'Ischemic tolerance' phenomenon found in the brain
Kazuo Kitagawa,Masayasu Matsumoto,Masafumi Tagaya,Ryuji Hata,Hirokazu Ueda,Michio Niinobe,Nobuo Handa,Ryuzo Fukunaga,Kazufumi Kimura,Katsuhiko Mikoshiba,Takenobu Kamada +10 more
TL;DR: 'ischemic tolerance' phenomenon induced by ischemic stress--which is unquestionably important--and frequent stress in clinical medicine, is intriguing and may open a new approach to investigate the pathophysiology of isChemic neuronal damage.
Journal ArticleDOI
Modeling Alzheimer’s Disease with iPSCs Reveals Stress Phenotypes Associated with Intracellular Aβ and Differential Drug Responsiveness
Takayuki Kondo,Masashi Asai,Masashi Asai,Kayoko Tsukita,Yumiko Kutoku,Yutaka Ohsawa,Yoshihide Sunada,Keiko Imamura,Naohiro Egawa,Naoki Yahata,Keisuke Okita,Kazutoshi Takahashi,Isao Asaka,Takashi Aoi,Akira Watanabe,Kaori Watanabe,Chie Kadoya,Rie Nakano,Dai Watanabe,Kei Maruyama,Osamu Hori,Satoshi Hibino,Tominari Choshi,Tatsutoshi Nakahata,Hiroyuki Hioki,Takeshi Kaneko,Motoko Naitoh,Katsuhiro Yoshikawa,Satoko Yamawaki,Shigehiko Suzuki,Ryuji Hata,Shu-ichi Ueno,Tsuneyoshi Seki,Kazuhiro Kobayashi,Tatsushi Toda,Kazuma Murakami,Kazuhiro Irie,William L. Klein,Hiroshi Mori,Takashi Asada,Ryosuke Takahashi,Nobuhisa Iwata,Shinya Yamanaka,Haruhisa Inoue +43 more
TL;DR: Differential manifestation of ER stress and DHA responsiveness may help explain variable clinical results obtained with the use of DHA treatment and suggests that DHA may in fact be effective for a subset of patients.
Journal ArticleDOI
‘Ischemic tolerance’ phenomenon detected in various brain regions
Kazuo Kitagawa,Masayasu Matsumoto,Keisuke Kuwabara,Masafumi Tagaya,Toshiho Ohtsuki,Ryuji Hata,Hirokazu Ueda,Nobou Handa,Kazufumi Kimura,Takenobu Kamada +9 more
TL;DR: The present study demonstrated that the 'ischemic tolerance' phenomenon was widely found in the brain and suggested that ischemic treatment severe enough to cause HSP 72 synthesis might be needed for induction of 'iscemic tolerance'.
Journal ArticleDOI
Microtubule-associated protein 2 as a sensitive marker for cerebral ischemic damage--immunohistochemical investigation of dendritic damage.
Kazuo Kitagawa,Masayasu Matsumoto,Michio Niinobe,Katsuhiko Mikoshiba,Ryuji Hata,Hirokazu Ueda,Nobuo Handa,Ryuzo Fukunaga,Yoshinari Isaka,Kazufumi Kimura,Takenobu Kamada +10 more
TL;DR: The present investigation suggests that dendrites in the vulnerable regions may be quite susceptible to ischemic stress and that the immunohistochemical procedure for microtubule-associated protein 2 may be very useful for demonstration of dendritic damage in various pathophysiological states of the central nervous system.
Journal ArticleDOI
A reproducible model of middle cerebral artery occlusion in mice : Hemodynamic, biochemical, and magnetic resonance imaging
Ryuji Hata,Günter Mies,Christoph Wiessner,Klaus Fritze,Daniel Hesselbarth,Gerrit Brinker,Konstantin-Alexander Hossmann +6 more
TL;DR: The use of multiparametric imaging techniques in this improved MCA occlusion model opens the way for advanced pathophysiological studies of stroke in gene-manipulated animals and demonstrates the feasibility of dynamic evaluations of infarct evolution.
