| 1 | Macrophage-derived IL-1α promotes sterile inflammation in a mouse model of acetaminophen hepatotoxicity显示文摘The metabolic intermediate of acetaminophen(APAP)can cause severe hepatocyte necrosis,which triggers aberrant immune activation of liver non-parenchymal cells(NPC).Overzealous hepatic inflammation determines the morbidity and mortality of APAP-induced liver injury(AILI).Interleukin-1 receptor(IL-1R)signaling has been shown to play a critical role in various inflammatory conditions,but its precise role and underlying mechanism in AILI remain debatable.Herein,we show that NLRP3 inflammasome activation of IL-1βis dispensable to AILI,whereas IL-1α,the other ligand of IL-1R1,accounts for hepatic injury by a lethal dose of APAP.Furthermore,Kupffer cells function as a major source of activated IL-1αin the liver,which is activated by damaged hepatocytes through TLR4/MyD88 signaling.Finally,IL-1αis able to chemoattract and activate CD11b^(+)Gr-1^(+) myeloid cells,mostly neutrophils and inflammatory monocytes,to amplify deteriorated inflammation in the lesion.Therefore,this work identifies that MyD88-dependent activation of IL-1αin Kupffer cells plays a central role in the immunopathogenesis of AILI and implicates that IL-1αis a promising therapeutic target for AILI treatment. | Chao Zhang Jin Feng Jun Du Zhiyong Zhuo Shuo Yang Weihong Zhang Weihong Wang Shengyuan Zhang Yoichiro Iwakura Guangxun Meng Yang-Xin Fu Baidong Hou Hong Tang | 2018 | Cellular & Molecular Immunology2018，15，11： | 7 |
| 2 | Interaction between crack and twins in TMS-82 superalloy during thermomechanical fatigue process显示文摘Thermomechanical fatigue behavior of a nickel base single crystal superalloy TMS-82 has been investigated.It was found that the micropores in the alloy tend to initiate large amounts of deformation twins and the crack causes many twins to occur during its propagation.It is postulated that these twins around the micropores or the crack are induced by the stress eld of the micropores or the crack tip,respectively.A thermodynamic model is adopted linking the twin formation energy with the stress eld around the crack tip,which explains the observed results with good consistency.The in uencing factors for a crack to stimulate twins around it are shown by the model,which might provide possible ways to enhance the alloy's thermomechanical fatigue performance. | Baidong Fu Jianxin Zhang H.Harada | 2013 | Progress in Natural Science:Materials International2013，23，5： | 1 |
