Int J Biol Macromol 2024; 260:129495. [PMID: 38228209 PMCID: PMC11060068 DOI: 10.1016/j.ijbiomac.2024.129495] [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: 07/27/2023] [Revised: 01/10/2024] [Accepted: 01/12/2024] [Indexed: 01/18/2024]
Abstract
DNA's programmable, predictable, and precise self-assembly properties enable structural DNA nanotechnology. DNA nanostructures have a wide range of applications in drug delivery, bioimaging, biosensing, and theranostics. However, physiological conditions, including low cationic ions and the presence of nucleases in biological systems, can limit the efficacy of DNA nanostructures. Several strategies for stabilizing DNA nanostructures have been developed, including i) coating them with biomolecules or polymers, ii) chemical cross-linking of the DNA strands, and iii) modifications of the nucleotides and nucleic acids backbone. These methods significantly enhance the structural stability of DNA nanostructures and thus enable in vivo and in vitro applications. This study reviews the present perspective on the distinctive properties of the DNA molecule and explains various DNA nanostructures, their advantages, and their disadvantages. We provide a brief overview of the biomedical applications of DNA nanostructures and comprehensively discuss possible approaches to improve their biostability. Finally, the shortcomings and challenges of the current biostability approaches are examined.

Abstract
CpG ODNs demonstrate a significant promise for immunotherapy. However, their application is limited owing to quick DNase digestion and inadequate cellular internalization. Transportation of CpG ODNs into immune cells is crucial. Although viral vectors exhibit high transfection efficiency, safety risks, high cost, and low carrying capacity remain big obstacles. Herein, a novel CpG ODNs vector was fabricated by using starch. Starch was ultrasonicated and simply aminated (NH2-St) through grafting with diethylenetriamine, which was spherical with a diameter of 50 nm. NH2-St possessed good biocompatibility. Cationic NH2-St encapsulated CpG ODNs well and possessed a high loading capacity of 317 μg/mg. NH2-St protected CpG ODNs from nuclease digestion and significantly enhanced their cellular uptake. NH2-St/CpG induced the potent secretion of antitumor cytokines from macrophages and effectively suppressed the growth of tumor cells. This work highlights the promise of starch for CpG ODNs delivery, which brings new hope for cancer immunotherapy.

Abstract
The past few decades have witnessed the evolving paradigm for cancer therapy from nonspecific cytotoxic agents to selective, mechanism-based therapeutics, especially immunotherapy. In particular, the integration of nanomaterials with immunotherapy is proven to improve the therapeutic outcome and minimize off-target toxicity in the treatment. As a novel nanomaterial, DNA-based self-assemblies featuring uniform geometries, feasible modifications, programmability, surface addressability, versatility, and intrinsic biocompatibility, are extensively exploited for innovative and effective cancer immunotherapy. In this review, the successful employment of DNA nanoplatforms for cancer immunotherapy, including the delivery of immunogenic cell death inducers, adjuvants and vaccines, immune checkpoint blockers as well as the application in immune cell engineering and adoptive cell therapy is summarized. The remaining challenges and future perspectives regarding the pharmacokinetics/pharmacodynamics, in vivo fate and immunogenicity of DNA materials, and the design of intelligent DNA nanomedicine for individualized cancer immunotherapy are also discussed.

Abstract
Sensitivity and selectivity are critical parameters to evaluate the performance of sensors. For trace detection, it remains a challenge to design a new sensor that achieves high sensitivity and selectivity simultaneously. Here, we present a target-activated dual Mg2+-dependent DNAzyme (MNAzyme) that served as a simple sensing model to explore the multivalency in improving the analytical sensitivity and selectivity for target detection. Mercury ion (Hg2+), a notorious toxic metal ion, was selected as a model target. In the presence of Hg2+, the thymine-rich regions of the hairpin probe and primer could hybridize to form a stable duplex via the thymine-Hg2+-thymine structure. Then, an intact enzyme sequence was exposed and two separate enzyme fragments were close to each other, generating a dual MNAzyme. Benefiting from the localized high-concentration of the enzyme strand, the dual MNAzyme showed a remarkable improvement in binding stability. The catalytic rate constant of the dual MNAzyme was theoretically 1.60 times higher than that of the monomeric counterpart, and the sensitivity and selectivity had 4.50 and 1.44-fold enhancement, respectively. When the dual MNAzyme was used for sensor applications, the limit of detection was determined to be 0.04 and 0.2 nM via UV-vis spectrophotometer and naked eye, respectively. Meanwhile, the method offered desirable selectivity toward Hg2+ against other metal ions. With the advantages of simple operation, high sensitivity, and desirable selectivity, the developed multivalent sensing platform could be easily expanded in the future for the on-site detection of other low-abundance analytes.

Abstract
Cancer immunotherapy is a powerful treatment strategy that mobilizes the immune system to fight disease. Cancer vaccination is one form of cancer immunotherapy, where spatiotemporal control of the delivery of tumor-specific antigens, adjuvants, and/or cytokines has been key to successfully activating the immune system. Nanoscale materials that take advantage of chemistry to control the nanoscale structural arrangement, composition, and release of immunostimulatory components have shown significant promise in this regard. In this Outlook, we examine how the nanoscale structure, chemistry, and composition of immunostimulatory compounds can be modulated to maximize immune response and mitigate off-target effects, focusing on spherical nucleic acids as a model system. Furthermore, we emphasize how chemistry and materials science are driving the rational design and development of next-generation cancer vaccines. Finally, we identify gaps in the field that should be addressed moving forward and outline future directions to galvanize researchers from multiple disciplines to help realize the full potential of this form of cancer immunotherapy through chemistry and rational vaccinology.

Abstract
Guanine-quadruplex (G4) oligodeoxynucleotides (ODNs) that contain unmethylated cytosine-phosphate-guanine motifs (G4 CpG ODN) with phosphodiester backbones are safer than the phosphorothioate (PT)-modified CpG ODNs recently used as vaccine adjuvants. However, cellular uptake and the nuclease stability of G4 CpG ODNs are still insufficient, resulting in lower immunostimulatory activity than PT-modified CpG ODNs. We aimed to enhance the immunostimulatory properties of G4 CpG ODNs by complexing with the cationic liposome 1,2-dioleoyl-3-trimethylammonium-propane (DOTAP). The complex acquired nuclease resistance and improved cellular uptake. The immunostimulatory activity of the G4 CpG ODN-DOTAP lipoplexes was enhanced to a level comparable to that of PT-modified ODNs. In addition, the lipoplexes based on unmodified G4 CpG ODNs demonstrated CpG motif-specific immunostimulant activity, although PT-modified ODNs lacking the CpG motif could activate human immune cells. Interestingly, G4 CpG ODN-DOTAP lipoplexes induced interferon-α production in a loop-length dependent manner.

Abstract
The present study focused on the design and synthesis of covalent DNA dendrons bearing multivalent cytosine-phosphate-guanine oligodeoxynucleotides (CpG ODNs) that can stimulate the immune system through the activation of TLR9. These dendrons were synthesized using branching trebler phosphoramidite containing three identical protecting groups that enabled the simultaneous synthesis of multiple strands on a single molecule. Compared with linear ODNs, covalent DNA dendrons were found to be more resistant to nuclease degradation and were more efficiently taken up by macrophage-like RAW264.7 cells. Cellular uptake was suggested to be mediated by macrophage scavenger receptors. The covalent DNA dendrons composed of multivalent immunostimulatory branches enhanced the secretion of proinflammatory cytokines TNF-α and IL-6 from RAW264.7 cells, and 9-branched DNA dendrons showed the highest enhancement. Given their enhanced efficacy, we expect covalent DNA dendrons to be useful structures of oligonucleotide medicines.

Abstract
In situ stimuli-responsive molecular devices have gained much attention in biomedical areas due to their characteristics of increased image contrast and drug accumulation. Herein, we present a hand-in-hand in situ tile assembly for improved visualization of TK1 mRNA and killing of cancer cells. A pH-responsive and aptamer-functionalized tile motif (pH-Apt-TM) was first formed by four single-strand DNA, possessing pH-responsiveness and intracellular TK1 mRNA recognition capacity. When encountering target cells, the pH-Apt-TM could recognize target receptors on the cell surface through the aptamer domain. Meanwhile, the extracellular acidic pH gathered the pH-Apt-TM into a multifunctional hand-in-hand DNA tile assembly (HDTA) on the cells' surface. Compared to the pH-Apt-TM, studies revealed that the HDTA exhibited enhanced recognition, efficient cellular uptake, and improved visualization of TK1 mRNA, accompanied by gene silencing. Moreover, using Dox as a chemotherapeutic model, specific drug delivery and enhanced cell killing were achieved with target cells.

Abstract
Nanovaccine can elicit antigen-specific immune responses against tumor cells expressing homologous antigens and has attracted enormous attention in cancer immunotherapy. However, tumor heterogeneity remarkably hinders the development of nanovaccines. Here we demonstrate that PTT-induced in situ vaccination cancer therapy can elicit potent antitumor immunity against disseminated and metastatic tumors. Gold nanorods (AuNRs) covalently coupled with amphiphilic polyTLR7/8a and MMP-2-sensitive R9-PEG conjugate (AuNRs-IMQD-R9-PEG) were developed as a new biocompatible PTT agent with favorable photothermal efficiency and stability. Importantly, AuNRs-IMQD-R9-PEG can effectively absorb tumor-derived protein antigens, forming nanovaccines directly in vivo and enhance the activation of host dendritic cells (DCs), thereby amplifying adaptive antitumor T-cell responses, triggering effector memory immune responses, and activating innate antitumor immunity. Remarkably, peri-tumoral administration of low-dose multifunctional AuNRs followed by non-invasive near-infrared (NIR) laser irradiation enables efficient tandem PTT-vaccination treatment modality that can inhibit local as well as untreated distant and metastatic tumors in mice inoculated with poorly immunogenic, highly metastatic 4T1 tumors. Our findings indicate that AuNRs-IMQD-R9-PEG-mediated in situ cancer vaccination provides a powerful immunotherapy characterized by markedly increased infiltration of effector CD8+ T, natural killer T (NKT) cells in tumors and long-term animal survival, thus, offering a promising therapeutic strategy for advanced, disseminated cancers.

Abstract
The immunostimulatory activity of unmethylated cytosine-phosphate-guanine oligodeoxynucleotide (CpG ODN) could be improved via delivery to immune cells expressing Toll-like receptor 9 (TLR9). Previously, we showed that the polypod-like structured nucleic acid (polypodna), a nanostructured DNA comprised of three or more ODNs, was an efficient system for the delivery of CpG ODNs to immune cells. Because some TLR9-positive immune cells express mannose receptors (MR), the uptake of polypodna by immune cells can be further increased by its modification with mannose. In this study, we selected the phosphodiester CpG ODN, ODN1668, which has a sequence identical to CpG1668, and a hexapodna, a polypodna with six pods, to design a hexapodna that harbored ODN1668 or the mannosylated CpG ODN (Man-ODN1668) synthesized via modification of the 5'-terminal of ODN1668 with a synthesized mannose motif. By mixing ODN1668 or Man-ODN1668 with the hexapodna, ODN1668/hexapodna and Man-ODN1668/hexapodna were successfully formed with high yields. However, Man-ODN1668/hexapodna was found to induce a greater tumor necrosis factor-α release from TLR9- and MR-positive mouse peritoneal macrophages and macrophage-like J774.1 cells than Man-ODN1668 or ODN1668/hexapodna. These results indicate that the combination of mannose modification and incorporation into nanostructured DNA is a useful approach for enhancing the immunostimulatory activity of CpG ODN.

Abstract
Unmethylated cytosine-phosphate-guanosine (CpG) oligodeoxynucleotides are immunostimulatory nucleic acids wildly utilized as adjuvants or for vaccines to treat diseases. However, there is a lack of simple and efficient vectors for CpG oligodeoxynucleotide delivery with long-lasting immune stimulation. Herein, self-assembled polymer wires consisting of CpG motifs by hybridization chain reaction were constructed with excellent biocompatibility and immunostimulatory activity. The designed polymer DNA wires acted as programmable multivalent immunoadjuvants and triggered immune response, stimulated pro-inflammatory cytokine secretion, and induced the apoptosis of cancer cells. More strikingly, polymer nanospheres assembled from the polymer DNA wires and cationic poly-l-lysine further improved cellular uptake and continuously stimulate the lysosomal Toll-like receptor 9 of immune cells, thereby remarkably enhancing the activation of immune cells. These results demonstrated that self-assembled polymer DNA nanoassemblies with multivalent CpG could trigger strong immune response and further induce cancer cell death.

Abstract
Immunotherapy has received increasing attention due to its low potential side effects and high specificity. For instance, cancer immunotherapy has achieved great success. CpG is a well-known and commonly used immunotherapeutic and vaccine adjuvant, but it has the disadvantage of being unstable and low in efficacy and needs to be transported through an effective nanocarrier. With perfect structural programmability, permeability, and biocompatibility, DNA nanostructures are one of the most promising candidates to deliver immune components to realize immunotherapy. However, the instability and low capability of the payload of ordinary DNA assemblies limit the relevant applications. Consequently, DNA nanostructure with a firm structure, high drug payloads is highly desirable. In the paper, the latest progress of biostable, high-payload DNA nanoassemblies of various structures, including cage-like DNA nanostructure, DNA particles, DNA polypods, and DNA hydrogel, are reviewed. Cage-like DNA structures hold drug molecules firmly inside the structure and leave a large space within the cavity. These DNA nanostructures use their unique structure to carry abundant CpG, and their biocompatibility and size advantages to enter immune cells to achieve immunotherapy for various diseases. Part of the DNA nanostructures can also achieve more effective treatment in conjunction with other functional components such as aPD1, RNA, TLR ligands.

Abstract
CpG oligodeoxynucleotides (ODNs) have attracted increasing attention as immunotherapeutic agents. However, efficient transfection of CpG ODNs into the immune cells remains a big challenge. In this study, for the first time, we reported that silk fibroin (SF) could function as an efficient carrier for CpG ODNs. A novel strategy was developed to prepare SF-CpG ODNs nanoparticles (NPs) based on self-assembly of SF. The as-prepared SF-CpG NPs were spherical in shape and were uniformly dispersed. SF-CpG NPs exhibited good stability and biocompatibility. SF-CpG NPs possessed significantly enhanced (7 folds) cellular uptake compared with CpG ODNs. Release of CpG ODNs from SF-CpG NPs was accelerated in environment-mimicking TLR9-localized endo/lysosome. SF-CpG NPs stimulated about four folds higher levels of immune cytokines and nitric oxide compared with CpG ODNs. Our results suggested that SF notably improved the CpG ODNs delivery. SF-CpG NPs have strong potential in immunotherapy.

Abstract
The efficient and precise delivery of antisense oligonucleotides (ASOs) to target cells is of great value in gene silencing. However, the specificity and packaging capacity of delivery system still remains challenging. Here, we designed an i-motif forming-initiated in situ bipedal hybridization chain reaction (pH-Apt-BiHCR) amplification strategy for specific target cells imaging and enhanced gene delivery of ASOs. As a proof of concept, an 8-nt ASO modified with locked nucleic acid (LNA) which is complementary to the seed region of microRNA21 (miR-21) was used for gene silencing studies. Benefiting from the design of hairpin-contained i-motif, the stimuli-responsive assembly of pH-Apt-BiHCR was successfully achieved on MCF-7 cells surface based on the specific recognition of aptamer. Using this strategy, the pH-Apt-BiHCR not only contains repeated fluorescence resonance energy transfer (FRET) units for activatable tumor imaging with high contrast but also arrays with plenty of LNA ASOs as interference molecules for cancer cells inhibition. An in vitro assay showed that this strategy presented an excellent response ability in buffer within a narrow pH range (6.0-7.0) with a transition midpoint (pHT) of 6.44 ± 0.06. Moreover, live cell studies revealed that it realized a specific activatable imaging of target cells, while the ASOs arrayed pH-Apt-BiHCR exhibited improved internalization via an endocytosis pathway and enhanced gene silencing to MCF-7 cells compared to single ASO alone. We believe that this design will inspire the development of novel probes for early diagnosis and therapy of cancer cells.

Abstract
To efficiently deliver CpG oligodeoxynucleotides (ODNs) to macrophages for the reversal of cancer-induced immunosuppression, nanoparticles ODN@MCBSA with mannosylated cationic albumin (MCBSA) as a macrophage targeting vector were constructed. Compared with ODN@CBSA with cationic albumin (CBSA) as a vector, ODN@MCBSA exhibited significantly improved cellular uptake mediated by mannose moieties, resulting in significantly enhanced secretion of proflammatory cytokines including IL-12, IL-6, TNF-α, and iNOS. The modulation of macrophages toward the favorable M1 phenotype was confirmed by the upregulated CD80 expression after being treated by ODN delivery systems. In addition to immune cells, the effects of the ODN delivery system on cancerous HeLa cells were also investigated. The results showed that ODN@MCBSA did not affect the overall tumor cell viability. However, enhanced NF-κB, p-Akt, PIK3R3, Fas, and FasL, as well as upregulated caspases were observed in tumor cells, implying the pleiotropic effects on tumor cells. Our study provides a more in-depth understanding on the immunotherapeutic effects of CpG ODNs and highlights the importance of macrophage targeting delivery to minimize the effects on tumor cells. These results indicate that MCBSA could serve as a promising delivery vector of CpG ODNs to macrophages for cancer immunotherapy.

Abstract
Inactivated vaccines are widely used for prevention of viral disease. Both humoral and cellular immune responses have been shown to play important roles in the control and clearance of virus infections. CpG motif containing oligodeoxynucleotides (ODN) have recently gained considerable interest and been used as vaccine adjuvant due to their potent abilities to modulate host immune response. In this study, CpG-ODN adjuvant and inactivated viral particles of enterovirus 71 (EV71) were co-encapsulated into nanoparticles (NP) generated by using protamine sulfate (PS) and carboxymethyl β-glucan (CMG) through a self-assembly approach. The administration of EV71 nanovaccine elicited not only specific anti-EV71 neutralizing antibody response, but also cellular immune response characterized by strong productions of IFN-α and IFN-γ. The results suggest that CMG/PS-based nanovehicles hold a great potential to be a novel platform for nanovaccine development against viral disease.

Abstract
Here, we have developed a localized catalytic hairpin assembly (LCHA) strategy for intracellular miR-21 imaging by using DNA nanowires confining both hairpin probes in a compact space. The LCHA is constructed by interval hybridization of DNA hairpin probe pairs to a DNA nanowire with multiplex footholds generated by alternating chain hybridization. Compared to the conventional catalytic hairpin assembly (CHA) strategy, the LCHA significantly shortens the reaction time and enhances the sensitivity. Moreover, the proposed LCHA can serve as a carrier for delivery of probes into live cells as well as protect the probes from nuclease degradation and enhances the stability. We anticipate that this design can be widely applied in facilitating basic biomedical research and disease diagnosis.

Abstract
It is challenging but imperative to merge imaging agents and small molecule therapeutics into one nanoentity for diagnosis and treatment. Herein, we constructed polymeric nanoparticles for targeted delivery and combination chemotherapy, which formed through host-guest interactions among three elements: 1) β-cyclodextrin polymer (poly-β-CD), as the backbone of nanoparticles; 2) two antitumor drugs-doxorubicin (DOX) and docetaxel (DTX); and 3) aptamers labeled with adamantane and fluorescein (Ad-aptamer-FAM), as recognition elements. First, polymeric nanoparticles, termed self-assembled supramolecular nanoparticles (SSNPs), were formulated by combining hydrophobic DTX and DOX with poly-β-CD via host-guest interactions. Then, the surface of SSNPs modified the aptamer to acquire targeting ability; such nanoparticles were termed targeted self-assembled supramolecular nanoparticles (T-SSNPs). As evidenced by MTS assay data, T-SSNPs exhibited significant selective cytotoxicity toward target cells. The results also indicated that combination drugs achieved a good synergistic effect with a combination index of 0.43. Thus, an effective and simple drug delivery system was constructed for targeted delivery and combination chemotherapy.

Abstract
CpG oligodeoxynucleotides (CpG ODNs) possess strong immunostimulatory activity, which hold great promise in cancer immunotherapy. However, their therapeutic efficacy is largely limited due to nuclease degradation and poor cellular internalization. Efficiently delivering CpG ODNs into target cells is crucial to improve their therapeutic efficacy. Boron nitride nanospheres (BNNS) possess advantage as carriers for CpG ODNs. However, their poor aqueous dispersity and low CpG ODN loading capacity became a big obstacle for further applications. Herein, we develop amino group grafted, mesoporous silica (MS)-functionalized BNNS as novel nanovectors for CpG ODN delivery. Modification of BNNS with MS significantly improved the dispersity of BNNS and CpG ODN loading. BNNS@MS-NH2 exhibited no cytotoxicity and enhanced the delivery of CpG ODNs into macrophages. BNNS@MS-NH2/CpG ODN complexes triggered enhanced immunostimulation and induced higher amounts of cytokines. Most importantly, BNNS@MS-NH2/CpG ODN complexes induced bifurcated cytokines, which simultaneously simulated the secretion of IL-6, TNF-α and IFN-α. In contrast, CpG ODN and BNNS/CpG ODN complexes could not. The result of the Transwell plate assay suggested that BNNS@MS-NH2/CpG ODN complexes were more effective in inhibiting cancer cell growth. Taken together, our findings provide a promising strategy for enhancing CpG ODN-mediated cancer immunotherapy.

Abstract
To overcome cancer-associated immunosuppression, we prepared a dual-targeting vector to deliver CpG oligodeoxynucleotides (ODN) to macrophages. The dual-targeting system composed of mannosylated carboxymethyl chitosan (MCMC)/hyaluronan (HA) for macrophage targeting and protamine sulfate for ODN complexation was prepared by self-assembly. The effects of ODN delivery on immune cells was studied in J774A.1 cells. Due to the enhanced delivery efficiency, the dual-targeting delivery system exhibits a higher immune stimulatory activity compared with the monotargeting delivery system containing either MCMC or HA, resulting in a dramatically enhanced secretion of proinflammatory cytokines and a successful shift to activated macrophages (M1). Besides macrophages, the influence of the delivery system on tumor cells (MCF-7) was also investigated. In MCF-7 cells, the increased expressions of nuclear transcription factor-κB (NF-κB), PIK3R3, and phosphorylated protein kinase B (p-Akt) caused by activated NF-κB and phosphoinositide 3-kinase/Akt signalings were observed. Nevertheless, upregulated Fas as well as Fas ligand (FasL) may induce Fas/FasL-mediated apoptosis, which results in the increased expressions of caspases in tumor cells.
