Induction of interferons (IFNs) is a central event of antiviral innate immunity. As crucial post-transcriptional regulators, microRNAs (miRNAs) are important for IFN-mediated host defense. Although screening has indicated a substantial number of miRNAs to be differentially expressed after IFN stimulation, the detailed mechanisms of these miRNAs in the antiviral response is underexplored and of great significance. Here, we show that hsa-miR-1225-3p is specifically downregulated by type I IFN through IFN/JAK/STAT signaling pathway...

Fibroblasts were isolated from a skin biopsy of a clinically diagnosed 51-year-old female attention-deficit/hyperactivity disorder (ADHD) patient carrying a duplication of SLC2A3, a gene encoding neuronal glucose transporter-3 (GLUT3). Patient fibroblasts were infected with Sendai virus, a single-stranded RNA virus, to generate transgene-free human induced pluripotent stem cells (iPSCs). SLC2A3-D2-iPSCs showed expression of pluripotency-associated markers, were able to differentiate into cells of the three germ layers in vitro and had a normal female karyotype...

Spinocerebellar ataxia type 3 (SCA3) is a dominantly inherited neurodegenerative disease caused by a CAG repeat expansion in the region of the ATXN3 gene. The main feature of SCA3 is progressive ataxia, which affects balance, gait, and speech. Urine cells (UCs) of a SCA3 patient were successfully translated to induced pluripotent stem cells (iPSCs) by using the Sendai virus delivery system. ZZUi004-A cell line may provide a robust platform for further study of SCA3 pathogenesis as well as drug testing and gene therapy research...

Virus infection induces the production of type I interferons (IFNs). IFNs bind to their heterodimeric receptors to initiate downstream cascade of signaling, leading to the up-regulation of interferon-stimulated genes (ISGs). ISGs play very important roles in innate immunity through a variety of mechanisms. Although hundreds of ISGs have been identified, it is commonly recognized that more ISGs await to be discovered. The aim of this study was to identify new ISGs and to probe their roles in regulating virus-induced type I IFN production...

Pluripotent stem cell derived human neuronal progenitor cells (hPSC-NPCs) and their mature neuronal cell culture derivatives may efficiently be used for central nervous system (CNS) drug screening, including the investigation of ligand-induced calcium signalization. We have established hippocampal NPC cultures derived from human induced PSCs, which were previously generated by non-integrating Sendai virus reprogramming. Using established protocols these NPCs were differentiated into hippocampal dentate gyrus neurons...

Sialidosis is a rare autosomal recessive disorder that affects the intralysosomal catabolism of sialylated glycoconjugates and is involved in cellular immune response. Mutations in NEU1, which encodes the sialidase enzyme, result in sialidosis. Sialidosis is characterized by the progressive lysosomal storage of sialylated glycopeptides and oligosaccharides. In this study, we used Sendai virus reprogramming to generate an induced pluripotent stem cell (iPSC) line carrying the A544G mutation combined with the 667-679 deletion of the NEU1 gene from a sialidosis patient...

Leucine rich repeat kinase (LRRK2) is the most prevalent genetic cause for Parkinson's disease. LRRK2 p.G2385R is an Asian specific genetic risk factor for sporadic Parkinson's disease. We generated two induced pluripotent stem cells (iPSCs), IBMS-iPSC-018-09 and IBMS-iPSC-020-01, from the peripheral blood mononuclear cells of two patients carrying LRRK2 p.G2385R variant by using the Sendai-virus delivery system. These iPSCs had a normal karyotype and exhibited pluripotency, such as an embryonic stem cell-like morphology, expression of pluripotent markers, and capacity to differentiate into three germ layers...

BACKGROUND AND AIMS: Most viruses are detected at early stages of cell infection and induce an innate immune response mediated by production interferons (IFNs). IFNs induce expression of hundreds of IFN-stimulated genes (ISGs). Infection of chimpanzees with hepatitis C virus, but not hepatitis B virus (HBV), induces ISG expression in the liver. HBV might not induce an innate immune response because it is not detected by pattern recognition receptors (the stealth properties of HBV) or because HBV suppresses IFN production or signaling despite detection by pattern recognition receptors...

The interferon (IFN) system represents the first line of defense against a wide range of viruses. Virus infection rapidly triggers the transcriptional induction of IFN-β and IFN Stimulated Genes (ISGs), whose protein products act as viral restriction factors by interfering with specific stages of virus life cycle, such as entry, transcription, translation, genome replication, assembly and egress. Here, we report a new mode of action of an ISG, IFN-induced TDRD7 (tudor domain containing 7) inhibited paramyxovirus replication by inhibiting autophagy...

BACKGROUND: Runt-related transcription factor 2 (RUNX2) haploinsufficiency causes cleidocranial dysplasia (CCD) which is characterized by supernumerary teeth, short stature, clavicular dysplasia, and osteoporosis. At present, as a therapeutic strategy for osteoporosis, mesenchymal stem cell (MSC) transplantation therapy is performed in addition to drug therapy. However, MSC-based therapy for osteoporosis in CCD patients is difficult due to a reduction in the ability of MSCs to differentiate into osteoblasts resulting from impaired RUNX2 function...

Mutations in the PARK2 gene, which encodes PARKIN, are the most frequent cause of autosomal recessive Parkinson's disease (PD). We report the generation of an induced pluripotent stem cell (iPSC) line from a 78-year-old patient carrying a compound heterozygous mutation (c.823C>T and EX6del) in the PARK2 gene. Skin fibroblasts were reprogrammed using the non-integrating Sendai virus technology to deliver OCT3/4, SOX2, c-MYC and KLF4 factors. The generated cell line CSC-44 exhibits expression of common pluripotency markers, in vitro differentiation into the three germ layers and normal karyotype...

An induced pluripotent stem cell (iPSC) line was generated from a 36-year-old patient with sporadic Parkinson's disease (PD). Skin fibroblasts were reprogrammed using the non-integrating Sendai virus technology to deliver OCT3/4, SOX2, c-MYC and KLF4 factors. The generated cell line (CSC-43) exhibits expression of common pluripotency markers, in vitro differentiation into three germ layers and normal karyotype. This iPSC line can be used to study the mechanisms underlying the development of PD.

Skin fibroblasts were collected from a 44-year-old patient with sporadic case of Parkinson's disease (PD). The non-integrating Sendai virus vector encoding OCT3/4, SOX2, c-MYC and KLF4 was used to reprogram fibroblasts into induced pluripotent stem cells (iPSCs). Generated iPSCs had normal karyotypes, expressed common stem cell markers, and were capable of differentiating into all three germ layers. Generated line could be used for PD modeling to understand the mechanisms that influence the disorder.

Paramyxovirus V proteins are known antagonists of the RIG-I-like receptor (RLR)-mediated interferon induction pathway, interacting with and inhibiting the RLR MDA5. We report interactions between the Nipah virus V protein and both the RIG-I regulatory protein, TRIM25, and RIG-I. We also observed interactions between these host proteins and the V proteins of measles virus, Sendai virus and parainfluenza virus. These interactions are mediated by the conserved C-terminal domain of the V protein, which binds to the tandem CARDs of RIG-I (the region of TRIM25-ubiquitination) and to the SPRY domain of TRIM25, which mediates TRIM25 interaction with the RIG-I CARDs...

Skin fibroblasts were obtained from a 42-year-old Alzheimer's disease (AD) patient carrying mutations in the PSEN1 gene. An iPSC line was successfully established using the Sendai-virus (SeV) delivery system. The patient-specific iPSCs were free of genomically integrated reprogramming genes, had the specific mutation, expressed the expected pluripotency markers, and had the potential to differentiate into cells of all three germ layers. Our model might offer a robust platform for further study of the pathomechanism of this disease as well as drug testing and gene therapy studies...
