Recent advances in the development of protein-based vaccines have expanded the opportunities for preventing and treating both infectious diseases as well as cancer. However, the development of readily and efficient antigen delivery systems capable of stimulating strong cytotoxic T-lymphocyte (CTL) responses remains a challenge. With the attempt to closely mimic the properties of viruses in terms of their size and molecular organization, we constructed RNA (which is a ligand for Toll-like receptor 7 (TLR7) and TLR8) and antigen-loaded nanoparticles resembling the structural organization of viruses. Cationic polymers containing either azide or bicyclo[6.1.0]nonyne (BCN) groups were synthesized as electrostatic glue that binds negatively charged single stranded RNA (PolyU) to form a self-crosslinked polyplex core. An azide-modified model antigen (ovalbumin, OVA) and a BCN-modified mannosylated or galactosylated polymer were sequentially conjugated to the RNA core via disulfide bonds using copper free click chemistry to form the shell of the polyplexes. The generated reducible virus mimicking particles (VMPs) with a diameter of 200 nm and negatively surface charge (-14 mV) were colloidally stable in physiological conditions. The immunogenicity of these VMP vaccines was evaluated both in vitro and in vivo. The surface mannosylated VMPs (VMP-Man) showed 5 times higher cellular uptake by bone marrow derived DCs (BMDCs) compared to galactosylated VMP (VMP-Gal) counterpart. Moreover, VMP-Man efficiently activated DCs and greatly facilitated MHC I Ag presentation in vitro. Vaccination of mice with VMP-Man elicited strong OVA-specific CTL responses as well as humoral immune responses. These results demonstrate that the modular core-shell polymeric nanoparticles described in this paper are superior in inducing strong and durable immune responses compared to adjuvanted protein subunit vaccines and offer therefore a flexible platform for personalized vaccines.

Saw the article Combined pH-responsive chemotherapy and glutathione-triggered photosensitization to overcome drug-resistant hepatocellular carcinoma – a SPP/JPP Young Investigator Award paper published in 2020.0, Reprint Addresses Lo, PC (corresponding author), City Univ Hong Kong, Dept Biomed Sci, Kowloon, Tat Chee Ave, Hong Kong, Peoples R China..

Doxorubicin (DOX) resistance, which results in a reduced accumulation of DOX in the nucleus and hence decreased DNA damage, is a major challenge for chemotherapy against hepatocellular carcinoma. In this paper, we combined chemotherapy with photodynamic therapy (PDT) to combat DOX-resistant human hepatocellular carcinoma cells. We have prepared the polymeric micelles conjugating with DOX and zinc(II) phthalocyanine (ZnPc) through a pH-responsive hydrazone linker and a glutathione (GSH)-responsive disulfide linker, respectively. The polymeric micelles (DOX-ZnPc-micelles) exhibited a spherical shape with a size of about 98 mn diameter and showed excellent stability in aqueous solution. Due to the self-quenching of the ZnPc inside the micelles, DOX-ZnPc-micelles did not emit fluorescence upon red light irradiation. Drug release experiments verified that DOX and ZnPc could be released under acidic conditions and reducing environments, respectively. A higher concentration of DOX was internalized into DOX-resistant R-HepG2 cells through the delivery of polymeric micelles when compared with the free DOX, hence DOX-ZnPc-micelles exhibited a significant enhancement in anticancer activity. The IC50 value of DOX against R-HepG2 cells was found to be 21 mu M when combined with PDT and it was 5-fold less than that of a single treatment of DOX (102 mu M). The DOX-ZnPc-micelles could induce cell apoptosis and necrosis on R-HepG2 cells by combined therapeutic modalities, while these micelles induced only apoptosis on IiepG2 cells. We have demonstrated that utilization of polymeric micelles can significantly enhance the cellular uptake and cytotoxicity of DOX against R-HepG2 cells when compared with free DOX. Moreover, PDT can act as an adjuvant therapeutic modality and combine with chemotherapy to further improve therapeutic efficacy. Overall speaking, DOX-ZnPc-micelles can overcome DOX resistance and induce a synergistic therapeutic effect against DOX-resistant R-HepG2 cells, hence improving the therapeutic efficacy when compared with monotherapy.

Research on metal-free room-temperature phosphorescent (RTP) materials has been a hot topic and made great advances in recent years. However, developing amorphous metal-free RTP compounds whose RTP emission is insensitive to water and oxygen to expand their applications still remains a challenge. Two novel metal-free RTP compounds were facilely designed and synthesized by modifying ureidopyrinidinone (UPy) units on both ends of the phosphors (BrNpA and BrBA). On the basis of their water/oxygen insensitive phosphorescence at different emission wavelengths, pure white-light (CIE coordinates (0.32, 0.33)) emission was obtained by mixing these two compounds. Moreover, visualization of latent fingerprints employing RTP materials as the first application in forensic science, as well as protected quick response codes, was achieved by theses hydrophobic materials.

The combination of two imaging probes on the same biomolecule gives access to targeted bimodal imaging agents that can provide more accurate diagnosis, complementary information, or that may be used in different applications, such as nuclear imaging and fluorescence guided surgery. In this study, we demonstrate that dichlorotetrazine, a small, commercially available compound, can be used as a modular platform to easily assemble various imaging probes. Doubly labeled tetrazines can then be conjugated to a protein through a biorthogonal IEDDA reaction. A series of difunctionalized tetrazine compounds containing various chelating agents and fluorescent dyes was synthesized. As a proof of concept, one of these bimodal probes was conjugated to trastuzumab, previously modified with a constrained alkyne group, and the resulting dual-labeled antibody was evaluated in a mouse model, bearing a HER2-positive tumor. A significant uptake into tumor tissues was observed in vivo, by both SPECT-CT and fluorescence imaging, and confirmed ex vivo in biodistribution studies.

Polymer based core cross-linked nanoparticles (CCNPs) have generated a lot of interest as potential stimuli-responsive drug delivery systems. In the present work, we have synthesized smart redox-responsive water soluble polymeric CCNPs by cross-linking water-soluble PEG based copolymers with bis(acryloyl)cystamine via isoxazoline bond formation through a 1,3-dipolar cycloaddition reaction (click reaction) without using a copper catalyst, in a water-THF mixed solvent. The successful synthesis of CCNPs was confirmed by NMR, GPC and FT-IR measurements. Size distribution of the precursor copolymers and the CCNPs was determined by DLS measurement. AFM and FESEM images have confirmed globular morphology of these CCNPs. Their high stability in a physiological environment makes them effective as potent drug carriers with high loading capacity. MTT assays confirmed the biocompatibility of the synthesized CCNPs. Favourable cellular internalization of these DOX loaded CCNPs into cancer cells and redox-responsive release of DOX therefrom make these CCNP potentially smart vehicles to deliver anticancer drugs into cancer cells.

The utilization of nanotechnology to deliver vaccines and modulate immunity has shown great potential in cancer therapy. Peptide-based supramolecular hydrogels as novel vaccine adjuvants have been found to effectively improve the immune response and tumor curative effect. In this study, we designed a set of reduction-responsive self-assembled peptide precursors (Fbp-G(D)F(D)F(D)Y(D)(E, S, or K)-ss-ERGD), which can be reduced by glutathione (GSH) into Fbp-G(D)F(D)F(D)Y(D)(E, S or K)-SH for forming of hydrogel with different surface properties (E-gel, S-gel, and K-gel, respectively). Using the same method, co-assembled hydrogel vaccines (E-vac, S-vac, and K-vac, respectively) can also be prepared by mixing different precursors with antigens before GSH reduction. Through TEM observation of the nanostructure, we found that all the co-assembled hydrogels, especially K-vac, possessed much denser and more unified nanofiber networks as compared with antigen-free hydrogels, which were very suitable for antigen storage and vaccine delivery. Although the three peptides adopted similar beta-sheet secondary structures, the mechanical properties of their resulted co-assembled hydrogel vaccines were obviously different. Compared to E-vac, S-vac had a much weaker mechanical property, while K-vac had a much higher.In vivoexperiments, co-assembled hydrogel vaccines, especially K-vac, also promoted antibody production and anti-tumor immune responses more significantly than the other two vaccines. Our results demonstrated that co-assembled hydrogels formed by peptides and antigens co-assembly could act as effective vaccine delivery systems for boosting antibody production, and different immune effects can be acquired by tuning the surface properties of the involved self-assembling peptides.

This study aimed to develop an efficient step-by-step osteosarcoma (OS)-targeting liposome system functionalized with a redox-cleavable, bone- and cluster of differentiation 44 (CD44)-dual-targeting polymer. Furthermore, the effect of coadministration of a tumor-penetrating peptide, internalizing RGD (iRGD), was investigated. First, a bone-targeting moiety, alendronate (ALN), was conjugated with hyaluronic acid (HA), a ligand for CD44. This ALN-HA conjugate was coupled with DSPE PEG(2000)-COOH through a bioreducible disulfide linker (-SS-) to obtain a functionalized lipid, ALN-HA-SS-L, to be postinserted into preformed liposomes loaded with doxorubicin (DOX). The roles of ALN, HA, and the redox sensitivity of the ALN-HA-SS-L liposomes (ALN-HA-SS-L-L) in the anti-OS effect were critically evaluated against various reference liposomal formulations (with only ALN, HA, or redox sensitivity). ALN-HA-SS-L-L displayed a zeta potential of -26.07 +/- 0.32 mV and selectively disassembled in the presence of a reducing agent, 10 mM glutathione, which can be found in cancer cells. cells. Compared to various reference liposomes, ALN-HA-SS-L-L/DOX had significantly higher cytotoxicity to human OS MG-63 cells alongside high and rapid cellular uptake. In the orthotopic OS nude mouse models, ALN-HA-SS-L-L/DOX showed remarkable tumor growth suppression and prolonged survival time. This result was further improved by the coadministration of iRGD. The antitumor effects of various liposomes were ranked in the same order as the degree of tumor biodistribution shown by in vivo/ex vivo imaging: ALN-HA-SS-L-L coadministered with iRGD > ALN-HA-SS-L-L > HA-SS-L-L > HA-L-L > PEG-L> free drug. ALN-HA-SS-L-L/DOX also reduced the cardiotoxicity of DOX and lung metastases. Overall, this study demonstrated that ALN-HA-SS-L-L/DOX, equipped with bone- and CD44-dual-targeting abilities and redox sensitivity, could be a promising OS-targeted therapy. The efficacy could also be augmented by coadministration of iRGD.

For next-generation electronics, it is crucial to be able to accurately mimic the nature of human skin and develop skin-inspired materials and devices for electronic skin (e-skin) applications. However, it is a great challenge to design such a materials because they require the complex integration of stretchability, skin adhesiveness, transparency, healability, and tactile sensing. Herein, we present the first dual covalently reversible dynamic bond-based polymer that can be integrated with various functional materials and used as a skin-like sensor. A series of polymers was designed using polypropylene glycol (PPG)-based polyurethane (PU) as the polymer backbone, and these polymers could integrate two types of covalent reversible dynamic bonds, Diels-Alder and disulfide bonds, in one polymer for the first time. Based on our design, a polymer was created with the advantages of high stretchability, fast healing abilities (60 degrees C, 5 min), skin adhesion, recyclability, high transparency, and tactile sensing abilities. We provide an alternative strategy for the construction of skin-inspired multifunctional materials for e-skin applications.

Introducing clickable groups onto polymer microspheres allows the microspheres to be facilely functionalized via a click reaction. In this report, we have synthesized monodisperse PMMA microspheres with clickable double bonds on the surface by one-step RAFT-assisted dispersion photopolymerization using a cyclohexyl-containing macro-RAFT agent as a stabilizer. This macro-RAFT agent, named P(THPAA-b-AA)-TTC, was synthesized by RAFT-mediated block copolymerization of a cyclohexyl-containing monomer (THPAA, obtained by esterification of cis-1,2,3,6-tetrahydrophthalic with 2-hydroxyethyl acrylate) and acrylic acid. The obtained microspheres were analyzed by H-1 NMR and Iodometric method, indicating that the content of carbon double bonds on the microspheres increased with increasing the amount of P(THPAA-b-AA)-TTC in the polymerization feed. We then used a thiolated biotin to perform the photo-click reaction with the cyclohexene double bond on the micro spheres, thereby attaching the biotin unit onto the microspheres. The biotinylated PMMA microspheres were found to be able to effectively immobilize fluorescein isothiocyanate streptavidin (FITC-SAv) via the specific adsorption of biotin to streptavidin, and thus exhibited clear fluorescence under confocal microscope. This study provides a convenient and feasible way to prepare surface-functionalized microspheres, which has great potential in biological applications as well as other fields.
