Permeability of the Composite Magnetic Microcapsules Triggered by a Non-Heating Low-Frequency Magnetic Field. Pharmaceutics 2021; 14:65. [PMID: 35056960 PMCID: PMC8777611 DOI: 10.3390/pharmaceutics14010065] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/31/2021] [Revised: 12/17/2021] [Accepted: 12/20/2021] [Indexed: 11/25/2022] Open
Abstract
Nanosystems for targeted delivery and remote-controlled release of therapeutic agents has become a top priority in pharmaceutical science and drug development in recent decades. Application of a low frequency magnetic field (LFMF) as an external stimulus opens up opportunities to trigger release of the encapsulated bioactive substances with high locality and penetration ability without heating of biological tissue in vivo. Therefore, the development of novel microencapsulated drug formulations sensitive to LFMF is of paramount importance. Here, we report the result of LFMF-triggered release of the fluorescently labeled dextran from polyelectrolyte microcapsules modified with magnetic iron oxide nanoparticles. Polyelectrolyte microcapsules were obtained by a method of sequential deposition of oppositely charged poly(allylamine hydrochloride) (PAH) and poly(sodium 4-styrenesulfonate) (PSS) on the surface of colloidal vaterite particles. The synthesized single domain maghemite nanoparticles integrated into the polymer multilayers serve as magneto-mechanical actuators. We report the first systematic study of the effect of magnetic field with different frequencies on the permeability of the microcapsules. The in situ measurements of the optical density curves upon the 100 mT LFMF treatment were carried out for a range of frequencies from 30 to 150 Hz. Such fields do not cause any considerable heating of the magnetic nanoparticles but promote their rotating-oscillating mechanical motion that produces mechanical forces and deformations of the adjacent materials. We observed the changes in release of the encapsulated TRITC-dextran molecules from the PAH/PSS microcapsules upon application of the 50 Hz alternating magnetic field. The obtained results open new horizons for the design of polymer systems for triggered drug release without dangerous heating and overheating of tissues.

Abstract
Immunotherapy is moving to the frontier of cancer treatment. Drug delivery systems (DDSs) have greatly advanced the development of cancer immunotherapeutic regimen and combination treatment. DDSs can spatiotemporally present tumor antigens, drugs, immunostimulatory molecules, or adjuvants, thus enabling the modulation of immune cells including dendritic cells (DCs) or T-cells directly in vivo and thereby provoking robust antitumor immune responses. Cancer vaccines, immune checkpoint blockade, and adoptive cell transfer have shown promising therapeutic efficiency in clinic, and the incorporation of DDSs may further increase antitumor efficiency while decreasing adverse side effects. This review focuses on the use of nano-, micro-, and macroscale DDSs for co-delivery of different immunostimulatory factors to reprogram the immune system to combat cancer. Regarding to nanoparticle-based DDSs, we emphasize the nanoparticle-based tumor immune environment modulation or as an addition to gene therapy, photodynamic therapy, or photothermal therapy. For microparticle or capsule-based DDSs, an overview of the carrier type, fabrication approach, and co-delivery of tumor vaccines and adjuvants is introduced. Finally, macroscale DDSs including hydrogels and scaffolds are also included and their role in personalized vaccine delivery and adoptive cell transfer therapy are described. Perspective and clinical translation of DDS-based cancer immunotherapy is also discussed. We believe that DDSs hold great potential in advancing the fundamental research and clinical translation of cancer immunotherapy. STATEMENT OF SIGNIFICANCE: Immunotherapy is moving to the frontier of cancer treatment. Drug delivery systems (DDSs) have greatly advanced the development of cancer immunotherapeutic regimen and combination treatment. In this comprehensive review, we focus on the use of nano-, micro-, and macroscale DDSs for the co-delivery of different immunostimulatory factors to reprogram the immune system to combat cancer. We also propose the perspective on the development of next-generation DDS-based cancer immunotherapy. This review indicates that DDSs can augment the antitumor T-cell immunity and hold great potential in advancing the fundamental research and clinical translation of cancer immunotherapy by simultaneously delivering dual or multiple immunostimulatory drugs.

Abstract
Constructing intracellular degradable drug delivery vehicles is critical to fully exert the function of loaded drugs. Considering the poly (amino acid) is sensitively degradable to acid and enzyme which indwell in the mature lysosome, we here presented the poly(amino acid) capsules constructed by the synthetic poly(amino acid), (poly-glutamic acid, PGA and poly-ornithine, POR). The fabrication of Dox loaded poly (amino acid) capsules was demonstrated, and was thoroughly characterized by various techniques, including Zetasizer, SEM, TEM, fluorescent microscopy, and confocal laser scan microscopy. By controlling fabrication process, we tuned the carriers with different physical properties (charges and stiffness). Then, we thoroughly investigated the effects of these properties on the intracellular uptake and anti-cancer abilities of various carriers@Dox. In addition, the degradability of poly(amino acid) capsules was studied to reveal the release profiles of the carriers with or without templates from the side aspect. We found the positively charged and stiffer carriers mainly contributed to the cellular uptake process and amount, while both the uptake amount and degradability of the endocytosed carriers@Dox played a critical role on the cytotoxicity. We believe the findings here could pave the way for designing poly(amino acid) capsules or other degradable polymers based on poly(amino acid) as the drug delivery vehicles.

Abstract
Enzymatic destruction of adipose tissue has been achieved by encapsulation of lipase into the polymeric microcapsules. Adipose tissue destruction was delayed while lipase is encapsulated comparing with the direct lipase action as demonstrated by optical microscopy and optical coherence tomography in in vitro studies. Raman spectroscopy confirms that triglycerides in fat tissue were cleaved into free fatty acids, glycerol, and possible di- and monoglyceride residues. The results underpin the concept of local and controlled treatment of tissues via encapsulation. Effect of lipase encapsulation into the polymeric microcapsules on adipose tissue destruction compared to free lipase application.

Abstract
The delivery of probiotic microorganisms as food additives via oral administration is a straightforward strategy to improve the intestinal microbiota. To protect probiotics from the harsh environments in the stomach and small intestine, it is necessary to formulate them in biocompatible carriers, which finally release them in the ileum and colon without losing their viability and functions. Despite major progresses in various polymer-based formulations, many of them are highly heterogeneous and too large in size and hence often "felt" by the tongue. In this study, we established a new formulation for probiotics Lactobacillus rhamnosus GG (LGG) and systematically correlated the physicochemical properties of formulations with the functions of probiotics after the delivery to different gastrointestinal compartments. By reducing the stirring speed by 1 order of magnitude during the emulsification of polyalginate in the presence of xanthan gum, we fabricated microparticles with a size well below the limit of human oral sensory systems. To improve the chemical stability, we deposited chitosan and polyalginate layers on particle surfaces and found that the deposition of a 20 nm-thick layer is already sufficient to perfectly sustain the viability of all LGG. Compared to free LGG, the colony-forming units of LGG in these formulations were by factors of 107 larger in stomach fluid and 104 larger in small intestine fluid. The metabolic functionality of LGG in polymer formulations was assessed by measuring the amount of lactate produced by LGG in a human gastrointestinal simulator, showing 5 orders of magnitude larger values compared to free LGG. The obtained results have demonstrated that the minimal formulation of LGG established here boosts not only the viability but also the metabolic functionality of probiotics throughout oral uptake, passage through the gastrointestinal tract, and delivery to the ileum and colon.

Abstract
Vaccines and immunotherapies that elicit specific types of immune responses offer transformative potential to tackle disease. The mechanisms governing the processing of immune signals-events that determine the type of response generated-are incredibly complex. Understanding these processes would inform more rational vaccine design by linking carrier properties, processing mechanisms, and relevant timescales to specific impacts on immune response. This goal is pursued using nanostructured materials-termed immune polyelectrolyte multilayers-built entirely from antigens and stimulatory toll-like receptors agonists (TLRas). This simplicity allows isolation and quantification of the rates and mechanisms of intracellular signal processing, and the link to activation of distinct immune pathways. Each vaccine component is internalized in a colocalized manner through energy-dependent caveolae-mediated endocytosis. This process results in trafficking through endosome/lysosome pathways and stimulation of TLRs expressed on endosomes/lysosomes. The maximum rates for these events occur within 4 h, but are detectable in minutes, ultimately driving downstream proimmune functions. Interestingly, these uptake, processing, and activation kinetics are significantly faster for TLRas in particulate form compared with free TLRa. Our findings provide insight into specific mechanisms by which particulate vaccines enhance initiation of immune response, and highlight quantitative strategies to assess other carrier technologies.

Abstract
Microencapsulation techniques represent a critical step in realizing highly controlled transport of functional materials in multiphase systems. The first demonstration of microcapsules prepared from minimally grafted silk ionomers (silk fibroin modified with cationic/anionic charge groups) are presented here. These tailored biomacromolecules have shown significantly increased biocompatibility over traditional polyelectrolytes and heavily grafted silk ionomers, but the low grafting density had previously limited attempts to fabricate stable microcapsules. In addition, the first microcapsules from polyethylene-glycol-grafted silk ionomers are fabricated and the corresponding impact on microcapsule behavior is demonstrated. The materials are shown to exhibit pH-responsive properties, with the microcapsules demonstrating an approx. tenfold decrease in stiffness and an approx. threefold change in diffusion coefficient when moving from acidic to basic buffer. Finally, the effect of assembly conditions of the microcapsules are shown to play a large role in determining final properties, with microcapsules prepared in acidic buffers showing lower roughness, stiffness, and an inversion in transport behavior (i.e., permeability decreases at higher pH).

Abstract
Nano- and microcarriers as vehicles for active agents are applied to support them to reach their target in a defined, specific, and protected way. This implies not only a safe transport of agents towards the desired cell type or tissue but also the intracellular processing of the carrier: in particular, release of the incorporated carriers into the cytoplasm is a prerequisite for the successful subsequent delivery of most active agents and is often impeded by endolysosomal degenerative enzymes. We address this issue by using the layer-by-layer strategy of carrier assembly offering the opportunity to independently integrate and carry active agents but also specific agents preventing endolysosomal acidification. The weak base chloroquine (CQ) was investigated as a multilayer, template and capsule constituent regarding its ability to delay endolysosomal acidification and prolong the tolerable time frame in endolysosomes, which allows the carrier to finally escape into the cytoplasm. As a model and reporter active agent, plasmid encoding enhanced green fluorescent protein was used as a multilayer-assembly component to illustrate the cytoplasmic release of the intact carrier by final expression of the green fluorescent protein. Integrating CQ into the carrier, GFP expression could be strongly increased and a transfection efficiency of up to 20% could be obtained. This represents a very high transfection rate for a drug delivery system reached by only one additional reagent that has no further influence on the activity of the transported drug and cell viability, offering a significantly enhanced delivery efficiency.

Abstract
The breakthrough of genetic therapy is set back by the lack of suitable genetic vector systems. We present the development of permeability-tunable, capsule-like, polymeric, micron-sized, core-shell particles for delivery of recombinant nucleic acids into target cells. These particles were demonstrated to effectively release rod-shaped small hairpin RNA and to selectively retain the RNA-encoding DNA template, which was designed to form a bulky tripartite structure. Thus, they can serve as delivery vectors preloaded with cargo RNA or alternatively as RNA-producing micro-bioreactors. The internalization of particles by human tissue culture cells inversely correlated with particle size and with the cell to particle ratio, although at a higher than stoichiometric excess of particles over cells, cell viability was impaired. Among primary human peripheral blood mononuclear cells, up to 50% of the monocytes displayed positive uptake of particles. Finally, these particles efficiently delivered siRNA into HEK293T cells triggering functional knockdown of the target gene lamin A/C. Particle-mediated knockdown was superior to that observed after conventional siRNA delivery via lipofection. Core-shell particles protect encapsulated nucleic acids from degradation and target cell genomes from direct contact with recombinant DNA, thus representing a promising delivery vector system that can be explored for genetic therapy and vaccination.

Abstract
Microcapsules made of polyelectrolyte multilayers exhibit no or low toxicity, appropriate mechanical stability, variable controllable degradation and can incorporate remote release mechanisms triggered by various stimuli, making them well suited for targeted drug delivery to live cells. This study investigates interactions between microcapsules made of synthetic (i.e. polystyrenesulfonate sodium salt/polyallylamine hydrochloride) or natural (i.e. dextran sulfate/poly-L-arginine) polyelectrolyte and human umbilical vein endothelial cells with particular focus on the effect of the glycocalyx layer on the intake of microcapsules by endothelial cells. Neuraminidase cleaves N-acetyl neuraminic acid residues of glycoproteins and targets the sialic acid component of the glycocalyx on the cell membrane. Three-dimensional confocal images reveal that microcapsules, functionalized with neuraminidase, can be internalized by endothelial cells. Capsules without neuraminidase are blocked by the glycocalyx layer. Uptake of the microcapsules is most significant in the first 2 h. Following their internalization by endothelial cells, biodegradable DS/PArg capsules rupture by day 5; however, there is no obvious change in the shape and integrity of PSS/PAH capsules within the period of observation. Results from the study support our hypothesis that the glycocalyx functions as an endothelial barrier to cross-membrane movement of microcapsules. Neuraminidase-loaded microcapsules can enter endothelial cells by localized cleavage of glycocalyx components with minimum disruption of the glycocalyx layer and therefore have high potential to act as drug delivery vehicles to reach tissues beyond the endothelial barrier of blood vessels.

Abstract
Encapsulation of pH sensitive fluorophores as reporting molecules provides a powerful approach to visualize the transportation of multilayer capsules. In this study, two pH sensitive dyes (fluorescein and oregon green) and one pH insensitive dye (rhodamine B) were simultaneously labeled on the microcapsules to fabricate ratiometric pH sensors. The fluorescence of the triple-labeled microcapsule sensors was robust and nearly independent of other intracellular species. With a dynamic pH measurement range of 3.3-6.5, the microcapsules can report their localized pH at a real time. Cell culture experiments showed that the microcapsules could be internalized by RAW 246.7 cells naturally and finally accumulated in acidic organelles with a pH value of 5.08 ± 0.59 (mean ± s.d.; n=162).

Abstract
Autofluorescent microcapsules were assembled by covalent cross-linking of polysaccharide alginate dialdehyde (ADA) derivative and cystamine dihydrochloride (CM) through a layer-by-layer (LBL) technique. The formulated Schiff base and disulfide bonds render capsules with pH- and redox-responsive properties for pinpointed intracellular delivery based on the physiological difference between intracellular and extracellular environments. This simple and versatile method could be extended to other polysaccharide derivatives for the fabrication of autofluorescent nano- and micromaterials with dual stimuli response for biomedical applications.

Abstract
Engineered nanoparticles have been designed based on the self-assembling properties of synthetic coiled-coil lipopeptide building blocks. The presence of an isoleucine zipper within the lipopeptide together with the aggregating effects of an N-terminal lipid drives formation of 20-25 nm nanoparticles in solution. Biophysical studies support a model in which the lipid is buried in the centre of the nanoparticle, with 20-30 trimeric helical coiled-coil bundles radiating out into solution. A promiscuous T-helper epitope and a synthetic B-cell epitope mimetic derived from the circumsporozoite protein of Plasmodium falciparum have been linked to each lipopeptide chain, with the result that 60-90 copies of each antigen are displayed over the surface of the nanoparticle. These nanoparticles elicit strong humoral immune responses in mice and rabbits, including antibodies able to cross-react with the parasite, thereby, supporting the potential value of this delivery system in synthetic vaccine design.
