For cancer therapeutic vaccines, it is critical to deliver circRNA to lymphoid tissues such as lymph nodes (LNs) and dendritic cells (DCs) and then elicit antigen-specific T cell responses. Lipid nanoparticles (LNPs) have shown great success for mRNA vaccines and may also have great potential as nanocarriers for circRNA vaccines. Here, we studied the impact of LNP composition on the efficiency of immune delivery, protein expression, and the T cell responses for circRNA vaccine. First, we used model mRNA and circRNA encoding firefly luciferase (mRNA-fLuc) to study protein expression and used two small circRNA vaccines to study T cell responses. We investigated a combination of six ionizable lipids, three helper lipids, and six different molar ratios of cholesterol and β-sitosterol for their impact on the physicochemical properties of RNA LNPs, <em>in vitro</em> DC transfection, <em>in vivo</em> protein expression in draining LNs, and antigen-specific T cell responses. Among these ionizable lipids, SM-102 was the most effective for DC transfection and enabling circRNA vaccines to elicit T cell responses. DOPE and β-sitosterol incorporation in LNPs resulted in efficient protein expression, albeit β-sitosterol incorporation appeared to be associated with reduced T cell response. Overall, circRNA was efficiently delivered to DCs and macrophages in mouse draining lymph nodes by LNPs of SM-102 (50 %), cholesterol (38.5 %), DOPE (10 %), and DMG-PEG2000 (1.5 %), resulting in the induction of potent antigen-specific CD8<sup>+</sup> T cell response in mice. These findings may provide insights into designing the compositions of LNPs as the carrier for circRNA therapeutics and vaccines.</div></div>","PeriodicalId":15450,"journal":{"name":"Journal of Controlled Release","volume":"381 ","pages":"Article 113617"},"PeriodicalIF":10.5,"publicationDate":"2025-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143635562","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}

Particularly for tumor treatment, this artificially manipulated cell surface engineering can achieve excellent anti-tumor effects by altering the cell membrane structure, influencing receptor clustering or interfering with relevant signal pathways. Of note, membrane-anchoring peptides play a key role in these processes. In this review, we focus on three main types of membrane-anchoring peptides, elaborating in detail on how their assembly regulation mechanisms influence the cell membrane remodeling effect, and further exert therapeutic effects on tumors.

Herein, an assembled mesenchymal stem cell (MSCs)-laden granular hydrogel (termed assembled GSD@FPs), loaded with basic fibroblast growth factor (bFGF) and platelet-derived growth factor (PDGF), is developed. This hydrogel is constructed through dynamic covalent cross-linking (<em>via</em> borate ester bonds) among dopamine-grafted gelatin methacrylamide (GelMA-DA), phenylborate-modified hyaluronic acid (HA-PBA), and epigallocatechin-3-gallate (EGCG), serving as multifunctional bulk building blocks for cell delivery and abdominal wall repair. The designed assembled granular hydrogels possess good rheological properties, self-healing, injectability, and tissue-adhesion properties. Detailed <em>in vitro</em> cell experiments are conducted, revealing that the GSD@FPs granular hydrogels can effectively promote cell proliferation, cell migration and angiogenesis. Furthermore, in abdominal wall defects, assembled GSD@FPs significantly accelerates the tissue healing process by simultaneously inhibiting the inflammatory response, promoting collagen deposition, and promoting cell proliferation and angiogenesis. Importantly, the assembled GSD@FPs granular hydrogels can also provide mechanical support and increase the thickness of regenerated tissue (1727.8 ± 169.6 μm for the control group, 3204.2 ± 278.5 μm for the assembled GSD@FPs group at 14 d).
