1. An emerging material “PICsome”: A hot zone between “PEG” and “PEG”

Recently, nanomaterials constructed by molecular self-assembly have gathered much attention to develop nano-devices incorporated with many types of drugs. Particularly, hollow capsules are one of promising materials, and recently, we have developed polyion complex vesicles, PICsomes, as novel polymeric vesicles. The most advantageous feature of PICsomes is its simple preparation process: Typically, they can be prepared by simple mixing of oppositely charged block copolymers consisting of poly(ethylene glycol) (PEG) and charged poly(amino acid)s in an aqueous medium. Moreover, many other unique properties of PICsomes have been reported, such as facile tuning of vesicle sizes ranging from 100–400 nm while keeping monodispersed size distribution, semipermeable vesicle membrane, facile loading of various water-dispersed materials, long blood circulation after crosslinking, excellent tumor accumulation based on the enhanced permeability and retention (EPR) effect, and so on. The present review article describes basic design and synthetic strategy of PICsomes, fundamental properties of PICsomes, and recent applications of PICsomes to drug delivery system..

Herein, we review nanodevice approaches, including liposomes, nanoparticles and polymeric nanoassemblies, such as polymeric micelles and vesicles, which can precisely control their structure and functions for specifically interacting with cells and tissues. These systems have been successfully used for the selective delivery of reporter and therapeutic agents to specific tissues with controlled cellular and subcellular targeting of biomolecules and programmed operation inside the body, suggesting a high potential for developing the analysis for nano- pathophysiology..
3. Akihiro Kishimura, Development of polyion complex vesicles (PICsomes) from block copolymers for biomedical applications, Polymer Journal, 2013.04, [URL], Polyion complex (PIC) formation is one of the most powerful techniques for obtaining molecular self-assemblies in aqueous media. The simple preparation process based on multiple electrostatic interactions is quite attractive for material syntheses, as well as biomedical applications. Therefore, it is desirable to control PIC architectures at the nanoscale in order to expand the scope of PIC materials. In this review article, recent progress on PIC vesicles (PICsomes) is summarized. PICsomes were first developed by my research group, and we recently succeeded in controlling the sizes and structural uniformity of the vesicles. Furthermore, the characteristic dynamic nature of PICs was revealed: PICs were found to exhibit reversible association/ dissociation and structural transformation. We demonstrated that crosslinking the PIC layers of PICsomes is a powerful method for tuning properties such as stability and permeability. Finally, the potential utility of PICsomes for drug delivery nanocarriers was examined, and their future biomedical application is discussed..

First, the polyion component structures were carefully designed to facilitate a multimolecular (or secondary) association of unit PICs for noncovalent (or chemical cross-linking-free) stabilization of vesicular PICs. Chemically modified, single-stranded oligonucleotides (SSOs) dramatically stabilized the multimolecular associates under physiological conditions, compared to control SSOs without chemical modifications and duplex oligonucleotides. In addition, a high degree of guanidino groups in the polypeptide segment was also crucial for the high stability of multimolecular associates. Dynamic light scattering and transmission electron microscopy revealed the stabilized multimolecular associates to have a 100 nm sized vesicular architecture with a narrow size distribution. The loading number of SSOs per nanovesicle was determined to be ∼2500 using fluorescence correlation spectroscopic analyses with fluorescently labeled SSOs. Furthermore, the nanovesicle stably encapsulated ribonuclease H (RNase H) as an effector enzyme at ∼10 per nanovesicle through simple vortex-mixing with preformed nanovesicles. Ultimately, the RNase H-encapsulated nanovesicle efficiently delivered SSOs with RNase H into cultured cancer cells, thereby eliciting the significantly higher gene knockdown compared with empty nanovesicles (without RNase H) or a mixture of nanovesicles with RNase H without encapsulation. These results demonstrate the great potential of noncovalently stabilized nanovesicles for the codelivery of two varying bio-macromolecule payloads for ensuring their cooperative biological activity..

The siRNAsome membrane was revealed to consist of PIC units fulfilling a simple molar ratio (1:2 or 2:3) of block catiomer and siRNA. These ratios correspond to the minimal integer molar ratio to maximally compensate the charge imbalance of PIC, because the numbers of charges per block catiomer and siRNA are +70 and -40, respectively. Accordingly, the ζ-potentials of siRNAsomes prepared at 1:2 and 2:3 were negative and positive, respectively. Cross-section transmission electron microscopic observation clarified that the membrane thicknesses of 1:2 and 2:3 siRNAsomes were 11.0 and 17.2 nm, respectively. Considering that a calculated long-axial length of siRNA is 5.9 nm, these thickness values correspond to the membrane models of two (11.8 nm) and three (17.7 nm) tandemly aligned siRNAs associating with one and two block catiomers, respectively. For biological application, siRNAsomes were stabilized through membrane-cross-linking with glutaraldehyde. The positively charged and cross-linked siRNAsome facilitated siRNA internalization into cultured cancer cells, eliciting significant gene silencing with negligible cytotoxicity. The siRNAsome stably encapsulated dextran as a model cargo macromolecule in the cavity by simple vortex mixing. Confocal laser scanning microscopic observation displayed that both of the payloads were internalized together into cultured cells. These results demonstrate the potential of siRNAsomes as a versatile platform for codelivery of siRNA with other cargo macromolecules..
4. Mao Hori, Horacio Cabral, Kazuko Toh, Akihiro Kishimura, Kazunori Kataoka, Robust Polyion Complex Vesicles (PICsomes) under Physiological Conditions Reinforced by Multiple Hydrogen Bond Formation Derived by Guanidinium Groups, Biomacromolecules, 10.1021/acs.biomac.8b01097, 19, 10, 4113-4121, 2018.10, Polyion complex vesicles (PICsomes) formed from a self-assembly of an oppositely charged pair of block- and homo-polyelectrolytes have shown exceptional features for functional loading of bioactive agents. Nevertheless, the stability of PICsomes is often jeopardized in a physiological environment, and only PICsomes having chemically cross-linked membranes have endured in harsh in vivo conditions, such as in the bloodstream. Herein, we developed versatile PICsomes aimed to last in in vivo settings by stabilizing their membrane through a combination of ionic and hydrogen bonding, which is widely found in natural proteins as a salt bridge, by controlled introduction of guanidinium groups in the polycation fraction toward concurrent polyion complexation and hydrogen bonding. The guanidinylated PICsomes were successfully assembled under physiological salt conditions, with precise control of their morphology by tuning the guanidinium content, and the ratio of anionic and cationic components. Guanidinylated PICsomes with 100 nm diameter, which are relevant to nanocarrier development, were stable in high urea concentration, at physiological temperature, and under serum incubation, persisting in blood circulation in vivo..

The treatment strategies are limited to surgical or endovascular procedures for final stage chronic PAD or acute limb ischemia, and no pharmacological approaches have been achieved to prevent the worsening of chronic PAD or to regenerate the tissues of acute limb ischemia. Therefore, the improvement of therapeutic strategy is strongly demanded in clinics. Here, we adopted an acute hindlimb ischemia model in rats, which provides concomitant inflammatory response, to evaluate the application of drug delivery system against PAD. Through comparative experiments by using different-sized nanomedicine analogues, polyion complex (PIC) micelles with 30 nm diameter and PIC vesicles with 100- and 200-nm diameter (PICs-30, −100, −200 respectively), we found the size-dependent accumulation and retention in the collateral arteries. In contrast to PICs-30 and -200, histological analysis showed that PICs-100 were around the arterioles and co-localized with macrophages, which indicates that the PICs-100 can achieve moderate interaction with phagocytes. Our data suggests that controlling the size of nanomedicines has promise for developing novel angiogenic treatments toward the effective management of collateral arteries..
6. Omer F. Mutaf, Yasutaka Anraku, Akihiro Kishimura, Kazunori Kataoka, Unilamellar polyion complex vesicles (PICsomes) with tunable permeabilities for macromolecular solutes with different shapes and sizes, Polymer, 10.1016/j.polymer.2017.10.062, 133, 1-7, 2017.12, Polyion complex vesicles (PICsomes) are characterized by their unique three-layered semipermeable nanomembrane structures, in which a unilamellar PIC layer is sandwiched by poly(ethylene glycol) layers, and have gathered much attention as nano-scaled drug vehicles. Herein, the crosslinking degree of the nanomembrane in the PICsome was controlled systematically for the first time. Permeability of the PICsome nanomembrane was evaluated through a kinetic study of the release of macromolecular cargoes from the PICsome. The degree of crosslinking in the nanomembrane successfully regulated the release behavior. Moreover, the shape and size of the macromolecular solutes were found to be critical factors determining their transport from the inner aqueous phase of the PICsome to the external environment. The results indicate that the unique three-layered structure of PICsome membranes plays a key role in modulating solute transport. These findings will provide a rational strategy for the development of nanomembrane-based controlled-release systems..

We have succeeded in preparing enzyme-loaded polyion complex vesicles (PICsomes) through a facile protein- loading method. The preservation of enzyme activity was confirmed even after cross-linking of the PICsomes. The cross- linked b-galactosidase-loaded PICsomes (beta-gal@PICsomes) selectively accumulated in the tumor tissue of mice. Moreover, a model prodrug, HMDER-betaGal, was successfully converted into a highly fluorescent product, HMDER, at the tumor site, even 4days after administration of the beta-gal@PICsomes. Intravital confocal microscopy showed continuous production of HMDER and its distribution throughout the tumor tissues. Thus, enzyme-loaded PICsomes are useful for prodrug activation at the tumor site and could be a versatile platform for enzyme delivery in enzyme prodrug therapy..
