  1. Hayashi M, Nakashima T, Yoshimura N, Okamoto K, Tanaka S, Takayanagi H. Autoregulation of Osteocyte Sema3A Orchestrates Estrogen Action and Counteracts Bone Aging. Cell Metab. 2019;: pubmed publisher
    ..We further show that serum levels of SEMA3A decreased with age or after menopause in humans. Thus, we provide a mechanistic insight into the estrogen action and a promising therapeutic approach to protect against bone-related aging. ..
  2. Inoue M, Okamoto K, Terashima A, Nitta T, Muro R, Negishi Koga T, et al. Arginine methylation controls the strength of γc-family cytokine signaling in T cell maintenance. Nat Immunol. 2018;: pubmed publisher
    ..Thus, arginine methylation regulates strength of signaling via γc-family cytokines by facilitating the expression of signal-transducing components. ..

  4. Komatsu N, Takayanagi H. Arthritogenic T cells in autoimmune arthritis. Int J Biochem Cell Biol. 2015;58:92-6 pubmed publisher
    ..Further analysis on the molecular basis and antigen-specificity of arthritogenic Th17 cell subsets will be helpful to establish novel therapeutic approaches and clarify how self-tolerance breaks down in autoimmune arthritis. ..
  5. Komatsu N, Takayanagi H. Regulatory T cells in Arthritis. Prog Mol Biol Transl Sci. 2015;136:207-15 pubmed publisher
    ..Here, we summarize our understanding of the role of Treg cells in arthritis based on recent human and murine studies. ..

    ..Thus, two independent factors, Fezf2 and Aire, permit the expression of TRAs in the thymus to ensure immune tolerance. ..
  9. Ono T, Takayanagi H. Osteoimmunology in Bone Fracture Healing. Curr Osteoporos Rep. 2017;15:367-375 pubmed publisher
    ..Accumulating evidence has begun to reveal the deeper picture of bone fracture healing. Further studies are required for the development of novel therapeutic strategies for bone fracture. ..

  1. Nitta T, Kochi Y, Muro R, Tomofuji Y, Okamura T, Murata S, et al. Human thymoproteasome variations influence CD8 T cell selection. Sci Immunol. 2017;2: pubmed publisher
    ..Our findings suggest that, in addition to the MHC haplotype, proteasome variations influence T cell repertoire selection and may contribute to the difference in individual susceptibility to autoimmunity. ..
  2. Takaba H, Takayanagi H. The Mechanisms of T Cell Selection in the Thymus. Trends Immunol. 2017;38:805-816 pubmed publisher
    ..Here, we discuss novel findings on the transcriptional mechanisms of tissue restricted-antigen expression in the medullary thymic epithelial cells and its effects on T cell selection. ..
  3. Tsukasaki M, Komatsu N, Nagashima K, Nitta T, Pluemsakunthai W, Shukunami C, et al. Host defense against oral microbiota by bone-damaging T cells. Nat Commun. 2018;9:701 pubmed publisher
    ..Thus, bone-damaging T cells, which may have developed to stop local infection by inducing tooth loss, function as a double-edged sword by protecting against pathogens while also inducing skeletal tissue degradation. ..
