Kazuyuki Matsuda,Akira Shimada,Nao Yoshida,Atsushi Ogawa,Akihiro Watanabe,Shuhei Yajima,Susumu Iizuka,Kazutoshi Koike,Fumio Yanai,Keiichiro Kawasaki,Masakatsu Yanagimachi,Akira Kikuchi,Yoshitoshi Ohtsuka,Eiko Hidaka,Kazuyoshi Yamauchi,Miyuki Tanaka,Ryu Yanagisawa,Yozo Nakazawa,Masaaki Shiohara,Atsushi Manabe,Seiji Kojima,Kenichi Koike +21 more
TL;DR: Some children with juvenile myelomonocytic leukemia with specific RAS mutations may have spontaneously improving disease, and numbers of circulating granulocyte-macrophage progenitors were significantly reduced during the clinical course.
Journal ArticleDOI
Robust and Highly-Efficient Differentiation of Functional Monocytic Cells from Human Pluripotent Stem Cells under Serum- and Feeder Cell-Free Conditions
Masakatsu Yanagimachi,Masakatsu Yanagimachi,Akira Niwa,Takayuki Tanaka,Fumiko Honda-Ozaki,Seiko Nishimoto,Yuuki Murata,Takahiro Yasumi,Jun Ito,Shota Tomida,Koichi Oshima,Isao Asaka,Hiroaki Goto,Toshio Heike,Tatsutoshi Nakahata,Megumu K. Saito +15 more
TL;DR: A robust and highly-efficient method to differentiate functional monocytic cells from ESCs/iPSCs under serum- and feeder cell-free conditions is established and should be useful for regenerative medicine, disease-specific iPSC studies and drug discovery.
Journal ArticleDOI
Association of IRF5 polymorphisms with susceptibility to macrophage activation syndrome in patients with juvenile idiopathic arthritis.
Masakatsu Yanagimachi,Takuya Naruto,Takako Miyamae,Takuma Hara,Masako Kikuchi,Ryoki Hara,Tomoyuki Imagawa,Masaaki Mori,Hidenori Sato,Hiroaki Goto,Shumpei Yokota +10 more
TL;DR: IRF5 gene polymorphism is a genetic factor influencing susceptibility to MAS in patients with systemic JIA, and IRF5 contributes to the pathogenesis of MAS in these patients.
Journal ArticleDOI
Influence of CYP3A5 and ABCB1 gene polymorphisms on calcineurin inhibitor-related neurotoxicity after hematopoietic stem cell transplantation.
Masakatsu Yanagimachi,Takuya Naruto,Reo Tanoshima,Hiromi Kato,Tomoko Yokosuka,Ryosuke Kajiwara,Hisaki Fujii,Fumiko Tanaka,Hiroaki Goto,Tatsuhiko Yagihashi,Kenjiro Kosaki,Shumpei Yokota +11 more
TL;DR: Yanagimachi et al. as mentioned in this paper found that genetic variability in CYP3A5 and ABCB1 genes may be associated with CNI-related neurotoxicity after hematopoietic stem cell transplant.
Journal ArticleDOI
Influence of polymorphisms within the methotrexate pathway genes on the toxicity and efficacy of methotrexate in patients with juvenile idiopathic arthritis.
Masakatsu Yanagimachi,Takuya Naruto,Takuma Hara,Masako Kikuchi,Ryoki Hara,Takako Miyamae,Tomoyuki Imagawa,Masaaki Mori,Tetsuji Kaneko,Satoshi Morita,Hiroaki Goto,Shumpei Yokota +11 more
TL;DR: The non-TT genotype at GGH T16C was associated with a high risk of liver dysfunction, presumably because the C allele of GGH C16T may reduce the activity of G GH, and the time interval before MTX treatment and rheumatoid factor positivity were associated with the efficacy ofMTX treatment.
