Abstract
Therapeutic viral gene delivery is an emerging technology which aims to correct genetic mutations by introducing new genetic information to cells either to correct a faulty gene or to initiate cell death in oncolytic treatments. In recent years, significant scientific progress has led to several clinical trials resulting in the approval of gene therapies for human treatment. However, successful therapies remain limited due to a number of challenges such as inefficient cell uptake, low transduction efficiency (TE), limited tropism, liver toxicity and immune response. To adress these issues and increase the number of available therapies, additives from a broad range of materials like polymers, peptides, lipids, nanoparticles, and small molecules have been applied so far. The scope of this review is to highlight these selected delivery systems from a materials perspective.

Abstract
The development of gene therapy puts forward the requirements for efficient delivery of genetic information into diverse cells. However, in some cases of transfection, especially those for transfecting some primary cells and for delivering large size plasmid DNA (pDNA), the existing conventional transfection methods show poor efficiency. How to further improve transfection efficiency in these hard-to-achieve issues remains a crucial challenge. Here, we report a photothermal-assisted surface-mediated gene delivery based on a polydopamine-polyethylenimine (PDA-PEI) surface. The PDA-PEI surface was prepared through PEI-accelerated dopamine polymerization, which showed efficiency in the immobilization of PEI/pDNA polyplexes and remarkable photothermal properties. Upon IR irradiation, we observed improved transfection efficiencies of two important hard-to-achieve transfection issues, namely the transfection of primary endothelial cells, which are kinds of typical hard-to-transfect cells, and the transfection of cells with large-size pDNA. We demonstrate that the increases of transfection efficiency were due to the hyperthermia-induced pDNA release, the local cell membrane disturbance, and the polyplex internalization. This work highlights the importance of local immobilization and release of pDNA to gene deliveries, showing great potential applications in medical devices in the field of gene therapy.

Safety and efficacy evaluations of an adeno-associated virus variant for preparing IL10-secreting human neural stem cell-based therapeutics. Gene Ther 2019; 26:135-150. [PMID: 30692604 DOI: 10.1038/s41434-019-0057-8] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/22/2018] [Revised: 12/20/2018] [Accepted: 01/07/2019] [Indexed: 12/22/2022]
Abstract
Gene therapy technologies are inevitably required to boost the therapeutic performance of cell therapies; thus, validating the efficacy of gene carriers specifically used for preparing cellular therapeutics is a prerequisite for evaluating the therapeutic capabilities of gene and cell combinatorial therapies. Herein, the efficacy of a recombinant adeno-associated virus derivative (rAAVr3.45) was examined to evaluate its potential as a gene carrier for genetically manipulating interleukin-10 (IL10)-secreting human neural stem cells (hNSCs) that can potentially treat ischemic injuries or neurological disorders. Safety issues that could arise during the virus preparation or viral infection were investigated; no replication-competent AAVs were detected in the final cell suspensions, transgene expression was mostly transient, and no severe interference on endogenous gene expression by viral infection occurred. IL10 secretion from hNSCs infected by rAAVr3.45 encoding IL10 did not alter the transcriptional profile of any gene by more than threefold, but the exogenously boosted IL10 was sufficient to provoke immunomodulatory effects in an ischemic brain injury animal model, thereby accelerating the recovery of neurological deficits and the reduction of brain infarction volume. This study presents evidence that rAAVr3.45 can be potentially used as a gene carrier to prepare stem cell therapeutics.
