This leads to skeletal and cardiorespiratory disease with severe neurodegeneration in two thirds of sufferers. Enzyme replacement therapy is ineffective at treating neurological disease, as intravenously delivered IDS is unable to cross the blood-brain barrier (BBB). Hematopoietic stem cell transplant is also unsuccessful, presumably due to insufficient IDS enzyme production from transplanted cells engrafting in the brain. We used two different peptide sequences (rabies virus glycoprotein [RVG] and gh625), both previously published as BBB-crossing peptides, fused to IDS and delivered via hematopoietic stem cell gene therapy (HSCGT). HSCGT with LV.IDS.RVG and LV.IDS.gh625 was compared with LV.IDS.ApoEII and LV.IDS in MPS II mice at 6 months post-transplant. Levels of IDS enzyme activity in the brain and peripheral tissues were lower in LV.IDS.RVG- and LV.IDS.gh625-treated mice than in LV.IDS.ApoEII- and LV.IDS-treated mice, despite comparable vector copy numbers. Microgliosis, astrocytosis, and lysosomal swelling were partially normalized in MPS II mice treated with LV.IDS.RVG and LV.IDS.gh625. Skeletal thickening was normalized by both treatments to wild-type levels. Although reductions in skeletal abnormalities and neuropathology are encouraging, given the low levels of enzyme activity compared with control tissue from LV.IDS- and LV.IDS.ApoEII-transplanted mice, the RVG and gh625 peptides are unlikely to be ideal candidates for HSCGT in MPS II and are inferior to the ApoEII peptide that we have previously demonstrated to be more effective at correcting MPS II disease than IDS alone.</p>","PeriodicalId":13007,"journal":{"name":"Human gene therapy","volume":" ","pages":"232-242"},"PeriodicalIF":3.9,"publicationDate":"2024-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9754730","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

But it is limited in its effectiveness. In this study, we used combination therapy with immune checkpoint inhibitor to enhance the antitumor efficacy of OVs. Using reverse genetics technology, we rescued an oncolytic influenza virus with the name delNS1-GM-CSF from the virus. After identifying the hemagglutination and 50% tissue culture infectivedose (TCID₅₀) of delNS1-GM-CSF, it was purified, and the viral morphology was observed under electron microscopy. Reverse transcription quantitative-polymerase chain reaction (RT-qPCR) was used to identify the level of GM-CSF expression in delNS1-GM-CSF, and the GM-CSF expression level was determined after infection with delNS1-GM-CSF by enzyme linked immunosorbent assay (ELISA). To study the tumor-killing effect of delNS1-GM-CSF, we utilized the hepatocellular carcinoma (HCC) tumor-bearing mouse model. To examine signaling pathways, we performed transcriptome sequencing on mouse tumor tissue and applied western blotting to confirm the results. Changes in T-cell infiltration in HCC tumors following treatment were analyzed using flow cytometry and immunohistochemistry. DelNS1-GM-CSF can target and kill HCCs without damaging normal hepatocytes. DelNS1-GM-CSF combined with programmed cell death 1 blockade therapy enhanced anti-tumor effects and significantly improved mouse survival. Further, we found that combination therapy had an antitumor impact via the janus kinase-signal transducer and activator of transcription (JAK2-STAT3) pathway as well as activated CD4+ and CD8+T cells. Interestingly, combined therapy also showed promising efficacy in distant tumors. DelNS1-GM-CSF is well targeted. Mechanistic investigation revealed that it functions through the JAK2-STAT3 pathway.

Accumulation of glycosphingolipids, mainly globotriaosylceramide (Gb3) in tissues, induces cellular dysfunction leading to multi-organ disorder. Gene therapy is a promising strategy that can overcome these problems, and virus vectors such as adeno-associated virus (AAV) have been used for study on gene therapy. We used human Gb3 synthetase-transgenic (TgG3S)/α-Gal A knockout (GLAko) mice. TgG3S/GLAko mice have elevated Gb3 accumulation in the major organs compared with GLAko mice, which have been widely used as a model for FD. At the age of 6 weeks, male TgG3S/GLAko were injected with 2 × 10¹² vector genome AAV9 vectors containing human α-Gal A cDNA. Eight weeks after intravenous injection of AAV, α-Gal A enzymatic activity was elevated in the plasma, heart, and liver of TgG3S/GLAko mice to levels corresponding to 224%, 293%, and 105% of wild-type, respectively. Gb3 amount 8 weeks after AAV injection in the heart and liver of this group was successfully reduced to levels corresponding to 16% and 3% of untreated TgG3S/GLAko mice. Although the brain and kidney of AAV9-treated TgG3S/GLAko mice showed no significant increases in α-Gal A activity, Gb3 amount was smaller than untreated littermates (48% and 44%, respectively). In this study, systemic AAV administration did not show significant extension of the lifespan of TgG3S/GLAko mice compared with the untreated littermates.

Human adenoviruses (HAdVs) have been at the forefront of gene delivery for many years, and the subject of intensive development resulting in several generations of agents, including replication-competent, -defective or retargeted vectors, and recently also helper-dependent (HD), so-called gutless vectors lacking any viral protein coding information. While it is possible to produce HD-AdVs in significant amounts, physical properties of these virus-like particles and their efficiency of transduction have not been addressed. Here, we used single-cell and single virus particle assays to probe the effect of genome length on HAdV-C5 vector transduction. Our results demonstrate that first-generation C5 vectors lacking the E1/E3 regions of the viral genome as well as HD-AdV-C5 particles with a wild type (wt) ∼36 kbp or an undersized double-strand DNA genome are similar to human adenovirus C5 (HAdV-C5) wt regarding attachment to human lung epithelial cells, endocytic uptake, endosome penetration and dependency on the E3 RING ubiquitin ligase Mind Bomb 1 for DNA uncoating at the nuclear pore complex. Atomic force microscopy measurements of single virus particles indicated that small changes in the genome length from 94% to 103% of HAdV-C5 have no major impact on physical and mechanical features of AdV vectors. In contrast, an HD-AdV-C5 with ∼30 kbp genome was slightly stiffer and less heat-resistant than the other particles, despite comparable entry and transduction efficiencies in tissue culture cell lines, including murine alveolar macrophage-like Max-Planck-Institute (MPI)-2 cells. Together, our <i>in vitro</i> studies reinforce the use of HD-AdV vectors for effective single round gene delivery.
