis. In conclusion, ST exerts direct renoprotective effects by regulating the ROCK1 pathway to improve renal lipid metabolism, reduce mitochondrial damage, and inhibit fibrosis, highlighting its potential as a novel ROCK1 inhibitor. This study identifies ST as a candidate for targeted intervention in DKD-related lipid metabolism, validates ROCK1 as a therapeutic target, provides an experimental basis for the DKD treatment strategy of \"targeting ROCK1 to synergistically improve lipid metabolism and mitochondrial function\", and opens new avenues for natural products in metabolism-related nephropathies.</p>","PeriodicalId":93902,"journal":{"name":"Biomaterials research","volume":"30 ","pages":"0389"},"PeriodicalIF":9.8,"publicationDate":"2026-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13376380/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148581562","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}
