Loss of autophagy in the central nervous system causes neurodegeneration in mice
Masaaki Komatsu,Satoshi Waguri,Satoshi Waguri,Tomoki Chiba,Shigeo Murata,Junichi Iwata,Junichi Iwata,Isei Tanida,Takashi Ueno,Masato Koike,Yasuo Uchiyama,Eiki Kominami,Keiji Tanaka +12 more
TL;DR: It is found that mice lacking Atg7 specifically in the central nervous system showed behavioural defects, including abnormal limb-clasping reflexes and a reduction in coordinated movement, and died within 28 weeks of birth, and that impairment of autophagy is implicated in the pathogenesis of neurodegenerative disorders involving ubiquitin-containing inclusion bodies.
Journal ArticleDOI
Impairment of starvation-induced and constitutive autophagy in Atg7-deficient mice
Masaaki Komatsu,Satoshi Waguri,Takashi Ueno,Junichi Iwata,Shigeo Murata,Isei Tanida,Junji Ezaki,Noboru Mizushima,Yoshinori Ohsumi,Yasuo Uchiyama,Eiki Kominami,Keiji Tanaka,Tomoki Chiba +12 more
TL;DR: Conditional knockout mice of Atg7 were generated and showed the important role of autophagy in starvation response and the quality control of proteins and organelles in quiescent cells.
Journal ArticleDOI
Homeostatic Levels of p62 Control Cytoplasmic Inclusion Body Formation in Autophagy-Deficient Mice
Masaaki Komatsu,Satoshi Waguri,Masato Koike,Yu-shin Sou,Yu-shin Sou,Takashi Ueno,Taichi Hara,Noboru Mizushima,Junichi Iwata,Junichi Iwata,Junji Ezaki,Shigeo Murata,Jun Hamazaki,Yasumasa Nishito,Shun-ichiro Iemura,Tohru Natsume,Toru Yanagawa,Junya Uwayama,Eiji Warabi,Hiroshi Yoshida,Tetsuro Ishii,Akira Kobayashi,Masayuki Yamamoto,Zhenyu Yue,Yasuo Uchiyama,Eiki Kominami,Keiji Tanaka +26 more
TL;DR: The findings highlight the unexpected role of homeostatic level of p62, which is regulated by autophagy, in controlling intracellular inclusion body formation, and indicate that the pathologic process associated with autophagic deficiency is cell-type specific.
Journal ArticleDOI
T-cell-mediated regulation of osteoclastogenesis by signalling cross-talk between RANKL and IFN-gamma.

TL;DR: This study shows that there is cross-talk between the tumour necrosis factor and IFN families of cytokines, through which IFN-γ provides a negative link between T-cell activation and bone resorption and may offer a therapeutic approach to treat the inflammation-induced tissue breakdown.
Journal ArticleDOI
Involvement of linear polyubiquitylation of NEMO in NF-kappaB activation.
Fuminori Tokunaga,Shin-ichi Sakata,Shin-ichi Sakata,Yasushi Saeki,Yoshinori Satomi,Takayoshi Kirisako,Kiyoko Kamei,Kiyoko Kamei,Tomoko Nakagawa,Tomoko Nakagawa,Michiko Kato,Shigeo Murata,Shigeo Murata,Shoji Yamaoka,Masahiro Yamamoto,Shizuo Akira,Toshifumi Takao,Keiji Tanaka,Kazuhiro Iwai,Kazuhiro Iwai +19 more
TL;DR: Results indicate that LUBAC is involved in the physiological regulation of the canonical NF-κB activation pathway through linear polyubiquitylation of NEMO.
