Abstract
Triple negative breast cancer (TNBC) is the most aggressive breast cancer subtype. Currently, no targeted treatment is available for TNBC, and the most common clinical therapy is tumor resection, which often promotes metastasis risks. Strong evidence suggests that the lymphatic metastasis is mediated by the C-C chemokine receptor type 7 (CCR7)/C-C motif chemokine ligand 21 crosstalk between tumor cells and the lymphatic system. It is hypothesized that CCR7 is a key immune modulator in the tumor microenvironment and the local blockade of CCR7 could effectively inhibit TNBC lymphatic metastasis. Accordingly, a plasmid encoding an antagonistic CCR7 affinity protein-CCR7 trap is delivered by tumor targeting nanoparticles in a highly metastatic 4T1 TNBC mouse model. Results show that CCR7 traps are transiently expressed, locally disrupt the signaling pathways in the tumor site, and efficiently inhibit TNBC lymphatic metastasis, without inducing immunosuppression as observed in systemic therapies using CCR7 monoclonal antibody. Significantly, upon applying CCR7 trap therapy prior to tumor resection, a 4T1 TNBC mouse model shows good prognosis without any further metastasis and relapse. In addition, CCR7 trap therapy efficiently inhibits the lymphatic metastasis in a B16F10 melanoma mouse model, indicating its great potential for various metastatic diseases treatment.

Abstract
Owing to the complex and still not fully understood physiological environment, the development of traditional nanosized drug delivery systems is very challenging for precision cancer therapy. It is very difficult to control the in vivo distribution of nanoparticles after intravenous injection. The ideal drug nanocarriers should not only have stealth surface for prolonged circulation time but also possess enhanced cellular internalization in tumor sites. Unfortunately, the stealth surface and enhanced cellular uptake seem contradictory to each other. How to integrate the two opposite aspects into one system is a very herculean but meaningful task. As an alternative drug delivery strategy, chameleon-like drug delivery systems were developed to achieve long circulation time while maintaining enhanced cancer cell uptake. Such drug nanocarriers can "turn off" their internalization ability during circulation. However, the enhanced cellular uptake can be readily activated upon arriving at tumor tissues. In this way, stealth surface and enhanced uptake are of dialectical unity in drug delivery. In this review, we focus on the surface engineering of drug nanocarriers to obtain simultaneous stealth surfaces in circulation and enhanced uptake in tumors. The current strategies and ongoing developments, including programmed tumor-targeting strategies and some specific zwitterionic surfaces, will be discussed in detail.

Abstract
The exploitation of gas therapy platforms holds great promise as a "green" approach for selective cancer therapy, however, it is often associated with some challenges, such as uncontrolled or insufficient gas generation and unclear therapeutic mechanisms. In this work, a gas therapy approach based on near-infrared (NIR) light-triggered sulfur dioxide (SO2) generation was developed, and the therapeutic mechanism as well as in vivo antitumor therapeutic efficacy was demonstrated. A SO2 prodrug-loaded rattle-structured upconversion@silica nanoparticles (RUCSNs) was constructed to enable high loading capacity without obvious leakage and to convert NIR light into ultraviolet light so as to activate the prodrug for SO2 generation. In addition, SO2 prodrug-loaded RUCSNs showed high cell uptake, good biocompatibility, intracellular tracking ability, and high NIR light-triggered cytotoxicity. Furthermore, the cytotoxic SO2 was found to induce cell apoptosis accompanied by the increase of intracellular reactive oxygen species levels and the damage of nuclear DNA. Moreover, efficient inhibition of tumor growth was achieved, associated with significantly prolonged survival of mice. Such NIR light-triggered SO2 therapy may provide an effective strategy to stimulate further development of synergistic cancer therapy platforms.

Abstract
Introduction Nanoparticles (NPs) are used in numerous products in technical fields and biomedicine; their potential adverse effects have to be considered in order to achieve safe applications. Besides their distribution in tissues, organs, and cellular localization, their impact and penetration during the process of tissue formation occurring in vivo during liver regeneration are critical steps for establishment of safe nanomaterials. Materials and methods In this study, 3D cell culture of human hepatocarcinoma cells (HepG2) was used to generate cellular spheroids, serving as in vitro liver microtissues. In order to determine their differential distribution and penetration depth in HepG2 spheroids, SiO2 NPs were applied either during or after spheroid formation. The NP penetration was comprehensively studied using confocal laser scanning microscopy and scanning electron microscopy. Results Spheroids were exposed to 100 µg mL−1 SiO2 NPs either at the beginning of spheroid formation, or during or after formation of spheroids. Microscopy analyses revealed that NP penetration into the spheroid is limited. During and after spheroid formation, SiO2 NPs penetrated about 20 µm into the spheroids, corresponding to about three cell layers. In contrast, because of the addition of SiO2 NPs simultaneously to cell seeding, NP agglomerates were located also in the spheroid center. Application of SiO2 NPs during the process of spheroid formation had no impact on final spheroid size. Conclusion Understanding the distribution of NPs in tissues is essential for biomedical applications. The obtained results indicate that NPs show only limited penetration into already formed tissue, which is probably caused by the alteration of the tissue structure and cell packing density during the process of spheroid formation.

Abstract
Melphalan is an efficient chemotherapeutic agent that is currently used to treat retinoblastoma (Rb); however, the inherent risk of immunogenicity and the hazardous integration of this drug in healthy cells is inevitable. MicroRNAs are short non-coding single-stranded RNAs that affect a vast range of biological processes. Previously, we focused on the regulatory role of miR-181a during cancer development and progression. In this manuscript, 171 nm switchable lipid nanoparticles (LNP) co-delivered melphalan and miR-181a with encapsulation efficiencies of 93%. Encapsulation of melphalan in LNP significantly improved its therapeutic efficiency. Gene analysis shows that miR-181a decreases the expression of anti-proliferative gene MAPK1 and anti-apoptotic gene Bcl-2, but significantly increased the expression of pro-apoptotic gene BAX. Our results suggest that the two agents have a complementary effect in reducing the viability of cultured Rb cells (primary and cell line) and decreasing Rb cell counts in an in-vivo xenograft Rb model in rats. Our results suggest that the proposed co-delivery technique significantly increases the therapeutic impact, allows for lower administration of melphalan, and consequently, could minimize the cytotoxic side-effects of this drug.

Abstract
Recently, nanoparticles have attracted much attention as new scaffolds for hemoglobin-based oxygen carriers (HBOCs). Indeed, the development of bionanotechnology paves the way for the rational design of blood substitutes, providing that the interaction between the nanoparticles and hemoglobin at a molecular scale and its effect on the oxygenation properties of hemoglobin are finely controlled. Here, we show that human hemoglobin has a high affinity for silica nanoparticles, leading to the adsorption of hemoglobin tetramers on the surface. The adsorption process results in a remarkable retaining of the oxygenation properties of human adult hemoglobin and sickle cell hemoglobin, associated with an increase of the oxygen affinity. The cooperative oxygen binding exhibited by adsorbed hemoglobin and the comparison with the oxygenation properties of diaspirin cross-linked hemoglobin confirmed the preservation of the tetrameric structure of hemoglobin loaded on silica nanoparticles. Our results show that silica nanoparticles can act as an effector for human native and mutant hemoglobin. Manipulating hemoglobin oxygenation using nanoparticles opens the way to the design of novel HBOCs.

Abstract
Antisense oligonucleotides (ASOs) are chemically synthesized nucleic acid analogs designed to bind to RNA by Watson-Crick base pairing. Following binding to the targeted RNA, the ASO perturbs RNA function by promoting selective degradation of the targeted RNA, altering RNA intermediary metabolism, or disrupting function of the RNA. Most antisense drugs are chemically modified to enhance their pharmacological properties and for passive targeting of the tissues of therapeutic interest. Recent advances in selective tissue targeting have resulted in a newer generation of ASO drugs that are more potent and better tolerated than previous generations, spawning renewed interest in identifying selective ligands that enhance targeted delivery of ASOs to tissues.

Abstract
Delivery of particle-based theranostic agents via their transportation on the surfaces of red blood cells, commonly referred to as RBC-hitchhiking, has historically been developed as a promising strategy for increasing the extremely poor blood circulation lifetime, primarily, of the large-sized sub-micron agents. Here, we show for the first time that RBC-hitchhiking can be extremely efficient for nanoparticle delivery and tumor treatment even in those cases when no circulation prolongation is observed. Specifically, we demonstrate that RBC-hitchhiking of certain small 100 nm particles, unlike that of the conventional sub-micron ones, can boost the delivery of non-targeted particles to lungs up to a record high value of 120-fold (and up to 40% of the injected dose). To achieve this remarkable result, we screened sub-200 nm nanoparticles of different sizes, polymer coatings and ζ-potentials and identified particles with the optimal RBC adsorption/desorption behavior. Furthermore, we demonstrated that such RBC-mediated rerouting of particles to lungs can be used to fight pulmonary metastases of aggressive melanoma B16-F1. Our findings could change the general paradigm of drug delivery for cancer treatment with RBC-hitchhiking. It is not the blood circulation lifetime that is the key factor for nanoparticle efficiency, but rather the complexation of nanoparticles with the RBC. The demonstrated technology could become a valuable tool for development of new strategies based on small nanoparticles for the treatment of aggressive and small-cell types of cancer as well as other lung diseases.

Abstract
Ultrasmall metal nanoparticles (NPs) are next-generation nano-based platforms for in vivo disease diagnosis and treatment. Due to their small size below the kidney filtration threshold and marked resistance to nonspecific serum protein adsorption, ultrasmall NPs can be rapidly excreted through the kidneys and escape liver uptake. However, although ultrasmall particles may be deemed highly resistant to protein adsorption, the real extent of this resistance is not known. Here, a simple compartmental model simulation was therefore implemented to understand how NP behavior in vivo could be modulated by soft, transient NP–plasma protein interactions characterized by dissociation constants in the millimolar range. In Model 1, ultrasmall NPs functionalized with a targeting probe, plasma proteins and target receptors were assumed to co-exist within a single compartment. Simulations were performed to understand the synergistic effect of soft interactions, systemic clearance and NP size on receptor occupancy in the single compartment. The results revealed the existence of a narrow range of ultraweak affinities and optimal particle sizes leading to greater target occupancy. In Model 2, simulations were performed to understand the impact of soft interactions on NP accumulation into a peripheral (tumor) compartment. The results revealed that soft interactions – but not active targeting – enhanced tumor uptake levels when tumor accumulation was limited by ‘fast’ plasma clearance and ‘slow’ vascular extravasation. The simple model presented here provides a basic framework to quantitatively understand the blood and tumor pharmacokinetics of ultrasmall NPs under the influence of transient protein interactions. A compartmental model simulation shows that the blood and tumor pharmacokinetics of ultrasmall metal nanoparticles can be modulated by soft interactions with plasma proteins.![]()

Abstract
The development of probes for biomolecular imaging and diagnostics is a very active research area. Among the different imaging modalities, optics emerged since it is a noninvasive and cheap imaging technique allowing real time imaging. In vitro, this technique is very useful however in vivo, fluorescence suffers from low signal-to-noise ratio due to tissue autofluorescence under constant excitation. To address this limitation, novel types of optical nanoprobes are actually being developed and among them, persistent luminescence nanoparticles (PLNPs), with long lasting near-infrared (NIR) luminescence capability, allows doing optical imaging without constant excitation and so without autofluorescence. This review will begin by introducing the physical phenomenon associated to the long luminescence decay of such nanoprobes, from minutes to hours after ceasing the excitation. Then we will show how this property can be used to develop in vivo imaging probes and also more recently nanotheranostic agents. Finally, preliminary data on their biocompatibility will be mentioned and we will conclude by envisioning on the future applications and improvements of such nanomaterials.

Abstract
Bone marrow endothelial cells (BMECs) regulate their microenvironment, which includes hematopoietic stem cells. This makes BMECs an important target cell type for siRNA or gene editing (e.g., CRISPR) therapies. However, siRNA and sgRNA have not been delivered to BMECs using systemically administered nanoparticles. Given that in vitro nanoparticle screens have not identified nanoparticles with BMEC tropism, we developed a system to quantify how >100 different nanoparticles deliver siRNA in a single mouse. This is the first barcoding system capable of quantifying functional cytosolic siRNA delivery (where the siRNA drug is active), distinguishing it from in vivo screens that quantify biodistribution (where the siRNA drug went). Combining this approach with bioinformatics, we performed in vivo directed evolution, and identified BM1, a lipid nanoparticle (LNP) that delivers siRNA and sgRNA to BMECs. Interestingly, chemical analysis revealed BMEC tropism was not related to LNP size; tropism changed with the structure of poly(ethylene glycol), as well as the presence of cholesterol. These results suggest that significant changes to vascular targeting can be imparted to a LNP by making simple changes to its chemical composition, rather than using active targeting ligands. BM1 is the first nanoparticle to efficiently deliver siRNA and sgRNA to BMECs in vivo, demonstrating that this functional in vivo screen can identify nanoparticles with novel tropism in vivo. More generally, in vivo screening may help reveal the complex relationship between nanoparticle structure and tropism, thereby helping scientists understand how simple chemical changes control nanoparticle targeting.

Abstract
Nanoparticles are often targeted to receptors expressed on specific cells, but few receptors are (i) highly expressed on one cell type and (ii) involved in endocytosis. One unexplored alternative is manipulating an endocytic gene expressed on multiple cell types; an ideal gene would inhibit delivery to cell type A more than cell type B, promoting delivery to cell type B. This would require a commonly expressed endocytic gene to alter nanoparticle delivery in a cell type-dependent manner in vivo; whether this can occur is unknown. Based on its microenvironmental regulation, we hypothesized Caveolin 1 (Cav1) would exert cell type-specific effects on nanoparticle delivery. Fluorescence was not sensitive enough to investigate this question, and as a result, we designed a platform named QUANT to study nanoparticle biodistribution. QUANT is 108× more sensitive than fluorescence and can be multiplexed. By measuring how 226 lipid nanoparticles (LNPs) delivered nucleic acids to multiple cell types in vivo in wild-type and Cav1 knockout mice, we found Cav1 altered delivery in a cell-type specific manner. Cav1 knockout did not alter LNP delivery to lung and kidney macrophages but substantially reduced LNP delivery to Kupffer cells, which are liver-resident macrophages. These data suggest caveolin-mediated endocytosis of nanomedicines by macrophages varies with tissue type. These results suggest manipulating receptors expressed on multiple cell types can tune drug delivery.

Abstract
In glioblastoma, the benefit from temozolomide chemotherapy is largely limited to a subgroup of patients (30-35%) with tumors exhibiting methylation of the promoter region of the O6-methylguanine-DNA methyltransferase (MGMT) gene. In order to allow more patients to benefit from this treatment, we explored magnetic resonance image-guided microbubble-enhanced low-intensity pulsed focused ultrasound (LIFU) to transiently open the blood-brain barrier and deliver a first-in-class liposome-loaded small molecule MGMT inactivator in mice bearing temozolomide-resistant gliomas. We demonstrate that a liposomal O6-(4-bromothenyl)guanine (O6BTG) derivative can efficiently target MGMT, thereby sensitizing murine and human glioma cells to temozolomide in vitro. Furthermore, we report that image-guided LIFU mediates the delivery of the stable liposomal MGMT inactivator in the tumor region resulting in potent MGMT depletion in vivo. Treatment with this new liposomal MGMT inactivator facilitated by LIFU-mediated blood-brain barrier opening reduced tumor growth and significantly prolonged survival of glioma-bearing mice, when combined with temozolomide chemotherapy. Exploring this novel combined approach in the clinic to treat glioblastoma patients with MGMT promoter-unmethylated tumors is warranted.

Abstract
Liver fibrosis is a condition of sustained wound healing in response to chronic liver injury caused by various factors such as viral, cholestatic and inflammatory diseases. Despite significant advances in the understanding of the mechanistic details of fibrosis, therapeutic intervention with the use of anti-fibrotic drugs achieved only marginal efficacy. Among which, pharmacokinetics profile of agents leading to off-targeting and suboptimal distribution are the principal limiting factors. Concurrently, inorganic nanoparticles (NPs) have gained significant recognition in biomedicine, owning to their unique physicochemical properties. Since NPs are known to accumulate in well vascularised organs, the intuitive therapeutic targeting of the liver using engineered NPs seems to be a plausible approach in treating liver fibrosis. However, the application of inorganic NPs also raised concerns of its potential long-term impact to humans. Current literatures have reported both negative risks as well as surprising benefits, thus sparking off a needful discussion about the feasibility of using inorganic NPs in treating liver fibrosis. Inorganic NPs entrapped in the liver may pose health risks, particularly due to their non-biodegradability and potential toxicity when accumulated in undesirable concentrations. This highlighted the need to assess the health risk of using inorganic NPs, and also to establish a framework to evaluate the conditions when the beneficial effects of these NPs would outweigh potential risks. Hence, this review takes a balanced approach on assessing the mechanistic details behind inorganic NP-induced biochemical perturbations, which could either alleviate or worsen liver fibrosis. Consequently, it attempts to chart out possibilities for future directions through optimizing therapeutic outcomes by design.

Abstract
Several in vitro studies have convincingly demonstrated that SiO2NPs mediated cytotoxicity, which was dose-, time- and size-dependent. The data on in vivo toxicity of SiO2NPs are even more contradictory. In the present study, we investigated the effects of sub-acute exposure to SiO2-NPs on spatial learning and memory, the biochemical parameters and the histology of organs. Rats were injected intravenously with a single dose of SiO2-NPs (20 mg/kg) during five consecutive days. The analysis of spatial memory in the Morris water maze showed that SiO2-NPs disrupt the cognitive abilities of rats. Moreover, SiO2-NPs could changes the blood counts. However, biochemical markers remained unchanged. Histological examination showed that SiO2-NPs induced pathological changes in rat organs. In this finding NPs were shown to cause granuloma formation and inflammatory cells infiltration in the liver.

Abstract
Introduction Siliceous nanoparticles (NPs) have been extensively studied in nanomedicine due to their high biocompatibility and immense biomedical potential. Although numerous technologies have been developed, the synthesis of siliceous NPs for biomedical applications mainly relies on a few core technologies predominantly intended to produce spherical-shaped NPs. Methods In this context, the impact of different morphologies of siliceous NPs on biodistribution in vivo is limited. In the present study, we developed a novel technique based on an aerosol silane reactor to produce sintered silicon NPs of similar size but different surface areas due to distinct spherical subunits. Silica-converted particles were functionalized for radiolabeling with copper-64 (64Cu) to systematically analyze their behavior in the passive targeting of A431 tumor xenografts in mice after intravenous injection. Results While low nonspecific uptake was observed in most organs, the majority of particles were accumulated in the liver, spleen, and lung. Depending on the morphologies and function-alization, significant differences in the uptake profiles of the particles were observed. In terms of tumor uptake, spherical shapes with lower surface areas showed the highest accumulation and tumor-to-blood ratios of all investigated particles. Conclusion This study highlights the importance of shape and fuctionalization of siliceous NPs on organ and tumor accumulation as significant factors for biomedical applications.

Abstract
The progress of nanoparticle (NP)-based drug delivery has been hindered by an inability to establish structure-activity relationships in vivo. Here, using stable, monosized, radiolabeled, mesoporous silica nanoparticles (MSNs), we apply an integrated SPECT/CT imaging and mathematical modeling approach to understand the combined effects of MSN size, surface chemistry and routes of administration on biodistribution and clearance kinetics in healthy rats. We show that increased particle size from ~32- to ~142-nm results in a monotonic decrease in systemic bioavailability, irrespective of route of administration, with corresponding accumulation in liver and spleen. Cationic MSNs with surface exposed amines (PEI) have reduced circulation, compared to MSNs of identical size and charge but with shielded amines (QA), due to rapid sequestration into liver and spleen. However, QA show greater total excretion than PEI and their size-matched neutral counterparts (TMS). Overall, we provide important predictive functional correlations to support the rational design of nanomedicines. Nanoparticle applications are limited by insufficient understanding of physiochemical properties on in vivo disposition. Here, the authors explore the influence of size, surface chemistry and administration on the biodisposition of mesoporous silica nanoparticles using image-based pharmacokinetics.

Abstract
Nanoparticles are frequently designed to improve the pharmacokinetics profiles and tissue distribution of small molecules to prolong their systemic circulation, target specific tissue, or widen the therapeutic window. The multifunctionality of nanoparticles is frequently presented as an advantage but also results in distinct and complicated in vivo disposition properties compared with a conventional formulation of the same molecules. Physiologically based pharmacokinetic (PBPK) modeling has been a useful tool in characterizing and predicting the systemic disposition, target exposure, and efficacy and toxicity of various types of drugs when coupled with pharmacodynamic modeling. Here we review the unique disposition characteristics of nanoparticles, assess how PBPK modeling takes into account the unique disposition properties of nanoparticles, and comment on the applications and challenges of PBPK modeling in characterizing and predicting the disposition and biological effects of nanoparticles.

Abstract
Muscle atrophy occurs during chronic diseases, resulting in diminished quality of life and compromised treatment outcomes. There is a high demand for therapeutics that increase muscle mass while abrogating the need for special dietary and exercise requirements. Therefore, we developed an efficient nanomedicine approach capable of increasing muscle mass. Methods: The therapy is based on nanoparticle-mediated delivery of follistatin messenger RNA (mRNA) to the liver after subcutaneous administration. The delivered mRNA directs hepatic cellular machinery to produce follistatin, a glycoprotein that increases lean mass through inhibition of negative regulators of muscle mass (myostatin and activin A). These factors are elevated in numerous disease states, thereby providing a target for therapeutic intervention. Results: Animal studies validated that mRNA-loaded nanoparticles enter systemic circulation following subcutaneous injection, accumulate and internalize in the liver, where the mRNA is translated into follistatin. Follistatin serum levels were elevated for 72 h post injection and efficiently reduced activin A and myostatin serum concentrations. After eight weeks of repeated injections, the lean mass of mice in the treatment group was ~10% higher when compared to that of the controls. Conclusion: Based on the obtained results demonstrating an increased muscle mass as well as restricted fat accumulation, this nanoplatform might be a milestone in the development of mRNA technologies and the treatment of muscle wasting disorders.

Abstract
Dysfunctional endothelium causes more disease than any other cell type. Systemically administered RNA delivery to nonliver tissues remains challenging, in large part because there is no high-throughput method to identify nanoparticles that deliver functional mRNA to cells in vivo. Here we report a system capable of simultaneously quantifying how >100 lipid nanoparticles (LNPs) deliver mRNA that is translated into functional protein. Using this system (named FIND), we measured how >250 LNPs delivered mRNA to multiple cell types in vivo and identified 7C2 and 7C3, two LNPs that efficiently deliver siRNA, single-guide RNA (sgRNA), and mRNA to endothelial cells. The 7C3 delivered Cas9 mRNA and sgRNA to splenic endothelial cells as efficiently as hepatocytes, distinguishing it from LNPs that deliver Cas9 mRNA and sgRNA to hepatocytes more than other cell types. These data demonstrate that FIND can identify nanoparticles with novel tropisms in vivo.

Doxorubicin (DOX) is one of the anthracycline antibiotics but its clinical use is limited due to its severe cardiotoxicity. In this study, novel hybrid nanoparticles by self-assembling based on pectin-doxorubicin conjugates (PDC-NPs) were fabricated for HCC treatment. The stabilized structure of the PDC-NPs was characterized by methylene blue absorption, the size, zeta potential and the morphology, which was investigated by Zetasizer nanoparticle analyzer and transmission electron microscope (TEM), of nanoparticles. The PDC-NPs achieved a sustained and prolonged release ability, which was illustrated with in vitro drug release profiles, anti-cell proliferation study, cellular uptake assay and in vivo pharmacokinetics analysis. Biocompatibility of the PDC-NPs was assessed with bovine serum albumin (BSA) adsorption test, hemolysis activity examination and viability evaluation of human umbilical vein endothelial cells. Importantly, in vivo studies of the PDC-NPs, which were performed in the athymic BALB/c nude mice, demonstrated that the PDC-NPs significantly reduced the lethal side effect of DOX. Additionally, the H&E staining and serum biochemistry study further confirmed the excellent biological security of the PDC-NPs.

Ultrasmall targeted nanoparticles with engineered antibody fragments for imaging detection of HER2-overexpressing breast cancer. Nat Commun 2018; 9:4141. [PMID: 30297810 PMCID: PMC6175906 DOI: 10.1038/s41467-018-06271-5] [Citation(s) in RCA: 103] [Impact Index Per Article: 17.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/02/2018] [Accepted: 08/24/2018] [Indexed: 12/11/2022] Open
Abstract
Controlling the biodistribution of nanoparticles upon intravenous injection is the key to achieving target specificity. One of the impediments in nanoparticle-based tumor targeting is the inability to limit the trafficking of nanoparticles to liver and other organs leading to smaller accumulated amounts in tumor tissues, particularly via passive targeting. Here we overcome both these challenges by designing nanoparticles that combine the specificity of antibodies with favorable particle biodistribution profiles, while not exceeding the threshold for renal filtration as a combined vehicle. To that end, ultrasmall silica nanoparticles are functionalized with anti-human epidermal growth factor receptor 2 (HER2) single-chain variable fragments to exhibit high tumor-targeting efficiency and efficient renal clearance. This ultrasmall targeted nanotheranostics/nanotherapeutic platform has broad utility, both for imaging a variety of tumor tissues by suitably adopting the targeting fragment and as a potentially useful drug delivery vehicle.

Abstract
Gold nanoparticles (GNPs) have shown great promises in various biomedical applications. Although GNPs exhibit excellent therapeutic efficacy in in vitro and in vivo in numerous studies, there still exists significant biosafety concerns, mainly for their nonbiodegradability and tendency to be trapped in the liver and spleen. To tackle this problem, hexapeptides are utilized to modify the GNP surface to not only impart them with potent anti-inflammatory activity, but also facilitate their rapid clearance in vivo. Previously, a unique class of peptide-GNP hybrids that potently inhibit multiple TLR signaling pathways in macrophages was identified; in this work, it is further demonstrated that these hybrids, after intratracheal instillation, are capable of effectively reducing lung inflammation and injury by decreasing neutrophil infiltration and increasing the number of regulatory T cells in the lung in a lipopolysaccharide-induced acute lung injury (ALI) mouse model. More importantly, these hybrids can be effectively excreted 26 h post-administration with only 8.49 ± 0.70% of them remaining in the body, primarily in the lung and intestine and less than 0.03% accumulated in the liver and spleen. This work provides strong evidences that properly designed peptide-GNP hybrids can serve as the next generation of effective and safe anti-inflammatory nanotherapeutics to treat ALI.

Abstract
Introduction We hereby report on studies aimed to characterize safety, pharmacokinetics, and bio-distribution of fluorescent nanodiamond particles (NV)-Z~800 (FNDP-(NV)) administered to rats by intravenous infusion in a single high dose. Methods Broad scale biological variables were monitored following acute (90 minutes) and subacute (5 or 14 days) exposure to FNDP-(NV). Primary endpoints included morbidity and mortality, while secondary endpoints focused on hematology and clinical biochemistry biomarkers. Particle distribution (liver, spleen, lung, heart, and kidney) was assessed by whole organ near infrared imaging using an in vivo imaging system. This was validated by the quantification of particles extracted from the same organs and visualized by fluorescent and scanning electron microscopy. FNDP-(NV)-treated rats showed no change in morbidity or mortality and preserved normal motor and sensory function, as assessed by six different tests. Results Blood cell counts and plasma biochemistry remained normal. The particles were principally distributed in the liver and spleen. The liver particle load accounted for 51%, 24%, and 18% at 90 minutes, 5 days, and 14 days, respectively. A pilot study of particle clearance from blood indicated 50% clearance 33 minutes following the end of particle infusion. Conclusion We concluded that systemic exposure of rats to a single high dose of FDNP-(NV)-Z~800 (60 mg/kg) appeared to be safe and well tolerated over at least 2 weeks. These data suggest that FNDP-(NV) should proceed to preclinical development in the near future.

Abstract
Gene therapy through systemic administration is expected to offer significant therapeutic potential against intractable cancers, including pancreatic cancer. One of the requirements for in vivo gene therapy is the development of a gene carrier with a high level of safety, transfection ability and tumour accumulation. Bovine serum albumin (BSA)-poly(2-dimethylaminoethyl methacrylate) (PDMAEMA) conjugation (BSA-PDMAEMA conjugation) could result in the development of a promising gene carrier. This conjugate could preserve the BSA structure well and efficiently condense the nucleotide inside, resulting in the formation of BSA-PDMAEMA nanoparticles that have a polyion complex core and surrounding BSA corona with a size of <100 nm. The nanoparticles that were produced based on BSA-PDMAEMA conjugation possessed good characteristics for use as a gene carrier with good biocompatibility, appropriate blood retention and gene protective properties. Furthermore, the in vivo two-dimensional and three-dimensional biodistribution in a xenograft pancreatic cancer (AsPC-1) model in mice clearly showed that BSA-PDMAEMA nanoparticles accumulated at the tumour site via enhanced permeability and the retention effect. Furthermore, BSA-PDMAEMA nanoparticles, which condensed the active anti-cancer oligonucleotide, ISIS5132, inhibited the growth of cancer in AsPC-1-bearing mice compared to mice which were administered with ISIS5132 alone. The structure of the BSA-PDMAEMA nanoparticles, i.e. the polyion complex core with the BSA corona, would comprehensively contribute to these ideal characteristics for use as a gene carrier. In conclusion, BSA-PDMAEMA nanoparticles could exert a therapeutic effect on intractable pancreatic cancer in vivo, indicating their use as a promising gene carrier.

Abstract
Tumor-specific delivery of therapeutics is challenging. One of the major hurdles for successfully delivering targeted agents by nanovectors is the filtering role of the liver in rapidly sequestering nanovectors from the circulation. Exosomes, a type of endogenous nanoparticle, circulate continuously in the peripheral blood and play a role in intercellular communication. The aim of this study was to determine whether the level of endogenous exosomes has an effect on nanovector delivery efficiency of targeted agents. Methods: Exosomes were isolated from peripheral blood and intravenously (I.V.) injected into tumor-bearing mice. Subsequently, 1,1-dioctadecyl-3,3,3'3'-tetramethylindotricarbocyanine-iodide (DiR) fluorescent dye-labeled nanoparticles, including grapefruit nanovectors (GNV) and standard liposomes, were I.V. injected in the mice. The efficiency of redirecting GNVs from liver to other organs of injected mice was further analyzed with in vivo imaging. The concentration of chemo drugs delivered by GNV was measured by HPLC and the anti-lung metastasis therapeutic effects of chemo drugs delivered by GNVs in mouse breast cancer and melanoma cancer models were evaluated. Results: We show that tail vein-injected exosomes isolated from mouse peripheral blood were predominately taken up by liver Kupffer cells. Injection of peripheral blood-derived exosomes before I.V. injection of grapefruit-derived nanovector (GNV) decreased the deposition of GNV in the liver and redirected the GNV to the lung and to the tumor in breast and melanoma tumor-bearing mouse models. Enhanced therapeutic efficiency of doxorubicin (Dox) or paclitaxel (PTX) carried by GNVs for lung metastases was demonstrated when there was an I.V. injection of exosomes before therapeutic treatment. Furthermore, we found that CD36 and IGFR1 receptor-mediated pathways played a critical role in the exosome-mediated inhibitory effect of GNV entry into liver macrophages. Conclusions: Collectively, our findings provide a foundation for using autologous exosomes to enhance therapeutic vector targeted delivery to the lung.

Abstract
The encapsulation of mRNA in nanosystems as gene vaccines for immunotherapy purposes has experienced an exponential increase in recent years. Despite the many advantages envisaged within these approaches, their application in clinical treatments is still limited due to safety issues. These issues can be attributed, in part, to liver accumulation of most of the designed nanosystems and to the inability to transfect immune cells after an intravenous administration. In this context, this study takes advantage of the known versatile properties of the oligopeptide end-modified poly (β-amino esters) (OM-PBAEs) to complex mRNA and form discrete nanoparticles. Importantly, it is demonstrated that the selection of the appropriate end-oligopeptide modifications enables the specific targeting and major transfection of antigen-presenting cells (APC) in vivo, after intravenous administration, thus enabling their use for immunotherapy strategies. Therefore, with this study, it can be confirmed that OM-PBAE are appropriate systems for the design of mRNA-based immunotherapy approaches aimed to in vivo transfect APCs and trigger immune responses to fight either tumors or infectious diseases.

Abstract
The introduction of nanoparticle-mediated delivery and therapy has revolutionized cancer treatment approaches. However, there has been limited success in clinical trials because current approaches have not simultaneously satisfied therapeutic efficacy and biosafety criteria to an adequate degree. Here, we employ efficient macrophage-mediated exocytosis of elongated nanoparticles to facilitate their localization in tumor cells for cancer therapy and their transport to hepatocytes for hepatobiliary excretion. In vitro studies show that PEGylated high-aspect ratio gold nanoparticles exit macrophages more rapidly and remain in tumor cells longer, compared with low-aspect ratio and spherical nanoparticles. In tumors, high-aspect ratio nanoparticles tend to stay in tumor cells and escape from tumor-associated macrophages when they are taken up by those cells. In the liver, high-aspect ratio nanoparticles cleared by Kupffer cells mostly take the hepatobiliary excretion pathway through efficient Kupffer cell-hepatocyte transfer. Furthermore, we demonstrate that time-dependent localization of elongated gold nanoparticles toward tumor cells in tumor tissues enhances the overall phototherapeutic outcome. Engineering nanoparticles to modulate their exocytosis provides a new approach to improve cancer nanomedicine and pave the way toward clinical translation.

Abstract
AbstractResearch on engineered nanomaterials (ENM) has progressed rapidly from the very early stages of studying their unique, size-dependent physicochemical properties and commercial exploration to the development of products that influence our everyday lives. We have previously reviewed various methods for synthesis, surface functionalization, and analytical characterization of ENM in a publication titled ‘Engineered Nanomaterials: Preparation, Functionalization and Characterization’. In this second, inter-linked document, we first provide an overview of important applications of ENM in products relevant to human healthcare and consumer goods, such as food, textiles, and cosmetics. We then highlight the challenges for the design and development of new ENM for bio-applications, particularly in the rapidly developing nanomedicine sector. The second part of this document is dedicated to nanotoxicology studies of ENM in consumer products. We describe the various biological targets where toxicity may occur, summarize the four nanotoxicology principles, and discuss the need for careful consideration of the biodistribution, degradation, and elimination routes of nanosized materials before they can be safely used. Finally, we review expert opinions on the risk, regulation, and ethical aspects of using engineered nanomaterials in applications that may have direct or indirect impact on human health or our environment.

Abstract
Low toxic theranostic nanoparticles that can simultaneously achieve effective tumor accumulation and rapid renal clearance are highly desired for imaging contrast agents and photothermal therapy (PTT) in tumor diagnosis and therapy. Herein, we report a one-pot method for preparing multifunctional nanoparticles (FeAP-NPs) based on the coordination interaction of natural polyphenols (anthocyanins) extracted from fruits, FeIII ions, and poly(l-glutamic acid)- g-methoxy poly(ethylene glycol) copolymers. The FeAP-NPs possess the following favorable advantages: (1) The components of FeAP-NPs originate from natural products, an endogenous element, and poly(amino acid) derivatives, guaranteeing their safety for in vivo application. (2) FeAP-NPs exhibit excellent dual photoacoustic (PA)/magnetic resonance (MR) imaging capacity and high photothermal efficiency. (3) FeAP-NPs can overcome the intractable dilemma of the enhanced permeability and retention (EPR) effect and renal clearance for nanomedicine through the dynamic disassembling ability, which induces a switch of the elimination pathway. Complete tumor ablation is realized by PTT in MCF-7-bearing nude mice under the precise guide of PA and MR imaging. The detailed evaluation of the safety, biodistribution, and elimination behaviors of FeAP-NPs is conducted in vitro or in vivo. This work provides a promising comprehensive solution for nanomedicine clinical application.

Abstract
In recent years, quantum dots (QDs) have potential applications in technology, research and medicine. The small particle size is coupled to their unique chemical and physical properties and their excellent fluorescence characteristics. A growing number of studies have shown that QDs are distributed to secondary organs through multiple pathways, while the liver is the main reservoir of QDs. Here, we review current liver toxicity studies of QDs in vivo and in vitro. Mechanisms of hepatotoxicity are discussed and the problem of extrapolating knowledge gained from cell-based studies into animal studies is highlighted. In this context, there still exists significant discrepancies between in vitro and in vivo results, and the specific toxicity mechanism remains unclear. The hepatotoxicities of QDs are the need for a unifying protocol for reliable and realistic toxicity reports.

[PMID: 30096444 DOI: 10.1016/j.biomaterials.2018.08.013] [Citation(s) in RCA: 47] [Impact Index Per Article: 7.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/10/2018] [Revised: 07/21/2018] [Accepted: 08/03/2018] [Indexed: 12/20/2022]
Abstract
Vemurafenib is a chemotherapeutic drug recently approved by the FDA to treat melanoma. Because the drug is usually delivered orally, the route of administration readily causes damage to major organs with limited antitumor efficacy and bioavailability. In this study, we developed a peptide-modified vemurafenib-loaded liposome for the targeted inhibition of subcutaneous melanoma via the skin. First, the peptide-modified vemurafenib-loaded liposomes (Vem-TD-Lip) were prepared and characterized with respect to the size, shape and charge; the loading efficiency of vemurafenib; and the stability. Then, the intracellular uptake of these liposomes, their limited cytotoxicity, the selective inhibition of melanoma cells harboring BRAF mutations, and the liposome permeation ability were confirmed through in vitro experiments. Finally, the safety and antitumor activity of Vem-TD-Lip were evaluated in vivo. The results showed that transdermal delivery of Vem-TD-Lip effectively targeted and inhibited subcutaneous melanoma in male mice, the administration of Vem-TD-Lip through skin was better than that through oral administration and intravenous injection in terms of reducing damage to major organs and enhancing antitumor efficacy, and the peptide TD significantly enhanced the delivery of Vem-TD-Lip across the skin. This work provides a new strategy for delivering vemurafenib to target and inhibit subcutaneous melanoma.

ULTRASOUND IN MEDICINE & BIOLOGY 2018; 44:1836-1852.

Abstract
Phase-shift droplets can be converted by sound from low-echogenicity, liquid-core agents into highly echogenic microbubbles. Many proposed applications in imaging and therapy take advantage of the high spatiotemporal control over this dynamic transition. Although some studies have reported increased circulation time of the droplets compared with microbubbles, few have directly explored the impact of encapsulation on droplet performance. With the goal of developing nanoscale droplets with increased circulatory persistence, we first evaluate the half-life of several candidate phospholipid encapsulations in vitro at clinical frequencies. To evaluate in vivo circulatory persistence, we develop a technique to periodically measure droplet vaporization from high-frequency B-mode scans of a mouse kidney. Results show that longer acyl chain phospholipids can dramatically reduce droplet degradation, increasing median half-life in vitro to 25.6 min-a 50-fold increase over droplets formed from phospholipids commonly used for clinical microbubbles. In vivo, the best-performing droplet formulations showed a median half-life of 18.4 min, more than a 35-fold increase in circulatory half-life compared with microbubbles with the same encapsulation in vivo. These findings also point to possible refinements that may improve nanoscale phase-shift droplet performance beyond those measured here.

Abstract
Two clear windows in the near-infrared (NIR) spectrum are of considerable current interest for in vivo molecular imaging and spectroscopic detection. The main rationale is that near-infrared light can penetrate biological tissues such as skin and blood more efficiently than visible light because these tissues scatter and absorb less light at longer wavelengths. The first clear window, defined as light wavelengths between 650nm and 950nm, has been shown to be far superior for in vivo and intraoperative optical imaging than visible light. The second clear window, operating in the wavelength range of 1000-1700nm, has been reported to further improve detection sensitivity, spatial resolution, and tissue penetration because tissue photon scattering and background interference are further reduced at longer wavelengths. Here we discuss recent advances in developing biocompatible plasmonic nanoparticles for in vivo and intraoperative surface-enhanced Raman scattering (SERS) in both the first and second NIR windows. In particular, a new class of 'broad-band' plasmonic nanostructures is well suited for surface Raman enhancement across a broad range of wavelengths allowing a direct comparison of detection sensitivity and tissue penetration between the two NIR window. Also, optimized and encoded SERS nanoparticles are generally nontoxic and are much brighter than near-infrared quantum dots (QDs), raising new possibilities for ultrasensitive detection of microscopic tumors and image-guided precision surgery.

Abstract
As a bridge between individual atoms and large plasmonic nanoparticles, ultrasmall (core size <3 nm) noble metal nanoparticles (UNMNPs) have been serving as model for us to fundamentally understand many unique properties of noble metals that can only be observed at an extremely small size scale. With decades'efforts, many significant breakthroughs in the synthesis, characterization and functionalization of UNMNPs have laid down a solid foundation for their future applications in the healthcare. In this review, we aim to tightly correlate these breakthroughs with their biomedical applications and illustrate how to utilize these breakthroughs to address long-standing challenges in the clinical translation of nanomedicines. In the end, we offer our perspective on the remaining challenges and opportunities at the frontier of biomedical-related UNMNPs research.

Abstract
A nanoparticle system for systemic delivery of therapeutics is described, which incorporates a means of tracking the fate of the nanocarrier and its residual drug payload in vivo by photoluminescence (PL). Porous silicon nanoparticles (PSiNPs) containing the proapoptotic antimicrobial peptide payload, D [KLAKLAK]2 , are monitored by measurement of the intrinsic PL intensity and the PL lifetime of the nanoparticles. The PL lifetime of the PSiNPs is on the order of microseconds, substantially longer than the nanosecond lifetimes typically exhibited by conventional fluorescent tags or by autofluorescence from cells and tissues; thus, emission from the nanoparticles is readily discerned in the time-resolved PL spectrum. It is found that the luminescence lifetime of the PSiNP host decreases as the nanoparticle dissolves in phosphate-buffered saline solution (37 °C), and this correlates with the extent of release of the peptide payload. The time-resolved PL measurement allows tracking of the in vivo fate of PSiNPs injected (via tail vein) into mice. Clearance of the nanoparticles through the liver, kidneys, and lungs of the animals is observed. The luminescence lifetime of the PSiNPs decreases with increasing residence time in the mice, providing a measure of half-life for degradation of the drug nanocarriers.

Abstract
The field of nanotechnology has grown exponentially during the last few decades, due in part to the use of nanoparticles in many manufacturing processes, as well as their potential as clinical agents for treatment of diseases and for drug delivery. This has created several new avenues by which humans can be exposed to nanoparticles. Unfortunately, investigations assessing the toxicological impacts of nanoparticles (i.e. nanotoxicity), as well as their possible risks to human health and the environment, have not kept pace with the rapid rise in their use. This has created a gap-in-knowledge and a substantial need for more research. Studies are needed to help complete our understanding of the mechanisms of toxicity of nanoparticles, as well as the mechanisms mediating their distribution and accumulation in cells and tissues and their elimination from the body. This review summarizes our knowledge on nanoparticles, including their various applications, routes of exposure, their potential toxicity and risks to human health.

Impact of mucoadhesive polymeric nanoparticulate systems on oral bioavailability of a macromolecular model drug. Eur J Pharm Biopharm 2018; 130:281-289.

Abstract
Nanoparticles (NP) only different in mucoadhesivity are compared for impact on drug oral bioavailability. Two polymeric NP types based on quaternary ammonium-chitosan (NP QA-Ch) and S-protected thiolated derivative thereof (NP QA-Ch-S-pro), respectively, containing the macromolecular drug model, FD4, were prepared by crosslinking each polymer with reduced MW hyaluronic acid. The structure of basic polymers was determined by H1NMR analysis. NP were similar in size (371 ± 38 vs. 376 ± 82 nm); polydispersity index (0.39 ± 0.08 vs. 0.41 ± 0.10); zeta potential (13.4 ± 0.9 vs. 11.9 ± 1.2 mV); reversible interactions with drug (bound drug, 67 vs. 66%); encapsulation efficiency (23 ± 5 vs. 23 ± 8%); release properties (15% released in 15 h in both cases); and apparent permeation across excised rat intestine (Papp, 8.8 ± 0.8 vs. 10 ± 1 cm/s). Then the differences in NP transport ratio through mucus (TR, 0.75 vs. 0.37) and adhesion to excised rat intestinal mucosa (adsorbed fraction, 23 ± 3 vs. 45 ± 2%) were ascribed to higher mucoadhesivity of NP QA-Ch-S-pro compared to NP QA-Ch. This directly influenced drug oral bioavailability in rats (Tmax, 1 vs. 2 h; AUC, 1.7 ± 0.3 vs. 2.9 ± 0.4 μg/mL min, for NP QA-Ch and NP QA-Ch-S-pro, respectively). Mucoadhesivity increases drug bioavailability by retaining NP at its absorption site and opposing its transit down the GI tract. Data on drug accumulation in rat liver allows the assertion that NP is absorbed by transcytosis across intestinal epithelium and transported from blood into liver by Kuppfer cells.
