Abstract
Unmethylated cytosine-phosphate-guanine (CpG) oligodeoxynucleotides (ODNs), which were therapeutic DNA with high immunostimulatory activity, have been applied in widespread applications from basic research to clinics as therapeutic agents for cancer immunotherapy, viral infection, allergic diseases and asthma since their discovery in 1995. The major factors to consider for clinical translation using CpG motifs are the protection of CpG ODNs from DNase degradation and the delivery of CpG ODNs to the Toll-like receptor-9 expressed human B-cells and plasmacytoid dendritic cells. Therefore, great efforts have been devoted to the advances of efficient delivery systems for CpG ODNs. In this review, we outline new horizons and recent developments in this field, providing a comprehensive summary of the nanoparticle-based CpG delivery systems developed to improve the efficacy of CpG-mediated immune responses, including DNA nanostructures, inorganic nanoparticles, polymer nanoparticles, metal-organic-frameworks, lipid-based nanosystems, proteins and peptides, as well as exosomes and cell membrane nanoparticles. Moreover, future challenges in the establishment of CpG delivery systems for immunotherapeutic applications are discussed. We expect that the continuously growing interest in the development of CpG-based immunotherapy will certainly fuel the excitement and stimulation in medicine research.

Abstract
Acute liver failure (ALF) is a critical life-threatening disease that occurs due to a rapid loss in hepatocyte functions. Hepatocyte transplantation holds great potential for ALF treatment, as it rapidly supports liver biofunctions and enhances liver regeneration. However, hepatocyte transplantation is still limited by renewable and ongoing cell sources. In addition, intravenously injected hepatocytes are primarily trapped in the lungs and have limited efficacy because of the rapid clearance in vivo. Here, we designed a Y-shaped DNA nanostructure to deliver microRNA-122 (Y-miR122), which could induce the hepatic differentiation and maturation of human mesenchymal stem cells. mRNA sequencing analysis revealed that the Y-miR122 promoted important hepatic biofunctions of the induced hepatocyte-like cells including fat and lipid metabolism, drug metabolism, and liver development. To further improve hepatocyte transplantation efficiency and therapeutic effects in ALF treatment, we fabricated protective microgels for the delivery of Y-miR122-induced hepatocyte-like cells based on droplet microfluidic technology. When cocultured with human umbilical vein endothelial cells in microgels, the hepatocyte-like cells exhibited an increase in hepatocyte-associated functions, including albumin secretion and cytochrome P450 activity. Notably, upon transplantation into the ALF mouse model, the multiple cell-laden microgels effectively induced the restoration of liver function and enhanced liver regeneration. Overall, this study presents an efficient approach from the generation of hepatocyte-like cells to hepatocyte transplantation in ALF therapy.

Abstract
Immunomodulation is a powerful therapeutic approach that harnesses the body's own immune system and reprograms it to treat diseases, such as cancer. Innate immunity is key in mobilizing the rest of the immune system to respond to disease and is thus an attractive target for immunomodulation. Biomaterials have widely been employed as vehicles to deliver immunomodulatory therapeutic cargo to immune cells and raise robust antitumor immunity. However, it is key to consider the design of biomaterial chemical and physical structure, as it has direct impacts on innate immune activation and antigen presentation to stimulate downstream adaptive immunity. Herein, we highlight the widespread importance of structure-driven biomaterial design for the delivery of immunomodulatory cargo to innate immune cells. The incorporation of precise structural elements can be harnessed to improve delivery kinetics, uptake, and the targeting of biomaterials into innate immune cells, and enhance immune activation against cancer through temporal and spatial processing of cargo to overcome the immunosuppressive tumor microenvironment. Structural design of immunomodulatory biomaterials will profoundly improve the efficacy of current cancer immunotherapies by maximizing the impact of the innate immune system and thus has far-reaching translational potential against other diseases.

Intradermal delivery of Cryj1 loaded in CpG DNA hydrogel for inhibiting allergic reactions in mice. J Control Release 2023; 354:429-438.

Abstract
Immunotherapy for allergic rhinitis alleviates symptoms associated with antigen exposure by administering pathogenic antigens. However, many current immunotherapies fail to induce sufficient immune responses, resulting in frequent and prolonged hospital visits. Consequently, the development of more effective immunotherapies is necessary. In this study, we focused on the skin, which is rich in immune cells, as an administration site for inducing antigen-specific immune responses. To efficiently and sustainably deliver the cedar pollen antigen Cryj1 to immune cells, we attempted to load Cryj1 in an immunostimulatory CpG DNA hydrogel, prepared using self-gelatinizable nucleic acid technology. In this technology, the hydrogel became gelatinized by self-assembly of multiple predesigned DNA units containing potent CpG motifs. Cryj1 loaded in the CpG DNA hydrogel showed sustained release, was taken up by mouse macrophage-like RAW264.7 and mouse dendritic DC2.4 cells, and induced efficient production of interleukin-12 after intradermal injection into mice. Intradermal injection of Cryj1 loaded CpG DNA hydrogel into mice increased the production of Cryj1-specific IgG while suppressing the production of immunoglobulin E (IgE) antibodies. Furthermore, when Cryj1 was resensitized to mice, a stronger induction of IgG production and suppression of IgE production was observed. These results suggest that intradermal administration of Cryj1 loaded CpG DNA hydrogel is a novel immunotherapy for allergic symptoms caused by cedar pollen and can be used as a replacement for current immunotherapies.

Abstract
Some chemotherapeutic agents, such as anthracyclines and oxaliplatin, can induce immunogenic cell death (ICD) with additional immune responses against cancer. However, ICD-based immunotherapy is limited by the nonspecific distribution of drugs and various side effects. Here, an immunostimulatory self-assembled tetrahedral framework nucleic acid (tFNA) vehicle was constructed to potentiate the chemo-immunotherapy, in which doxorubicin (DOX) acted as a chemotherapeutic agent and an ICD-inducer. Meanwhile, the immunostimulatory CpG-tFNA was employed as a nanocarrier to deliver DOX and an adjuvant to enhance the immunotherapy. Damage-associated molecular patterns (DAMPs) generated by DOX from dying tumor cells, such as calreticulin (CRT), high mobility group protein 1(HMGB1), and adenosine triphosphate (ATP), can activate dendritic cells (DCs) and trigger an immunological response. Afterward, CpG-tFNA with immunostimulatory properties works to boost the DOX-induced immunotherapy. Consequently, CpG-tFNA/DOX showed excellent antitumor effects and immunological activation, including CD8+ T cell proliferation and antitumor cytokine TNF-α and IFN-γ secretion. Moreover, chemo-immunotherapy can also be enhanced synergistically when coadministered with PD-L1. In conclusion, CpG-tFNA/DOX promotes the ICD-associated chemo-immunotherapy and strengthens the connection between traditional chemotherapy and immunotherapy, representing a novel strategy for clinical application. Moreover, the concept of ICD-related immunotherapy can also be extended to other treatments such as radiotherapy which can induce immunogenic cell death as well.

Abstract
Deoxyribonucleic acid (DNA) nanotechnology, a frontier in biomedical engineering, is an emerging field that has enabled the engineering of molecular-scale DNA materials with applications in biomedicine such as bioimaging, biodetection, and drug delivery over the past decades. The programmability of DNA nanostructures allows the precise engineering of DNA nanocarriers with controllable shapes, sizes, surface chemistries, and functions to deliver therapeutic and functional payloads to target cells with higher efficiency and enhanced specificity. Programmability and control over design also allow the creation of dynamic devices, such as DNA nanorobots, that can react to external stimuli and execute programmed tasks. This review focuses on the current findings and progress in the field, mainly on the employment of DNA nanostructures such as DNA origami nanorobots, DNA nanotubes, DNA tetrahedra, DNA boxes, and DNA nanoflowers in the biomedical field for therapeutic purposes. We will also discuss the fate of DNA nanostructures in living cells, the major obstacles to overcome, that is, the stability of DNA nanostructures in biomedical applications, and the opportunities for DNA nanostructure-based drug delivery in the future.

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
DNA, a genetic material, has been employed in different scientific directions for various biological applications as driven by DNA nanotechnology in the past decades, including tissue regeneration, disease prevention, inflammation inhibition, bioimaging, biosensing, diagnosis, antitumor drug delivery, and therapeutics. With the rapid progress in DNA nanotechnology, multitudinous DNA nanomaterials have been designed with different shape and size based on the classic Watson-Crick base-pairing for molecular self-assembly. Some DNA materials could functionally change cell biological behaviors, such as cell migration, cell proliferation, cell differentiation, autophagy, and anti-inflammatory effects. Some single-stranded DNAs (ssDNAs) or RNAs with secondary structures via self-pairing, named aptamer, possess the ability of targeting, which are selected by systematic evolution of ligands by exponential enrichment (SELEX) and applied for tumor targeted diagnosis and treatment. Some DNA nanomaterials with three-dimensional (3D) nanostructures and stable structures are investigated as drug carrier systems to delivery multiple antitumor medicine or gene therapeutic agents. While the functional DNA nanostructures have promoted the development of the DNA nanotechnology with innovative designs and preparation strategies, and also proved with great potential in the biological and medical use, there is still a long way to go for the eventual application of DNA materials in real life. Here in this review, we conducted a comprehensive survey of the structural development history of various DNA nanomaterials, introduced the principles of different DNA nanomaterials, summarized their biological applications in different fields, and discussed the current challenges and further directions that could help to achieve their applications in the future.

Abstract
Inflammation is a crucial part of wound healing and pathogen clearance. However, it can also play a role in exacerbating chronic diseases and cancer progression when not regulated properly. A subset of current innate immune engineering research is focused on how molecules such as lipids, proteins, and nucleic acids native to a healthy inflammatory response can be harnessed in the context of biomaterial design to promote healing, decrease disease severity, and prolong survival. The engineered biomaterials in this review inhibit inflammation by releasing anti-inflammatory cytokines, sequestering proinflammatory cytokines, and promoting phenotype switching of macrophages in chronic inflammatory disease models. Conversely, other biomaterials discussed here promote inflammation by mimicking pathogen invasion to inhibit tumor growth in cancer models. The form that these biomaterials take spans a spectrum from nanoparticles to large-scale hydrogels to surface coatings on medical devices. Cell-inspired molecules have been incorporated in a variety of creative ways, including loaded into or onto the surface of biomaterials or used as the biomaterials themselves.

Abstract
INTRODUCTION Considerable efforts have been made to treat and prevent acute and chronic infections caused by the hepatitis C virus (HCV). Current treatments are unable to protect people from reinfection. Hence, there is a need for development of both preventive and therapeutic HCV vaccines. Many vaccine candidates are in development to fight against HCV, but their efficacy has so far proven limited partly due to low immunogenicity. AREAS COVERED We explore development of novel and powerful adjuvants to achieve an effective HCV vaccine. The basis for developing strong adjuvants is to understand the innate immunity pathway, which subsequently stimulates humoral and cellular immune responses. We have also investigated immunogenicity of developed adjuvants that have been used in recent studies available in online databases such as PubMed, PMC, ScienceDirect, Google Scholar, etc. EXPERT OPINION Adjuvants are used as a part of vaccine formulation to boost vaccine immunogenicity and antigen delivery. Several FDA-approved adjuvants are used in licensed human vaccines. Unfortunately, no adjuvant has yet been proven to boost HCV immune responses to the extent needed for an effective vaccine. One of the promising approaches for developing an effective adjuvant is the combination of various adjuvants to trigger several innate immune responses, leading to activation of adaptive immunity.[Figure: see text].

Abstract
The immune system plays a key role in restraining tumor progression. Therefore, enhancing immune functions using immune stimulants, such as unmethylated CpG oligonucleotides, has emerged as a promising strategy for antitumor therapy. However, poor cellular uptake of negatively charged oligonucleotides and M2 polarization of tumor-associated macrophages remain two major challenges for CpG-based immunotherapy. Herein, we construct a spherical nucleic acid (SNA)-like nanogel assembled by a CpG-grafted polycaprolactone (CpG-g-PCL) brush and an anti-STAT3 siRNA crosslinker for synergistic tumor immunotherapy. After accumulation at the tumor site, this dual siRNA- and CpG-bearing nanogel (CpGgel-siSTAT3) can efficiently trigger M1 type macrophage activation and deter its M2 polarization via block STAT3 signaling, increase the intratumor CD8+ T cell infiltration, and thus successfully restrain tumor growth. Our study demonstrates the new potential of a nucleic acid nanogel platform for the co-delivery of different therapeutic oligonucleotides and combinatorial CpG-based immunotherapy.

Abstract
Subunit vaccines based on antigen-encoding nucleic acids have shown great promise for antigen-specific immunization against cancer and infectious diseases. Vaccines require immunostimulatory adjuvants to activate the innate immune system and trigger specific adaptive immune responses. However, the incorporation of immunoadjuvants into nonviral nucleic acid delivery systems often results in fairly complex structures that are difficult to mass-produce and characterize. In recent years, minimalist approaches have emerged to reduce the number of components used in vaccines. In these approaches, delivery materials, such as lipids and polymers, and/or pDNA/mRNA are designed to simultaneously possess several functionalities of immunostimulatory adjuvants. Such multifunctional immunoadjuvants encode antigens, encapsulate nucleic acids, and control their pharmacokinetic or cellular fate. Herein, we review a diverse class of multifunctional immunoadjuvants in nucleic acid subunit vaccines and provide a detailed description of their mechanisms of adjuvanticity and induction of specific immune responses.

Abstract
Nucleic acid probes have the advantages of excellent biocompatibility, biodegradability, versatile functionalities and remarkable programmability. However, the low biostability of nucleic acid probes under complex physiological conditions limits their in vivo application. Despite impressive progress in the development of inorganic material-mediated biostable nucleic acid nanostructures, uncertain systemic toxicity of composite nanocarriers has hindered their application in living organisms. In the field of biomedicine, as a promising alternative capable of avoiding potential cytotoxicity, biologically stable nanostructures composed entirely of DNA oligonucleotides have been rapidly developed in recent years, offering an exciting in vivo tool for cancer diagnosis and clinical treatment. In this review, we summarize the recent advances in the development of nuclease-resistant DNA nanostructures with different geometrical shapes, such as tetrahedron, octahedron, DNA triangular prism (DTP), DNA nanotubes and DNA origami, introduce innovative assembly strategies, and discuss unique structural advantages and especially biological applications in cellular imaging and targeted drug delivery in an organism. Finally, we conclude with the challenges in the clinical development of DNA nanostructures and present an outlook of the future of this rapidly expanding field.

Abstract
Throughout history, humanity has been threatened by countless epidemic and pandemic outbreaks of infectious diseases, from the Justinianic Plague to the Spanish flu to COVID-19. While numerous antimicrobial and antiviral drugs have been developed over the last 200 years to face these threats, the globalized and highly connected world of the 21st century demands for an ever-increasing efficiency in the detection and treatment of infectious diseases. Consequently, the rapidly evolving field of nanomedicine has taken up the challenge and developed a plethora of strategies to fight infectious diseases with the help of various nanomaterials such as noble metal nanoparticles, liposomes, nanogels, and virus capsids. DNA nanotechnology represents a comparatively recent addition to the nanomedicine arsenal, which, over the past decade, has made great progress in the area of cancer diagnostics and therapy. However, the past few years have seen also an increasing number of DNA nanotechnology-related studies that particularly focus on the detection and inhibition of microbial and viral pathogens. Herein, a brief overview of this rather young research field is provided, successful concepts as well as potential challenges are identified, and promising directions for future research are highlighted.

Abstract
DNA nanotechnology holds substantial promise for future biomedical engineering and the development of novel therapies and diagnostic assays. The subnanometer-level addressability of DNA nanostructures allows for their precise and tailored modification with numerous chemical and biological entities, which makes them fit to serve as accurate diagnostic tools and multifunctional carriers for targeted drug delivery. The absolute control over shape, size, and function enables the fabrication of tailored and dynamic devices, such as DNA nanorobots that can execute programmed tasks and react to various external stimuli. Even though several studies have demonstrated the successful operation of various biomedical DNA nanostructures both in vitro and in vivo, major obstacles remain on the path to real-world applications of DNA-based nanomedicine. Here, we summarize the current status of the field and the main implementations of biomedical DNA nanostructures. In particular, we focus on open challenges and untackled issues and discuss possible solutions.

Abstract
Synthetic oligodeoxynucleotides (ODNs) containing unmethylated cytosine-phosphate-guanine (CpG) motifs trigger the immune response by stimulating endosomal Toll-like receptor (TLR) 9. Natural linear ODNs are susceptible to nuclease degradation, thereby limiting their clinical applications. Here, we designed monomeric G-quadruplex-based CpG ODNs (G4 CpG ODNs) containing CpG motifs in the central loop region of the G4 structure. The monomeric G4 CpG ODNs were more stable in serum than the linear ODNs. The monomeric G4 CpG ODNs containing two or three CpG motifs induced the production of immunostimulatory cytokines interleukin (IL)-6, IL-12, and interferon (IFN)-β in mouse macrophage-like RAW264 cells. We also showed that the number of CpG motifs and the number of nucleotides between the CpG motif and G-tracts define the efficacy of the G4 CpG ODNs in activating TLR9. Incubating human peripheral blood mononuclear cells with G4 CpG ODNs promoted IL-6 and IFN-γ production, confirming their stimulatory effects on human immune cells. Mice given intraperitoneal injections of G4 CpG ODNs produced higher plasma IL-6 compared with injections of linear ODNs. These findings provide further understanding of the parameters governing the immunostimulatory activity of G4 CpG ODNs, thereby providing insights into the rational design of highly potent G4 CpG ODNs for vaccine adjuvants.

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
Most vaccines developed today include only the antigens that best stimulate the immune system rather than the entire virus or microbe, which makes vaccine production and use safer and easier, though they lack potency to induce acceptable immunity and long-term protection. The incorporation of additional immune stimulating components, named adjuvants, is required to generate a strong protective immune response. Nucleic acids (DNA and RNA) and their synthetic analogs are promising candidates as vaccine adjuvants activating Toll-like receptors (TLRs). Additionally, in the last few years several nanocarriers have emerged as platforms for targeted co-delivery of antigens and adjuvants. In this review, we focus on the recent developments in polymer nanomaterials presenting nucleic acids as vaccine adjuvants. We aim to compare the effectiveness of the various classes of polymers in immune modulating materials (nanoparticles, dendrimers, single-chain particles, nanogels, polymersomes and DNA-based architectures). In particular, we address the critical role of parameters such as size, shape, complexation and release of TLR ligands, cellular uptake, stability, toxicity and potential importance of spatial control in ligand presentation.

Abstract
DNA and RNA, the nucleic acids found in every living organism, are quite crucial, because not only do they store the genetic information, but also they are used as signals through interaction with various molecules within the body. The nature of nucleic acids, especially DNA, to form double-helix makes it possible to design nucleic acid-based nanostructures with various shapes. Because the shapes as well as the physicochemical properties determine their interaction with proteins or cells, nanostructured DNAs will have different features in the interaction compared with single- or double-stranded DNA. Some of these unique features of nanostructured DNA make ways for efficient delivery of therapeutic agents to specific targets. In this review, we begin with the factors affecting the properties of nanostructured DNA, followed by summarizing the methods for the development of nanostructured DNA. Further, we discuss the characteristics of nanostructured DNA and their applications for the delivery of bioactive compounds.

Abstract
Single-strand oligodeoxynucleotides (ODNs) containing unmethylated cytosine-phosphate-guanine (CpG) are recognized by the toll-like receptor 9, a component of the innate immunity. Therefore, they could act as immunotherapeutic agents. Chemically modified CpG ODNs containing a phosphorothioate backbone instead of phosphodiester (PD) were developed as immunotherapeutic agents resistant to nuclease degradation. However, they cause adverse side effects, and so there is a necessity to generate novel CpG ODNs. In the present study, we designed a nuclease-resistant nonmodified CpG ODN that forms G-quadruplex structures. G-quadruplex formation in CpG ODNs increased nuclease resistance and cellular uptake. The CpG ODNs designed in this study induced interleukin-6 production in a human B lymphocyte cell line and human peripheral blood mononuclear cells. These results indicate that G-quadruplex formation can be used to increase the immunostimulatory activity of CpG ODNs having a natural PD backbone.

Abstract
Immunostimulatory oligodeoxynucleotides (DNAs) have been widely studied in pharmaceutical and biomedical research fields for applications in cancer immunotherapy and vaccination. Toll-like receptors (TLRs) are critical for the instruction and orchestration of the host immune system composed of innate and adaptive immunity. In particular, TLR9 responds to DNAs with unmethylated deoxycytosine-deoxyguanosine (CpG) motifs, thereby inducing the activation of innate immune cells, such as dendritic cells, and consequently, adaptive immune cells. In this study, we developed two kinds of Y-shaped double-stranded DNA nanostructures (Y-DNAs), including a single unit composed of three DNA strands (YS-DNA) and a ligated multiunit complex formed by crosslinking each YS-DNA (YL-DNA), and investigated whether they have immunostimulatory activity in innate immune cells. YS-DNA and YL-DNA induced the production of immune cytokines such as IL-12 and TNF-α and the expression of costimulatory molecules such as CD80 and CD86 in primary mouse dendritic cells and macrophage cells (RAW264.7 cells). A Coprecipitation study demonstrated that YL-DNA was directly associated with TLR9. The induction of immune cytokines by YS-DNA and YL-DNA was abolished in TLR9-deficient primary mouse dendritic cells. The results demonstrated that Y-DNAs induced the activation of dendritic cells and macrophages mediated by the activation of TLR9, as shown by the expression of immune cytokines and costimulatory molecules. The results suggest that Y-DNA nanostructures provide a beneficial strategy for immunotherapy by modulating the immune system.

Development of orally-deliverable DNA hydrogel by microemulsification and chitosan coating. Int J Pharm 2018; 547:556-562.

Abstract
Self-gelling DNA hydrogels with cytosine-phosphate-guanine (CpG) motifs have been shown to exhibit high potency as vaccine adjuvants. However, their oral use is limited because of their thermodynamic and chemical instability in the gastrointestinal tract. In this study, we aimed to develop DNA hydrogel microspheres (Dgel-MS) coated with chitosan to improve their stability. Chitosan-coated Dgel-MS (Cs-Dgel-MS) was prepared by emulsifying Dgel to obtain the D-gel core, followed by mixing with microemulsions of chitosan for electrostatic coating. Fluorescence imaging of Cs-Dgel-MS labeled with fluorescent dyes showed that Dgel-MS (approximately 30 μm) was coated with chitosan. The recovery efficiency of Alexa Fluor 488-DNA was 87.4 ± 7.5%. To load a phosphorothioate CpG oligodeoxynucleotide into Dgel, a modified Dgel (mDgel) was designed and fluorescein isothiocyanate (FITC)-dextran was loaded into Cs-mDgel-MS as a model compound. The recovery efficiency of Alexa Fluor 488-CpG1668 and FITC-dextran was 83.3 ± 3.8% and 67.8 ± 4.6%, respectively. The release of Alexa Fluor 488-CpG1668 from Cs-mDgel-MS was slower than that from mDgel under acidic or DNase conditions. Intra-duodenal administration of FITC-dextran/Cs-mDgel-MS showed prolonged intestinal transition of the encapsulated FITC-dextran. These results indicate that Cs-Dgel-MS can be useful for oral delivery of CpG DNA and other bioactive compounds.

Abstract
Phosphorodiamidate morpholino oligonucleotides (PMOs) are a class of antisense oligonucleotides used in the treatment of neuromuscular diseases. Their major drawbacks are high blood clearance and poor cellular delivery. Previously, we demonstrated that tripod-like nanostructured DNA, or tripodna, was efficiently taken up by macrophages and dendritic cells. In this study, we used iodine-125(125I)-labelled PMOs, designed a tripodna harbouring an 125I-PMO (125I-PMO/tripodna), and evaluated whether this tripodna could control the pharmacokinetic properties of PMO. Gel electrophoresis showed that 125I-PMO was almost completely incorporated into the tripodna. Compared to 125I-PMO, 125I-PMO/tripodna was more efficiently taken up by macrophage-like RAW264.7 cells. Moreover, after intravenous injection into mice, the area under the plasma concentration-time curve of 125I-PMO/tripodna was significantly larger than that of 125I-PMO. The distribution of 125I-PMO/tripodna in the liver and spleen at 24 h was 32- and 51-fold higher than that of 125I-PMO, respectively. The fractionation of liver cells revealed that non-parenchymal cells were the major cells contributing to the hepatic uptake of 125I-PMO/tripodna. These results indicate that tripodna has the potential to deliver PMO, particularly to the liver and spleen.

Abstract
DNA is emerging as a smart material to construct nanovehicles for targeted drug delivery. The programmability of Watson-Crick base paring enables construction of defined and dynamic DNA nanostructures of almost arbitrary shape and DNA can readily be functionalized with a variety of molecular modules. The applications of DNA nanostructures are still in its infancy, but one of the high expectations are to deliver solutions for targeted therapy. Nucleic acids, however, do not easily enter cells unassisted and biological barriers and harsh nucleolytic conditions in the human body must also be overcome. Here, we highlight recent strategies for DNA nanostructures in drug delivery, DNA nanovehicles, to facilitate targeting and crossing of the biological barriers. In light of this, we discuss future solutions and challenges for DNA nanovehicles to unravel their great potential to facilitate targeted drug delivery.

Abstract
DNA origami is a DNA-based nanotechnology that utilizes programmed combinations of short complementary oligonucleotides to fold a large single strand of DNA into precise 2D and 3D shapes. The exquisite nanoscale shape control of this inherently biocompatible material is combined with the potential to spatially address the origami structures with diverse cargoes including drugs, antibodies, nucleic acid sequences, small molecules, and inorganic particles. This programmable flexibility enables the fabrication of precise nanoscale devices that have already shown great potential for biomedical applications such as: drug delivery, biosensing, and synthetic nanopore formation. Here, the advances in the DNA-origami field since its inception several years ago are reviewed with a focus on how these DNA-nanodevices can be designed to interact with cells to direct or probe their behavior.

Abstract
We explored in detail the relationship between the structure in aqueous solution and immunostimulatory activity of polypod-shaped DNAs, called polypodnas. The polypodnas were constructed using 3-6 oligodeoxynucleotides (ODNs) to obtain tri-, tetra-, penta-, and hexapodna, each of which had 3, 4, 5, and 6 arms made of double-stranded DNA, respectively. A highly potent immunostimulatory CpG sequence was included into each of the polypodnas. Synchrotron X-ray scattering analysis showed that the double-stranded DNA arms of all of the polypodnas adopted a B-form DNA conformation. The analysis also suggested that some nucleotides in the central parts of pentapodna and hexapodna did not form base pairs, whereas those of tripodna and tetrapodna all formed base pairs. This difference would occur because of an increase in steric hindrance and electrical repulsion with increasing number of arms. The pentapodna and hexapodna induced a large amount of tumor necrosis factor α-release from macrophage-like cells compared with the tripodna and tetrapodna, suggesting that the partly loosened DNA in polypodna with many arms is advantageous for exposing the immunostimulatory sequences of the polypodna.

Abstract
Synthetic oligodeoxynucleotides containing immunostimulatory CpG motif mimic bacterial DNA and are potent activator of innate and adaptive immune responses. Therefore, CpG ODNs have significant potentials as immunotherapeutic agent for treatment of infectious diseases, allergy and cancer. Many clinical trials involving CpG ODNs either used alone or as adjuvant have been initiated. However, delivery of CpG ODNs to target sites still remains a great challenge due to their extreme susceptibility to nuclease degradation in serum and poor cellular uptake. Chemical modification of CpG ODNs backbone can protect them against degradation by nucleases, but have raised concern regarding several severe side effects. Development of efficient CpG ODNs delivery systems to address these issues and enhance their immunostimulatory effect are highly desirable. In recent years, the emergence of nanotechnology has provided unprecedented opportunities to encapsulate CpG ODN into various nanocarriers or synthesize CpG ODNs nanostructures. This review provides an overview of the delivery systems based on nanomaterials and nanostructures newly developed for enhancing the immunostimulatory effect of CpG ODNs, together with a brief discussion on perspectives for future studies in this field.

Abstract
The application of DNA as a functional material such as DNA hydrogel has attracted much attention. Despite an increasing interest, the high cost of DNA synthesis is a limiting factor for its utilization. To reduce the cost, we report here a highly efficient amplification technique for polypod-like structured DNA (polypodna) with adhesive ends that spontaneously forms DNA hydrogel. Two types of polypodna with three (tripodna) and four (tetrapodna) pods were selected, and a template oligodeoxynucleotide, containing a tandem sequence of a looped tripodna or tetrapodna, respectively, along with restriction enzyme (TspRI) sites, was designed. The template was circularized using T4 DNA ligase, and amplified by rolling circle amplification (RCA). The RCA product was highly viscous and resistant to restriction digestion. Observation under an electron microscope revealed microflower-like structures. These structures were composed of long DNA and magnesium pyrophosphate, and their treatment with EDTA followed by restriction digestion with TspRI resulted in numerous copies of polypodna with adhesive ends, which formed a DNA hydrogel. Thus, we believe this technique provides a new approach to produce DNA nanostructures, and helps in expanding their practical applications.

Abstract
The programmability of Watson-Crick base pairing, combined with a decrease in the cost of synthesis, has made DNA a widely used material for the assembly of molecular structures and dynamic molecular devices. Working in cell-free settings, researchers in DNA nanotechnology have been able to scale up system complexity and quantitatively characterize reaction mechanisms to an extent that is infeasible for engineered gene circuits or other cell-based technologies. However, the most intriguing applications of DNA nanotechnology - applications that best take advantage of the small size, biocompatibility and programmability of DNA-based systems - lie at the interface with biology. Here, we review recent progress in the transition of DNA nanotechnology from the test tube to the cell. We highlight key successes in the development of DNA-based imaging probes, prototypes of smart therapeutics and drug delivery systems, and explore the future challenges and opportunities for cellular DNA nanotechnology.

Abstract
In this study, we proposed to modify mesoporous silica nanoparticles (MSNs) with 3-aminopropyltriethoxysilane (NH2-TES), aminoethylaminopropyltriethoxysilane (2NH2-TES) and 3-[2-(2-aminoethylamino)ethylamino] propyl-trimethoxysilane (3NH2-TES) for binding of cytosine-phosphate-guanosine oligodexynucleotides (CpG ODN), and investigated the effect of different amino groups of MSNs on the CpG ODN delivery. Serum stability, in vitro cytotoxicity, and cytokine interleukin-6 (IL-6) induction by MSN-NH2/CpG, MSN-2NH2/CpG and MSN-3NH2/CpG complexes were investigated in detail. The results showed that three kinds of aminated-MSN-based CpG ODN delivery systems had no cytotoxicity to RAW264.7 cells, and binding of CpG ODN to MSN-NH2, MSN-2NH2 and MSN-3NH2 nanoparticles enhanced the serum stability of CpG ODN due to protection by the nanoparticles. However, three aminated MSN-based CpG ODN delivery systems exhibited different CpG ODN delivery efficiency, and MSN-NH2/CpG complexes had the highest ability to induce IL-6 secretion.

Koo JE, Shin SW, Um SH, Lee JY. X-shaped DNA potentiates therapeutic efficacy in colitis-associated colon cancer through dual activation of TLR9 and inflammasomes. Mol Cancer 2015; 14:104. [PMID: 25971982 PMCID: PMC4431032 DOI: 10.1186/s12943-015-0369-2] [Citation(s) in RCA: 15] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/16/2015] [Accepted: 04/21/2015] [Indexed: 12/20/2022] Open
Abstract
Background Immunotherapy has been extensively pursed as a promising strategy for the treatment of cancer. Pattern-recognition receptors (PRRs) play important roles in triggering activation of innate and adaptive immunity. Therefore, agents that stimulate PRRs could be useful for cancer immunotherapy. We developed two kinds of X-shaped double-stranded oligodeoxynucleotides (X-DNA), a single unit of X-DNA (XS-DNA) composed of four strands of DNA and a ligated X-DNA complex (XL-DNA) formed by crosslinking each XS-DNA to the other, and investigated if they had immunostimulatory activity and could be applied to anti-cancer immunotherapy. Methods Activation of MAPKs and NF-κB was determined by immunoblotting in bone marrow-derived primary dendritic cells (BMDCs). Immune cytokines and co-stimulatory molecules were measured by ELISA and flow cytometry analysis. Anti-cancer efficacy was examined in an azoxymethane/dextran sulfate sodium-induced colitis-associated colon cancer mouse model. Association of X-DNA and TLR9 was determined by co-immunoprecipitation followed by immunoblotting. The involvement of TLR9 and inflammasomes was determined using TLR9- or caspase-1-deficient BMDCs. Inflammasome activation was examined by degradation of pro-caspase-1 to caspase-1 and cleavage of pro-IL-1β to IL-1β in BMDCs. Results XL-DNA and XS-DNA induced activation of MAPKs and NF-κB and production of immune cytokines and co-stimulatory molecules in BMDCs. BMDCs stimulated by XL-DNA induced differentiation of naïve CD4+ T cells to TH1 cells. Intravenous injection of XL-DNA into mice resulted in increased serum IFN-γ and IL-12 levels, showing in vivo efficacy of XL-DNA to activate TH1 cells and dendritic cells. XL-DNA greatly enhanced the therapeutic efficacy of doxorubicin, an anti-cancer drug, in colitis-associated colon cancer. XL-DNA directly associated with TLR9. In addition, immunostimulatory activities of X-DNA were abolished in TLR9-deficient dendritic cells. Furthermore, X-DNA induced caspase-1 degradation and IL-1β secretion in BMDCs, which were abolished in caspase-1-deficient cells. Conclusions X-DNA induced the activation of dendritic cells as shown by the expression of immune-cytokines and co-stimulatory molecules, resulting in the differentiation of TH1 cells, mediated through dual activation of TLR9 and inflammasomes. X-DNA represents a promising immune adjuvant that can enhance the therapeutic efficacy of anti-cancer drugs by activating PRRs.

Abstract
Drug delivery carriers have been popularly employed to improve solubility, stability, and efficacy of chemical and biomolecular drugs. Despite the rapid progress in this field, it remains a great challenge to develop an ideal carrier with minimal cytotoxicity, high biocompatibility and intelligence for targeted controlled release. The emergence of DNA nanotechnology offers unprecedented opportunities in this regard. Due to the unparalleled self-recognition properties of DNA molecules, it is possible to create numerous artificial DNA nanostructures with well-defined structures and DNA nanodevices with precisely controlled motions. More importantly, recent studies have proven that DNA nanostructures possess greater permeability to the membrane barrier of cells, which pave the way to developing new drug delivery carriers with nucleic acids, are summarized. In this Concept, recent advances on the design and fabrication of both static and dynamic DNA nanostructures, and the use of these nanostructures for the delivery of various types of drugs, are highlighted. It is also demonstrated that dynamic DNA nanostructures provide the required intelligence to realize logically controlled drug release.

Abstract
Graphene oxide (GO) has attracted tremendous research interest due to its excellent electrical, thermal, and mechanical properties. Here, we apply the polyethylene glycol (PEG) and polyethylenimine (PEI) dual-polymer-functionalized GO (GO-PEG-PEI) as the carrier for efficient CpG delivery. GO-PEG-PEI can significantly promote the production of proinflammatory cytokines and enhance the immunostimulatory effect of CpG. In addition, the NIR optical absorbance of GO-PEG-PEI has been further applied to control the immunostimulatory activity of CpG ODNs, showing remarkably enhanced immunostimulation responses under NIR laser irradiation, owing to the photothermally induced local heating that accelerated intracellular trafficking of nanovectors. This is the first demonstration of using the photothermally enhanced intracellular transportation of nanocarriers for light-controllable CpG delivery. In vivo assay demonstrates that the GO-PEG-PEI-CpG complex provides synergistic photothermal and immunological effects under laser irradiation for cancer treatment, which shows the highest efficiency in tumor reduction, implying the excellent therapeutic efficacy of the GO-PEG-PEI-CpG complex in cancer therapy.
