Journal ArticleDOI
Toll-like receptor 4 signalling through MyD88 is essential to control Salmonella enterica serovar typhimurium infection, but not for the initiation of bacterial clearance.
Suzanne Talbot,Sabine Tötemeyer,Sabine Tötemeyer,Masahiro Yamamoto,Shizuo Akira,Katherine Hughes,David Gray,Tom A. Barr,Pietro Mastroeni,Duncan J. Maskell,Clare E. Bryant +10 more
TL;DR: It is shown that TLR4 and MyD88, but not Mal or TRIF, are essential for the control of exponential S. Typhimurium growth, suggesting thatTLR4 signalling is not important in driving bacterial clearance in comparison to its critical role in controlling early bacterial growth in mouse typhoid.
Journal ArticleDOI
Roles of Stat3 and ERK in G‐CSF Signaling
Kenjirou Kamezaki,Kazuya Shimoda,Akihiko Numata,Takashi Haro,Haruko Kakumitsu,Masumi Yoshie,Masahiro Yamamoto,Kiyoshi Takeda,Tadashi Matsuda,Shizuo Akira,Katsuhiro Ogawa,Mine Harada +11 more
TL;DR: Results indicate that Stat3 functions as a negative regulator of G‐ CSF signaling by inducing SOCS3 expression and that ERK activation is the major factor responsible for inducing the proliferation of hematopoietic cells in response to G‐CSF.
Journal ArticleDOI
Activation of Lipopolysaccharide–TLR4 Signaling Accelerates the Ototoxic Potential of Cisplatin in Mice
Gi-Su Oh,Hyung-Jin Kim,Jae-Hyuck Choi,AiHua Shen,Chang-Hoi Kim,Se-Jin Kim,Sae-Ron Shin,Seung-Heon Hong,Yunha Kim,Channy Park,Sung Joong Lee,Shizuo Akira,Raekil Park,Hong-Seob So +13 more
TL;DR: Cisplatin-induced TLR4 expression and its binding to LPS in mouse cochlear tissues and the effect of this interaction on hearing function are investigated to suggest that hearing function can be easily damaged by increased TLR expression and microbial infections due to the weakened host defense systems of cancer patients receiving therapy.
Journal ArticleDOI
VP1686, a Vibrio Type III Secretion Protein, Induces Toll-like Receptor-independent Apoptosis in Macrophage through NF-κB Inhibition
Rabindra N. Bhattacharjee,Kwon-Sam Park,Kwon-Sam Park,Yutaro Kumagai,Kazuhisa Okada,Masahiro Yamamoto,Satoshi Uematsu,Kosuke Matsui,Himanshu Kumar,Taro Kawai,Tetsuya Iida,Takeshi Honda,Osamu Takeuchi,Osamu Takeuchi,Shizuo Akira,Shizuo Akira +15 more
TL;DR: It is established that TTSS1-dependent secretion and translocation of a V. parahaemolyticus effector protein VP1686 into the cytosol induces DNA fragmentation in macrophages, and an important role is suggested for Vibrio effectorproteinVP1686 that activate a conserved apoptotic pathway in Macrophages through suppression of NF-κB activation independent of Toll-like receptor signaling.
Journal ArticleDOI
Synergistic effects of lipopolysaccharide and interferon-γ in inducing interleukin-8 production in human monocytic THP-1 cells is accompanied by up-regulation of CD14, Toll-like receptor 4, MD-2 and MyD88 expression
TL;DR: Combined stimulation of THP-1 cells with LPS and IFN-γ up-regulate mCD14, TLR4, MD-2 and MyD88 expression by these cells, which might be involved in synergistic IL-8 production by the cells.
