Journal ArticleDOI
Neutrophils are essential as a source of IL-17 in the effector phase of arthritis.
Masaki Katayama,Koichiro Ohmura,Naoichiro Yukawa,Chikashi Terao,Motomu Hashimoto,Hajime Yoshifuji,Daisuke Kawabata,Takao Fujii,Yoichiro Iwakura,Tsuneyo Mimori +9 more
TL;DR: Neutrophils are essential as a source of IL-17 in the effector phase of arthritis by using K/BxN serum-induced arthritis model, and stimulation of neutrophils with immune complex causedIL-17 secretion.
Journal ArticleDOI
Anti-U1 RNP antibodies in cerebrospinal fluid are associated with central neuropsychiatric manifestations in systemic lupus erythematosus and mixed connective tissue disease.
Takeshi Sato,Takao Fujii,Tomoko Yokoyama,Yoshimasa Fujita,Yoshitaka Imura,Naoichiro Yukawa,Daisuke Kawabata,Takaki Nojima,Koichiro Ohmura,Takashi Usui,Tsuneyo Mimori +10 more
TL;DR: The frequency of anti-U1 RNP antibodies in the CSF and the anti-RNP index are useful indicators of central NPSLE in anti- U1 R NP antibody-positive patients.
Journal ArticleDOI
Etanercept-induced anti-Jo-1-antibody-positive polymyositis in a patient with rheumatoid arthritis: a case report and review of the literature
Yuki Ishikawa,Naoichiro Yukawa,Koichiro Ohmura,Yuji Hosono,Yoshitaka Imura,Daisuke Kawabata,Takaki Nojima,Takao Fujii,Takashi Usui,Tsuneyo Mimori +9 more
TL;DR: Results suggest a relationship between the onset of PM/DM with anti-Jo-1 antibody and anti-TNF therapy for RA and recovery occurred after the cessation of anti- TNF-agent administration and CS therapy.
Journal ArticleDOI

Brown,Soumya Raychaudhuri,Fumihiko Matsuda,Hisashi Yamanaka,Yoichiro Kamatani,Kazuhiko Yamamoto +31 more
TL;DR: This study identified an independent risk of a synonymous mutation at HLA-DOA, a non-classical HLA gene, on anti-citrullinated protein autoantibody (ACPA)-positive RA risk and suggested the value of incorporating additional ancestry in MHC fine-mapping.
Journal ArticleDOI
T/NK bipotent progenitors in the thymus retain the potential to generate dendritic cells.
Hui Qing Shen,Min Lu,Tomokatsu Ikawa,Kyoko Masuda,Koichiro Ohmura,Nagahiro Minato,Yoshimoto Katsura,Yoshimoto Katsura,Hiroshi Kawamoto +8 more
TL;DR: Although the DC potential is lost with the progression of the differentiation stage, some of the T/NK bipotential progenitors still retain their DC potential even at the CD44+CD25+ stage.
