    Non-viral gene delivery systems are typically designed vector systems with contradictory properties, namely sufficient stability before cellular uptake and instability to ensure the release of nucleic acid cargoes in the transcription process after being taken up into cells. We reported previously that poly-(L-lysine) terminally bearing a multi-arm PEG (maPEG-PLL) formed nanofiber-polyplexes that suppressed excessive DNA condensation via steric repulsion among maPEGs and exhibited effective transcriptional capability in PCR amplification experiments and a cell-free gene expression system. In this study, the reversible stabilization of a nanofiber-polyplex without impairing the effective transcriptional capability was investigated by introducing cross-links between the PLL side chains within the polyplex using a cross-linking reagent with disulfide (SS) bonds that can be disrupted under reducing conditions. In the presence of dextran sulfate and/or dithiothreitol, the stability of the polyplex and the reactivity of the pDNA were evaluated using agarose gel electrophoresis and real-time PCR. We succeeded in reversibly stabilizing nanofiber-polyplexes using dithiobis (succinimidyl propionate) (DSP) as the cross-linking reagent. The effect of the reversible stabilization was confirmed in experiments using cultured cells, and the DSP-crosslinked polyplexes exhibited gene expression superior to that of polyethyleneimine polyplexes, which are typical polyplexes.

  • Preparing Size-Controlled Liposomes Modified with Polysaccharide Derivatives for pH-Responsive Drug Delivery Applications

    The liposome particle size is an important parameter because it strongly affects content release from liposomes as a result of different bilayer curvatures and lipid packing. Earlier, we developed pH-responsive polysaccharide-derivative-modified liposomes that induced content release from the liposomes under weakly acidic conditions. However, the liposome used in previous studies size was adjusted to 100–200 nm. The liposome size effects on their pH-responsive properties were unclear. For this study, we controlled the polysaccharide-derivative-modified liposome size by extrusion through polycarbonate membranes having different pore sizes. The obtained liposomes exhibited different average diameters, in which the diameters mostly corresponded to the pore sizes of polycarbonate membranes used for extrusion. The amounts of polysaccharide derivatives per lipid were identical irrespective of the liposome size. Introduction of cholesterol within the liposomal lipid components suppressed the size increase in these liposomes for at least three weeks. These liposomes were stable at neutral pH, whereas the content release from liposomes was induced at weakly acidic pH. Smaller liposomes exhibited highly acidic pH-responsive content release compared with those from large liposomes. However, liposomes with 50 mol% cholesterol were not able to induce content release even under acidic conditions. These results suggest that control of the liposome size and cholesterol content is important for preparing stable liposomes at physiological conditions and for preparing highly pH-responsive liposomes for drug delivery applications.

    Nanotechnology has attracted increasing interest in various research fields for fabricating functional nanomaterials. In this study, we investigated the effect of poly(vinyl alcohol) (PVA) addition on the formation and thermoresponsive properties of poly(N-isopropyl acrylamide)-based nanogels in aqueous dispersion polymerizations. During dispersion polymerization, PVA appears to play three roles: (i) it bridges the generated polymer chains during polymerization, (ii) it stabilizes the formed polymer nanogels, and (iii) it regulates the thermoresponsive properties of the polymer nanogels. By regulating the bridging effect of PVA via changing the PVA concentration and chain length, the size of the obtained polymer gel particles was maintained in the nanometer range. Furthermore, we found that the clouding-point temperature increased when using low-molecular weight PVA. We believe that the knowledge gained in this study regarding the effect of PVA concentration and chain length on nanogel formation will aid in the future fabrication of functional polymer nanogels.

  • Cationic lipid potentiated the adjuvanticity of polysaccharide derivative-modified liposome vaccines.

    Antigen carriers that can selectively deliver antigens to antigen presenting cells and which can simultaneously activate these cells (adjuvant property) are necessary for efficient cancer immunotherapy or vaccination. Delivery of a model antigen into dendritic cell cytosol has been achieved by pH-responsive polymer-modified liposomes via destabilization of endosomal membranes responding to acidic pH, which impelled antigen-specific cellular immunity. Furthermore, β-glucan-based pH-responsive polysaccharides have shown not only cytosolic antigen delivery performance but also adjuvant property, which further heightened cellular immune responses. Because pH-responsive polysaccharides have anionic carboxy groups, cationic lipid was introduced to liposomes in this study to improve the modification efficiency of pH-responsive polysaccharides and to improve their adjuvanticity and immunity-inducing functions. Introduction of cationic lipids increased the amounts of polysaccharide derivatives on the liposome and increased the cellular association of the liposomes to dendritic cells. Liposomes containing β-glucan-based pH-responsive polysaccharides and cationic lipids increased cytokine production from dendritic cells much more than other polysaccharide derivatives did. Furthermore, through improvement of intra-tumoral immunosuppression and induction of antigen-specific cellular immunity, administering these liposomes impelled tumor suppression even with a small antigen dose. These results suggest that introducing cationic lipids and using pH-responsive polysaccharides having intrinsically adjuvant function are effective for producing liposomal nanovaccines showing strong immunity-inducing function.

    Induction of cellular immunity is important for effective cancer immunotherapy. Although various antigen carriers for cancer immunotherapy have been developed to date, balancing efficient antigen delivery to antigen presenting cells (APCs) and their activation via innate immune receptors, both of which are crucially important for the induction of strong cellular immunity, remains challenging. For this study, branched β-glucan was selected as an intrinsically immunity-stimulating and biocompatible material. It was engineered to develop multifunctional liposomal cancer vaccines capable of efficient interactions with APCs and subsequent activation of the cells. Hydroxy groups of branched β-glucan (Aquaβ) were modified with 3-methylglutaric acid ester and decyl groups, respectively, to provide pH-sensitivity and anchoring capability to the liposomal membrane. The modification efficiency of Aquaβ derivatives to the liposomes was significantly high compared with linear β-glucan (curdlan) derivatives. Aquaβ derivative-modified liposomes released their contents in response to weakly acidic pH. As a model antigenic protein, ovalbumin (OVA)-loaded liposomes modified with Aquaβ derivatives interacted efficiently with dendritic cells, and induced inflammatory cytokine secretion from the cells. Subcutaneous administration of Aquaβ derivative-modified liposomes suppressed the growth of the E.G7-OVA tumor significantly compared with curdlan derivative-modified liposomes. Aquaβ derivative-modified liposomes induced the increase of CD8+ T cells, and polarized macrophages to the antitumor M1-phenotype within the tumor microenvironment. Therefore, pH-sensitive Aquaβ derivatives can be promising materials for liposomal antigen delivery systems to induce antitumor immune responses efficiently.

    Poor distribution of nanocarriers at the tumor site and insufficient drug penetration into the tissue are major challenges in the development of effective and safe cancer therapy. Here, we aim to enhance the therapeutic effect of liposomes by accumulating doxorubicin-loaded liposomes at high concentrations in and around the tumor, followed by heat-triggered drug release to facilitate low-molecular-weight drug penetration throughout the tumor. A cyclic RGD peptide (cRGD) was incorporated into liposomes decorated with a thermosensitive polymer that allowed precise tuning of drug release temperature (i.e., Polymer-lip) to develop a targeted thermosensitive liposome (cRGD-Polymer-lip). Compared with conventional thermosensitive liposomes, cRGD-Polymer-lip enhanced the binding of liposomes to endothelial cells, leading to their accumulation at the tumor site upon intravenous administration in tumor-bearing mice. Drug release triggered by local heating strongly inhibited tumor growth. Notably, tumor remission was achieved via multiple administrations of cRGD-Polymer-lip and heat treatments. Thus, combining the advantages of tumor neovascular targeting and heat-triggered drug release, these liposomes offer high potential for minimally invasive and effective cancer chemotherapy.

    RNA interference (RNAi) using siRNA has gained much attention for use in therapies for cancer and genetic disorders. To establish RNAi-based therapeutics, the development of efficient siRNA nanocarriers is desired. Earlier, we developed polyamidoamine dendron-bearing lipids able to form complexes with nucleic acids as gene vectors. Especially, dendron lipids with unsaturated alkyl chains (DL-G1-U2) induced efficient endosomal escape by membrane fusion, leading to efficient transfection in vitro. For this study, dendron lipids having oleyl/linoleyl groups (DL-G1-U3) were designed to increase membrane fusogenic activity further. Indeed, DL-G1-U3/siRNA complexes achieved higher membrane fusogenic activity and knockdown of the target gene more efficiently than conventional DL-G1-U2/siRNA complexes did. A hydrophilic polymer, hyperbranched polyglycidol lauryl ester (HPG-Lau), was modified further on the surface of DL-G1-U3/siRNA complexes to provide colloidal stability. Surface modification of HPG-Lau increased the colloidal stability in a physiological condition more than complexes without HPG-Lau. Importantly, HPG-Lau-coated DL/siRNA complexes showed identical RNAi effects to those of parental DL/siRNA complexes, whereas the RNAi activity of poly(ethylene glycol)-bearing lipid (PEG-PE)-modified DL/siRNA complexes was hindered completely. Introduction of unsaturated bonds into dendron lipids and selection of suitable hydrophilic polymers for nanocarrier modification are important for obtaining efficient siRNA vectors toward in vivo siRNA delivery.

    Specific delivery to antigen presenting cells (APC) and precise control of the intracellular fate of antigens are crucial to induce cellular immunity that directly and specifically attacks cancer cells. We previously achieved cytoplasmic delivery of antigen and activation of APC using carboxylated curdlan-modified liposomes, which led to the induction of cellular immunity in vivo. APCs express mannose receptors on their surface to recognize pathogen specifically and promote cross-presentation of antigen. In this study, mannose-residue was additionally introduced to carboxylated curdlan as a targeting moiety to APC for further improvement of polysaccharide-based antigen carriers. Mannose-modified curdlan derivatives were synthesized by the condensation between amino group-introduced mannose and carboxy group in pH-sensitive curdlan. Mannose residue-introduced carboxylated curdlan-modified liposomes showed higher pH-sensitivity than that of liposomes modified with conventional carboxylated curdlan. The introduction of mannose-residue to the liposomes induced aggregation in the presence of Concanavalin A, indicating that mannose residues were presented onto liposome surface. Mannose residue-introduced carboxylated curdlan-modified liposomes exhibited high and selective cellular association to APC. Furthermore, mannose residue-introduced carboxylated curdlan-modified liposomes promoted cross-presentation of antigen and induced strong antitumor effects on tumor-bearing mice. Therefore, these liposomes are promising as APC-specific antigen delivery systems for the induction of antigen-specific cellular immunity.

    The combination of anticancer drugs and laser hyperthermia could lead to efficient cancer treatment with less-adverse effects. This study combined anticancer drug-loaded functional dendrimers and light-responsive gold nanorods to fabricate nanohybrids that can provide anticancer-drug delivery and subsequent heat generation under near-infrared laser irradiation. A condensation reaction was used to conjugate poly(ethylene glycol)-modified polyamidoamine dendrimers to carboxylated gold nanorod surfaces. Oleoyl groups were incorporated into dendrimers to improve the drug loading capacity. Doxorubicin loading capacity was improved by incorporation of oleoyl chains into dendrimers in the nanohybrid, indicating increased hydrophobic interaction between anticancer drugs and nanohybrids. The nanohybrids exhibited heat generation properties under near infrared laser irradiation. They released anticancer drugs over time. The combination of doxorubicin-loaded nanohybrids and laser irradiation showed markedly better cytotoxicity than that of the nanohybrids used with lasers and drug-loaded nanohybrids without the use of lasers. After intravenous or intratumoral injection of nanohybrids to tumor-bearing mice, a sharp temperature increase was observed at the tumor site under laser irradiation. Especially, intratumorally injected doxorubicin-loaded nanohybrids showed almost complete tumor growth suppression under laser irradiation. The results demonstrate that functional dendrimer-gold nanorod nanohybrids are promising as multi-functional nanomaterials to achieve synergistic effects of anticancer drugs and heat ablation to support effective cancer treatments.

    Temperature-responsive nanocarrier systems using external stimuli are one of the most widely investigated stimuli-responsive strategies because heat is easy and safe to use for hyperthermia and controlled drug delivery. Polyamidoamine dendron lipids (PAMAM-DLs) composed of PAMAM dendron as head group and two alkyl chains can exhibit temperature-responsive morphological change through the attachment of suitable moieties to terminal of PAMAM dendron. In this study, oligo(ethylene glycol)s including ethoxy- or methoxy-diethylene glycols were attached to the terminals of PAMAM-DL, and temperature-responsive properties of their self-assemblies were evaluated by calorimetric and turbidity measurements. In the evaluation of temperature-responsive properties, ethoxy diethylene glycol (EDEG)-attached PAMAM-DL composed of two saturated alkyl chains and PAMAM dendron with 1st generation had lipid bilayer structure and suitable cloud point for the application as drug carrier. In vitro performances of the assemblies combining EDEG-attached PAMAM-DLs with cholesteryl-oxy-poly(ethylene glycol) (PEG-Chol) was evaluated using doxorubicin (DOX) as an anticancer drug. Cellular uptake of DOX-loaded EDEG-attached PAMAM-DL/PEG-Chol assemblies was promoted at 42 °C rather than 37 °C, resulting in an effective decrease in cell viability.

    BACKGROUND: Gene delivery to target cells is crucially important to establish gene therapy and regenerative medicine. Although various virus-based and synthetic molecule-based gene vectors have been developed to date, selective transfection in a site or a cell level is still challenging. For this study, both light-responsive and temperature-responsive synthetic gene vectors were designed for spatiotemporal control of a transfection system. METHODS: 11-Mercaptoundecanoic acid-coated gold nanorods were mixed with polyamidoamine dendron-bearing lipids of two types having amino-terminus or ethoxydiethylene glycol-terminus to obtain hybrid vectors. Hybrid vectors were mixed further with pDNA. Then we investigated their physicochemical properties and transfection efficacy with or without near infrared laser irradiation. RESULTS: Hybrid vectors formed complexes with pDNA and exhibited enhanced photothermal property under near infrared laser irradiation compared with parent gold nanorods. Transfection efficacy of complexes was promoted considerably by brief laser irradiation soon after complex application to the cells. Analysis of intracellular distribution revealed that laser irradiation promoted the adsorption of complexes to the cells and cytosolic release of pDNA, which is derived from the change in surface hydrophobicity of complexes through dehydration of temperature-responsive groups. CONCLUSIONS: Hybrid vector is promising as a light-activatable transfection system.

    Poly(L-lysine)-bearing multi-arm poly(ethylene glycol) terminary (maPEG-PLL) can form nanorod and nanofiber polyplexes with plasmid DNA (pDNA) depending on the size (exclusion volume) of maPEG. Nanorod and nanofiber polyplexes were prepared using maPEG-PLL bearing different maPEG sizes. Gene expression of nanofiber and nanorod polyplexes was comparable, although the cellular uptake of nanofiber polyplexes was less than that of nanorod polyplexes. This suggests that there is a difference in cellular activities after polyplex enters the cell. The release of pDNA from polyplexes through the exchange with heparin occurred more easily in nanorod polyplexes than it did in nanofiber polyplexes. However, it was confirmed by real-time PCR measurements that pDNA molecules in nanofiber polyplexes exhibit high reactivity with polymerase compared with that in nanorod polyplexes. Further, higher reactivity of pDNA with polymerase in nanofiber polyplexes was maintained even in the presence of crowding cosolutes including Ficoll and dextran. This suggests that pDNA in nanofiber polyplex might reflect a higher efficiency of transcription process in the cell compared with pDNA in nanorod polyplex. These results provide valuable information in the design of nonviral gene vectors using cationic polymers.

    Cancer immunotherapy has gained much attention because of the recent success of immune checkpoint inhibitors. Nevertheless, clinical therapeutic effects of immune checkpoint inhibitors remain limited, probably because most patients have other immune checkpoint molecules or because they lack cancer-specific cytotoxic T lymphocytes. Induction of cancer-specific cytotoxic T lymphocytes requires efficient antigen delivery systems that can convey cancer antigens specifically to antigen presenting cells, promote the endosomal escape of antigen into cytosol, and activate immune cells. Earlier, we reported cytoplasmic delivery systems of antigen using pH-sensitive polymer-modified liposomes. Adjuvant molecules were further incorporated into these liposomes to provide activation properties of cellular immune responses. This study further introduced cell specificity to these liposomal systems using hyaluronic acid-based pH-sensitive polymers, which are recognized by CD44 expressing on antigen presenting cells. pH-Sensitive hyaluronic acid derivative-modified liposomes showed much higher cellular association to antigen presenting cells than to fibroblasts with less CD44 expression. These liposomes achieved the delivery of model antigenic proteins into cytosol of dendritic cells and promoted Th1 cytokine production from the cells. Subcutaneous administration of these liposomes to mice induced antigen-specific cellular immune response in the spleen, leading to tumor regression in tumor-bearing mice. The results show that pH-sensitive hyaluronic acid derivative-modified liposomes are promising as multifunctional antigen carriers having cell-specificity, cytoplasmic antigen delivery performance, and adjuvant property to induce antigen-specific cellular immunity.

    Controlling the aspect ratio of polyplexes prepared by mixing pDNA with a polycation mixture of a poly(l-lysine) (PLL) homopolymer and PLL terminally bearing a multiarm poly(ethylene glycol) (PEG) part (maPEG-PLL) was examined. By varying the maPEG-PLL content in the polycation mixture, the condensation of pDNA accompanied by polyplex formation and the morphology of the polyplexes were evaluated by a dye exclusion assay and AFM observations, respectively. Increasing the maPEG-PLL content caused elongation of the polyplex, and polyplexes with aspect ratios from 2 to 10 were prepared successfully by controlling the maPEG-PLL content. The reactivity of pDNA in the polyplexes with varying aspect ratios against DNase I and polymerase were examined by agarose gel electrophoresis and real-time PCR measurements, respectively. Moreover, cellular uptake and transfection efficiency of the polyplexes by HeLa cells was evaluated. The results revealed that an increase in aspect ratio of the polyplexes caused an increase in PCR efficiency with a concomitant decrease in cellular uptake.

    Induction of cancer-specific cytotoxic T lymphocytes is crucially important to complement therapeutic effects of immune checkpoint inhibitors and to achieve efficient cancer immunotherapy. To induce cancer-specific cytotoxic T lymphocytes, cancer antigen carriers must have multiple functions to deliver cancer antigens to antigen presenting cells, release antigens into cytosol, and promote the maturation of these cells. We earlier achieved cytosolic delivery of antigens and induction of antigen-specific cytotoxic T lymphocytes using carboxylated polyglycidol or polysaccharide derivative-modified liposomes that can induce membrane fusion with endosomes in response to weakly acidic pH. Furthermore, pH-sensitivity and adjuvant properties of these polymers were enhanced strongly by introduction of hydrophobic carboxylated units to dextran. Against our expectations, these polymer-modified liposomes only slightly induce cancer immunity, probably because of the high hydrophobicity of spacer units. This study used a polysaccharide with charged groups (chondroitin sulfate) instead of dextran as a backbone to reduce hydrophobicity. Chondroitin sulfate derivative-modified liposomes showed almost equal pH-sensitivity to that of dextran derivative-modified liposomes and achieved selective delivery to dendritic cells, whereas dextran derivative-modified liposomes were highly taken up by both dendritic cells and fibroblasts. Chondroitin sulfate derivative-modified liposomes delivered model antigenic proteins into cytosol of dendritic cells and promoted cytokine production from the cells, leading to tumor regression on tumor-bearing mice after subcutaneous administration. Results demonstrate that charged groups having polysaccharide as a backbone can be used in an effective strategy to balance strong hydrophobicity of spacer units with their utilization for immunity-inducing systems.
