Abstract
Cell-free protein synthesis (CFPS) has the advantage of rapid expression of proteins and has been widely implemented in synthetic biology and protein engineering. However, the critical problem limiting CFPS industrial application is its relatively high cost, which partly attributes to the overexpense of single-use DNA templates. Hydrogels provide a possible solution because they can preserve and reutilize the DNA templates in CFPS and have great potential in elevating the protein production yield of the CFPS. Here, we presented a low-cost hybrid hydrogel simply prepared with polyethylene glycol diacrylate (PEGDA) and DNA, which is capable of high-efficient and repeated protein synthesis in CFPS. Parameters governing protein production specific to hybrid hydrogels were optimized. Structures and physical properties of the hybrid hydrogel were characterized. Transcription and expression kinetics of solution phase system and gel phased systems were investigated. The results showed that PEGDA/DNA hydrogel can enhance the protein expression of the CFPS system and enable a repeated protein production for tens of times. This PEGDA/DNA hybrid hydrogel can serve as a recyclable gene carrier for either batch or continuous protein expression, and paves a path toward more powerful, scalable protein production and cell-free synthetic biology.

Development of RNA/DNA Hydrogel Targeting Toll-Like Receptor 7/8 for Sustained RNA Release and Potent Immune Activation. Molecules 2020; 25:molecules25030728.

Abstract
Guanosine- and uridine-rich single-stranded RNA (GU-rich RNA) is an agonist of Toll-like receptor (TLR) 7 and TLR8 and induces strong immune responses. A nanostructured GU-rich RNA/DNA assembly prepared using DNA nanotechnology can be used as an adjuvant capable of improving the biological stability of RNA and promoting efficient RNA delivery to target immune cells. To achieve a sustained supply of GU-rich RNA to immune cells, we developed a GU-rich RNA/DNA hydrogel (RDgel) using nanostructured GU-rich RNA/DNA assembly, from which GU-rich RNA can be released in a sustained manner. A hexapod-like GU-rich RNA/DNA nanostructure, or hexapodRD6, was designed using a 20-mer phosphorothioate-stabilized GU-rich RNA and six phosphodiester DNAs. Two sets of hexapodRD6 were mixed to obtain RDgel. Under serum-containing conditions, GU-rich RNA was gradually released from the RDgel. Fluorescently labeled GU-rich RNA was efficiently taken up by DC2.4 murine dendritic cells and induced a high level of tumor necrosis factor-α release from these cells when it was incorporated into RDgel. These results indicate that the RDgel constructed using DNA nanotechnology can be a useful adjuvant in cancer therapy with sustained RNA release and high immunostimulatory activity.

Abstract
OBJECTIVES Posttransplant cardiac allograft vasculo-pathy affects long-term survival after heart transplant. Because cardiac transplant recipients do not feel angina pectoris as a result of denervation of the transplanted heart graft, early diagnosis is difficult. The Gensini score, a widely used and simple scoring system, can determine the severity of coronary artery disease by angiography. Although this system has been widely used to evaluate natural coronary atherosclerosis, its use in heart transplant recipients has not been studied. Here, we evaluated cardiac allograft vasculo-pathy using the Gensini score. MATERIALS AND METHODS We retrospectively analyzed 105 heart transplant patients seen between February 2004 and April 2018, including their immunosuppressive therapies. The Gensini score was calculated to determine severity score for each coronary stenosis according to degree of luminal narrowing and location. RESULTS Of 105 heart transplant patients, 21 were diagnosed with cardiac allograft vasculopathy. Most patients received tacrolimus, prednisolone, and mycophenolate mofetil as standard therapy. Of 63 included patients, 21 (33.3%) showed cardiac allograft vasculopathy on coronary angiography. In accordance with the International Society of Heart and Lung Transplantation rating system, 42 of 63 patients (66.6%) were rated as 0 (no detectable angiographic lesions). Mean Gensini score was 34.8 ± 26. In the 21 patients with cardiac allograft vasculopathy, Gensini score showed mild cardiac allograft vas-culopathy (score ≤ 10) in 8 patients (38%), moderate (score > 10 and ≤ 40) in 6 patients (28.5%), and severe (score > 40) in 7 patients (33.3%). Angiographic coronary artery disease burden using Gensini was strongly correlated with cardiac allograft vasculopathy severity. CONCLUSIONS The Gensini score could provide valid assessment of cardiac allograft vasculopathy burden for use in clinical practice. However, more research is needed to identify and treat cardiac allograft vasculopathy for successful long-term survival of heart transplant patients.

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
Nucleic acids have both extensive physiological function and structural potential, rendering them quintessential engineering biomaterials. As carriers of precisely-tunable genetic information, both DNA and RNA can be synthetically generated to form a myriad of structures and to transmit specific genetic code. Importantly, recent studies have shown that DNA and RNA, both in their native and engineered forms, can function as potent regulators of innate immunity, capable of initiating and modulating immune responses. In this review, we highlight recent advances in biomaterials inspired by the various interactions of nucleic acids and the immune system. We discuss key advances in self-assembled structures based on exogenous nucleic acids and engineering approaches to apply endogenous nucleic acids as found in immunogenic cell death and extracellular traps. In addition, we discuss new strategies to control dinucleotide signaling and provide recent examples of biomaterials designed for cancer immunotherapy with STING agonists.

Abstract
Clinical need for treating allergic conjunctivitis (AC) is rapidly increasing. However, AC-relevant anti-inflammatory compounds are generally difficult to solubilize in water, thus limiting their therapeutic potential. Solubility-improved eye drop formulations of these compounds have poor bioavailability and a short retention time in ophthalmic tissues. Herein, we report a DNA/poly(lactic-co-glycolicacid) (PLGA) hybrid hydrogel (HDNA) for water-insoluble ophthalmic therapeutic delivery. PLGA pre-encapsulation enables loading of water-insoluble therapeutics. HDNA's porous structure is capable of sustained delivery of therapeutics. Dexamethasone (DEX), with demonstrated activities in attenuating inflammatory symptom in AC, was used as a model system. The designed HDNA hybrid hydrogels significantly improved the DEX accumulation and mediated the gradual DEX release in ophthalmic cells and tissues. Using the HDNA-DEX complexes, potent efficacy in two animal models of AC was acquired. Given this performance, demonstrable biocompatibility, and biodegradability of DNA hydrogel, the HDNA-based ophthalmic therapeutic delivery system enables novel treatment paradigms, which will have widespread applications in the treatment of various eye diseases.

Abstract
Macroscale biomaterials, such as preformed implantable scaffolds and injectable soft materials, possess powerful synergies with anti-cancer immunotherapies. Immunotherapies on their own typically have poor delivery properties, and often require repeated high-dose injections that result in serious off-tumor effects and/or limited efficacy. Rationally designed biomaterials allow for discrete localization and controlled release of immunotherapeutic agents, and have been shown in a large number of applications to improve outcomes in the treatment of cancers via immunotherapy. Among various strategies, macroscale biomaterial delivery systems can take the form of robust tablet-like scaffolds that are surgically implanted into a tumor resection site, releasing programmed immune cells or immunoregulatory agents. Alternatively they can be developed as soft gel-like materials that are injected into solid tumors or sites of resection to stimulate a potent anti-tumor immune response. Biomaterials synthesized from diverse components such as polymers and peptides can be combined with any immunotherapy in the modern toolbox, from checkpoint inhibitors and stimulatory adjuvants, to cancer antigens and adoptive T cells, resulting in unique synergies and improved therapeutic efficacy. The field is growing rapidly in size as publications continue to appear in the literature, and biomaterial-based immunotherapies are entering clinical trials and human patients. It is unarguably an exciting time for cancer immunotherapy and biomaterial researchers, and further work seeks to understand the most critical design considerations in the development of the next-generation of immunotherapeutic biomaterials. This review will discuss recent advances in the delivery of immunotherapies from localized biomaterials, focusing on macroscale implantable and injectable systems. STATEMENT OF SIGNIFICANCE: Anti-cancer immunotherapies have shown exciting clinical results in the past few decades, yet they suffer from a few distinct limitations, such as poor delivery kinetics, narrow patient response profiles, and systemic side effects. Biomaterial systems are now being developed that can overcome many of these problems, allowing for localized adjuvant delivery, focused dose concentrations, and extended therapy presentation. The field of biocompatible carrier materials is uniquely suited to be combined with immunotherapy, promising to yield significant improvements in treatment outcomes and clinical care. In this review, the first pioneering efforts and most recent advances in biomaterials for immunotherapeutic applications are explored, with a specific focus on implantable and injectable biomaterials such as porous scaffolds, cryogels, and hydrogels.

Abstract
We report a novel and potential wound dressing hydrogel based on DNA and a green industrial microbiocide tetrakis (hydroxymethyl) phosphonium sulfate (THPS) via one-pot self-assembly. Intermolecular electrostatic interaction and hydrogen bonding between DNA and THPS together drive the formation of the adhesive DNT (DNA+THPS) hydrogel, featuring with self-healing, shear-thinning and injectability. This wound dressing hydrogel possesses broad-spectrum antibacterial ability with low cytotoxicity to L929 cells. Furthermore, the wound dressing can reduce the risk of wound infection by releasing THPS to suppress bacterial spread and accelerate wound healing. The low cost and simple preparation may make the hydrogel attractive in biomedical applications and could be a good reference to others.

Abstract
SIGNIFICANCE Nanomedicine is an application of nanotechnology that provides solutions to unmet medical challenges. The unique features of nanoparticles, such as their small size, modifiable components, and diverse functionality, make them attractive and suitable materials for novel diagnostic, therapeutic, or theranostic applications. Cardiovascular diseases (CVDs) are the major cause of noncommunicable illness in both developing and developed countries. Nanomedicine offers novel theranostic options for the treatment of CVDs. Recent Advances: Many innovative nanoparticles to target reactive oxygen species (ROS) have been developed. In this article, we review the characteristics of nanoparticles that are responsive to ROS, their limitations, and their potential clinical uses. Significant advances made in diagnosis of atherosclerosis and treatment of acute coronary syndrome using nanoparticles are discussed. CRITICAL ISSUES Although there is a tremendous potential for the nanoparticle applications in medicine, their safety should be considered while using in humans. We discuss the challenges that may be encountered with some of the innovative nanoparticles used in CVDs. FUTURE DIRECTIONS The unique properties of nanoparticles offer novel diagnostic tool and potential therapeutic strategies. However, nanomedicine is still in its infancy, and further in-depth studies are needed before wide clinical application is achieved.

Conventional drug delivery approaches are plagued by issues pertaining to systemic toxicity and repeated dosing. Hydrogels offer convenient drug delivery vehicles to ensure these disadvantages are minimized and the therapeutic benefits from the drug are optimized. With exquisitely tunable physical properties that confer them great controlled drug release features and the merits they offer for labile drug protection from degradation, hydrogels emerge as very efficient drug delivery systems. The versatility and diversity of the hydrogels extend their applications beyond targeted drug delivery also to wound dressings, contact lenses and tissue engineering to name but a few. They are 90% water, and highly porous to accommodate drugs for delivery and facilitate controlled release. Herein we discuss hydrogels and how they could be manipulated for targeted drug delivery applications. Suitable examples from the literature are provided that support the recent advancements of hydrogels in targeted drug delivery in diverse disease areas and how they could be suitably modified in very different ways for achieving significant impact in targeted drug delivery. With their enormous amenability to modification, hydrogels serve as promising delivery vehicles of therapeutic molecules in several disease conditions, including cancer and diabetes.

Abstract
Man-made DNA materials hold the potential to modulate specific immune pathways toward immunoactivating or immunosuppressive cascades. DNA-based biomaterials introduce DNA into the extracellular environment during implantation or delivery, and subsequently intracellularly upon phagocytosis or degradation of the material. Therefore, the immunogenic functionality of biological and synthetic extracellular DNA should be considered to achieve desired immune responses. In vivo, extracellular DNA from both endogenous and exogenous sources holds immunoactivating functions which can be traced back to the molecular features of DNA, such as sequence and length. Extracellular DNA is recognized as damage-associated molecular patterns (DAMPs), or pathogen-associated molecular patterns (PAMPs), by immune cell receptors, activating either proinflammatory signaling pathways or immunosuppressive cell functions. Although extracellular DNA promotes protective immune responses during early inflammation such as bacterial killing, recent advances demonstrate that unresolved and elevated DNA concentrations may contribute to the pathogenesis of autoimmune diseases, cancer, and fibrosis. Therefore, addressing the immunogenicity of DNA enables immune responses to be engineered by optimizing their activating and suppressive performance per application. To this end, emerging biology relevant to the generation of extracellular DNA, DNA sensors, and its role concerning existing and future synthetic DNA biomaterials are reviewed.

Abstract
Injectable hydrogels present several advantages over prefabricated scaffolds including ease of delivery, shear-thinning property, and broad applicability in the fields of drug delivery and tissue engineering. Here, we report an approach to develop injectable hydrogels with sustained drug release properties, exploiting the chemical nature of the DNA backbone and silicate nanodisks. A two-step gelation method is implemented for generating a combination of noncovalent network points, leading to a physically cross-linked hydrogel. The first step initiates the development of an interconnected structure by utilizing DNA denaturation and rehybridization mechanism to form hydrogen bonds between complementary base pairs of neighboring DNA strands. The anisotropic charge distribution of two-dimensional silicate nanodisks (nSi) makes them an active center in the second step of the gelation process. Silicate nanodisks create additional network points via attractive electrostatic interactions with the DNA backbone, thereby enhancing the mechanical resilience of the formulated hydrogel. The thermally stable hydrogels displayed an increase in elasticity and yield stress as a function of nSi concentration. They were able to form self-supporting structures post injection due to their rapid recovery after removal of cyclic stress. Moreover, the presence of nanosilicate was shown to modulate the release of a model osteogenic drug dexamethasone (Dex). The bioactivity of released Dex was confirmed from in vitro osteogenic differentiation of human adipose stem cells and in vivo bone formation in a rat cranial bone defect model. Overall, our DNA-based nanocomposite hydrogel obtained from a combination of noncovalent network points can serve as an injectable material for bone regeneration and carrier for sustained release of therapeutics.

Aptamer Functionalized DNA Hydrogel for Wise-Stage Controlled Protein Release. APPLIED SCIENCES-BASEL 2018.

Abstract
With the simple functionalization method and good biocompatibility, an aptamer-integrated DNA hydrogel is used as the protein delivery system with an adjustable release rate and time by using complementary sequences (CSs) as the biomolecular trigger. The aptamer-functionalized DNA hydrogel was prepared via a one-pot self-assembly process from two kinds of DNA building blocks (X-shaped and L-shaped DNA units) and a single-stranded aptamer. The gelling process was achieved under physiological conditions within one minute. In the absence of the triggering CSs, the aptamer grafted in the hydrogel exhibited a stable state for protein-specific capture. While hybridizing with the triggering CSs, the aptamer is turned into a double-stranded structure, resulting in the fast dissociation of protein with a wise-stage controlled release program. Further, the DNA hydrogel with excellent cytocompatibility has been successfully applied to human serum, forming a complex matrix. The whole process of protein capture and release were biocompatible and could not refer to any adverse factor of the protein or cells. Thus, the aptamer-functionalized DNA hydrogel will be a good candidate for controlled protein delivery.

Abstract
Our previous study demonstrated that the incorporation of a tumor antigen into a self-assembling DNA hydrogel, comprised of a DNA containing un-methylated cytosine-phosphate-guanine (CpG) dinucleotides (CpG DNA), efficiently induced antigen-specific tumor immunity after intra-tumoral injection into tumor-bearing mice. We hypothesized that the additional incorporation of immune cells, the target for the antigen and immunostimulatory CpG DNA, would increase the antitumor response. To prove this, immune cells were also encapsulated into the CpG DNA hydrogel and delivered along with the antigen. Mouse dendritic DC2.4 cells maintained their form even after incorporation into the DNA hydrogel. The incorporation of mouse macrophage-like J774.1 cells and RAW264.7 cells into CpG DNA hydrogel did not significantly affect their viability. J774.1, RAW264.7, DC2.4, and mouse bone marrow-derived dendritic cells (BMDCs) were efficiently activated when incorporated into the CpG DNA hydrogel. The CpG DNA hydrogel incorporated with both the tumor antigen and BMDCs effectively induced antigen-specific immune responses, and retarded tumor growth following intradermal administration before and after tumor inoculation without severe local and systemic adverse events. These data indicate that the combined delivery of a tumor antigen and immune cells using an immunostimulatory CpG DNA hydrogel is effective in inducing antigen-specific antitumor immunity.

Abstract
The past decade has witnessed the accelerating development of immunotherapies for cancer treatment. Immune checkpoint blockade therapies and chimeric antigen receptor (CAR)-T cell therapies have demonstrated clinical efficacy against a variety of cancers. However, issues including life-threatening off-target side effects, long processing times, limited patient responses and high cost still limit the clinical utility of cancer immunotherapies. Biomaterial carriers of these therapies, though, enable one to troubleshoot the delivery issues, amplify immunomodulatory effects, integrate the synergistic effect of different molecules and, more importantly, home and manipulate immune cells in vivo. In this Review, we will analyse thus-far developed immunomaterials for targeted modulation of dendritic cells, T cells, tumour-associated macrophages, myeloid-derived suppressor cells, B cells and natural killer cells, and summarize the promises and challenges of cell-targeted immunomodulation for cancer treatment.

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
DNA encodes the genetic information; recently, it has also become a key player in material science. Given the specific Watson-Crick base-pairing interactions between only four types of nucleotides, well-designed DNA self-assembly can be programmable and predictable. Stem-loops, sticky ends, Holliday junctions, DNA tiles, and lattices are typical motifs for forming DNA-based structures. The oligonucleotides experience thermal annealing in a near-neutral buffer containing a divalent cation (usually Mg2+ ) to produce a variety of DNA nanostructures. These structures not only show beautiful landscape, but can also be endowed with multifaceted functionalities. This Review begins with the fundamental characterization and evolutionary trajectory of DNA-based artificial structures, but concentrates on their biomedical applications. The coverage spans from controlled drug delivery to high therapeutic profile and accurate diagnosis. A variety of DNA-based materials, including aptamers, hydrogels, origamis, and tetrahedrons, are widely utilized in different biomedical fields. In addition, to achieve better performance and functionality, material hybridization is widely witnessed, and DNA nanostructure modification is also discussed. Although there are impressive advances and high expectations, the development of DNA-based structures/technologies is still hindered by several commonly recognized challenges, such as nuclease instability, lack of pharmacokinetics data, and relatively high synthesis cost.

Abstract
Immunotherapy is believed to be an ideal method to treat cancer because it can break the immunotolerance of tumor and induce robust immunoresponse. However, constructing a wide antigen-adaptive, easy-handling, and biodegradable system that can recruit and activate antigen-presenting cells (APCs) much effectively is still a challenge. Herein, we show an injectable DNA supramolecular hydrogel vaccine (DSHV) system which could efficiently recruit and activate APCs in vitro and in vivo. The in vitro processes have been visualized by fluorescence microscopy. Through intraperitoneal or subcutaneous injection, the DSHV system can mimic the function of a lymph node where the APCs are recruited and activated by the high local concentration of cytosine-phosphate-guanine. Subsequently, strong immune response and obvious antitumor effects have been obtained. Our findings demonstrated that the DSHV system could serve as a general platform for tumor vaccination and benefit the personalized cancer therapy in the near future.

Abstract
Conventional class B cytosine-guanine (CpG) (CpG-B) oligodeoxynucleotide (ODNs) consisting of a single-stranded (ss) phosphorothioate (PT) backbone (ss CpG-B-PT) is converted from a proinflammatory cytokine inducer to a type-I interferon (IFN) inducer when complexed with cationic materials. In this study, we designed ss CpG-B and double-stranded (ds) CpG-B ODNs with a phosphodiester (PD) backbone (ss CpG-B-PD and ds CpG-B-PD, respectively) that became type-I IFN inducers upon complexation with Lipofectamine 2000 (Lipo), a cationic liposome. The ds CpG-B-PD complex induced higher IFN-β expression in mouse macrophage-like RAW264 cells than ss CpG-B-PD and ss CpG-B-PT complexes. The fold induction of IFN-β increased with the number of CpG motifs in ds CpG-B-PD, and a complex of ds CpG-B-PD consisting of 72 base pairs with nine CpG motifs (ds CpG-B72-PD) and Lipo showed the highest capacity to induce IFN-β. The materials and method used for complexation influenced the degree of IFN-β induction: ds CpG-B72-PD entrapped by calcium phosphate (CaP) (ds CpG-B72-PD/CaP) showed a higher induction capacity than ds CpG-B72-PD adsorbed onto the CaP surface. Entrapment of ds CpG-B72-PD by CaP also enhanced the induction of the proinflammatory cytokine interleukin-12. Vaccinating mice with ds CpG-B72-PD/CaP in conjunction with ovalbumin (OVA) increased the ratios of OVA-specific CD8+ T cells to total CD8+ T cells in peripheral blood and of OVA-specific IgG2a associated with helper T (Th)1 cells to OVA-specific IgG1 associated with Th2 cells. These results indicate that ds CpG-B72-PD/CaP is an effective vaccine adjuvant that can activate both cellular and Th1-type humoral immune responses.

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
Understanding the impact of incorporating new physical and chemical features in oligomeric DNA mimics, termed generally as "oligonucleic acids" (ONAs), on their structure and thermodynamics will be beneficial in designing novel materials for a variety of applications. In this work, we conduct coarse-grained molecular simulations of ONA-star polymer conjugates with varying ONA backbone flexibility, ONA backbone charge, and number of arms in the star polymer at a constant ONA strand volume fraction to elucidate the effect of these design parameters on the thermodynamics and assembly of multi-arm ONA-star polymer conjugates. We quantify the thermo-reversible behavior of the ONA-star polymer conjugates by quantifying the hybridization of the ONA strands in the system as a function of temperature (i.e. melting curve). Additionally, we characterize the assembly of the ONA-star polymer conjugates by tracking cluster formation and percolation as a function of temperature, as well as cluster size distribution at temperatures near the assembly transition region. The key results are as follows. The melting temperature (Tm) of the ONA strands decreases upon going from a neutral to a charged ONA backbone and upon increasing flexibility of the ONA backbone. Similar behavior is seen for the assembly transition temperature (Ta) with varying ONA backbone charge and flexibility. While the number of arms in the ONA-star polymer conjugate has a negligible effect on the ONA Tm in these systems, as the number of ONA-star polymer arms increase, the assembly temperature Ta increases and local ordering in the assembled state improves. By understanding how factors like ONA backbone charge, backbone flexibility, and ONA-star polymer conjugate architecture impact the behavior of ONA-star polymer conjugate systems, we can better inform how the selection of ONA chemistry will influence resulting ONA-star polymer assembly.

Abstract
Our previous study indicates that cationization of an antigen is effective for sustained release of both immunostimulatory DNA containing unmethylated cytosine-phosphate-guanine (CpG) dinucleotides, or CpG DNA, and antigen from a DNA hydrogel. Another approach to sustained antigen release would increase the applicability and versatility of the system. In this study, a hydrophobic interaction-based sustained release system of ovalbumin (OVA), a model antigen, from immunostimulatory CpG DNA hydrogel is developed by the use of cholesterol-modified DNA and urea-denatured OVA (udOVA). Cholesterol-modified DNA forms a hydrogel, Dgel(chol), and induces IL-6 mRNA expression in mouse skin after intradermal injection, as DNA without cholesterol does. Cholesterol-modified DNA associated with OVA and denaturation of OVA using urea increases the interaction. The release of udOVA from Dgel(chol) is significantly slower than that from DNA hydrogel with no cholesterol, Dgel. Moreover, intratumoral injections of udOVA/Dgel(chol) significantly inhibit the growth of EG7-OVA tumors in mice. These results indicate that sustained release of antigen from Dgel can be achieved by the combination of urea denaturation and cholesterol modification, and retardation of antigen release is effective to induce antigen-specific cancer immunity.

Abstract
A new class of hydrogels utilizing DNA (DNA quadruplex gel) has been constructed by directly and symmetrically coupling deoxynucleotide phosphoramidite monomers to the ends of polyethylene glycols (PEGs) in liquid phase, and using the resulting DNA-PEG-DNA triblock copolymers as macromonomers. Elongation of merely four deoxyguanosine residues on PEG, which produces typically ≈10 grams of desired DNA-PEG conjugates in one synthesis, resulted in intelligent and biodegradable hydrogels utilizing DNA quadruplex formation, which are responsive to various input signals such as Na+ , K+ , and complementary DNA strand. Gelation of DNA quadruplex gels takes place within a few seconds upon the addition of a trigger, enabling free formation just like Ca+ -alginate hydrogels or possible application as an injectable polymer (IP) gel. The obtained hydrogels show good thermal stability and rheological properties, and even display self-healing ability.

Abstract
Biotemplated nanomaterials offer versatile functionality for multimodal imaging, biosensing, and drug delivery. There remains an unmet need for traceable and biocompatible nanomaterials that can be synthesized in a precisely controllable manner. Here, we report self-assembled quantum dot DNA hydrogels that exhibit both size and spectral tunability. We successfully incorporate DNA-templated quantum dots with high quantum yield, long-term photostability, and low cytotoxicity into a hydrogel network in a single step. By leveraging DNA-guided interactions, we introduce multifunctionality for a variety of applications, including enzyme-responsive drug delivery and cell-specific targeting. We report that quantum dot DNA hydrogels can be used for delivery of doxorubicin, an anticancer drug, to increase potency 9-fold against cancer cells. This approach also demonstrated high biocompatibility, trackability, and in vivo therapeutic efficacy in mice bearing xenografted breast cancer tumors. This work paves the way for the development of new tunable biotemplated nanomaterials with multiple synergistic functionalities for biomedical applications. The development of nanomaterials for imaging and drug delivery has been of great interest to the field. Here, the authors synthesized multifunctional enzyme-responsive hydrogels with self-assembling quantum dots for nucleic acid and drug delivery as well as having imaging capability.

Abstract
Cytosine-phosphate-guanine (CpG) DNA is known to increase the potency of vaccines. Here, in vitro and in vivo stimulation of toll-like receptor 9 by CpG DNA incorporated into polypod-like DNA nanostructures was evaluated by measuring the levels of tumor necrosis factor alpha released from macrophage-like RAW 264.7 cells and plasma interleukin (IL)-12p40 in vivo following intravenous injection into mice. Phosphodiester CpG1668 was selected as the CpG DNA, and tripodna and hexapodna, which were CpG1668-containing tripod and hexapod-like DNA nanostructures, respectively, were designed. CpG-tripodna and CpG-hexapodna induced tumor necrosis factor alpha release from RAW 264.7 cells about 10- and ∼30-fold higher than single-stranded CpG1668 (CpG-SS). Moreover, in all cases examined, plasma IL-12p40 concentrations increased after intravenous injection into mice, with peak levels depending on the samples and the doses. The area under the plasma concentration-time curves indicated that the CpG-hexapodna was approximately 20-fold more efficient in inducing IL-12p40 production than CpG-SS. The efficiency of CpG-tripodna and CpG-hexapodna to increase the potency of CpG-SS in vivo was comparable to that observed in cultured RAW 264.7 cells. These results provide experimental evidence that in vitro studies can be used to estimate the in vivo immunostimulatory activity of CpG DNA incorporated into DNA nanostructures.

Abstract
DNA hydrogel has aroused widespread attention because of its unique properties. In this work, the DNA-modified magnetic nanoparticles were integrated into the mainframe of DNA hydrogel, resulting in DNA-MNP hydrogel. Under the magnetic field, this hydrogel can be remotely deformed into various shapes, driven to jump between two planes and even climb the hill. By applying various triggers, such as temperature, enzyme, and magnetic field, DNA-MNP hydrogel can specifically undergo sol-gel transition. This work not only imparts DNA hydrogel with a new fold of property but also opens a unique platform of such smart materials for its further applications.

Abstract
Unmethylated cytosine-guanine dinucleotide-containing oligodeoxynucleotides (CpG ODNs), which are synthetic agonists of Toll-like receptor 9 (TLR9), activate humoral and cellular immunity and are being developed as vaccine adjuvants to prevent or treat cancers, infectious diseases, and allergies. Free CpG ODNs have been used in many clinical trials implemented to verify their effects. However, recent research has reported that self-assembled CpG ODNs, protein/peptide–CpG ODN conjugates, and nanomaterial–CpG ODN complexes demonstrate higher adjuvant effects than free CpG ODNs, owing to their improved uptake efficiency into cells expressing TLR9. Moreover, protein/peptide–CpG ODN conjugates and nanomaterial–CpG ODN complexes are able to deliver CpG ODNs and antigens (or allergens) to the same types of cells, which enables a higher degree of prophylaxis or therapeutic effect. In this review, the author describes recent trends in the research and development of CpG ODN nanomedicines containing self-assembled CpG ODNs, protein/peptide–CpG ODN conjugates, and nanomaterial–CpG ODN complexes, focusing mainly on the results of preclinical and clinical studies.

Abstract
This paper reports the in vitro characterization of the interaction between the phosphate groups of DNA and the protonated species of drugs with basic groups through the determination of the affinity constants, the reversibility of the interaction, and the effect on the secondary structure of the macromolecule. Affinity constants of the counterionic condensation DNA–drug were in the order of 106. The negative electrokinetic potential of DNA decreased with the increase of the proportion of loading drugs. The drugs were slowly released from the DNA–drug complexes and had release kinetics consistent with the high degree of counterionic condensation. The circular dichroism profile of DNA was not modified by complexation with atenolol, lidocaine, or timolol, but was significantly altered by the more lipophilic drugs benzydamine and propranolol, revealing modifications in the secondary structure of the DNA. The in vitro characterization of such interactions provides a physicochemical basis that would contribute to identify the effects of this kind of drugs in cellular cultures, as well as side effects observed under their clinical use. Moreover, this methodology could also be projected to the fields of intracellular DNA transfection and the use of DNA as a carrier of active drugs.

Abstract
Nucleic acids are biologically active materials, and chemically modified nucleic acids are now being used in nucleic acid drugs. DNA, one of the two types of nucleic acids, can also be used as a material to construct DNA-based delivery systems, such as DNA hydrogel, for therapeutic compounds. Use of chemically modified nucleic acids would greatly increase the therapeutic potency of such DNA-based delivery systems. However, attention should be paid to the differences in the physicochemical properties of natural and chemically modified nucleic acids. Another, more important concern for chemically modified nucleic acids is the high cost of their synthesis. Reducing the cost of synthesizing oligonucleotides, and especially ones with chemically modified nucleic acids, is crucial to the expanded use of both nucleic acid drugs and DNA-based delivery systems.

Abstract
Hemocompatibility and cytocompatibility of biomaterials codetermine the success of tissue engineering applications. DNA, the natural component of our cells, is an auspicious biomaterial for the generation of designable scaffolds with tailorable characteristics. In this study, a combination of rolling circle amplification and multiprimed chain amplification is used to generate hydrogels at centimeter scale consisting solely of DNA. Using an in vitro rotation model and fresh human blood, the reaction of the hemostatic system on DNA hydrogels is analyzed. The measurements of hemolysis, platelets activation, and the activation of the complement, coagulation, and neutrophils using enzyme-linked immunosorbent assays demonstrate excellent hemocompatibility. In addition, the cytocompatibility of the DNA hydrogels is tested by indirect contact (agar diffusion tests) and material extract experiments with L929 murine fibroblasts according to the ISO 10993-5 specifications and no negative impact on the cell viability is detected. These results indicate the promising potential of DNA hydrogels as biomaterials for versatile applications in the field of regenerative medicine.

Abstract
Sustained antigen delivery using incomplete Freund's adjuvant (IFA) can induce strong, long-term immune response, but it can also cause severe side effects. Here we describe an injectable, phospholipid-based phase separation gel (PPSG) that readily transforms in situ into a drug depot. PPSG loaded with the model antigen ovalbumin (OVA) supported sustained OVA release in mice that lasted nearly one month. Immunizing mice with a single injection of PPSG/OVA elicited a strong and persistent increase in titers of OVA-specific IgG, IgG1 and IgG2a. Co-administering CpG-ODN further increased antibody titers. Such co-administration recruited dendritic cells to injection sites and activated dendritic cells in the draining lymph nodes. Moreover, immunization with PPSG/OVA/CpG resulted in potent memory antibody responses and high frequency of memory T cells. Remarkably, PPSG/OVA/CpG was associated with much lower toxicity at injection sites than IFA/OVA/CpG, and it showed no systemic toxicity such as to lymph nodes or spleen. These findings illustrate the potential of injectable PPSG for sustained, minimally toxic delivery of antigens and adjuvants.

Abstract
Hydrogels are crosslinked hydrophilic polymers that can absorb a large amount of water. By their hydrophilic, biocompatible and highly tunable nature, hydrogels can be tailored for applications in bioanalysis and biomedicine. Of particular interest are DNA-based hydrogels owing to the unique features of nucleic acids. Since the discovery of the DNA double helical structure, interest in DNA has expanded beyond its genetic role to applications in nanotechnology and materials science. In particular, DNA-based hydrogels present such remarkable features as stability, flexibility, precise programmability, stimuli-responsive DNA conformations, facile synthesis and modification. Moreover, functional nucleic acids (FNAs) have allowed the construction of hydrogels based on aptamers, DNAzymes, i-motif nanostructures, siRNAs and CpG oligodeoxynucleotides to provide additional molecular recognition, catalytic activities and therapeutic potential, making them key players in biological analysis and biomedical applications. To date, a variety of applications have been demonstrated with FNA-based hydrogels, including biosensing, environmental analysis, controlled drug release, cell adhesion and targeted cancer therapy. In this review, we focus on advances in the development of FNA-based hydrogels, which have fully incorporated both the unique features of FNAs and DNA-based hydrogels. We first introduce different strategies for constructing DNA-based hydrogels. Subsequently, various types of FNAs and the most recent developments of FNA-based hydrogels for bioanalytical and biomedical applications are described with some selected examples. Finally, the review provides an insight into the remaining challenges and future perspectives of FNA-based hydrogels.

Abstract
Synthetic unmethylated cytosine-guanine (CpG) oligodeoxynucleotides are immunostimulatory motifs that have shown promise as vaccines or adjuvants for diseases such as cancers and infectious diseases. In the present work, novel immuno-nanoflowers (NFs), self-assembled from long DNA integrated with tandem CpG through rolling circle replication, were developed for efficient CpG delivery and protection from nuclease degradation. In a model of macrophage-like cells, the CpG NFs proved to be potent immunostimulators by triggering the proliferation of these immune cells, which, in turn, secreted immunostimulatory cytokines, including tumor necrosis factor α, interleukin-6, and interleukin-10. These results demonstrate the ability of CpG NFs to induce cancer cell apoptosis and necrosis.

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.
