Abstract
Protein nanotubes (PNTs) as state-of-the-art nanocarriers are promising for various potential applications both in the food and pharmaceutical industries. Derived from edible starting sources like α-lactalbumin, lysozyme, and ovalbumin, PNTs bear properties of biocompatibility and biodegradability. Their large specific surface area and hydrophobic core facilitate chemical modification and loading of bioactive substances, respectively. Moreover, their enhanced permeability and penetration ability across biological barriers such as intestinal mucus, extracellular matrix, and thrombus clot, make it promising platforms for health-related applications. Most importantly, their simple preparation processes enable large-scale production, supporting applications in the biomedical and nanotechnological fields. Understanding the self-assembly principles is crucial for controlling their morphology, size, and shape, and thus provides the ground to a multitude of applications. Here, the current state-of-the-art of PNTs including their building materials, physicochemical properties, and self-assembly mechanisms are comprehensively reviewed. The advantages and limitations, as well as challenges and prospects for their successful applications in biomaterial and pharmaceutical sectors are then discussed and highlighted. Potential cytotoxicity of PNTs and the need of regulations as critical factors for enabling in vivo applications are also highlighted. In the end, a brief summary and future prospects for PNTs as advanced platforms and delivery systems are included.

[PMID: 37570533 PMCID: PMC10421347 DOI: 10.3390/nano13152215] [Citation(s) in RCA: 5] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/17/2023] [Revised: 07/24/2023] [Accepted: 07/26/2023] [Indexed: 08/13/2023]
Abstract
Both biomedical applications and safety assessments of manufactured nanomaterials require a thorough understanding of the interaction between nanomaterials and cells, including how nanomaterials enter cells, transport within cells, and leave cells. However, compared to the extensively studied uptake and trafficking of nanoparticles (NPs) in cells, less attention has been paid to the exocytosis of NPs. Yet exocytosis is an indispensable process of regulating the content of NPs in cells, which in turn influences, even decides, the toxicity of NPs to cells. A comprehensive understanding of the mechanisms and influencing factors of the exocytosis of NPs is not only essential for the safety assessment of NPs but also helpful for guiding the design of safe and highly effective NP-based materials for various purposes. Herein, we review the current status and progress of studies on the exocytosis of NPs. Firstly, we introduce experimental procedures and considerations. Then, exocytosis mechanisms/pathways are summarized with a detailed introduction of the main pathways (lysosomal and endoplasmic reticulum/Golgi pathway) and the role of microtubules; the patterns of exocytosis kinetics are presented and discussed. Subsequently, the influencing factors (initial content and location of intracellular NPs, physiochemical properties of NPs, cell type, and extracellular conditions) are fully discussed. Although there are inconsistent results, some rules are obtained, like smaller and charged NPs are more easily excreted. Finally, the challenges and future directions in the field have been discussed.

Abstract
The oral route has long been recognized as the most preferred route for drug delivery as it offers high patient compliance and requires minimal expertise. Unlike small molecule drugs, the harsh environment of the gastrointestinal tract and low permeability across the intestinal epithelium make oral delivery extremely ineffective for macromolecules. Accordingly, delivery systems that are rationally constructed with suitable materials to overcome barriers to oral delivery are exceptionally promising. Among the most ideal materials are polysaccharides. Depending on the interaction between polysaccharides and proteins, the thermodynamic loading and release of proteins in the aqueous phase can be realized. Specific polysaccharides (dextran, chitosan, alginate, cellulose, etc.) endow systems with functional properties, including muco-adhesiveness, pH-responsiveness, and prevention of enzymatic degradation. Furthermore, multiple groups in polysaccharides can be modified, which gives them a variety of properties and enables them to suit specific needs. This review provides an overview of different types of polysaccharide-based nanocarriers based on different kinds of interaction forces and the influencing factors in the construction of polysaccharide-based nanocarriers. Strategies of polysaccharide-based nanocarriers to improve the bioavailability of orally administered proteins/peptides were described. Additionally, current restrictions and future trends of polysaccharide-based nanocarriers for oral delivery of proteins/peptides were also covered.

Abstract
Nanocarriers have become an effective strategy to overcome epithelial absorption barriers. During the absorption process, the endocytosis mechanisms, cell internalization pathways, and transport efficiency of nanocarriers are greatly impacted by their physical properties. To understand the relationship between physical properties of nanocarriers and their abilities overcoming multiple absorption barriers, nanocarriers with variable physical properties were prepared via self-assembly of hydrolyzed α-lactalbumin peptide fragments. The impacts of size, shape, and rigidity of nanocarriers on epithelial cells endocytosis mechanisms, internalization pathways, transport efficiency, and bioavailability were studied systematically. The results showed that nanospheres were mainly internalized via clathrin-mediated endocytosis, which was then locked in lysosomes and degraded enzymatically in cytoplasm. While macropinocytosis was the primary pathway of nanotubes and transported to the endoplasmic reticulum and Golgi apparatus, resulting in a high drug concentration and sustained release in cytoplasm. Besides, nanotubes can overcome the multi-drug resistance by inhibiting the P-glycoprotein efflux. Furthermore, nanotubes can open intercellular tight-junctions instantaneously and reversibly, which promotes transport into blood circulation. The aqueous solubility of hydrophobic bioactive mangiferin (Mgf) was improved by nanocarriers. Most importantly, the bioavailability of Mgf was the highest for cross-linked short nanotube (CSNT) which outperformed free Mgf and other formulations by in vivo pharmacokinetic studies. Finally, Mgf-loaded CSNT showed an excellent therapeutic efficiency in vivo for the intervention of streptozotocin-induced diabetes. These results indicate that cross-linked α-lactalbumin nanotubes could be an effective nanocarrier delivery system for improving the epithelium cellular absorption and bioavailability of hydrophobic bioactive compounds.

Abstract
The blood-brain barrier (BBB) is a brain protection structure that restricts drug delivery from the blood to the central nervous system. Thus, we developed a novel drug carrier using yeast vacuoles to overcome this problem. The purpose of this study was to assess the drug transportability of yeast vacuoles using a human cerebral microvascular endothelial cell line (hCMEC/D3) cell monolayer. Here, we used daunorubicin (DNR) as a microtubule-targeting agent with the ability to disaggregate pre-formed fibrils and prevent Tau fibrillization. An in vitro model was developed by culturing hCMEC/D3 cells on Transwell inserts in EBM-2 endothelial basal medium until the cells formed a monolayer. Next, nano-sized yeast vacuoles were loaded with DNR, and the signals inside and outside the hMEC/D3 cell monolayer were detected using the GloMax® Explorer fluorometer. DNR penetrated the cell monolayer and was regulated by endocytosis via receptor-mediated macropinocytosis on the surface of the cell. Confocal imaging showed a significant increase in intracellular DNR fluorescence when the cells were treated with the vacuole-encapsulated drug. These results indicate that the drug penetrated the hCMEC/D3 cell monolayer via encapsulation into the vacuoles. Overall, yeast-derived vacuoles are promising candidates as drug carriers to the brain.

Abstract
Background
Increasing brain exposure of biotherapeutics is key to success in central nervous system disease drug discovery. Accessing the brain parenchyma is especially difficult for large polar molecules such as biotherapeutics and antibodies because of the blood-brain barrier. We investigated a new immunization strategy to identify novel receptors mediating transcytosis across the blood-brain barrier.
Method
We immunized mice with primary non-human primate brain microvascular endothelial cells to obtain antibodies. These antibodies were screened for their capacity to bind and to be internalized by primary non-human primate brain microvascular endothelial cells and Human Cerebral Microvascular Endothelial Cell clone D3. They were further evaluated for their transcytosis capabilities in three in vitro blood-brain barrier models. In parallel, their targets were identified by two different methods and their pattern of binding to human tissue was investigated using immunohistochemistry.
Results
12 antibodies with unique sequence and internalization capacities were selected amongst more than six hundred. Aside from one antibody targeting Activated Leukocyte Cell Adhesion Molecule and one targeting Striatin3, most of the other antibodies recognized β1 integrin and its heterodimers. The antibody with the best transcytosis capabilities in all blood-brain barrier in vitro models and with the best binding capacity was an anti-αnβ1 integrin. In comparison, commercial anti-integrin antibodies performed poorly in transcytosis assays, emphasizing the originality of the antibodies derived here. Immunohistochemistry studies showed specific vascular staining on human and non-human primate tissues.
Conclusions
This transcytotic behavior has not previously been reported for anti-integrin antibodies. Further studies should be undertaken to validate this new mechanism in vivo and to evaluate its potential in brain delivery.

Abstract
Integrins are transmembrane proteins that are most typically thought of as integrating adhesion to the extracellular matrix with intracellular signaling and cell regulation. Traditionally, integrins are found at basolateral and lateral cell surfaces where they facilitate binding to the ECM and intercellular adhesion through cytosolic binding partners that regulate organization of actin microfilaments. However, evidence is accumulating that integrins also are apically localized, either endogenously or due to an exogenous stimulus. Apically localized integrins have been shown to regulate several processes by interacting with proteins such as connexins, tight junction proteins, and polarity complex proteins. Integrins can also act as receptors to mediate endocytosis. Here we review these newly appreciated roles for integrins localized to the apical cell surface.

Abstract
Oral administration is the most commonly used route for drug delivery owing to its cost-effectiveness, ease of administration, and high patient compliance. However, the absorption of orally delivered compounds is a complex process that greatly depends on the interplay between the characteristics of the drug/formulation and the gastrointestinal tract. In this contribution, we review the different preclinical models (in vitro, ex vivo and in vivo) from their development to application for studying the transport of drugs across intestinal barriers. This review also discusses the advantages and disadvantages of each model. Furthermore, the authors have reviewed the selection and validation of these models and how the limitations of the models can be addressed in future investigations. The correlation and predictability of the intestinal transport data from the preclinical models and human data are also explored. With the increasing popularity and prevalence of orally delivered drugs/formulations, sophisticated preclinical models with higher predictive capacity for absorption of oral formulations used in clinical studies will be needed.

Abstract
Ligand-modified nanoparticles (NPs) have been widely used in oral drug delivery systems to promote endocytosis on intestinal epithelia. However, their transcytosis across the intestinal epithelia is still limited. Except for complex intracellular trafficking, recycling again from the apical sides into the intestinal lumen of the endocytosed NPs cannot be ignored. In this study, we modified NP surfaces with angiopep-2 (ANG) that targeted the low-density lipoprotein receptor-related protein 1 (LRP-1) expressed on the intestine to increase both the apical endocytosis and basolateral transcytosis of NPs. Notably, our finding revealed that ANG NPs could increase the apical expression and further basolateral redistribution of LRP-1 on Caco-2 cells, thus generating an apical-to-basolateral absorption pattern. Because of the enhanced transcytosis, insulin loaded ANG NPs possessed much stronger absorption efficiency and induced maximal blood glucose reduction to 61.46% in diabetic rats. Self-regulating the distribution of receptors on polarized intestine cells to promote basolateral transcytosis will provide promising insights for the rational design of oral delivery systems of protein/peptide drugs.

Abstract
Intestinal epithelial cells are the primary biological barriers for orally administrated nano-formulations and the delivered protein drugs. Thereinto, besides the cellular uptake, intracellular trafficking pathway and the related exocytosis are of great importance to the trans-epithelial transport of drug-loaded NPs. Herein, inspired by the physiological functions of Golgi apparatus for secreting proteins out of cells, Golgi localization-related amino acid l-cysteine (Cys) was modified on the surface of NPs to see whether and how this modification could guide the Golgi pathway-related transport and facilitate the exocytosis of drug-loaded NPs. Meanwhile, cell-penetrating peptide octa-arginine (R8) was co-modified to increase the cellular uptake. The proportion of R8 and Cys modification was explored to get the best effect of endocytosis and exocytosis of NPs. As a result, 25%R8 + 75%Cys NPs with most Cys modification showed efficient transcytosis with the highest transcytosis/endocytosis ratio (0.87). Interestingly, exocytosis mechanism studies indicated that they trafficked through the Golgi secretory pathway and bypassed lysosomes due to Cys modification. The detailed Golgi position mechanism studies further suggested that the thiol group from Cys was important for mediating Golgi transport. In particular, competitive inhibition studies demonstrated that Cys-modified NPs were more conducive to their exocytosis after being transported through the Golgi secretory pathway. We proved that cargos transported via Golgi apparatus tended to be trafficked out of the cells and avoid degradation, which contributed to the transcytosis of 25%R8 + 75%Cys NPs in vitro. Inspiringly, compared with unmodified NPs, 25%R8 + 75%Cys NPs also exhibited promoted intestinal penetration and oral absorption in vivo. Oral delivery of insulin-loaded 25%R8 + 75%Cys NPs showed stronger hypoglycemic effects in diabetic rats. In summary, this work provides a strategy for complying with the physiological functions of Golgi apparatus for secreting to facilitate the exocytosis of NPs, thus further improving the oral absorption of loaded protein drugs.

Abstract
Diabetes mellitus (DM) has become an epidemic disorder that is an escalating public health risk. Currently, DM treatment is highly challenging due to temporary medical relief rather than a permanent cure. This article reports a ligand-anchored mixed micellar system formed by phospholipids and N -oleoyl-D-galactosamine aiming to enhance the oral bioavailability and hypoglycemic effects of berberine, an antidiabetic agent with poor absorption. Berberine-loaded mixed micelles (BBMMs) were prepared through a solvent diffusion technique. The resulting BB-MMs were characterized by particle size, potential, morphology, entrapment efficiency (EE) and in vitro release. The oral pharmacokinetics and hypoglycemic efficacy of BB-MMs were evaluated in rats and compared with a berberine suspension. As a result, BB-MMs prepared with the preferable formulation had a particle size of approximately 100 nm with an EE of over 85%. BB-MMs exhibited sustained drug release owing to the entrapment in the micelles. After oral administration, BB-MMs ameliorated the pharmacokinetic profile of berberine and significantly enhanced its oral bioavailability (317.17% relative to the suspension). The pharmacological effect (PE) of BB-MMs was approximately 3.44 times greater than that of the suspension. In addition, in situ single-pass intestinal perfusion and cellular testing results illustrated that BB-MMs had good intestinal permeability and cellular uptake. Our findings demonstrate that the oral bioavailability and hypoglycemic effects of berberine could be largely enhanced by encapsulation into mixed micelles with a galactose moiety. Thus, galactosylated micelles may be promising for developing berberine nanomedicines to fight DM.

Abstract
Glucose transporter (GLUT)-mediated transcytosis has been validated as an efficient method to cross the blood-brain barrier and enhance brain transport of nanomedicines. However, the transcytosis process remains elusive. Glycopeptide-modified nanodisks (Gly-A7R-NDs), which demonstrated high capacity of brain targeting via GLUT-mediated transcytosis in our previous reports, were utilized to better understand the whole transcytosis process. Gly-A7R-NDs internalized brain capillary endothelial cells mainly via GLUT-mediated/clathrin dependent endocytosis and macropinocytosis. The intracellular Gly-A7R-NDs remained intact, and the main excretion route of Gly-A7R-NDs was lysosomal exocytosis. Glycosylation of nanomedicine was crucial in GLUT-mediated transcytosis, while morphology did not affect the efficiency. This study highlights the pivotal roles of lysosomal exocytosis in the process of GLUT-mediated transcytosis, providing a new impetus to development of brain targeting drug delivery by accelerating lysosomal exocytosis.

Abstract
The intestinal epithelium is considered to be a major obstacle to the gastrointestinal administration for water-insoluble drugs. To enhance the intestinal absorption of paclitaxel by improving its solubility and overcoming the intestinal epithelium barrier, transferrin-modified paclitaxel nanocrystals were prepared based on the specific transferrin receptor expressed on the apical membrane of the intestinal epithelium and examined to exhibit a mean size of around 178 nm, a rod-like morphology, a sustained release property, and an enhanced in vitro antitumor effect. The in situ intestinal perfusion study proved that the intestinal absorption of transferrin-modified paclitaxel nanocrystals was remarkably enhanced compared with that of Taxol and unmodified paclitaxel nanocrystals, which was further evidenced by the result of pharmacokinetic study. Their transcytosis pathway and intracellular trafficking track were disclosed using Caco-2 cell monolayers. The transcytosis of transferrin-modified paclitaxel nanocrystals and unmodified paclitaxel nanocrystals was principally mediated by clathrin and lipid rafts. The colocalization of both paclitaxel nanocrystals with the organelles observed under confocal microscopy suggested that the late endosomes, lysosomes, ER, and Golgi apparatus played a part in the transcellular transport of both paclitaxel nanocrystals during their transcytosis. Therefore, the designed transferrin-modified drug nanocrystals might have a great potential in the enhancement of intestinal absorption of water-insoluble drugs.

Abstract
Brain delivery of nanoparticles and macromolecular drugs depends on blood-brain barrier (BBB)-permeable carriers. In this study, we searched for cyclic heptapeptides facilitating BBB permeation of M13 phages by phage library screening using a transcellular permeability assay with hCMEC/D3 cell monolayers, a human BBB model. The M13 phage, which is larger than macromolecular drugs and nanoparticles, served as a model macromolecule. The screen identified cyclic heptapeptide SLSHSPQ (SLS) as a human BBB-permeable peptide. The SLS-displaying phage (SLS-phage) exhibited improved permeation across the cell monolayer of monkey and rat BBB co-culture models. The SLS-phage internalized into hCMEC/D3 cells via macropinocytosis and externalized via the exosome excretion pathway. SLS-phage distribution into brain parenchyma was observed in mice after intravenous administration. Moreover, liposome permeated across the BBB as cyclic SLS peptide conjugates. In conclusion, the cyclic SLS heptapeptide is a novel carrier candidate for brain delivery of macromolecular drugs and nanoparticles.

Abstract
Oral administration of nanoparticles is extremely limited due to the two processes of mucus permeation and epithelial absorption, which requires completely opposite surface properties of the nanocarriers. To tackle the contradiction, we developed a rational strategy to modify the surface of mesoporous carbon nanoparticles with chitosan concealed by a hydrophilic N-(2-hydroxypropyl) methacrylamide copolymer (pHPMA) layer. Probucol (PB) with the low poor permeability and solubility was loaded in optimal nanocarriers to realize the high loading efficacy and controlled release. The pHPMA polymer is a hydrophilic "mucus-inert" material, which could be dissociable from the surface of nanoparticles in the mucus, thus promoting their mucus permeation and causing exposure of chitosan in transepithelial transport. The swelling effect of chitosan under acidic conditions allowed regulation of PB release behavior. In conclusion, the mucus-permeable nanocarrier could effectively overcome multiple gastrointestinal absorption barriers and the oral bioavailability of PB-loaded HCMCN was 2.76-fold that of commercial preparation.

Abstract
Methodology to enhance the intestinal absorption of peptides is an important challenge due to their easily degradation and poor permeability across the intestinal epithelium. In this study, the fish-derived peptide (DGDDGEAGKIG)-loaded chitosan (CS) nanoparticles (CS/PEP-NPs) were prepared and investigated in Caco-2 monolayer model. The results indicated zeta potential of CS/PEP-NPs increased with the increase in molecular weight of CS (10-50 kDa). Transmission electron microscopy images revealed the CS/PEP-NPs were uniform spherical-shaped nanoparticles with a diameter of 50-200 nm (150 kDa). Compared to other CS/PEP-NPs, 150-kDa CS/PEP-NPs performed an outstanding apparent permeability coefficient (Papp, 2.29 × 10-5 cm s-1 ) and cumulative amount of peptide (120 min, 2,987 ng) in Caco-2 cells. CS/PEP-NPs could reduce the tight junction integrity of Caco-2 cells and enhance the intracellular fluorescence intensities of fluorescein isothiocyanate-labeled peptide. These findings suggest that chitosan nanoparticles are promising carriers to promote intestinal absorption of fish-derived peptide via paracellular pathway mediated by tight junctions. PRACTICAL APPLICATIONS: Chitosans are promising carriers to promote intestinal absorption of fish-derived peptide. The 150-kDa CS/PEP-NPs performed an outstanding apparent permeability coefficient (Papp, 2.29 × 10-5 cm s-1 ) and cumulative amount of peptide (120 min, 2,987 ng) in Caco-2 cells. CS/PEP-NPs could reduce the tight junction integrity of Caco-2 cells and enhance the peptide uptake by paracellular pathway. Chitosan nanoparticles can be developed as vehicles for enhancing the cellular uptake of peptide in food industry.

Abstract
In oral delivery of biomacromolecules, ligand-modified nanoparticles (NPs) have emerged as a promising tool to improve the epithelial uptake of the loaded protein/peptide. Unfortunately, the stability and the transport mechanisms of the biotherapeutics during the intracellular transportation still remained unclear, leading to the poor transepithelial efficiency. Additionally, developing novel approaches to simultaneously monitor the payload bioactivity during the transport processes is veritably benefit for keeping their bioactivity. In the present study, EGP peptide (KRKKKGKGLGKKRDPCLRKYK), a ligand with high affinity to heparan sulfate proteoglycans (HSPGs), was found remarkably increasing the cellular uptake (4.5-fold) and also surprisingly achieving high transcytosis efficiency (4.2-fold) of poly(lactide- co-glycolide) NPs on Caco-2 cell monolayer. Compared with unmodified NPs (C NPs), EGP modified NPs (EGP NPs) exhibited more desirable colloidal stability within epithelia. In the subsequent study, the bioactivity of encapsulated insulin during the cellular transportation was innovatively monitored by a glucose consumption assay. Inspiringly, EGP NPs could mostly retain the bioactivity of loaded insulin whereas insulin from INS-C NPs was significantly degraded. Then the detailed mechanism study revealed that the binding of EGP to HSPGs played a vital role on NP transportation. Unlike C NPs being delivered in the endo/lysosomal pathway, EGP NPs were involved in caveolae-mediated transport, which contributes to the efficient avoidance of the lysosomal entrapment and sequentially facilitates the direct apical-to-basolateral transcytosis. The enhanced absorption of EGP NPs was confirmed in in situ intestinal loop models. Most importantly, oral administrated INS-EGP NPs generated a strong hypoglycemic response on diabetic rats with 10.2-fold and 2.6-fold increase in bioavailability compared with free insulin and INS-C NPs, respectively. The work provided an innovative strategy to monitor the payload bioactivity during the transport processes and proposed a novel aspect to increase oral bioavailability of biomacromolecules via improving payload stability and regulating the transcytosis pathway of nanocarriers.

Abstract
Although nanoparticles (NPs) have been demonstrated as promising tools for improving oral absorption of biotherapeutics, most of them still have very limited oral bioavailability. Lyso-endosomal degradation in epithelial cells is one of the important but often-neglected physiological barriers, limiting the transport of cargoes across the intestinal epithelium. We herein reported a solid lipid nanoparticle (SLN) platform with a unique feature of endosomal escape for oral protein drug delivery. The SLNs consisted of a solid-lipid shell, which contained an endosomal escape agent (GLFEAIEGFIENGWEGMIDGWYG, HA2), and an aqueous core that is loaded with insulin (INS HA2-O-SLNs). SLNs without and with the HA2 peptide in the aqueous core (INS SLNs and INS HA2-W-SLNs, respectively) were used as the control groups. Our study showed that INS HA2-O-SLNs effectively facilitated the escape of the loaded insulin from the acidic endosomes, which preserved the biological activity of insulin to a greater extent during the intracellular transport. The spatial location of the HA2 peptide was demonstrated to determine the endosomal escape efficiency. As demonstrated in the intracellular trafficking of SLNs, INS HA2-O-SLNs displayed much less distribution in late endosomes and lysosomes. Meanwhile, insulin in INS HA2-O-SLNs exhibited the highest transepithelial permeation efficiency, with 2.19 and 1.72 folds higher accumulated amount in the basolateral side as compared to that in INS SLNs and INS HA2-W-SLNs. In addition, insulin from INS HA2-O-SLNs exhibited the highest insulin permeation in various regions of small intestines. INS HA2-O-SLNs generated an excellent hypoglycemic response following oral administration in diabetic rats. Thus, such functional SLNs demonstrated a great potency for oral delivery of peptide/protein drugs.

Abstract
Ligand-modified nanoparticles (NPs) are an effective tool to increase the endocytosis efficiency of drugs, but these functionalized NPs face the drawback of "easy uptake hard transcytosis" in the oral delivery of proteins and peptides. Adversely, the resulting deficiency in transcytosis has not attracted much attention. Herein, NPs modified with the low-density lipoprotein receptor (LDLR) ligand NH2-C6-[cMPRLRGC]c-NH2, i.e., peptide-22 (P22NPs) were fabricated to investigate strategies related to the enhancement of transcytosis. By systematically studying the intracellular trafficking of NPs, it was found that reduced transcytosis might be associated with the entrapment of P22NPs in endosomes or lysosomes and limited basolateral exocytosis. On this basis, the prevention of the endolysosomal entrapment of NPs and the acceleration of basolateral exocytosis should be considered as strategies to enhance the transcytosis of NPs. By screening chemicals that could help the endosomal/lysosomal escape of chemicals related to LDLR-mediated transcytosis, it was shown that hemagglutinin-2 (HA2) and metformin had higher abilities to enhance the exocytosis of P22NPs. The transcytosis efficiencies of insulin loaded in P22NPs were also investigated, and a 3.2-fold increase in transcytosis was observed in comparison with free insulin. The transcytosis efficiencies of insulin could be further increased by the addition of metformin or HA2 (3.6-fold or 4.1-fold higher than that of free insulin). Inspiringly, the simultaneous addition of the abovementioned two chemicals led to the highest transcytosis efficiency of insulin, which was up to 5.1-fold higher than that of free insulin. These results demonstrated that endolysosomal entrapment and basolateral exocytosis are two of the most important limiting steps for the "easy uptake hard transcytosis" of orally administered ligand-modified NPs. Moreover, our work provides a new point of view for the design of novel oral drug delivery systems.

Abstract
To improve the oral efficiency of exenatide, we prepared polyethylene glycol-poly(lactic-co-glycolic acid) (PEG-PLGA) NPs modified with Fc (NPs-Fc) for exenatide oral delivery. Exenatide was encapsulated into the NPs by the w/o/w emulsion-solvent evaporation method. The particle size of the NPs-Fc was approximately 30 nm larger than that of the unmodified NPs with polydispersity indices in a narrow range (PDIs; PDI < 0.3) as detected by DLS, and the highest encapsulation efficiency of exenatide in the NPs was greater than 80%. Fc-conjugated NPs permeated Caco-2 cells faster and to a greater extent compared to unmodified NPs, as verified by CLSM and flow cytometry. Hypoglycemic effect studies demonstrated that oral administration of exenatide-loaded PEG-PLGA NPs modified by an Fc group extended the hypoglycemic effects compared with s.c. injection of the exenatide solution. Fluorescence-labeled NPs were used to investigate the effects of Fc targeting, and the results demonstrated that the NPs-Fc stayed in the gastrointestinal tract for a longer time in comparison with the unmodified NPs, as shown by the whole-body fluorescence images and fluorescence images of the dissected organs detected by in vivo imaging in live mice. Therefore, Fc-targeted nano-delivery systems show great promise for oral peptide/protein drug delivery.

Abstract
Oral administration of nanocarriers remains a significant challenge in the pharmaceutical sciences. The nanocarriers must efficiently overcome multiple gastrointestinal barriers including the harsh gastrointestinal environment, the mucosal layer, and the epithelium. Neutral hydrophilic surfaces are reportedly necessary for mucus permeation, but hydrophobic and cationic surfaces are important for efficient epithelial absorption. To accommodate these conflicting surface property requirements, we developed a strategy to modify nanocarrier surfaces with cationic cell-penetrating peptides (CPP) concealed by a hydrophilic succinylated casein (SCN) layer. SCN is a mucus-inert natural material specifically degraded in the intestine, thus protecting nanocarriers from the harsh gastric environment, facilitating their mucus permeation, and inducing exposure of CPPs after degradation for further effective transepithelial transport. Quantum dots doped hollow silica nanoparticles (HSQN) with a diameter around 180 nm was used as the nanocarrier and demonstrated as high as 50% loading efficacy of paclitaxel, a model drug with poor solubility and permeability. The dual layer modification strategy prevented premature drug leakage in stomach and maintained high mucus permeation (the trajectory spanned 9-fold larger area than single CPP modification). After intestinal degradation of SCN by trypsin, these nanocarriers exhibited strong interaction with epithelial membranes and a 5-fold increase in cellular uptake. Significant transepithelial transport and intestinal distribution were also observed for this dual-modified formulation. A pharmacokinetics study on the paclitaxel-loaded nanocarrier found 40% absolute bioavailability and 7.8-fold higher AUC compared to oral Taxol®. Compared with single CPP modified nanocarriers, our formulation showed increased in vivo efficacy and tumor accumulation of the model drug with negligible intestinal toxicity. In summary, sequential modification with CPP and SCN layers on HSQN offers a potential strategy to overcome the multiple barriers of the gastrointestinal tract. STATEMENT OF SIGNIFICANCE Oral administration of nanocarriers remains a big challenge due to the multiple gastrointestinal barriers. In order to achieve both strong mucus permeation and efficient epithelial absorption, we modified the surface of silica nanoparticles with two layers: cell penetrating peptide (CPP) layer and succinylated casein (SCN) layer. The newly developed nanoformulations are demonstrated to have the following advantages: 1) versatile carrier with easy preparation, 2) high drug loading especially for poor soluble molecules, 3) reduced drug leakage in the stomach, 4) effective mucus penetration and transepithelial transport and 5) good biocompatibility, which in all indicate a great potential of this bilayer-modification strategy to facilitate the oral delivery of therapeutic agents.

Abstract
Biomimetic nanocarriers are emerging as efficient vehicles to facilitate dietary absorption of biomacromolecules. In this study, two vitamins, thiamine and niacin, are employed to decorate liposomes loaded with insulin, thus facilitating oral absorption via vitamin ligand-receptor interactions. Both vitamins are conjugated with stearamine, which works to anchor the ligands to the surface of liposomes. Liposomes prepared under optimum conditions have a mean particle size of 125-150 nm and an insulin entrapment efficiency of approximately 30%-36%. Encapsulation into liposomes helps to stabilize insulin due to improved resistance against enzymatic disruption, with 60% and 80% of the insulin left after 4 h when incubated in simulated gastric and intestinal fluids, respectively, whereas non-encapsulated insulin is broken down completely at 0.5 h. Preservation of insulin bioactivity against preparative stresses is validated by intra-peritoneal injection of insulin after release from various liposomes using the surfactant Triton X-100. In a diabetic rat model chemically induced by streptozotocin, both thiamine- and niacin-decorated liposomes showed a comparable and sustained mild hypoglycemic effect. The superiority of decorated liposomes over conventional liposomes highlights the contribution of vitamin ligands. It is concluded that decoration of liposomes with thiamine or niacin facilitates interactions with gastrointestinal vitamin receptors and thereby facilitates oral absorption of insulin-loaded liposomes.

Abstract
For the development of an efficient intestinal delivery system for Porcine interferon-α (PoIFN-α), the understanding of transport mechanisms of which in the intestinal cell is essential. In this study, we investigated the absorption mechanisms of PoIFN-α in intestine cells. Caco-2 cells and fluorescein isothiocyanate-labeled (FITC)-PoIFN-α were used to explore the whole transport process, including endocytosis, intracellular trafficking, exocytosis, and transcytosis. Via various techniques, the transport pathways of PoIFN-α in Caco-2 cells and the mechanisms were clarified. Firstly, the endocytosis of PoIFN-α by Caco-2 cells was time, concentration and temperature dependence. And the lipid raft/caveolae endocytosis was the most likely endocytic pathway for PoIFN-α. Secondly, both Golgi apparatus and lysosome were involved in the intracellular trafficking of PoIFN-α. Thirdly, the treatment of indomethacin resulted in a significant decrease of exocytosis of PoIFN-α, indicating the participation of cyclooxygenase. Finally, to evaluate the efficiency of PoIFN-α transport, the transepithelial electrical resistance (TEER) value was measured to investigate the tight junctional integrity of the cell monolayers. The fluorescence microscope results revealed that the transport of PoIFN-α across the Caco-2 cell monolayers was restricted. In conclusion, this study depicts a probable picture of PoIFN-α transport in Caco-2 cells characterized by non-specificity, partial energy-dependency and low transcytosis.

Abstract
Co-delivery of microRNAs and chemotherapeutic drugs into tumor cells is an attractive strategy for synergetic breast cancer therapy due to their complementary mechanisms. In this work, a core-shell nanocarrier coated by cationic albumin was developed to simultaneously deliver miRNA-34a and docetaxel (DTX) into breast cancer cells for improved therapeutic effect. The co-delivery nanocarriers showed a spherical morphology with an average particle size of 183.9 nm, and they efficiently protected miRNA-34a from degradation by RNase and serum. Importantly, the nanocarriers entered the cytosol via a caveolae-mediated pathway without entrapment in endosomes/lysosomes, thus improving the utilization of the cargo. In vitro, the co-delivery nanocarriers suppressed the expression of anti-apoptosis gene Bcl-2 at both transcription and protein levels, inhibited tumor cell migration and efficiently induced cell apoptosis and cytotoxicity. In vivo, the co-delivery nanocarriers prolonged the blood circulation of DTX, enhanced tumor accumulation of the cargo and significantly inhibited tumor growth and metastasis in 4T1-tumor bearing mice models. Taken together, the present nanocarrier co-loading with DTX and miRNA-34a is a new nanoplatform for the combination of insoluble drugs and gene/protein drugs and provides a promising strategy for the treatment of metastatic breast cancer.

[PMID: 27117710 DOI: 10.1016/j.addr.2016.04.014] [Citation(s) in RCA: 83] [Impact Index Per Article: 10.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/16/2015] [Revised: 03/27/2016] [Accepted: 04/16/2016] [Indexed: 01/02/2023]
Abstract
Unraveling the mechanisms of nanoparticle transport across the intestinal barrier is essential for designing more efficient nanoparticles for oral administration. The physicochemical parameters of the nanoparticles (e.g., size, surface charge, chemical composition) dictate nanoparticle fate across the intestinal barrier. This review aims to address the most important findings regarding polymeric and lipidic nanoparticle transport across the intestinal barrier, including the evaluation of critical physicochemical parameters of nanoparticles that affect nanocarrier interactions with the intestinal barrier.

Abstract
The oral route is a preferred method of drug administration, though achieving effective drug delivery and minimizing off-target side effects is often challenging. Formulation into nanoparticles can improve drug stability in the harsh gastrointestinal (GI) tract environment, providing opportunities for targeting specific sites in the GI tract, increasing drug solubility and bioavailability, and providing sustained release in the GI tract. However, the unique and diverse physiology throughout the GI tract, including wide variation in pH, mucus that varies in thickness and structure, numerous cell types, and various physiological functions are both a barrier to effective delivery and an opportunity for nanoparticle design. Here, nanoparticle design aspects to improve delivery to particular sites in the GI tract are discussed. We then review new methods for evaluating oral nanoparticle formulations, including a short commentary on data interpretation and translation. Finally, the state-of-the-art in preclinical targeted nanoparticle design is reviewed.
