Angew Chem Int Ed Engl 2024; 63:e202318544. [PMID: 38194267 DOI: 10.1002/anie.202318544] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/03/2023] [Revised: 12/30/2023] [Accepted: 01/09/2024] [Indexed: 01/10/2024]
Abstract
Antigen-presenting cells (APCs) play a crucial role in the anti-tumor immunity as they are responsible for capturing, processing, and presenting tumor antigens to T cells. However, their activation is often limited by the absence of adjuvants and the suppressive effects of immune checkpoints, such as CD47-SIRPα. Herein, we present a nanoadjuvant that is self-assembled from long RNA building blocks generated through rolling circle transcription (RCT) reaction and further modified with cationic liposomes. Owing to the high load of densely packed RNA, this nanoadjuvant could robustly activate RIG-I/MDA5 signaling in APCs, leading to the maturation of dendritic cells (DCs) and the polarization of tumor-associated macrophages (TAMs) toward an anti-tumor M1-like phenotype. In addition, with a well-designed template, the generated long RNA from RCT reaction includes two kinds of siRNA targeting both CD47 in tumor cells and SIRPα in APCs. This dual gene silencing results in efficient inhibition of the CD47-SIRPα checkpoint. Collectively, the robust activation of RIG-I/MDA5 signaling and efficient inhibition of CD47-SIRPα checkpoint enhance the phagocytic activity of APCs, which in turn promotes the cross-priming of effector T cells and the activation of anti-tumor immune responses. This study therefore provides a simple and robust RNA nanoadjuvant for cancer immunotherapy.

Biomaterials 2023; 299:122164. [PMID: 37229807 DOI: 10.1016/j.biomaterials.2023.122164] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/24/2023] [Revised: 04/29/2023] [Accepted: 05/15/2023] [Indexed: 05/27/2023]
Abstract
It is a challenging task to develop a contrast agent that not only provides excellent image contrast but also protects impaired kidneys from oxidative-related stress during angiography. Clinically approved iodinated CT contrast media are associated with potential renal toxicity, making it necessary to develop a renoprotective contrast agent. Here, we develop a CeO2 nanoparticles (NPs)-mediated three-in-one renoprotective imaging strategy, namely, i) renal clearable CeO2 NPs serve as a one-stone-two-birds antioxidative contrast agent, ii) low contrast media dose, and iii) spectral CT, for in vivo CT angiography (CTA). Benefiting from the merits of advanced sensitivity of spectral CT and K-edge energy of Cerium (Ce, 40.4 keV), an improved image quality of in vivo CTA is successfully achieved with a 10 times reduction of contrast agent dosage. In parallel, the sizes of CeO2 NPs and broad catalytic activities are suitable to be filtered via glomerulus thus directly alleviating the oxidative stress and the accompanying inflammatory injury of the kidney tubules. In addition, the low dosage of CeO2 NPs reduces the hypoperfusion stress of renal tubules induced by concentrated contrast agents used in angiography. This three-in-one renoprotective imaging strategy helps prevent kidney injury from being worsened during the CTA examination.

Abstract
Rolling circle amplification (RCA) enables the facile construction of compact and versatile DNA nanoassemblies which are yet rarely explored for intracellular analysis. This is might be ascribed to the uncontrollable and inefficient probe integration/activation. Herein, by encoding with tandem allosteric deoxyribozyme (DNA-cleaving DNAzyme), a multifunctional RCA nanogel was established for realizing the efficient intracellular microRNA imaging via the successive activation of the RCA-disassembly module and signal amplification module. The endogenous microRNA stimulates the precise degradation of DNA nanocarriers, thus leading to the efficient exposure of RCA-entrapped DNAzyme biocatalyst for an amplified readout signal. Our bioorthogonal DNAzyme disassembly strategy achieved the robust analysis of intracellular biomolecules, thus showing more prospects in clinical diagnosis.

Abstract
The rapid, simple and low-cost preparation of DNA micro-nano-architectures remain challenging in biosensing and therapy. Polymerase chain reaction (PCR)-driven DNA micro-nano-flowers are used to construct a nanosized baicalin-compressed-aptamer-nanodrug (bcaND) via one-pot assembly for targeted and synergistic anti-obesity. In the design, the tailored Adipo-8 (tAdi-8) overhang in the PCR amplicon displays anti-obesity targeting activity, while the baicalin loaded in the bcaND by embedding the amplicon plays a three-fold role as a lipid-lowering factor, bcaND size compressor, and uncoupling protein-1 (UCP1)-raised thermogenic activator. The ingenious bcaND represents an advanced multifunctional nanomaterial capable of adjusting the morphology at an optimal 400/1 molar ratio of Mg2+ to phosphate groups, compressing the size from 2.699 µm to 214.76 nm using 1 mg/mL baicalin at a temperature of 70 °C, an effective payload with amplicons of up to 98.94%, and a maximum baicalin load of 86.21 g/g DNA. Responsive release in acidic conditions (pH 5.0) occurs within 72 h, accelerating thermogenesis via UCP1 up-regulation by 2.5-fold in 3T3-L1-preadipocytes and 13.7-fold in the white-adipose-tissue (WAT) of mice, targeting adipocytes and visceral white adipose tissue. It plays an efficient synergistic role in obesity therapy in vitro and in vivo, providing a new direction for DNA self-assembly nanotechnology.

Abstract
Polyphenolic materials are a class of fascinating and versatile bioinspired materials for biointerfacial engineering. In particular, due to the presence of active chemical groups, a series of unique physicochemical properties become accessible and tunable of the as-prepared polyphenolic platforms, which could delicately regulate the cell activities via cell-material contact-dependent interactions. More interestingly, polyphenols could also affect the cell behaviors via cell-material contact-independent manner, which arise due to their intrinsically functional characteristics (e.g., antioxidant and photothermal behaviors). As such, a comprehensive understanding on the relationship between material properties and desired biomedical applications, as well as the underlying mechanism at the cellular and molecular level would provide material design principles and accelerate the lab-to-clinic translation of polyphenolic platforms. In this review, we firstly give a brief overview of cell hallmarks governed by surrounding cues, followed by the introduction of polyphenolic material engineering strategies. Subsequently, a detailed discussion on cell-polyphenols contact-dependent interfacial interaction and contact-independent interaction was also carefully provided. Lastly, their biomedical applications were elaborated. We believe that this review could provide guidances for the rational material design of multifunctional polyphenols and extend their application window.

Abstract
CRISPR/Cas9 is emerging as a platform for gene therapeutics, and the treatment efficiency is expected to be enhanced by combination with other therapeutic agents. Herein, we report a proton-activatable DNA-based nanosystem that enables co-delivery of Cas9/sgRNA and DNAzyme for the combined gene therapy of cancer. Ultra-long ssDNA chains, which contained the recognition sequences of sgRNA in Cas9/sgRNA, DNAzyme sequence and HhaI enzyme cleavage site, were synthesized as the scaffold of the nanosystem. The DNAzyme cofactor Mn2+ was used to compress DNA chains to form nanoparticles and acid-degradable polymer-coated HhaI enzymes were assembled on the surface of nanoparticles. In response to protons in lysosome, the polymer coating was decomposed and HhaI enzyme was consequently exposed to recognize and cut off the cleavage sites, thus triggering the release of Cas9/sgRNA and DNAzyme to regulate gene expressions to achieve a high therapeutic efficacy of breast cancer.

Abstract
The targeted delivery of phytochemicals that promote energy expenditure for obesity therapy remains a challenge. This study assembled a functionalized adipo-8 aptamer loaded with allicin using isothermal rolling-circle techniques to form a synergistic adipocyte-targeted binary-drug delivery system for treating obesity. The functionalized adipo-8 aptamer efficiently protected allicin from adsorption, showing significant potential to encapsulate, transport, and release molecular cargos into white adipose tissue. Introducing the negatively charged allicin, a phytochemical able to induce adipose tissue browning, reduced the diameters of DNA-nanoflower from 770 to 380 nm and increased cellular uptake efficiency up to 118.7%. The intracellular distribution observed via confocal microscopy confirmed the successful receptor recognition mediated by aptamers in the DNA-nanoflower-allicin (NFA) framework as well as its excellent stability to escape from lysosomes. In vivo results demonstrated that subcutaneous administration of NFA effectively promoted adipocyte browning and systematic energy expenditure with minimal side effects. Furthermore, the G-quadruplex in the mitochondrial uncoupling protein-1 promoter was found to be an interactive allicin target for regulating thermogenesis to combat obesity.
