As a potential method for tumor treatment, tumor vaccine immunization induces a tumor-specific cellular immune response via immunization with tumor antigens. The delivery of exogenous antigen proteins into the cytoplasm of antigen-presenting cells is well known to induce an intensive cellular immune response for tumor treatment. In this work, we fluorinated a redox-responsive hyperbranched poly(amidoamine) (HPAA) with heptafluorobutyric anhydride to prepare a fluorinated HPAA (HPAA-F7) for use as a vaccine delivery system for antitumor therapy. The immunization results show that HPAA-F7 as a vaccine carrier could effectively promote the intracellular uptake and cytoplasmatic delivery of antigen proteins and induce potent antitumor cellular immunity. The novel vaccine carrier HPAA-F7 could be further developed for antitumor immunotherapy.

Galectin-3 (gal-3) plays a crucial role in various cellular events associated to tumor metastasis and progression. In this direction, gal-3 binding core-shell glyconanoparticles based on citrus pectin (CP) have been designed for targeted, trigger-responsive combination drug delivery. Depolymerization via periodate oxidation in heterogeneous medium yielded low-molecular weight dialdehyde oligomers (CPDA) of CP with a gal-3 binding property (K-d = 160.90 mu M). CPDA-based core-shell nanoparticles prepared to enhance the gal-3 binding specificity via a multivalent ligand presentation have shown to reduce homotypic cellular aggregation, tumor cell binding with endothelial cells, and endothelial tube formation, the major steps involved in the progression of cancer. Immune-fluorescence and flow cytometric analysis confirmed significant reduction in gal-3 expression on MDA-MB 231 cancer cells upon incubation with nanoparticles. An on-demand tumor microenvironment-responsive release of drugs at low pH and high concentrations of glucose and glutathione prevailing in tumor milieu was achieved by introducing a cleavable Schiff’s base, a boronate ester, and disulfide linkages within the shell of the nanoparticles. Nanoparticles with encapsulated sulindac in the core and doxorubicin (DOX) in the shell demonstrated target specificity and enhanced internalization with synergistic cytotoxic effects with a 30-fold reduction in IC50 in DOX-resistant, triple-negative MDA-MB 231 breast cancer cells. Nanoparticles were radiolabeled with 131I radioisotopes with >= 80% efficiency while retaining its gal-3 binding property. Biodistribution studies of radiolabeled placebo nanoparticles and drug-loaded CPDA nanoparticles demonstrated proof of concept of gal-3 targeting seen as preferential accumulation in the gal-3-expressing tissues of the gastric tract. The CPDA core-shell nanoparticles are thus promising platforms for gal-3 targeting and inhibition of gal-3-mediated processes involved in cancer progression with a potential of radiolabeling for in vivo monitoring or delivering therapeutic doses of radiation and on-demand triggered, target-specific drug release.

To mimic the helical structure and function of biopolymers, shell cross-linked nanoparticle (P4) composed of left-handed helical poly(phenylborate isocyanide) in core and hydrophilic polyisocyanide in shell was prepared. The phenylborate in the core and the disulfide bonds in the cross-linkage render the nanoparticle with excellent dual stimuli-responsiveness to glutathione (GSH) and H2O2. Nevertheless, it has good stability in normal physiological conditions. Because of the helicity and borate pendants of the core, such nanoparticle has high capacity for anticancer drug loading, for example, the loading capacity of doxorubicin (DOX) was up to 68%. Moreover, the DOX-loaded DOX@P4 showed excellent tumor cell penetration potency and fast drug release. More than 78% of murine breast cancer cell (4T1) can be killed within 48 h, supporting this material with great potential in antitumor drug nanocarriers.

In this paper, a novel redox-responsive nanoparticles has been designed for targeted delivery of docetaxel (DTX). Chondroitin sulfate (CS) was used to construct the nanoparticles due to the ability of tumor targeting through binding with CD44 receptor that overexpresses on the surfaces of various tumor cells. A redox-responsive small-molecular DTX prodrug was prepared through modifying with cystamine containing disulfide bonds (Cys-DTX). Then the DTX prodrug was grafted to the CS to construct the amphiphilic polymer (CS-ss-DTX). Further, Cys-DTX/CS-ss-DTX nanoparticles were formed by self-assembly of amphiphilic polymer and incorporation of free Cys-DTX prodrug. This category of nanosized DTX delivery system was expected for not only exhibiting high permeability and cytotoxicity of Cys-DTX prodrug, but also targeting transportation of encapsulated redox-responsive Cys-DTX prodrug. According to results of related researches on physicochemical properties and biological evaluation, the novel redox-responsive Cys-DTX/CS-ss-DTX nanoparticles increased amount of DTX released from the nanoparticles in reductive environment, improved permeability in tumor tissues, enhanced cytotoxicity and decreased side effects compared with free DTX. All of these results showed that this kind of Cys-DTX/CS-ss-DTX nanoparticles were worthy of being expectation in tumor chemotherapy in future.

Real-time monitor of drug-release from drug formulations in a noninvasive way can provide spatio-temporal information for drug activation and guide further clinical rational administration. In this work, a molecular shuttle, as a typical nanosized artificial molecular machine, was managed to act as a conceptually-new nanotheranostics for oxaliplatin. A post-recognition strategy was utilized, where a default supramolecular-dye couple was pre-blocked. The rational design, synthesis, characterization and proof-of-concept of this strategy were described in detail. The drug-release upon reducing environment can be translated into near-infrared (NIR) fluorescence signal (OFF-to-ON), allowing to track the drug-release procedure by multi-modal images including IVIS, FLECT and photoacoustic imaging. The versatile nanotheranostics system can target to triple negative breast tumor via conjugated F3 peptide, and show an improved anti-tumor efficacy with much lower side effect. The intelligent nanotheranostics system based on molecular shuttle provides new reference for precision medicine in preclinical trial and postclinical evaluation.

In this study, reduction-sensitive self-assembled polymer nanoparticles based on poly (lactic-co-glycolic acid) (PLGA) and chondroitin sulfate A (CSA) were developed and characterized. PLGA was conjugated with CSA via a disulfide linkage (PLGA-ss-CSA). The critical micelle concentration (CMC) of PLGA-ss-CSA conjugate is 3.5 mu g/mL. The anticancer drug doxorubicin (DOX) was chosen as a model drug, and was effectively encapsulated into the nanoparticles (PLGA-ss-CSA/DOX) with high loading efficiency of 15.1%. The cumulative release of DOX from reduction-sensitive nanoparticles was only 34.8% over 96h in phosphate buffered saline (PBS, pH 7.4). However, in the presence of 20mM glutathione-containing PBS environment, DOX release was notably accelerated and almost complete from the reduction-sensitive nanoparticles up to 96h. Moreover, efficient intracellular DOX release of PLGA-ss-CSA/DOX nanoparticles was confirmed by CLSM assay in A549 cells. In vitro cytotoxicity study showed that the half inhibitory concentrations of PLGA-ss-CSA/DOX nanoparticles and free DOX against A549 cells were 1.141 and 1.825 mu g/mL, respectively. Therefore, PLGA-ss-CSA/DOX nanoparticles enhanced the cytotoxicity of DOX in vitro. These results suggested that PLGA-ss-CSA nanoparticles could be a promising carrier for drug delivery.

Injectable hydrogels have been widely applied in the field of regenerative medicine. However, current techniques for injectable hydrogels are facing a challenge when trying to generate a biomimetic, porous architecture that is well-acknowledged to facilitate cell behaviors. In this study, an injectable, interconnected, porous hyaluronic acid (HA) hydrogel based on an in-situ bubble self-generation and entrapment process was developed. Through an amide reaction between HA and cystamine dihydrochloride activated by EDC/NHS, CO2 bubbles were generated and were subsequently entrapped inside the substrate due to a rapid gelation-induced retention effect. HA hydrogels with different molecular weights and concentrations were prepared and the effects of the hydrogel precursor solution’s concentration and viscosity on the properties of hydrogels were investigated. The results showed that HA10-10 (10 wt.%, MW 100,000 Da) and HA20-2.5 (2.5 wt.%, MW 200,000 Da) exhibited desirable gelation and obvious porous structure. Moreover, HA10-10 represented a high elastic modulus (32 kPa). According to the further in vitro and in vivo studies, all the hydrogels prepared in this study show favorable biocompatibility for desirable cell behaviors and mild host response. Overall, such an in-situ hydrogel with a self-forming bubble and entrapment strategy is believed to provide a robust and versatile platform to engineer injectable hydrogels for a variety of applications in tissue engineering, regenerative medicine, and personalized therapeutics.

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.
