As expected, it extracted the primary fibroin and sericin proteins, but unexpectedly, the extract was dominated by sericin 3 and an 18.4 kDa protein with unknown function. We propose two possible functions: firstly, that it facilitates sericin 3 expression or secretion and secondly, that it acts as a “calcium chelator”, acting as a molecular trigger for fiber formation. In addition, analysis of the theoretical fractional charges of the primary silk proteins predicts that sericin 3 and fibrohexamerin (P25) transitions from negatively charged to neutral charge at the pH in the anterior silk gland, suggesting a previously unrecognized mechanism for regulating protein interactions during spinning.

Emerging evidence highlights the importance of coupled phenomena, including nanoconfinement, ionic and pH regulation, and hierarchical structural remodeling, in directing mineral formation. Silk fibroin (SF) is a versatile structural protein widely used in biomaterials due to its tunable mechanics, scalable processing into micro- and nanoscale constructs, controllable biodegradation, and ability to support cell infiltration and tissue integration, including in bone. However, despite its favorable biological properties, SF exhibits limited intrinsic self-mineralization in physiological fluids, restricting its mechanical reinforcement and osteogenic potential. In this study, we engineered SF scaffolds with controlled microstructure and anisotropy and incorporated bioactive inorganic phases, nano-hydroxyapatite (HA) or 45S5 bioactive glass (BG) to promote self-directed mineralization. Scaffolds were evaluated in simulated body fluid under static and dynamic conditions to assess mineral formation and distribution. Isotropic architectures supported more uniform, volumetric mineral integration, whereas anisotropic scaffolds promoted preferential surface mineral deposition. Incorporation of HA or BG significantly enhanced mineralization, leading to the formation of carbonate-substituted hydroxyapatite (CHA).

Using herbs as precursors to prepare CDs can preserve the \"multicomponent, multitarget\" characteristics of the crude herbs, enhance and transform their functions through nanoscale effects, offering unique advantages in biomedicine. Quantitative analysis of 121 entries reveals that herb-derived CDs typically exhibit particle sizes of 1−6 nm (mean ≈ 3.4 nm), quantum yields up to 0.67 (mean ≈ 0.11), and broad emission tunability (400−730 nm), with 51 reports including <em>in vivo</em> biosafety testing, all of which showed no obvious toxicity. Based on the latest advances in herb-derived CDs, this review focuses on precursor selection, pretreatment, and synthesis methods. Furthermore, it discusses their applications in biomedicine, bioimaging, and sensing in detail. Finally, a summary and outlook for this significant and promising field are provided.

However, most current preclinical and clinical efforts rely on non-targeted delivery systems, limiting their safety, therapeutic efficacy, and selectivity. To enhance the therapeutic index of RNA-based therapeutic systems, we report on the design of a novel Clec9A-targeted polymeric nanoparticle aimed at exploring strategies to enhance delivery toward CLEC9A-expressing immune cells as a proof of concept in the field of mRNA vaccination. We began by evaluating in silico the binding potential of the previously reported 12-amino-acid WH peptide, known for its high affinity to mouse Clec9A, the human ortholog. Using computational tools, we designed and screened truncated variants of the peptide and identified promising candidates with retained, or even enhanced, binding capacity to human Clec9A. These optimized short peptides were synthesized and covalently conjugated to our proprietary poly(beta-amino ester) (pBAE) polymers. We evaluated the impact of the conjugation site on receptor targeting by comparing terminal versus lateral chain attachment. We show that peptide orientation significantly influences transfection efficiency in human THP-1 cells, used as a monocytic robust in vitro model. Additionally, we computationally generated and validated shorter mutant peptide variants with improved Clec9A affinity over the original sequences. Our findings demonstrate that rationally engineered short peptides improve transfection in a human monocytic cell model, which is consistent with the proposed Clec9A-targeting strategy suggested by computational modeling. This strategy lays the groundwork for the next generation of targeted RNA-based (immune)therapeutics, offering improved selectivity and consequent therapeutic potential.</p>","PeriodicalId":8,"journal":{"name":"ACS Biomaterials Science & Engineering","volume":"12 11","pages":"6067–6078"},"PeriodicalIF":6.0,"publicationDate":"2026-11-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149100917","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
