However, there is still demand for effective and safe anti-inflammatory therapies. Here we report a potent anti-inflammatory macromolecular therapy named HPL, created by conjugating polyethylene glycol and luminol onto a multivalent and hydrolysable cyclic structure. Leveraging its amphiphilic nature, HPL can spontaneously self-assemble into micelles capable of targeting inflamed tissues and localizing in inflammatory cells. In mice with acute lung, kidney and liver injuries, as well as endotoxaemia, HPL shows anti-inflammatory effects that rivals or surpasses those of two commonly used anti-inflammatory drugs. HPL micelles can act as bioactive and inflammation-responsive carriers for site-specific delivery to release anti-inflammatory drugs. Mechanistically, HPL exerts its anti-inflammatory activity mainly by inhibiting the IL-6/JAK2/STAT3 signalling pathway. HPL shows favourable safety profiles in mice at doses at least 5-fold higher than those used in therapeutic studies. These findings suggest that HPL holds great promise as a highly potent, cost-effective and safe JAK2 inhibitor for treating various diseases associated with inflammation.","PeriodicalId":19063,"journal":{"name":"Nature Biomedical Engineering","volume":"16 1","pages":""},"PeriodicalIF":28.1,"publicationDate":"2025-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145311252","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}

Traditional needle biopsies, limited in tissue sampling, often lead to inaccurate assessments due to intratumoural heterogeneity. Here, to address this, we introduce the deep-learning-based HER2 multimodal alignment and prediction (MAP) model, which leverages pretreatment multimodal breast cancer images for a more comprehensive reflection of tumour characteristics and provides more accurate HER2 status prediction. We develop patient response MAP models to demonstrate the HER2 prediction performance of our model compared with needle biopsies from patients receiving neoadjuvant therapy. A large-scale multimodal breast cancer dataset from 4 centres, consisting of 14,472 images from 6,991 cases, is adopted in this study, and the results consistently demonstrate the superiority of our HER2 MAP model in predicting patient response. These findings highlight the substantial advantages of our HER2 predictions. Our study provides physicians with a crucial tool for informed clinical decisions and treatment plans, aiming to improve outcomes in patients with breast cancer.","PeriodicalId":19063,"journal":{"name":"Nature Biomedical Engineering","volume":"19 1","pages":""},"PeriodicalIF":28.1,"publicationDate":"2025-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145311454","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}

Here we identify the RNA binding protein La-related protein 4 (LARP4) as an important checkpoint regulator of quiescence exit in naive CD4+ T cells. Conditional knockout of LARP4 in naive CD4+ T cells leads to an enhanced quiescence state and/or dampened quiescence exit due to altered stability of several messenger RNAs important for T-cell activation. The differentiation of naive CD4+ T cells into helper T-cell subsets is also impaired after conditional knockout, leading to ameliorated autoimmune and allergic responses. Lastly, we design a peptide inhibitor of LARP4 (LIPEP), and treatment with LIPEP could perfectly mimic LARP4 deficiency and alleviate the severity of autoimmune and allergic diseases in the corresponding mouse models. Our study reveals a link between RNA stability and CD4+ T-cell homeostasis/adaptive activation, highlighting the potential of LARP4 as a preventative and therapeutic target for autoimmune and allergic diseases although at quite high doses.","PeriodicalId":19063,"journal":{"name":"Nature Biomedical Engineering","volume":"20 1","pages":""},"PeriodicalIF":28.1,"publicationDate":"2025-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145305586","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}

We discuss innovations in LNP chemistry and bioengineering, and exploiting synthetic biology to tailor the cellular expression of the mRNA cargo, including the use of microRNA target sites. We also review how modifications to the encoded protein can be used to control stability and subcellular localization of the payload. Lastly, we discuss how these techniques and strategies can accelerate the clinical translation of RNA-LNP drugs and improve therapeutic outcomes.
