Personalized cancer vaccines from bacteria-derived outer membrane vesicles with antibody-mediated persistent uptake by dendritic cells. FUNDAMENTAL RESEARCH 2022; 2:23-36. [PMID: 38933907 PMCID: PMC11197747 DOI: 10.1016/j.fmre.2021.11.032] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/01/2021] [Revised: 11/15/2021] [Accepted: 11/30/2021] [Indexed: 10/19/2022] Open
Abstract
Nanocarriers with intrinsic immune adjuvant properties can activate the innate immune system while delivering tumor antigen, thus efficiently facilitating antitumor adaptive immunity. Bacteria-derived outer membrane vesicles (OMVs) are an excellent candidate due to their abundance of pathogen associated molecular patterns. However, during the uptake of OMVs by dendritic cells (DCs), the interaction between lipopolysaccharide and toll-like receptor 4 induces rapid DC maturation and uptake blockage, a phenomenon we refer to as "maturation-induced uptake obstruction" (MUO). Herein we decorated OMV with the DC-targeting αDEC205 antibody (OMV-DEC), which endowed the nanovaccine with an uptake mechanism termed as "not restricted to maturation via antibody modifying" (Normandy), thereby overcoming the MUO phenomenon. We also proved the applicability of this nanovaccine in identifying the human tumor neoantigens through rapid antigen display. In summary, this engineered OMV represents a powerful nanocarrier for personalized cancer vaccines, and this antibody modification strategy provides a reference to remodel the DC uptake pattern in nanocarrier design.

A Novel Hybrid Drug Delivery System for Treatment of Aortic Aneurysms. Int J Mol Sci 2020; 21:ijms21155538.

Abstract
Ongoing aortic wall degeneration and subsequent aneurysm exclusion failure are major concerns after an endovascular aneurysm repair with a stent-graft. An ideal solution would be a drug therapy that targets the aortic wall and inhibits wall degeneration. Here, we described a novel drug delivery system, which allowed repetitively charging a graft with therapeutic drugs and releasing them to the aortic wall in vivo. The system was composed of a targeted graft, which was labeled with a small target molecule, and the target-recognizing nanocarrier, which contained suitable drugs. We developed the targeted graft by decorating a biotinylated polyester graft with neutravidin. We created the target-recognizing nanocarrier by conjugating drug-containing liposomes with biotinylated bio-nanocapsules. We successfully demonstrated that the target-recognizing nanocarriers could bind to the targeted graft, both in vitro and in blood vessels of live mice. Moreover, the drug released from our drug delivery system reduced the expression of matrix metalloproteinase-9 in mouse aortas. Thus, this hybrid system represents a first step toward an adjuvant therapy that might improve the long-term outcome of endovascular aneurysm repair.

Abstract
A universal method to measure the binding affinities of antibody drugs towards their targets on the surface of living cells was developed based on atomic force microscopy (AFM) analysis. Nivolumab, an antibody drug targeting programmed cell death 1 (PD-1), was mainly used as a model for this evaluation. The surface of a tip-less AFM cantilever was coated with nano-capsules, on which immunoglobulin G-binding ZZ domains of protein A were exposed, and nivolumab molecules were immobilized on the cantilever through binding between the antibody Fc domains and the ZZ domains, which controlled the molecular orientation of the antibodies. Model human T lymphocytes (Jurkat), on which PD-1 molecules were highly expressed, were immobilized on a glass substrate via a lipid bilayer-anchoring reagent. The nivolumab-coated AFM cantilever was moved to approach the T cells, and the rupture forces between nivolumab molecules on the AFM cantilever and PD-1 molecules on the cell surface were measured. The average values of the rupture forces were 0.18 ± 0.10, 0.21 ± 0.18, 0.12 ± 0.07, 0.11 ± 0.06, and 0.12 ± 0.06 nN μm-2 at loading forces of 10, 20, 30, 40, and 50 nN, respectively. Application of significantly higher loading forces decreased the S/N ratio, as confirmed by comparison with control T cells with low PD-1 expression, which suggested that a low loading force of less than 20 nN was sufficient for these measurements. A correlation between the expression levels of PD-1 and the rupture force values was confirmed using immunofluorescence. A similar assay was performed by using an antibody drug targeting epidermal growth factor receptor (EGFR) and a model cancer cell expressing EGFR molecules (A431) to evaluate the universal application of the developed method for various antibody drugs, and the same conclusions as that in nivolumab's case were obtained. This method can be applied to living cells without any chemical treatment, which allows the present method to compare the affinities of various antibody drugs towards the same single cell. These results indicated that the present method is useful for selecting the most effective candidates from various antibody drugs from the point of view of binding forces between antibodies and living cells.

Abstract
The orientation and density of biosensing molecules on sensor chip should be precisely controlled to improve sensitivity and ligand-binding capacity. We previously developed a ~30-nm bio-nanocapsule (ZZ-BNC), consisting of the hepatitis B virus envelope L protein fused with the tandem form of protein A-derived IgG Fc-binding Z domain (ZZ-L protein). This is used as a robust nanoparticle scaffold to enhance the sensitivity and ligand-binding capacity of IgGs and Fc-fused sensing molecules (Fc-fused receptors). However, due to their rigid particle structure, the surface density of ZZ-L proteins could not be optimized for biosensor functions, and useless ZZ-L proteins become stuck between ZZ-BNC and the sensor chip. Here, we have developed a planar lipid membrane embedded with ZZ-L micelles (ZZ-L membrane), which could modify the surface of any biosensor chip with a controlled density of ZZ-L proteins. Compared with ZZ-BNC, the sensitivity and ligand-binding capacity of IgGs were enhanced about 10-fold with the ZZ-L membrane. Furthermore, the immobilized IgGs could capture their respective antigens almost stoichiometrically, indicating that ZZ-L membrane is the most ideal scaffold for Fc-fused sensing molecules in terms of both clustering and oriented immobilization.

Abstract
Antibody drugs have been important therapeutic agents for treating various diseases, such as cancer, rheumatism, and hypercholesterolemia, for the last three decades. Despite showing excellent therapeutic efficacy with good safety in vivo, they require high doses. We have developed a ∼30-nm bio-nanocapsule (ZZ-BNC) consisting of hepatitis B virus envelope L protein fused with the tandem form of protein A-derived IgG Fc-binding Z domain (ZZ-L protein), for tethering antibodies in an oriented immobilization manner. In this study, antibody drugs were spontaneously conjugated to ZZ-BNC, which displayed the IgG Fv regions outwardly. The anti-human epidermal growth factor receptor IgG conjugated to ZZ-BNC (α-hEGFR-ZZ-BNC) was endocytosed by the human epidermoid carcinoma A431 cells, with increases in cellular uptake by ∼1.5 fold, compared that of α-hEGFR IgG alone. The amount of α-hEGFR IgG in the late endosomes and lysosomes was increased from 4% to 33% by the conjugation to ZZ-BNC. The in vitro cytotoxicity of α-hEGFR-ZZ-BNC was higher by ∼10-fold than that of α-hEGFR IgG alone. Furthermore, in vivo tumor growth was significantly reduced by α-hEGFR-ZZ-BNC than by α-hEGFR IgG alone. Taken together, since endosomal EGFR, not cell surface EGFR, played a pivotal role in the EGFR-mediated signaling cascade, ZZ-BNC increased α-hEGFR IgG avidity by efficiently repressing the activation of hEGFR not only on the cell surface, but presumably also in the endosomes. These results strongly suggested that ZZ-BNC is a promising nano-scaffold for enhancing the therapeutic efficacy and reducing the dose of antibody drugs. STATEMENT OF SIGNIFICANCE: Antibody drugs are widely used for treating severe diseases, such as cancer, rheumatism, and hypercholesterolemia. These drugs are composed of naturally occurring biomaterials with low immunogenicity and toxicity, as well as long in vivo serum half-life. To achieve sufficient therapeutic efficacy, the dose of antibody drugs are unavoidably higher than those of conventional drugs. The present study shows an innovative way to reduce the dose of antibody drugs by using a nanocarrier-conjugated antibody. Oriented immobilization of the antibody enhanced its avidity, endocytosis efficiency, and therapeutic efficacy.

Abstract
BACKGROUND Various nanocarriers have been used to deliver subunit vaccines specifically to dendritic cells (DCs) for the improvement of immunogenicity. However, due to their insufficient DC priming ability, these vaccines could not elicit effective innate immunity. We have recently developed a DC-targeting bio-nanocapsule (BNC) by displaying anti-CD11c IgGs via protein A-derived IgG Fc-binding Z domain on the hepatitis B virus envelope L protein particles (α-DC-ZZ-BNC). RESULTS After the chemical modification with antigens (Ags), the α-DC-ZZ-BNC-Ag complex could deliver Ags to DCs efficiently, leading to effective DC maturation and efficient endosomal escape of Ags, followed by Ag-specific T cell responses and IgG productions. Moreover, the α-DC-ZZ-BNC modified with Japanese encephalitis virus (JEV) envelope-derived D3 Ags could confer protection against 50-fold lethal dose of JEV injection on mice. CONCLUSION The α-DC-ZZ-BNC-Ag platform was shown to induce humoral and cellular immunities effectively without any adjuvant.

Abstract
Molecular detection of target molecules with high sensitivity and specificity is of great significance in bio and medical sciences. Here, we present genetically functionalized ferritin nanoparticles with a high-affinity protein binder, and their utility as a signal generator in a variety of immunoassays and imaging. As a high-affinity protein binder, human IgG-specific repebody, which is composed of LRR (Leucine-rich repeat) modules, was used. The repebody was genetically fused to the N-terminal heavy-chain ferritin, and the resulting subunits were self-assembled to the repebody-ferritin nanoparticles composed of 24 subunits. The repebody-ferritin nanoparticles were shown to have a three-order of magnitude higher binding affinity toward human IgG than free repebody mainly owing to a decreased dissociation rate constant. The repebody-ferritin nanoparticles were conjugated with fluorescent dyes, and the resulting nanoparticles were used for western blotting, cell imaging, and flow cytometric analysis. The dye-labeled repebody-ferritin nanoparticles were shown to generate about 3-fold stronger fluorescent signals in immunoassays than monovalent repebody. The repebody-functionalized ferritin nanoparticles can be effectively used for sensitive and specific immunoassays and imaging in many areas.

Abstract
Nanomaterial based imaging approaches hold substantial promise in addressing current diagnostic and therapeutic challenges. One of the key requirements for the successful clinical translation of nanomaterials is their complete clearance from the body within a reasonable time period preferably via the renal filtration route. This article describes the synthesis of highly fluorescent, water soluble, resorcinarene cavitand nanocapsules and demonstrates their effective renal clearance in mice. The synthesis and functionalization of nanocapsules was accomplished in a one-pot operation via thiol-ene reactions without involving self-assembly, sacrificial templates or emulsions. Water soluble resorcinarene cavitand nanocapsules obtained by this approach were covalently functionalized with Alexa Fluor 750. Highly fluorescent nanocapsules with hydrodynamic diameters of 122 nm and 68 nm and extinction coefficients of 1.3 × 10(9) M(-1) cm(-1) and 1.5 × 10(8) M(-1) cm(-1) respectively were prepared by varying the reaction conditions. The in vivo biodistribution and clearance of these nanocapsules in mice followed by whole-body fluorescence imaging showed that they were both cleared renally within a few hours. Given the inherent encapsulation capabilities of nanocapsules, the renal clearance demonstrated in this work opens up new opportunities for their theranostic applications especially for targeting and treating the urinary tract.

Abstract
The bio-nanocapsule (BNC) is an approximately 30-nm particle comprising the hepatitis B virus (HBV) envelope L protein and a lipid bilayer. The L protein harbors the HBV-derived infection machinery; therefore, BNC can encapsulate payloads such as drugs, nucleic acids, and proteins and deliver them into human hepatocytes specifically in vitro and in vivo. To diversify the possible functions of BNC, we generated ZZ-BNC by replacing the domain indispensable for the human hepatotrophic property of BNC (N-terminal region of L protein) with the tandem form of the IgG Fc-binding Z domain of Staphylococcus aureus protein A. Thus, the ZZ-BNC is an active targeting-based drug delivery system (DDS) nanocarrier that depends on the specificity of the IgGs displayed. However, the Z domain limits the animal species and subtypes of IgGs that can be displayed on ZZ-BNC. In this study, we introduced into BNC an Ig κ light chain-binding B1 domain of Finegoldia magna protein L (protein-L B1 domain) and an Ig Fc-binding C2 domain of Streptococcus species protein G (protein-G C2 domain) to produce LG-BNC. The LL-BNC was constructed in a similar way using a tandem form of the protein-L B1 domain. Both LG-BNC and LL-BNC could display rat IgGs, mouse IgG1, human IgG3, and human IgM, all of which not binding to ZZ-BNC, and accumulate in target cells in an antibody specificity-dependent manner. Thus, these BNCs could display a broad spectrum of Igs, significantly improving the prospects for BNCs as active targeting-based DDS nanocarriers. STATEMENT OF SIGNIFICANCE We previously reported that ZZ-BNC, bio-nanocapsule deploying the IgG-binding Z domain of protein A, could display cell-specific antibody in an oriented immobilization manner, and act as an active targeting-based DDS nanocarrier. Since the Z domain can only bind to limited types of Igs, we generated BNCs deploying other Ig-binding domains: LL-BNC harboring the tandem form of Ig-binding domain of protein L, and LG-BNC harboring the Ig binding domains of protein L and protein G sequentially. Both BNCs could display a broader spectrum of Igs than does the ZZ-BNC. When these BNCs displayed anti-CD11c IgG or anti-EGFR IgG, both of which cannot bind to Z domain, they could bind to and then enter their respective target cells.

Abstract
Tools such as protein immunoblotting have proven benefits for investigating T lymphocyte signaling but have several drawbacks such as the number of cells required and the difficulty of distinguishing subset-specific differences without expensive and invasive cell sorting. Recent advances in immunology and the identification of T lymphocyte sub-populations making up only a very small fraction of the total population highlight the importance of studying signaling in those small subsets in a feasible, cost-effective, high-throughput manner. To this end, we have developed a simplified protocol to study both intracellular phosphorylation patterns of important signal transduction molecules concomitantly with T cell surface marker expression. A multi-parametric analysis may allow the quantification of the phosphorylation of up to five signaling molecules in CD4 and CD8 T lymphocytes and their naïve, central memory, effector memory, and TEMRA subsets. This enables precise identification of subset-specific signaling and alterations of signaling pathways in physiological and pathological situations. The importance of such detailed analysis is discussed.

Abstract
Oriented immobilization of sensing molecules on solid phases is an important issue in biosensing. In case of immunosensors, it is essential to scrutinize not only the direction and shape of immunoglobulin G (IgG) in solution but also the real-time movement of IgGs, which cannot be achieved by conventional techniques. Recently, we developed bio-nanocapsules (BNCs) displaying a tandem form of the IgG Fc-binding Z domain derived from Staphylococcus aureus protein A (ZZ-BNC) to enhance the sensitivity and antigen-binding capacity of IgG via oriented-immobilization. Here, we used high-speed atomic force microscopy (HS-AFM) to reveal the fine surface structure of ZZ-BNC and observe the movement of mouse IgG3 molecules tethered onto ZZ-BNC in solution. ZZ-BNC was shown to act as a scaffold for oriented immobilization of IgG, enabling its Fv regions to undergo rotational Brownian motion. Thus, HS-AFM could decipher real-time movement of sensing molecules on biosensors at the single molecule level.

Abstract
Dendritic cells (DCs) are key regulators of adaptive T-cell responses. By capturing exogenous antigens and presenting antigen-derived peptides via major histocompatibility complex molecules to naïve T cells, DCs induce antigen-specific immune responses in vivo. In order to induce effective host immune responses, active delivery of exogenous antigens to DCs is considered important for future vaccine development. We recently generated bionanocapsules (BNCs) consisting of hepatitis B virus surface antigens that mediate stringent in vivo cell targeting and efficient endosomal escape, and after the fusion with liposomes (LP) containing therapeutic materials, the BNC-LP complexes deliver them to human liver-derived tissues in vivo. BNCs were further modified to present the immunoglobulin G (IgG) Fc-interacting domain (Z domain) derived from Staphylococcus aureus protein A in tandem. When mixed with IgGs, modified BNCs (ZZ-BNCs) displayed the IgG Fv regions outwardly for efficient binding to antigens in an oriented-immobilization manner. Due to the affinity of the displayed IgGs, the IgG-ZZ-BNC complexes accumulated in specific cells and tissues in vitro and in vivo. After mixing ZZ-BNCs with antibodies against DCs, we used immunocytochemistry to examine which antibodies delivered ZZ-BNCs to mouse splenic DCs following intravenous injection of the ZZ-BNCs. ZZ-BNCs displaying anti-CD11c monoclonal antibodies (α-CD11c-ZZ-BNCs) were found to accumulate with approximately 62% of splenic DCs, and reside within some of them. After the fusion with liposomes containing antigens, the α-CD11c-ZZ-BNCs could elicit the respective antibodies more efficiently than other nontargeting control vaccines, suggesting that this DC-specific nanocarrier is promising for future vaccines.
