Abstract
Multiple vaccine platforms have been employed to develop the nasal SARS-CoV-2 vaccines in preclinical studies, and the dominating pipelines are viral vectored as protein-based vaccines. Among them, several viral vectored-based vaccines have entered clinical development. Nevertheless, some unsatisfactory results were reported in these clinical studies. In the face of such urgent situations, it is imperative to rapidly develop the next-generation intranasal COVID-19 vaccine utilizing other technologies. Nanobased intranasal vaccines have emerged as an approach against respiratory infectious diseases. Harnessing the power of nanotechnology, these vaccines offer a noninvasive yet potent defense against pathogens, including the threat of COVID-19. The improvements made in vaccine mucosal delivery technologies based on nanoparticles, such as lipid nanoparticles, polymeric nanoparticles, inorganic nanoparticles etc., not only provide stability and controlled release but also enhance mucosal adhesion, effectively overcoming the limitations of conventional vaccines. Hence, in this review, we overview the evaluation of intranasal vaccine and highlight the current barriers. Next, the modern delivery systems based on nanoplatforms are summarized. The challenges in clinical application of nanoplatform based intranasal vaccine are finally discussed.

Nanomedicine, as an interdisciplinary discipline involving the development and application of nanoscale materials and technologies, is rapidly developing under the impetus of bionanotechnology and has attracted a great deal of attention from researchers. Especially, with the global outbreak of COVID-19, the in-depth investigation of the infection mechanism of the viruses has made the study of virus-mimicking nanosystems (VMNs) a popular research topic. In this review, we initiate with a brief historical perspective on the emergence and development of VMNs for providing a comprehensive view of the field. Next, we present emerging design principles and functionalization strategies for fabricating VMNs in light of viral infection mechanisms. Then, we describe recent advances in VMNs in biology, with a major emphasis on representative examples. Finally, we summarize the opportunities and challenges that exist in this field, hoping to provide new insights and inspiration to develop VMNs for disease diagnosis and treatment and to attract the interest of more researchers from different fields.

Abstract
Numerous neurodegenerative conditions, such as Alzheimer's, Huntington's, Parkinson's, amyotrophic lateral sclerosis, and glioblastoma multiform are now becoming significant concerns of global health. Formulation-related issues, physiological and anatomical barriers, post-administration obstacles, physical challenges, regulatory limitations, environmental hurdles, and health and safety issues have all hindered successful delivery and effective outcomes despite a variety of treatment options. In the current review, we covered the intranasal route, an alternative strategic route targeting brain for improved delivery across the BBB. The trans-nasal pathway is non-invasive, directing therapeutics directly towards brain, circumventing the barrier and reducing peripheral exposure. The delivery of nanosized vesicles loaded with drugs was also covered in the review. Nanovesicle systems are organised in concentric bilayered lipid membranes separated with aqueous layers. These carriers surmount the disadvantages posed by intranasal delivery of rapid mucociliary clearance and enzymatic degradation, and enhance retention of drug to reach the site of target. In conclusion, the review covers in-depth conclusions on numerous aspects of formulation of drug-loaded vesicular system delivery across BBB, current marketed nasal devices, significant jeopardies, potential therapeutic aids, and current advancements followed by future perspectives.

Abstract
The advent of immunotherapy has revolutionized the treating modalities of cancer. Cancer vaccine, aiming to harness the host immune system to induce a tumor-specific killing effect, holds great promises for its broad patient coverage, high safety, and combination potentials. Despite promising, the clinical translation of cancer vaccines faces obstacles including the lack of potency, limited options of tumor antigens and adjuvants, and immunosuppressive tumor microenvironment. Biomimetic and bioinspired nanotechnology provides new impetus for the designing concepts of cancer vaccines. Through mimicking the stealth coating, pathogen recognition pattern, tissue tropism of pathogen, and other irreplaceable properties from nature, biomimetic and bioinspired cancer vaccines could gain functions such as longstanding, targeting, self-adjuvanting, and on-demand cargo release. The specific behavior and endogenous molecules of each type of living entity (cell or microorganism) offer unique features to cancer vaccines to address specific needs for immunotherapy. In this review, the strategies inspired by eukaryotic cells, bacteria, and viruses will be overviewed for advancing cancer vaccine development. Our insights into the future cancer vaccine development will be shared at the end for expediting the clinical translation.

Abstract
Gene therapy is an innovative approach in the field of regenerative medicine. This therapy entails the transfer of genetic material into a patient's cells to treat diseases. In particular, gene therapy for neurological diseases has recently achieved significant progress, with numerous studies investigating the use of adeno-associated viruses for the targeted delivery of therapeutic genetic fragments. This approach has potential applications for treating incurable diseases, including paralysis and motor impairment caused by spinal cord injury and Parkinson's disease, and it is characterized by dopaminergic neuron degeneration. Recently, several studies have explored the potential of direct lineage reprogramming (DLR) for treating incurable diseases, and highlighted the advantages of DLR over conventional stem cell therapy. However, application of DLR technology in clinical practice is hindered by its low efficiency compared with cell therapy using stem cell differentiation. To overcome this limitation, researchers have explored various strategies such as the efficiency of DLR. In this study, we focused on innovative strategies, including the use of a nanoporous particle-based gene delivery system to improve the reprogramming efficiency of DLR-induced neurons. We believe that discussing these approaches can facilitate the development of more effective gene therapies for neurological disorders.

Abstract
Nanobiotechnology, as a novel and more specialized branch of science, has provided a number of nanostructures such as nanoparticles, by utilizing the methods, techniques, and protocols of other branches of science. Due to the unique features and physiobiological characteristics, these nanostructures or nanocarriers have provided vast methods and therapeutic techniques, against microbial infections and cancers and for tissue regeneration, tissue engineering, and immunotherapies, and for gene therapies, through drug delivery systems. However, reduced carrying capacity, abrupt and non-targeted delivery, and solubility of therapeutic agents, can affect the therapeutic applications of these biotechnological products. In this article, we explored and discussed the prominent nanobiotechnological methods and products such as nanocarriers, highlighted the features and challenges associated with these products, and attempted to conclude if available nanostructures offer any scope of improvement or enhancement. We aimed to identify and emphasize the nanobiotechnological methods and products, with greater prospect and capacity for therapeutic improvements and enhancements. We found that novel nanocarriers and nanostructures, such as nanocomposites, micelles, hydrogels, microneedles, and artificial cells, can address the associated challenges and inherited drawbacks, with help of conjugations, sustained and stimuli-responsive release, ligand binding, and targeted delivery. We recommend that nanobiotechnology, despite having few challenges and drawbacks, offers immense opportunities that can be harnessed in delivering quality therapeutics with precision and prediction. We also recommend that, by exploring the branched domains more rigorously, bottlenecks and obstacles can also be addressed and resolved in return.

Abstract
RNA therapy is a disruptive technology comprising a rapidly expanding category of drugs. Further translation of RNA therapies to the clinic will improve the treatment of many diseases and help enable personalized medicine. However, in vivo delivery of RNA remains challenging due to the lack of appropriate delivery tools. Current state-of-the-art carriers such as ionizable lipid nanoparticles still face significant challenges, including frequent localization to clearance-associated organs and limited (1-2%) endosomal escape. Thus, delivery vehicles must be improved to further unlock the full potential of RNA therapeutics. An emerging strategy is to modify existing or new lipid nanocarriers by incorporating bioinspired design principles. This method generally aims to improve tissue targeting, cellular uptake, and endosomal escape, addressing some of the critical issues facing the field. In this review, we introduce the different strategies for creating bioinspired lipid-based RNA carriers and discuss the potential implications of each strategy based on reported findings. These strategies include incorporating naturally derived lipids into existing nanocarriers and mimicking bioderived molecules, viruses, and exosomes. We evaluate each strategy based on the critical factors required for delivery vehicles to succeed. Finally, we point to areas of research that should be furthered to enable the more successful rational design of lipid nanocarriers for RNA delivery.

Curr Pharm Biotechnol 2021; 22:1149-1155. [PMID: 33038909 DOI: 10.2174/1389201021666201009154517] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/19/2020] [Revised: 09/15/2020] [Accepted: 09/15/2020] [Indexed: 11/22/2022]
Abstract
On a worldwide scale, the outbreak of the Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) has led to extensive damage to the health system as well as the global economy. Hitherto, there has been no approved drug or vaccine for this disease. Therefore, the use of general antiviral drugs is at the first line of treatment, though complicated with limited effectiveness and systemic side effects. Given the pathophysiology of the disease, researchers have proposed various strategies not only to find a more specific therapeutic way but also to reduce the side effects. One strategy to accomplish these goals is to use CRISPR/Cas13 system. Recently, a group of scientists has used the CRISPR/Cas13 system, which is highly effective in eliminating the genome of RNA viruses. Due to the RNA nature of the coronavirus genome, it seems that this system can be effective against the disease. The main challenge regarding the application of this system is to deliver it to the target cells efficiently. To solve this challenge, it seems that using virosomes with protein S on their membrane surface can be helpful. Studies have shown that protein S interacts with its specific receptor in target cells named Angiotensin-Converting Enzyme 2 (ACE2). Here, we propose if CRISPR/Cas13 gene constructs reach the infected cells efficiently using a virosomal delivery system, the virus genome will be cleaved and inactivated. Considering the pathophysiology of the disease, an important step to implement this hypothesis is to embed protein S on the membrane surface of virosomes to facilitate the delivery of gene constructs to the target cells.

Abstract
There are still great challenges for the effective treatment of infectious diseases, although considerable achievement has been made by using antiviral and antimicrobial agents varying from small-molecule drugs, peptides/proteins, to nucleic acids. The nanomedicine approach is emerging as a new strategy capable of overcoming disadvantages of molecular therapeutics and amplifying their anti-infective activities, by localized delivery to infection sites, reducing off-target effects, and/or attenuating resistance development. Nanotechnology, in combination with bioinspired and biomimetic approaches, affords additional functions to nanoparticles derived from synthetic materials. Herein, we aim to provide a state-of-the-art review on recent progress in biomimetic and bioengineered nanotherapies for the treatment of infectious disease. Different biomimetic nanoparticles, derived from viruses, bacteria, and mammalian cells, are first described, with respect to their construction and biophysicochemical properties. Then, the applications of diverse biomimetic nanoparticles in anti-infective therapy are introduced, either by their intrinsic activity or by loading and site-specifically delivering various molecular drugs. Bioinspired and biomimetic nanovaccines for prevention and/or therapy of infectious diseases are also highlighted. At the end, major translation issues and future directions of this field are discussed.

Abstract
The possibility of targeted drug delivery to a specific tissue, organ, or cell has opened new promising avenues in treatment development. The technology of targeted delivery aims to create multifunctional carriers that are capable of long circulation in the patient's organism and possess low toxicity at the same time. The surface of modern synthetic carriers has high structural similarity to the cell membrane, which, when combined with additional modifications, also promotes the transfer of biological properties in order to penetrate physiological barriers effectively. Along with artificial nanocages, further efforts have recently been devoted to research into extracellular vesicles that could serve as natural drug delivery vehicles. This review provides a detailed description of targeted delivery systems that employ lipid and lipid-like nanocages, as well as extracellular vesicles with a high level of biocompatibility, highlighting genetically encoded drug delivery vehicles.

Abstract
A polyelectrolyte microcapsule-based layer-by-layer (LbL) technique has been widely used as a multifunctional vehicle for combined tumor therapy. Meanwhile, with the rapid development of combined tumour therapy, the challenge for designing multifunctional drug delivery system has attracted much more attention. Herein, we developed a new type of microcapsule (MC) system called MPA@siRNA@DOX@MC, which conjugated with siRNA and DOX as well as ICG-Der-02 (MPA) by electrostatic absorption. MPA as indocyanine green (ICG) fluorescence dye, exhibiting high fluorescence emission and photothermal conversion ability under NIR laser irradiation, was uploaded onto this drug system for realizing the controllable drug release and cancer theranostics. In addition, the results revealed that MPA@siRNA@DOX@MC possessed several ideal properties including high drug-loading capacity, excellent siRNA transfection efficiency, siRNA sequence protection and remarkably improved tumour-targeting capacity. Moreover, the combined therapy based on this drug system displayed improved therapeutic efficacy and negligible side effects both in vivo and in vitro experiment. Ultimately, MPA@siRNA@DOX@MC drug delivery system successfully combined the photothermal therapy and chemotherapy with controlled siRNA sequence silencing may have a promising potential in combined tumor therapy.

Abstract
The major goal of immunity is maintaining host survival. Toward this, immune cells recognize and eliminate targets that pose a danger. Primarily, these are external invaders (pathogens) and internal invaders (cancers). Their recognition relies on distinguishing foreign components (antigens) from self-antigens. Since cancer cells are the host's own cells that are harmfully altered, they are difficult to distinguish from normal self. Furthermore, the antigens least resembling the host are often sequestered in parts of the tumor least accessible to immune responses. Therefore, to sufficiently boost immunity, these tumor antigens must be exposed to the immune system. Toward this, nanoparticles provide an innovating means of tumor antigen presentation and are destined to become an integral part of cancer immunotherapy.

Abstract
Vaccines have classically been used for disease prevention. Modern clinical vaccines are continuously being developed for both traditional use as well as for new applications. Typically thought of in terms of infectious disease control, vaccination approaches can alternatively be adapted as a cancer therapy. Vaccines targeting cancer antigens can be used to induce anti-tumour immunity and have demonstrated therapeutic efficacy both pre-clinically and clinically. Various approaches now exist and further establish the tremendous potential and adaptability of anti-cancer vaccination. Classical strategies include ex vivo-loaded immune cells, RNA- or DNA-based vaccines and tumour cell lysates. Recent oncolytic virus development has resulted in a surge of novel viruses engineered to induce powerful tumour-specific immune responses. In addition to their use as cancer vaccines, oncolytic viruses have the added benefit of being directly cytolytic to cancer cells and thus promote antigen recognition within a highly immune-stimulating tumour microenvironment. While oncolytic viruses are perfectly equipped for efficient immunization, this complicates their use upon previous exposure. Indeed, the host's anti-viral counter-attacks often impair multiple-dosing regimens. In this review we will focus on the use of oncolytic viruses for anti-tumour vaccination. We will explore different strategies as well as ways to circumvent some of their limitations.

Abstract
Increased glycolysis is the main source of energy supply in cancer cells that use this metabolic pathway for ATP generation. Altered energy metabolism is a biochemical fingerprint of cancer cells that represents one of the "hallmarks of cancer". The immune system can prevent tumour growth by eliminating cancer cells but this editing process ultimately results in poorly immunogenic cells remaining allowing for unchallenged tumour growth. In this review we look at the glycolysis pathway as a target for cancer treatments. We also examine the interplay between the glycolysis modulation and the immune response as an anti-cancer therapy.

Abstract
Abstract
Budded virus (BV) particles of baculovirus (Autographa californica nucleopolyhedrovirus, AcNPV) are harvested from the supernatant of liquid culture of Sf9 host cells by ultracentrifugation. Using polyacrylamide gel electrophoresis, Western blot and transmission electron microscopy (TEM) of BV samples fractionated closely by sucrose density gradient centrifugation, we observed that BVs exhibited different qualities depending on whether they had been harvested from the supernatant from a standing (static), shaking (suspension), or standing/shaking (pre-/post-infection) culture of Sf9 cells. The amount of BV protein apparently increased in the order of standing, standing/shaking, and shaking procedure, and the yield of intact particles showed an opposite trend. TEM observation clearly showed that appropriate fractions of the standing and standing/shaking cultures contained more intact BV particles than those from the shaking culture. These results suggest that the qualities of recombinant BV particles may be related to the culture conditions of the host cells.

Abstract
As drug delivery systems, nanocarriers should be capable of executing the following functions: evasion of the host immune system, targeting to the diseased site, entering cells, escaping from endosomes, and releasing payloads into the cytoplasm. Since viruses perform some or all of these functions, they are considered naturally occurring nanocarriers. To achieve biomimicry of the hepatitis B virus (HBV), we generated the "bio-nanocapsule" (BNC)-which deploys the human hepatocyte-targeting domain, fusogenic domain, and polymerized-albumin receptor domain of HBV envelope L protein on its surface-by overexpressing the L protein in yeast cells. BNCs are capable of delivering various payloads to the cytoplasm of human hepatic cells specifically in vivo, which is achieved via formation of complexes with various materials (e.g., drugs, nucleic acids, and proteins) by electroporation, fusion with liposomes, or chemical modification. In this review, we describe BNC-related technology, discuss retargeting strategies for BNCs, and outline other virus-inspired nanocarriers.

Abstract
Vaccines represent the most relevant contribution of immunology to human health. However, despite the remarkable success achieved in the past years, many vaccines are still missing in order to fight important human pathologies and to prevent emerging and re-emerging diseases. For these pathogens the known strategies for making vaccines have been unsuccessful and thus, new avenues should be investigated to overcome the failure of clinical trials and other important issues including safety concerns related to live vaccines or viral vectors, the weak immunogenicity of subunit vaccines and side effects associated with the use of adjuvants. A major hurdle of developing successful and effective vaccines is to design antigen delivery systems in such a way that optimizes antigen presentation and induces broad protective immune responses. Recent advances in vector delivery technologies, immunology, vaccinology and system biology, have led to a deeper understanding of the molecular and cellular mechanisms by which vaccines should stimulate both arms of the adaptive immune responses, offering new strategies of vaccinations. This review is an update of current strategies with respect to live attenuated and inactivated vaccines, DNA vaccines, viral vectors, lipid-based carrier systems such as liposomes and virosomes as well as polymeric nanoparticle vaccines and virus-like particles. In addition, this article will describe our work on a versatile and immunogenic delivery system which we have studied in the past decade and which is derived from a non-pathogenic prokaryotic organism: the “E2 scaffold” of the pyruvate dehydrogenase complex from Geobacillus stearothermophilus.

Development of Rous sarcoma Virus-like Particles Displaying hCC49 scFv for Specific Targeted Drug Delivery to Human Colon Carcinoma Cells. Pharm Res 2015; 32:3699-707.

Abstract
PURPOSE Virus-like particles (VLPs) have been used as drug carriers for drug delivery systems. In this study, hCC49 single chain fragment variable (scFv)-displaying Rous sarcoma virus-like particles (RSV VLPs) were produced in silkworm larvae to be a specific carrier of an anti-cancer drug. METHOD RSV VLPs displaying hCC49 scFv were created by the fusion of the transmembrane and cytoplasmic domains of hemagglutinin from influenza A (H1N1) virus and produced in silkworm larvae. The display of hCC49 scFv on the surface of RSV VLPs was confirmed by enzyme-linked immunosorbent assay using tumor-associated glycoprotein-72 (TAG-72), fluorescent microscopy, and immunoelectron microscopy. Fluorescein isothiocyanate (FITC) or doxorubicin (DOX) was incorporated into hCC49 scFv-displaying RSV VLPs by electroporation and specific targeting of these VLPs was investigated by fluorescent microscopy and cytotoxicity assay using LS174T cells. RESULTS FITC was delivered to LS174T human colon adenocarcinoma cells by hCC49 scFv-displaying RSV VLPs, but not by RSV VLPs. This indicated that hCC49 scFv allowed FITC-loaded RSV VLPs to be delivered to LS174T cells. DOX, which is an anti-cancer drug with intrinsic red fluorescence, was also loaded into hCC49 scFv-displaying RSV VLPs by electroporation; the DOX-loaded hCC49 scFv-displaying RSV VLPs killed LS174T cells via the specific delivery of DOX that was mediated by hCC49 scFv. HEK293 cells were alive even though in the presence of DOX-loaded hCC49 scFv-displaying RSV VLPs. CONCLUSION These results showed that hCC49 scFv-displaying RSV VLPs from silkworm larvae offered specific drug delivery to colon carcinoma cells in vitro. This scFv-displaying enveloped VLP system could be applied to drug and gene delivery to other target cells.

Abstract
A replication-incompetent hemagglutinating virus of Japan (HVJ) envelope (HVJ-E) induces apoptosis selectively in cancer cells. Fragments of the viral RNA genome transported by HVJ-E are recognized by retinoic acid-inducible gene I (RIG-I) and mitochondrial antiviral signaling (MAVS). Specific pro-apoptotic factor are selectively upregulated in cancer cells downstream of the RIG-I/MAVS pathway.

Abstract
Tumor microenvironments include a number of fibrin clots due to the microbleeding caused by cancer cell invasion into blood vessels, which suggests the potential utility of a platelet vector for systemic cancer treatment. We previously reported that inactivated Sendai virus (hemagglutinating virus of Japan; HVJ) envelope (HVJ-E) activates anti-tumor immunity and induces cancer cell-selective apoptosis. The hemagglutination activity that blocks the systemic administration of HVJ-E was dramatically attenuated by incorporation into platelets. Platelets incorporating HVJ-E (PH complex) were then injected into the tail veins of B16F10 melanoma-bearing mice. The PH complex primarily accumulated in tumor tissues and caused the significant accumulation of various immune cells in the tumor bed. Injections of the PH complex to the melanoma-bearing mouse significantly reduced the tumor size, and the tumor growth was ultimately arrested. Secretion of the chemokine regulated upon activation normal T-expressed and presumably secreted (RANTES) was upregulated following PH stimulation. The RANTES-depletion in melanoma-bearing mice significantly attenuated the cytotoxic T lymphocyte activity and led to a dramatic abrogation of the mouse melanoma suppression induced by the PH complex. Thus, a platelet vector incorporating viral particles, a Trojan horse for cancer treatment, will provide a new approach for cancer therapy using oncolytic viruses.

Abstract
The basic concept of virosomes is the controlled in vitro assembly of virus-like particles from purified components. The first generation of influenza virosomes developed two decades ago is successfully applied in licensed vaccines, providing a solid clinical safety and efficacy track record for the technology. In the meantime, a second generation of influenza virosomes has evolved as a carrier and adjuvant system, which is currently applied in preclinical and clinical stage vaccine candidates targeting various prophylactic and therapeutic indications. The inclusion of additional components to optimize particle assembly, to stabilize the formulations, or to enhance the immunostimulatory properties have further improved and broadened the applicability of the platform.

Recent advances and developments in the antitumor effect of the HVJ envelope vector on malignant melanoma: from the bench to clinical application. Cancer Gene Ther 2013; 20:599-605. [PMID: 24157924 DOI: 10.1038/cgt.2013.61] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/14/2013] [Revised: 08/23/2013] [Accepted: 09/17/2013] [Indexed: 12/31/2022]
Abstract
Inactivated Sendai virus particles (hemagglutinating virus of Japan envelope; HVJ-E) are considered to be safe and efficient non-viral vectors used for drug delivery, since they can incorporate DNA, RNA, proteins and drugs. We have recently found that HVJ-E has a novel antitumor immune effect using a colon cancer model. HVJ-E has also been shown to have both direct and immune-mediated indirect actions against malignancy. Intratumoral injection of an inactivated HVJ-E solution significantly reduced the tumor volume and prevented spontaneous lung metastasis, leading to an increased overall survival in C57/BL6 mice transplanted with B16/BL6 mouse melanoma cells, and even in immunodeficient mice transplanted with Mewo human melanoma cells. No severe adverse effects including laboratory data abnormalities or anaphylactic reactions were observed. The comprehensive mechanism(s) underlying the immunological effects of HVJ-E appear to include not only enhanced effector T cell- and/or natural killer (NK) cell-mediated immunity, but also rescue from regulatory T cell (Treg)-mediated immunosuppression, presumably through the interleukin-6 secretion from dendritic cells stimulated by HVJ-E. Since a protocol for a clinical study of HVJ-E in malignant melanoma was approved in 2009 by the ethics committee of Osaka University and of the Medical Center for Translational Research in Osaka University Hospital, a phase I/IIa study for advanced malignant melanoma patients was just started. In this review, we show several favorable results regarding the antitumor effects of HVJ-E and describe the novel mechanism underlying this tumor immune response. Since we are conducting a phase I/IIa clinical trial using HVJ-E in advanced melanoma patients on the basis of preclinical results, detailed clinical information and immune-monitoring data are also introduced. The development of new therapeutic modalities for advanced melanoma patients is urgently needed, and we hope that HVJ-E may provide one such treatment.

Abstract
Inactivated Sendai virus (HVJ-E) directly kills cancer cells by inducing apoptosis through a mechanism mediated by Janus kinases/signal transducers and activators of transcription (JAK/STAT) signaling pathways. However, whether other signaling pathways are involved remain largely unknown. This study aimed to investigate the mechanism underlying HVJ-E-induced apoptosis in murine B16F10 melanoma cells. We found that HVJ-E induced B16F10 cell apoptosis via the caspase pathway, particularly caspase-9, which mediates the intrinsic apoptotic pathway. Mitogen-activated protein kinase (MAPK) pathway activation also contributed to HVJ-E-induced apoptosis. Whereas caspase pathway involvement depended on both IFN-β promoter stimulator-1 (IPS-1) and type I interferon (IFN), MAPK pathway activation was independent of type I IFN but involved IPS-1. In addition, intratumoral HVJ-E treatment displayed a direct oncolytic effect in an in vivo BALB/c nude mouse melanoma model. Collectively, our data provides new insights into the mechanism underlying HVJ-E-induced apoptosis in tumor cells.

Abstract
Nanoparticles have been extensively developed for therapeutic and diagnostic applications. While the focus of nanoparticle trafficking in vivo has traditionally been on drug delivery and organ-level biodistribution and clearance, recent work in cancer biology and infectious disease suggests that targeting different cells within a given organ can substantially affect the quality of the immunological response. Here, we examine the cell-level biodistribution kinetics after administering ultrasmall Pluronic-stabilized poly(propylene sulfide) nanoparticles in the mouse. These nanoparticles depend on lymphatic drainage to reach the lymph nodes and blood, and then enter the spleen rather than the liver, where they interact with monocytes, macrophages and myeloid dendritic cells. They were more readily taken up into lymphatics after intradermal (i.d.) compared to intramuscular administration, leading to ∼50% increased bioavailability in blood. When administered i.d., their distribution favored antigen-presenting cells, with especially strong targeting to myeloid cells. In tumor-bearing mice, the monocytic and the polymorphonuclear myeloid-derived suppressor cell compartments were efficiently and preferentially targeted, rendering this nanoparticulate formulation potentially useful for reversing the highly suppressive activity of these cells in the tumor stroma.

Abstract
Neurodegenerative diseases, such as Alzheimer's disease and Parkinson's disease represent a huge unmet medical need. The prevalence of both diseases is increasing, but the efficacy of treatment is still very limited due to various factors including the blood brain barrier (BBB). Drug delivery to the brain remains the major challenge for the treatment of all neurodegenerative diseases because of the numerous protective barriers surrounding the central nervous system. New therapeutic drugs that cross the BBB are critically needed for treatment of many brain diseases. One of the significant factors on neurotherapeutics is the constraint of the blood brain barrier and the drug release kinetics that cause peripheral serious side effects. Contrary to common belief, neurodegenerative and neurological diseases may be multisystemic in nature, and this presents numerous difficulties for their potential treatment. Overall, the aim of this paper is to summarize the last findings and news related to liposome technology in the treatment of neurodegenerative diseases and demonstrate the potential of this technology for the development of novel therapeutics and the possible applications of liposomes in the two most widespread neurodegenerative diseases, Alzheimer's disease and Parkinson's disease.
