Various reproductive toxicities of PS-NPs have been reported, however, information regarding the effects of PS-NPs exposure during pregnancy on offspring development and the underlying mechanisms remains limited. In this study, pregnant mice were orally administered PS-NPs (approximately 100 nm in diameter) at different concentrations (1, 10, and 100 mg/kg/day) for 17.5 consecutive days, from gestational day (GD) 0.5 to GD 17.5. The relevant samples were collected on GD 18.5 to investigate the intergenerational effects. The results indicated that PS-NPs induced placental injury and metabolic abnormalities, leading to adverse pregnancy outcomes. Specifically, PS-NPs exposure observably reduced the levels of nicotinamide (NAM) and nicotinamide adenine dinucleotide (NAD<sup>+</sup>) in the placenta, resulting in decreased ATP production, increased oxidative stress and ferroptosis. Meanwhile, PS-NPs disrupted the maternal gut microbiome, specifically manifested as a reduction in Lactobacillus levels and abundances of norank_f_Muribaculaceae, Turicibacter, Alloprevotella, Parabacteroides and Ruminococcus. Fecal microbial transplant (FMT) experiments demonstrated that the microbiota from PS-NPs-administered pregnant mice could similarly induce intestinal barrier damages and placental injury. Treatment with NAM effectively mitigated disruptions in placental metabolism and reversed the adverse pregnancy outcomes caused by PS-NPs. These findings highlight the novel role of the gut microbiota in PS-NPs-induced placental injury and adverse pregnancy outcomes, and suggest that NAM could serve as a promising preventative strategy against this intergenerational damage caused by PS-NPs.</p>","PeriodicalId":16383,"journal":{"name":"Journal of Nanobiotechnology","volume":"23 1","pages":"561"},"PeriodicalIF":12.6,"publicationDate":"2025-08-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12341275/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144835349","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Pre-formation EV loading (i.e., during EV biogenesis), offers advantages compared to post-formation loading (i.e., after EV isolation), as EV integrity and composition are minimally perturbed. Pre-formation EV loading is primarily achieved through the genetic engineering of the producer cell, which is time consuming and not very flexible regarding the types of molecules that can be incorporated into EVs. In this work, we investigated the possibility of loading cargo molecules into EVs by delivering the cargo directly into the cytosol of the producer cells, which can subsequently be encapsulated into EVs as they are formed. For the cytosolic delivery of cargo molecules, we evaluated the use of photoporation. This membrane disruption technology has been demonstrated to successfully deliver a broad range of cargo molecules into virtually any cell type, while minimally impacting the cell's normal functioning and homeostasis. As a proof-of-concept, we delivered fluorescently labeled dextran macromolecules and anti-EGFP nanobodies into HEK293T cells genetically engineered with gag-EGFP fusion proteins, which are shuttled into EVs. Colocalization of cargo and EGFP fluorescence in secreted EVs can then serve as a convenient readout for successful EV loading. We established that photoporation had minimal impact on EV characteristics such as concentration, size, zeta potential and the enrichment of EV tetraspanin membrane surface molecules. We found that using EGFP-targeted nanobodies resulted in up to 53% loaded EVs (relative to the amount of EGFP EVs), while non-targeted dextran molecules produced on average 12% loaded EVs (relative to the amount of EGFP EVs).
