Abstract
Patients with dementia are increasing with the aging of the population, and dementia has become a disease with high unmet medical needs. Glucagon-like peptide-1 (GLP-1), a neuropeptide, has been reported to improve learning and memory following intracerebroventricular administration. We focused on intranasal administration, which can deliver drugs noninvasively and efficiently to the brain. Although much of the human nasal mucosa is occupied by respiratory epithelium, many capillaries are present in the paracellular route of respiratory epithelium. Therefore, to incorporate GLP-1 into cells, we created a GLP-1 derivative by adding cell-penetrating peptides (CPP) and penetration accelerating sequences (PAS) to GLP-1. We investigated in vitro and in vivo function of PAS-CPP-GLP-1 to enable the translocation of GLP-1 directly from nose to brain. PAS-CPP-GLP-1 enhanced cellular uptake by macropinocytosis with CPP, efficiently escaped from the endosomes due to PAS, and exited the cells. PAS-CPP-GLP-1 also transited trigeminal nerve cells through axon transport and migrated to the adjacent trigeminal nerve cell. Moreover, PAS-CPP-GLP-1 showed significant improvement in learning memory in mice within 20 min of intranasal administration. These results suggested CPP and PAS may be important for the efficient transfer of GLP-1 to the site of action in the brain following intranasal administration.

Abstract
In our previous study, we created a glucagon-like peptide-2 (GLP-2) derivative with the functional sequence PAS-CPP to achieve efficient uptake by the respiratory epithelium and trigeminal nerve. By using octaarginine for cell penetrating peptides (CPP) and FFLIPKG, a reverse sequence of a part of the cathepsin D sequence for the penetration accelerating sequence (PAS), we found that the derivative was taken up by the cells through macropinocytosis and efficiently escaped from the endosomes and exited the cells. Moreover, it showed drug effects by intranasal (in.) administration at the same dose as intracerebroventricular (icv.) administration, which is direct drug administration into the brain. The purpose of this study was to elucidate the cause of the drug effect of in. administered PAS-CPP-GLP-2 at the same dose as that by icv. Administration. The present results suggested that although icv. Administered PAS-CPP-GLP-2 entered the cerebrospinal fluid, it barely penetrated the perivascular space of the brain, and therefore, only a small amount of the administered dose may have reached the site of action in the brain. In contrast, it was qualitatively suggested that in. administered PAS-CPP-GLP-2 migrates from the trigeminal nerve to the central nervous system via the principal sensory trigeminal nucleus and then through the trigeminal lemniscus. The present results show that nose-to-brain delivery by trigeminal axons, which is assumed to be a transcellular pathway, may be possible. As the drug can be delivered into the nerve, it is expected to be applied not only as a central delivery route but also for the treatment of neurological diseases.

Usefulness of cell-penetrating peptides and penetration accelerating sequence for nose-to-brain delivery of glucagon-like peptide-2. J Control Release 2021; 335:575-583. [PMID: 34116136 DOI: 10.1016/j.jconrel.2021.06.007] [Citation(s) in RCA: 17] [Impact Index Per Article: 5.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/01/2021] [Revised: 06/02/2021] [Accepted: 06/06/2021] [Indexed: 01/19/2023]
Abstract
Neuropeptides are expected as therapeutic drug candidates for central nervous system (CNS) disorders. Intracerebroventricular (i.c.v.) administration of glucagon-like peptide-2 (GLP-2) has an antidepressant-like effect not only in depression model mice but also in treatment-resistant depression model mice. However, because i.c.v. administration is very invasive, research is progressing on brain delivery using intranasal administration as a non-invasive method. After intranasal administration of the drug, there are two routes to the brain. That of direct delivery from the paracellular route of olfactory epithelium to the brain via the olfactory bulb has been studied, and that of systemic absorption via the paracellular route of respiratory epithelium has been put to practical use. The high degree of vascularization and permeability of the nasal mucosa enables drug delivery via the paracellular route that leads to systemic delivery. Therefore, suppressing systemic absorption may increase drug delivery to brain, so we focused on the transcellular route. We created a GLP-2 derivative by adding cell-penetrating peptides (CPP) and penetration accelerating sequences (PAS), which are reported to provide efficient intracellular uptake, to GLP-2. However, to deliver GLP-2 by the transcellular route, GLP-2 must not only be taken up into cells but also move out of the cells. We investigated in vitro and in vivo function of PAS-CPP-GLP-2 to enable the translocation of GLP-2 directly from the nose to the brain. Derivatization of PAS-CPP-GLP-2 prevented its degradation. In the evaluation of intracellular dynamics, PAS-CPP-GLP-2 enhanced cellular uptake by macropinocytosis with CPP and promoted escape from endosomal vesicles by PAS. This study also showed that PAS-CPP-GLP-2 can move out of cells. Furthermore, only this PAS-CPP-GLP-2 showed an antidepression-like effect within 20 min of intranasal administration. Intranasal administered PAS-CPP-GLP-2 surprisingly showed the effect at the same dose with i.c.v. administration, but intravenous administered PAS-CPP-GLP-2 did not show the effect. These results suggested that PAS-CPP-GLP-2 can be efficiently delivered from the nose to the CNS and show a pharmacological effect, demonstrating the usefulness of PAS and CPP for nose-to-brain delivery of GLP-2.

Abstract
Live-cell delivery of a fully synthetic protein having selectivity towards a particular target is a promising approach with potential applications for basic research and therapeutics. Cell-penetrating peptides (CPPs) allow the cellular delivery of proteins but mostly result in endosomal entrapment, leading to lack of bioavailability. Herein, we report the design and synthesis of a CPP fused to 4-((4-(dimethylamino)phenyl)azo)benzoic acid (DABCYL) to enhance cellular uptake of fluorescently labelled synthetic protein analogues in low micromolar concentration. The attachment of cyclic deca-arginine (cR10) modified with a single lysine linked to DABCYL to synthetic ubiquitin (Ub) and small ubiquitin-like modifier-2 (SUMO-2) scaffolds resulted in a threefold higher uptake efficacy in live cells compared to the unmodified cR10. We could also achieve cR10DABCYL-assisted delivery of Ub and a Ub variant (Ubv) based activity-based probes for functional studies of deubiquitinases in live cells.

Abstract
Small synthetic peptides capable of crossing biological membranes represent valuable tools in cell biology and drug delivery. While several cell-penetrating peptides (CPPs) of natural or synthetic origin have been reported, no peptide is currently known to cross both cytoplasmic and outer embryonic membranes. Here, we describe a method to engineer membrane-permeating cyclic peptides (MPPs) with broad permeation activity by screening mRNA display libraries of cyclic peptides against embryos at different developmental stages. The proposed method was demonstrated by identifying peptides capable of permeating Drosophila melanogaster (fruit fly) embryos and mammalian cells. The selected peptide cyclo[Glut-MRKRHASRRE-K*] showed a strong permeation activity of embryos exposed to minimal permeabilization pretreatment, as well as human embryonic stem cells and a murine fibroblast cell line. Notably, in both embryos and mammalian cells, the cyclic peptide outperformed its linear counterpart and the control MPPs. Confocal microscopy and single cell flow cytometry analysis were utilized to assess the degree of permeation both qualitatively and quantitatively. These MPPs have potential application in studying and nondisruptively controlling intracellular or intraembryonic processes.

Abstract
Advancement in our knowledge of deubiquitinases (DUBs) and their biological functions requires biochemical tools permitting interrogation of DUB activities under physiologically relevant conditions. Activity-based DUB probes (DUB ABPs) have been widely used in investigating the function and activity of DUBs. However, most ubiquitin (Ub)-based DUB ABPs are not cell-permeable, limiting their utility to purified proteins and cell lysates. Lysis of cells usually leads to dilution of the cytoplasm and disruption of the normal cellular organization, which may alter the activity of many DUBs and DUB complexes. Here, we report a new class of cell-permeable DUB ABPs that enable intracellular DUB profiling. We used a semisynthetic approach to generate modular ubiquitin-based DUB probes containing a reactive warhead for covalent trapping of DUBs with a catalytic cysteine. We employed cell-penetrating peptides (CPPs), particualrly cyclic polyarginine (cR10), to deliver the DUB ABPs into cells, as confirmed using live-cell fluorescence microscopy and DUB ABPs containing a fluorophore at the C-terminus of Ub. In comparison to TAT, enhanced intacellular delivery was observed through conjugation of a cyclic polyarginine (cR10) to the N-terminus of ubiquitin via a disulfide linkage. Using the new cell-permeable DUB ABPs, we carried out DUB profiling in intact HeLa cells, and identified active DUBs using immunocapture and label-free quantitative mass spectrometry. Additionally, we demonstrated that the cell-permeable DUB ABPs can be used in assessing the inhibition of DUBs by small-molecule inhibitors in intact cells. Our results indicate that cell-permeable DUB ABPs hold great promise in providing a better understanding of the cellular functions of DUBs and advancing drug discovery efforts targeting human DUBs.

Abstract
UNLABELLED Targeting neural stem cells (NSCs) in the adult brain represents a promising approach for developing new regenerative strategies, because these cells can proliferate, self-renew, and differentiate into new neurons, astrocytes, and oligodendrocytes. Previous work showed that the NFL-TBS.40-63 peptide, corresponding to the sequence of a tubulin-binding site on neurofilaments, can target glioblastoma cells, where it disrupts their microtubules and inhibits their proliferation. We show that this peptide targets NSCs in vitro and in vivo when injected into the cerebrospinal fluid. Although neurosphere formation was not altered by the peptide, the NSC self-renewal capacity and proliferation were reduced and were associated with increased adhesion and differentiation. These results indicate that the NFL-TBS.40-63 peptide represents a new molecular tool to target NSCs to develop new strategies for regenerative medicine and the treatment of brain tumors. SIGNIFICANCE In the present study, the NFL-TBS.40-63 peptide targeted neural stem cells in vitro when isolated from the subventricular zone and in vivo when injected into the cerebrospinal fluid present in the lateral ventricle. The in vitro formation of neurospheres was not altered by the peptide; however, at a high concentration of the peptide, the neural stem cell (NSC) self-renewal capacity and proliferation were reduced and associated with increased adhesion and differentiation. These results indicate that the NFL-TBS.40-63 peptide represents a new molecular tool to target NSCs to develop new strategies for regenerative medicine and the treatment of brain tumors.

Abstract
A field of recent diagnostics and therapeutics has been advanced with quantum dots (QDs). QDs have developed into new formats of biomolecular sensing to push the limits of detection in biology and medicine. QDs can be also utilized as bio-probes or labels for biological imaging of living cells and tissues. More recently, QDs has been demonstrated to construct a multifunctional nanoplatform, where the QDs serve not only as an imaging agent, but also a nanoscaffold for diagnostic and therapeutic modalities. This review highlights the promising applications of multi-functionalized QDs as advanced nanosensors for diagnosing cancer and as innovative fluorescence probes for in vitro or in vivo stem cell imaging in regenerative medicine.

Abstract
INTRODUCTION Macromolecular therapeutics, including enzymes, transcription factors, siRNAs, peptides and large synthetic molecules, can potentially be used to treat human diseases by targeting intracellular molecular pathways and modulating biological responses. However, large macromolecules have no ability to enter cells and require delivery vehicles. Protein transduction domains (PTDs), also known as cell-penetrating peptides (CPPs), are a diverse class of peptides that can deliver macromolecules into cells. AREAS COVERED In this review, we cover the uptake and usage of arginine-rich PTDs/CPPs (TAT-PTD, Penetratin/Antp and 8R). We review the endocytosis-mediated uptake of these peptides and highlight three important steps: i) cell association; ii) internalization and iii) endosomal escape. We also discuss the array of different cargos that have been delivered by cationic PTDs/CPPs as well as cellular processes and biological responses that have been modulated. EXPERT OPINION PTDs/CPPs have shown great potential to deliver otherwise undeliverable macromolecular therapeutics into cells for experimentation in cell culture and in animal disease models in vivo. Moreover, over 25 clinical trials have been performed predominantly using the TAT-PTD. However, more work is still needed. Endosomal escape and target-cell specificity remain two of the major future challenges.

Abstract
Induced pluripotent stem (iPS) cells have received remarkable attention as the cell sources for clinical applications of regenerative medicine including stem cell therapy. Additionally, labeling technology is in high demand for tracing transplanted cells used in stem cell therapy. In this study, we used quantum dots (QDs), which have distinct fluorescence abilities in comparison with traditional probes, as the labeling materials and investigated whether iPS cells could be labeled with QDs with no cytotoxicity. iPS cells could not be labeled with QDs alone but required the use of cell-penetrating peptides such as octaarginine (R8). No significant cytotoxicity to iPS cells was confirmed by up to 8 nM QDs, and the iPS cells labeled with QDs maintained their undifferentiated state and pluripotency. These data suggest that QDs can be used for fluorescence labeling of iPS cells.

Abstract
Regenerative medicine is a new interdisciplinary field in biomedical science, which aims at the repair or replacement of the defective tissue or organ by congenital defects, age, injury, or disease. Various cell-related techniques such as stem cell-based biotherapy are a hot topic in the current press, and stem cell research can help us to expand our understanding of development as well as the pathogenesis of disease. In addition, new technology such as reprogramming or dedifferentiation and transdifferentiation open a new area for regenerative medicine. Here we review new approaches of these technologies used for cell-based therapy and discuss future directions and challenges in the field of regeneration.

[PMID: 23603097 DOI: 10.1016/j.ijpharm.2013.04.004] [Citation(s) in RCA: 19] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/21/2013] [Revised: 03/29/2013] [Accepted: 04/02/2013] [Indexed: 12/12/2022]
Abstract
Glioblastoma are the most frequent and aggressive tumour of the nervous system despite surgical resection associated with chemotherapy and radiotherapy. Recently, we showed that the NFL-TBS.40-63 peptide corresponding to the sequence of a tubulin-binding site of neurofilaments, enters selectively in glioblastoma cells where it blocks microtubule polymerization, inhibits their proliferation, and reduces tumour development in rats bearing glioblastoma (Bocquet et al., 2009; Berges et al., 2012a). Here, we characterized the molecular mechanism responsible for the uptake of NFL-TBS.40-63 peptide by glioblastoma cells. Unlike other cell penetrating peptides (CPPs), which use a balance between endocytosis and direct translocation, the NFL-TBS.40-63 peptide is unable to translocate directly through the membrane when incubated with giant plasma membrane vesicles. Then, using a panel of markers and inhibitors, flow cytometry and confocal microscopy investigations showed that the uptake occurs mainly through endocytosis. Moreover, glycosaminoglycans and αVβ3 integrins are not involved in the NFL-TBS.40-63 peptide recognition and internalization by glioblastoma cells. Finally, the signalling of tyrosine kinase receptors is involved in the peptide uptake, especially via EGFR overexpressed in tumour cells, indicating that the uptake of NFL-TBS.40-63 peptide by glioblastoma cells is related to their abnormally high proliferative activity.

Abstract
Stem cells are self-renewable cells with the differentiation capacity to develop into somatic cells with biological functions. This ability to sustain a renewable source of multi- and/or pluripotential differentiation has brought new hope to the field of regenerative medicine in terms of cell therapy and tissue engineering. Moreover, stem cells are invaluable tools as in vitro models for studying diverse fields, from basic scientific questions such as developmental processes and lineage commitment, to practical application including drug screening and testing. The stem cells with widest differentiation potential are pluripotent stem cells (PSCs), which are rare cells with the ability to generate somatic cells from all three germ layers. PSCs are considered the most optimal choice for therapeutic potential of stem cells, bringing new impetus to the field of regenerative medicine. In this article, we discuss the therapeutic potential of human PSCs (hPSCs) including human embryonic stem cells (hESCs) and human induced pluripotent stem cells (hiPSCs), reviewing the current preclinical and clinical data using these stem cells. We describe the classification of different sources of hPSCs, ongoing research, and currently encountered clinical obstacles of these novel and versatile human stem cells.

Abstract
This study evaluated the tumorigenesis risk of induced pluripotent stem (iPS) cells after transplantation into the cochlea. One mouse embryonic stem (ES) cell line and three mouse iPS cell lines, one derived from adult mouse tail-tip fibroblasts (TTFs) and two from mouse embryonic fibroblasts (MEFs), were neurally induced by stromal cell-inducing activity. Before transplantation, the efficiency of neural induction and the proportion of residual undifferentiated cells were evaluated using immunocytochemistry, and no significant differences were observed in the ratios of colonies expressing βIII tubulin, nestin, or octamer (Oct)3/4. Four weeks after transplantation into the cochleae of neonatal mice, the number of surviving transplants of TTF-derived iPS cells generated by retroviral infection was significantly higher than those of MEF-derived iPS cells generated by plasmid transfection. Teratoma formation was identified in one of five cochleae transplanted with TTF-derived iPS cells. However, no significant differences were found in the cell proliferation activity or the extent of differentiation into mature neurons among the cell lines. These findings emphasize the necessity of selecting appropriate iPS cell lines and developing methods to eliminate undifferentiated cells after neural induction, in order to establish safe iPS cell-based therapy for the inner ear.

Abstract
BACKGROUND Treatment of allergic airways disease including asthma remains primarily local immunosuppression with topical corticosteroid and symptomatic management with antihistamines and anti-leucotrienes. We have developed a novel topical therapy designed to specifically inhibit the events associated with Th2 cell activation. OBJECTIVE We assessed the efficacy of our cell-penetrating STAT-6 inhibitory peptide (STAT-6-IP), a novel treatment for allergic airways disease, in a model of chronic ragweed-induced asthma. METHODS Six- to eight-week-old mice were sensitized over 5 weeks with intranasal (IN) exposures to whole ragweed allergen without adjuvant. Mice were then IN challenged with Amba 1 with and without treatment IN with STAT-6-IP and allergic responses assessed. Two weeks later, some animals were rechallenged with Amba 1 with or without STAT-6-IP. RESULTS Animals exposed to IN ragweed developed significant airway hyperresponsiveness and airways inflammation upon challenge. Cell cultures showed increases in Th2 cytokines IL-4 and IL-13. Topical STAT-6-IP treatment reduced production of Th2 cytokines, demonstrated increased expression of IL-10 and reduced frequency of cultured IL-4 positive CD4+ T cells derived from treated mice, suggesting that STAT-6-IP treatment may be immunomodulatory. Airway responsiveness to methacholine challenge in the treatment group was similarly reduced to that of the non-allergic PBS-exposed animals. Importantly, STAT-6-IP-treated mice remained hyporesponsive following second ragweed challenge 2 weeks after treatment. CONCLUSIONS AND CLINICAL RELEVANCE These data suggest that topical application of the STAT-6-IP is sufficient to inhibit allergic airways responses in animals chronically sensitized and challenged with ragweed. Data show that a single topical treatment course is sufficient to block signs of allergic responses to ragweed in the airways for at least 2 weeks. STAT-6-IP is a novel potential treatment for chronic allergic asthma.

Abstract
Protein therapy is considered an alternative approach to gene therapy for treatment of genetic-metabolic disorders. Human protein therapeutics (PTs), developed via recombinant DNA technology and used for the treatment of these illnesses, act upon membrane-bound receptors to achieve their pharmacological response. On the contrary, proteins that normally act inside the cells cannot be developed as PTs in the conventional way, since they are not able to "cross" the plasma membrane. Furthermore, in mitochondrial disorders, attributed either to depleted or malfunctioned mitochondrial proteins, PTs should also have to reach the subcellular mitochondria to exert their therapeutic potential. Nowadays, there is no effective therapy for mitochondrial disorders. The development of PTs, however, via the Protein Transduction Domain (PTD) technology offered new opportunities for the deliberate delivery of human recombinant proteins inside eukaryotic subcellular organelles. To this end, mitochondrial disorders could be clinically encountered with the delivery of human mitochondrial proteins (engineered via recombinant DNA and PTD technologies) at specific intramitochondrial sites to exert their function. Overall, PTD-mediated Protein Replacement Therapy emerges as a suitable model system for the therapeutic approach for mitochondrial disorders.
