Interferon-induced transmembrane protein 3 (IFITM3) is a restriction factor that can be induced by viral infection and interferons (IFNs). It inhibits the entry and replication of many viruses, which are independent of receptor usage but dependent on processes that occur in endosomes. In this study, we demonstrate that IFITM3 plays important roles in regulating the RNA-virus-triggered production of IFN-β in a negative-feedback manner. Overexpression of IFITM3 inhibited Sendai virus-triggered induction of IFN-β, whereas knockdown of IFITM3 had the opposite effect...

Peripheral blood was collected from a clinically diagnosed 64-year old male multiple schwannoma patient. Peripheral blood mononuclear cells (PBMCs) were reprogrammed with the Yamanaka KMOS reprogramming factors using the Sendai-virus reprogramming system. The transgene-free iPSC line showed pluripotency verified by immunofluorescent staining for pluripotency markers, and the iPSC line was able to differentiate into the 3 germ layers in vivo. The iPSC line also showed normal karyotype. This in vitro cellular model will be useful for further pathological studies of multiple schwannoma...

The transgene-free iPSC line showed pluripotency verified by immunofluorescent staining for pluripotency markers, and the iPSC line was able to differentiate into the 3 germ layers in vivo. The iPSC line also showed normal karyotype. This in vitro cellular model can be used to study the mechanism of sporadic Parkinson's disease and to test new drugs...

We retrieved clinical data of 13 men having herpes simplex virus (HSV)-induced non-gonococcal urethritis (NGU) without visible herpetic lesions. They visited a clinic in Sendai, Japan, between April 2013 and December 2015. All the men complained of dysuria. Meatitis was observed in 9 of the 13 men. Mononuclear cells were observed in the urethral smears from 9 men. The 13 men were treated with azithromycin or sitafloxacin regimen. First-voided urine (FVU) specimens became negative for HSV in 8 of the 10 men who returned to the clinic after antibacterial treatment, and urethritis symptoms were alleviated...

Patients with asthma experience circadian variations in their symptoms. However it remains unclear how specific aspects of this common airway disease relate to clock genes, which are critical to the generation of circadian rhythms in mammals. Here, we used a viral model of acute and chronic airway disease to examine how circadian clock disruption affects asthmatic lung phenotypes. Deletion of the core clock gene bmal1 or environmental disruption of circadian function by jet lag exacerbated acute viral bronchiolitis caused by Sendai virus (SeV) and influenza A virus in mice...

We have generated a human induced pluripotent stem cell (iPSC) line under feeder-free culture conditions using the urine derived cells (UCs) collected from subjects heterozygous for a novel Plasminogen Activator Inhibitor-1 (PAI-1) mutation. The Sendai Virus (SeV) vector encoding pluripotent Yamanaka transcription factors was used at a low multiplicity of infection to reprogram the PAI-1 UCs.

Spinocerebellar ataxia type 3 (SCA3) is a dominantly inherited neurodegenerative disease caused by a trinucleotide repeat (CAG) expansion in the coding region of ATXN3 gene resulting in production of ataxin-3 with an elongated polyglutamine tract. Here, we generated induced pluripotent stem cells (iPSCs) from the peripheral blood mononuclear cells of a male patient with SCA3 by using the Sendai-virus delivery system. The resulting iPSCs had a normal karyotype, retained the disease-causing ATXN3 mutation, expressed pluripotent markers and could differentiate into the three germ layers...

Human induced pluripotent stem (hiPS) cell lines CTRL-9-II and CTRL-10-I were derived from healthy monozygotic twin donors using non-integrating RNA based Sendai virus reprogramming and cultured in a xeno-free chemically defined condition. The established hiPS cell lines, CTRL-9-II and CTRL-10-I, are karyotypically normal, free from reprogramming vectors, display endogenously expression of pluripotency factors at levels similar to embryonic stem cells. The generated iPS cell lines demonstrate pluripotency by passing bioinformatics assay PluriTest and by embryonic body assay...

Human CMT2-FiPS4F1 cell line was generated from fibroblasts of a patient with Charcot-Marie-Tooth disease harbouring the following mutations in the GDAP1 gene in heterozygosis: p.Q163X/p.T288NfsX3. This patient did not present mutations in the PM22, MPZ or GJB genes. Human reprogramming factors OCT3/4, KLF4, SOX2 and C-MYC were delivered using a non-integrative methodology that involves the use of Sendai virus.

Human fibroblast cells collected from a 3-year old, female Rett Syndrome patient with a 32bp deletion in the X-linked MECP2 gene were obtained from the Coriell Institute. Fibroblasts were reprogrammed to iPSC cells using a Sendai-virus delivery system expressing human KOSM transcription factors. Cell-line pluripotency was demonstrated by gene expression, immunocytochemistry, in-vitro differentiation trilineage capacity and was of normal karyotype. Interestingly, subsequent clones retained the epigenetic memory of the parent fibroblasts allowing for the segregation of wild-type and mutant expressing clones...

Spinal and bulbar muscular atrophy (SBMA) is a neurodegenerative disease caused by the expansion of CAG repeats in the Androgen Receptor gene (AR). We report the generation of induced pluripotent stem cell (iPSC) lines from two SBMA patients and their healthy siblings. The SBMA and healthy iPSC lines retain the number of AR CAG repeats, express pluripotency markers and are able to differentiate into the three germ layers. The iPSC lines are also free of Sendai virus transgenes and have normal karyotypes. The SBMA iPSC lines with their sibling-matched controls would serve as useful tools to study SBMA disease mechanism...

Human somatic cells can be reprogrammed by defined factors to induced pluripotent stem cells (iPSCs). Importantly, the quality of iPSCs could impact the potential of these cells in basic and clinic research. Here, we describe a method to reprogram human fibroblast cells with Sendai virus in chemically defined conditions, to generate iPSCs that are integration-free and suitable for research and translational applications.

Amyotrophic lateral sclerosis (ALS) is a progressive and fatal degenerative disorder of motor neurons (MNs). Embryonic stem cells (ESCs)/induced pluripotent stem cells (iPSCs) now help us to understand the pathomechanisms of ALS via disease modeling. Various methods to differentiate ESCs/iPSCs into MNs by the addition of signaling molecules have been reported. However, classical methods require multiple steps, and newer simple methods using the transduction of transcription factors run the risk of genomic integration of the vector genes...
