[PMID: 38307741 DOI: 10.1016/j.ijbiomac.2024.129684] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/27/2023] [Revised: 12/28/2023] [Accepted: 01/21/2024] [Indexed: 02/04/2024]
Abstract
Incorporation of growth factors, signaling molecules and drugs can be vital for the success of tissue engineering in complex structures such as the dentoalveolar region. This has led to the development of a variety of drug release systems. This study aimed to develop pNIPAM-methylcellulose microgels with different synthesis parameters based on a 23 full factorial design of experiments for this application. Microgel properties, including volume phase transition temperature (VPTT), hydrodynamic size, drug loading and release, and cytocompatibility were systematically evaluated. The results demonstrated successful copolymerization and development of the microgels, a hydrodynamic size ranging from ∼200 to ∼500 nm, and VPTT in the range of 34-39 °C. Furthermore, loading of genipin, capable of inducing odontoblastic differentiation, and its sustained release over a week was shown in all formulations. Together, this can serve as a solid basis for the development of tunable drug-delivering pNIPAM-methylcellulose microgels for specific tissue engineering applications.

Abstract
Administration of temperature-responsive drug carriers that release anticancer drugs at high temperatures can benefit hyperthermia therapies because of the synergistic effect of anticancer drug molecules and high temperature on killing the cancer cells. In this study, we design and characterize a new temperature-responsive nanocarrier based on a naturally occurring and biocompatible clay mineral, halloysite nanotubes. Poly(N-isopropylacrylamide) brushes were grown on the surface of halloysite nanotubes using a combination of mussel-inspired dopamine polymerization and surface-initiated atom transfer radical polymerization. The chemical structure of the hybrid materials was investigated using X-ray photoelectron spectroscopy, thermogravimetric analysis and energy-dispersive X-ray spectroscopy. The hybrid material was shown to have a phase transition temperature of about 32 °C, corresponding to a 40 nm thick polymer layer surrounding the nanotubes. Cell studies suggested that grafting of poly(N-isopropylacrylamide) brushes on the polydopamine-modified halloysite nanotubes suppresses the cytotoxicity caused by the polydopamine interlayer and drug release studies on nanotubes loaded with doxorubicin showed that thanks to the poly(N-isopropylacrylamide) brushes a temperature-dependent drug release is observed. Finally, a fluorescent dye molecule was covalently attached to the polymer-grafted nanotubes and stimulated emission depletion nanoscopy was used to confirm the internalization of the nanotubes in HeLa cells.

Abstract
Rapid endothelialization on small diameter artificial blood vessels is an effective strategy to facilitate long-term patency and inhibit thrombosis. The gene delivery can enhance the proliferation and migration of endothelial cells (ECs), which is beneficial for rapid endothelialization. REDV-G-TAT-G-NLS-Cys (abbreviated as TP-G) peptide could weakly condense pEGFP-ZNF580 (pZNF580) and transfect ECs, but its transfection efficiency was still very low because of its low positive charge, low stability and weak endosome escape ability. In order to develop more stable and efficient gene carriers with low cytotoxicity, in the present study, we conjugated different amounts of TP-G peptide onto poly(lactide-co-glycolide)-g-polyethylenimine (PLGA-g-PEI) amphiphilic copolymers via a hetero-poly(ethylene glycol) spacer (OPSS-PEG-NHS). The TP-G peptide and PEI could cooperatively and strongly condense pZNF580. The carrier's cytotoxicity was reduced by the introduction of poly(ethylene glycol) spacer. They condensed pZNF580 to form gene complexes (PPP-TP-G/pZNF580) with suitable size and positive zeta potential for gene delivery. The transfected ECs promoted their migration ability as demonstrated by cell migration assay. The results of cellular uptake and confocal laser scanning microscopy showed significantly high internalization efficiency, endosomal/lysosomal escape and nucleus location of pZNF580 by this multifunctional TP-G peptide sequence conjugated gene delivery system. Furthermore, several inhibitors were used to study the cellular uptake pathways of PPP-TP-G/pZNF580 complexes. The results showed that PPP-TP-G2/Cy5-oligonucleotide complexes exhibited the optimized endocytosis pathways which facilitated for cellular uptake. In conclusion, the multifunctional TP-G peptide conjugated gene carriers could promote the transfection efficiency due to the multifunction of REDV, cell-penetrating peptide and nuclear localization signal in the peptide sequence, which could be a suitable gene carrier for endothelialization.

Abstract
The present study aims in the understanding of the effect of oligo(ethylene glycol)-based biocompatible microgels inner structure on the encapsulation/release mechanisms of different types of cosmetic active molecules. For that, multi-responsive microgels were synthesized using three types of cross-linkers: ethylene glycol dimethacrylate (EGDMA), oligo(ethylene glycol) diacrylate (OEGDA) and N,N-methylenebisacrylamide (MBA). The inner morphology of the microgels synthesized was studied by 1H-nuclear magnetic resonance (1H NMR) and small-angle neutron scattering (SANS) techniques and no effect of cross-linker type on microgel microstructure was observed in the case of analysing purified microgel dispersions. Moreover, all the microgels synthesized presented conventional swelling/de-swelling behavior as a function of temperature and pH. Two hydrophobic, one hydrophilic, and one macromolecule as cosmetic active molecules were effectively loaded into different microgel particles via hydrophobic interactions and hydrogen-bonding interactions between -OH groups of active molecules and ether oxygens of different microgel particles. Their release profiles as a function of cross-linker type used and encapsulated amounts were studied by Peppas-Sahlin model. No effect of the cross-linker type was observed due to the similar inner structure of all the microgels synthesized.

Abstract
External stimuli-responsive biomaterials represent a type of promising candidates for addressing the complexity of biological systems. In this study, a platform based on the combination of temperature-sensitive polymers and a nanotube array was developed for loading sphingosine 1-phosphate (S1P) and regulating the migration of endothelial cells (ECs) at desired conditions. The localized release dosage of effectors could be controlled by the change of environmental temperature. At a culture temperature above the lower critical solution temperature, the polymer "gatekeeper" with a collapsed conformation allowed the release of S1P, which in turn enhanced the migration of ECs. The migration rate of single cells was significantly enhanced up to 58.5%, and the collective migration distance was also promoted to 25.1% at 24 h and 33.2% at 48 h. The cell morphology, focal adhesion, organization of cytoskeleton, and expression of genes and proteins related to migration were studied to unveil the intrinsic mechanisms. The cell mobility was regulated by the released S1P, which would bind with the S1PR1 receptor on the cell membrane and trigger the Rho GTPase pathway.

Abstract
BACKGROUND Gene therapy has been developed and used in medical treatment for many years, especially for the enhancement of endothelialization and angiogenesis. But slow endosomal escape rate is still one of the major barriers to successful gene delivery. In order to evaluate whether introducing oligohistidine (Hn) sequence into gene carriers can promote endosomal escape and gene transfection or not, we designed and synthesized Arg-Glu-Asp-Val (REDV) peptide functionalized TAT-NLS-Hn (TAT: typical cell-penetrating peptide, NLS: nuclear localization signals, Hn: oligohistidine sequence, n: 4, 8 and 12) peptides with different Hn sequence lengths. pEGFP-ZNF580 (pZNF580) was condensed by these peptides to form gene complexes, which were used to transfect human umbilical vein endothelial cells (HUVECs). RESULTS MTT assay showed that the gene complexes exhibited low cytotoxicity for HUVECs. The results of cellular uptake and co-localization ratio demonstrated that the gene complexes prepared from TAT-NLS-Hn with long Hn sequence (n = 12) benefited for high internalization efficiency of pZNF580. In addition, the results of western blot analysis and PCR assay of REDV-TAT-NLS-H12/pZNF580 complexes showed significantly enhanced gene expression at protein and mRNA level. Wound healing assay and transwell migration assay also confirmed the improved proliferation and migration ability of the transfected HUVECs by these complexes. Furthermore, the in vitro and in vivo angiogenesis assay illustrated that these complexes could promote the tube formation ability of HUVECs. CONCLUSION The above results indicated that the delivery efficiency of pZNF580 and its expression could be enhanced by introducing Hn sequence into gene carriers. The Hn sequence in REDV-TAT-NLS-Hn is beneficial for high gene transfection. These REDV and Hn functionalized TAT-NLS peptides are promising gene carriers in gene therapy.

Abstract
Many therapeutic macromolecules must enter cells to take their action. However, their treatment outcomes are often hampered by their poor transportation into target cells. Therefore, efficient intracellular delivery of these macromolecules is critical for improving their therapeutic efficacy. Cell-penetrating peptide (CPP)-based approaches are one of the most efficient methods for intracellular delivery of macromolecular therapeutics. Nevertheless, poor specificity is a significant concern for systemic administrated CPP-based delivery systems. This chapter will review recent advances in CPP-mediated macromolecule delivery with a focus on various smart strategies which not only enhance the intracellular delivery but also improve the targeting specificity.

Abstract
Intelligent colloidal particles have been widely used as carriers for delivery of bioactive molecules due to the ability of controlled release. However, attention is mainly paid to the effects of their payloads, whereas the impacts of carriers are largely ignored. In this study, photo-responsive polyethylene glycol (PEG) microparticles were fabricated by using 8-arm-PEG with terminal amine groups (8-arm-PEG-NH2) and a photo-cleavable cross-linker. Due to the cleavable CO bond in the cross-linker, under UV irradiation the PEG particles could be decomposed gradually, leading to particle swelling and eventual disappearance. The PEG particles could be internalized by smooth muscle cells and HepG2 cells, and located in lysosomes. Their intracellular photo-response induced significant decrease of cell viability and increase of reactive oxygen species level.

Abstract
Poly (N-isopropylacrylamide) (pNIPAm)-based hydrogels and hydrogel particles (microgels) have been extensively studied since their discovery a number of decades ago. While their utility seems to have no limit, this feature article is focused on their development and application for sensing small molecules, macromolecules, and biomolecules. We highlight hydrogel/microgel-based photonic materials that have order in one, two, or three dimensions, which exhibit optical properties that depend on the presence and concentration of various analytes. A particular focus is put on one-dimensional materials developed in the Serpe Group.

Abstract
Disulfiram, which exhibits marked tumor inhibition mediated by copper, was encapsulated in lipid nanocapsules modified with TAT peptide (TATp) and pH-triggered sheddable PEG to target cancer cells on the basis of tumor environmental specificity. PEG-shedding lipid nanocapsules (S-LNCs) were fabricated from LNCs by decorating short PEG chains with TATp (HS-PEG(1k)-TATp) to form TATp-LNCs and then covered by pH-sensitive graft copolymers of long PEG chains (PGA-g-PEG(2k)). The DSF-S-LNCs had sizes in the range of 60-90 nm and were stable in the presence of 50% plasma. DSF-S-LNCs exhibited higher intracellular uptake and antitumor activity at pH 6.5 than at pH 7.4. The preincubation of Cu showed that the DSF cytotoxicity was based on the accumulation of Cu in Hep G2 cells. Pharmacokinetic studies showed the markedly improved pharmacokinetic profiles of DSF-S-LNCs (AUC= 3921.391 μg/L·h, t(1/2z) = 1.294 h) compared with free DSF (AUC = 907.724 μg/L·h, t(1/2z) = 0.252 h). The in vivo distribution of S-LNCs was investigated using Cy5.5 as a fluorescent probe. In tumor-bearing mice, the delivery efficiency of S-LNCs was found to be 496.5% higher than that of free Cy5.5 and 74.5% higher than that of LNCs in tumors. In conclusion, DSF-S-LNCs increased both the stability and tumor internalization and further increased the cytotoxicity because of the higher copper content.
