Here we show that intravenous injections of <i>IL-10</i> messenger RNA (mRNA) nanoparticles (<i>IL-10</i>-mRNA@NPs) induce potent immune surveillance across diverse preclinical tumour models and mitigate systemic toxicities. In particular, <i>IL-10</i>-mRNA@NPs sustain in situ IL-10 production within tumours, promoting substantial infiltration and proliferation of cytotoxic T cells, activation and maturation of dendritic cells, and an augmented expression of major histocompatibility complex class I molecules in immunosuppressive orthotopic early stage hepatocellular carcinoma tumours. Moreover, in mice with orthotopic middle-to-late-stage hepatocellular carcinoma tumours, combining <i>IL-10</i>-mRNA@NPs with immune checkpoint blockades results in 43% of mice showing complete tumour eradication and a sixfold increase in median survival compared with mice treated with immune checkpoint blockades alone. Furthermore, this combination induces long-lasting antitumour immune memory, conferring 100% protection against tumour rechallenges.

Here we show that LNPs’ hallmark feature, endosomal escape, which is necessary for RNA expression, also triggers inflammation by causing endosomal membrane damage. Large, irreparable, endosomal holes are recognized by cytosolic proteins called galectins, which regulate downstream inflammation. We find that inhibition of galectins abrogates LNP-associated inflammation, both in vitro and in vivo. Moreover, we show that a unique class of ionizable lipids can create smaller endosomal holes, reparable by the endosomal sorting complex required for transport (ESCRT) pathway. Such lipids can produce high expression from cargo messenger RNA with minimal inflammation. Finally, we show that both galectin inhibition or ESCRT-recruiting ionizable lipids allow for treatment of highly inflammatory disease models by therapeutic mRNAs. These strategies should lead to safer non-inflammatory LNPs that can be generally used to treat inflammatory diseases. Preventing endosomal damage sensing or using lipids that create reparable endosomal holes reduces inflammation caused by RNA-lipid nanoparticles while enabling high RNA expression.","PeriodicalId":18915,"journal":{"name":"Nature nanotechnology","volume":"20 9","pages":"1285-1297"},"PeriodicalIF":34.9,"publicationDate":"2025-08-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144813055","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

When exposed to a large excess of the cationic polymer polyethylenimine (PEI), the single saRNA molecules in solution reorganize from an extended to a globular organization, characterized by a high packing density, low polymer mass fraction and, consequently, a very small size of the polyplex nanoparticles of about 30 nm. This format of PEI-complexed saRNA exhibits enhanced biological activity in comparison with previously described saRNA/PEI formulations, both in vitro and in vivo. In vaccination models, relevant immune responses at lower doses are achieved, offering potential advantages for practical use. We found that the single PEI-complexed RNA molecules are also present in conventional formulations to some degree. The direct correlation between the single-molecule fraction with activity suggests that it is this format that predominantly contributes to activity in the different formulation types. Complexation is driven by mechanisms of self-assembly between oppositely charged polyelectrolytes, making this protocol broadly applicable to various cationic polymers and RNA constructs. With their small size and good stability in biofluids, these compacted RNA molecules are also promising for the systemic delivery of genetic material to compartments that are difficult to reach with larger particles. Single, self-amplifying RNA molecules condensed by an oppositely charged polyelectrolyte self-assemble into compact globular nanoparticles that can be used as vaccines to generate potent immunological responses at low doses.","PeriodicalId":18915,"journal":{"name":"Nature nanotechnology","volume":"20 9","pages":"1323-1331"},"PeriodicalIF":34.9,"publicationDate":"2025-08-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144813094","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Lipid nanoparticles (LNPs) efficiently encapsulate and protect mRNA, but non-specific cellular uptake may lead to off-target delivery and minimal delivery to target cells. Functionalizing LNPs with antibodies enables targeted mRNA delivery, but traditional modification techniques require complex conjugation and purification, which often reduces antibody affinity. Here we present a simple method for capturing antibodies in their optimal orientation on LNPs, without antibody modification or complex purification. This strategy uses an optimally oriented anti-Fc nanobody on the LNP surface to capture antibodies, resulting in protein expression levels more than 1,000 times higher than non-targeted LNPs and more than 8 times higher than conventional antibody functionalization techniques. These precisely targeted LNPs showed highly efficient in vivo targeting to T cells, with minimal delivery to other immune cells. This approach enables the rapid development of targeted LNPs and has the potential to broaden the use of mRNA therapies. A mix-and-go system enables the rapid prototyping of antibody formulations, allowing control of their orientation on the surface of LNPs for specific cell targeting, significantly improving the ex vivo and in vivo deliveries of mRNA.","PeriodicalId":18915,"journal":{"name":"Nature nanotechnology","volume":"20 9","pages":"1273-1284"},"PeriodicalIF":34.9,"publicationDate":"2025-08-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.comhttps://www.nature.com/articles/s41565-025-01954-9.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144770026","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Usually, the selectivity of molecular recognition is under thermodynamic control; however, when a higher fidelity is required, nature improves recognition selectivity by an error correction mechanism under an energy-dissipating kinetic-control regime. Here, exploiting DNA hybridization as a model, we present an abiotic example of an information ratchet mechanism that increases selectivity for the ‘correct’ duplex from 2:1 at equilibrium to 6:1 under energy-dissipating conditions. Structural asymmetry in the DNA strands introduces kinetic asymmetry in the reaction network, enabling enrichment under non-equilibrium conditions. We quantify the free-energy cost associated with enhanced selectivity using Shannon entropy formalism, finding that an increase in information of 0.33 bits is associated with at least 3.0 kJ mol<sup>−1</sup> of free energy. Moreover, the minimalistic structures of our error reduction system demonstrates that biomachinery is not necessary to increase molecular recognition fidelities above the thermodynamically expected values, thereby pointing a way towards solving Eigen’s paradox.</p>","PeriodicalId":18915,"journal":{"name":"Nature nanotechnology","volume":"151 1","pages":""},"PeriodicalIF":38.3,"publicationDate":"2025-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144756645","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
