| 1 | BLT1 in dendritic cells promotes Th1/Th17 differentiation and its deficiency ameliorates TNBS-induced colitis显示文摘Leukotriene B4(LTB4)synthesis is enhanced in the colonic mucosa in patients with inflammatory bowel disease(IBD).BLT1,a highaffinity receptor for LTB4,exhibits no effect on the progression of dextran sodium sulfate(DSS)-induced colitis,which mostly relies on innate immunity.Here,we reported that BLT1 regulates trinitrobenzene sulfonic acid(TNBS)-induced colitis,which reflects CD4+T-cell-dependent adaptive immune mechanisms of IBD.We found that BLT1 signaling enhanced the progression of colitis through controlling the production of proinflammatory cytokines by dendritic cells(DCs)and modulating the differentiation of Th1 and Th17.BLT1−/−mice displayed an alleviated severity of TNBS-induced colitis with reduced body weight loss and infiltrating cells in the lamina propria.BLT1 deficiency in DCs led to reduced production of proinflammatory cytokines,including IL-6,TNF-α,and IL-12,and these results were further confirmed via treatment with a BLT1 antagonist.The impaired cytokine production by BLT1−/−DCs subsequently led to reduced Th1 and Th17 differentiation both in vitro and in vivo.We further performed a conditional DC reconstitution experiment to assess whether BLT1 in DCs plays a major role in regulating the pathogenesis of TNBS-induced colitis,and the results indicate that BLT1 deficiency in DCs also significantly reduces disease severity.The mechanistic study demonstrated that BLT1-regulated proinflammatory cytokine production through the Gαiβγsubunit-phospholipase Cβ(PLCβ)-PKC pathway.Notably,we found that treatment with the BLT1 antagonist also reduced the production of proinflammatory cytokines by human peripheral blood DCs.Our findings reveal the critical role of BLT1 in regulating adaptive immunity and TNBS-induced colitis,which further supports BLT1 as a potential drug target for adaptive immunity-mediated IBD. | Jinfeng Zhou Weiming Lai Wanjie Yang Juping Pan Hu Shen Yingying Cai Cuixia Yang Ningjia Ma Yue Zhang Ru Zhang Xin Xie Zhongjun Dong Yuan Gao Changsheng Du | 2018 | Cellular & Molecular Immunology2018，15，12： | 9 |
| 2 | High-Performance Natural Melanin/Poly(vinyl Alcohol-co-ethylene) Nanofibers/PA6 Fiber for Twisted and Coiled Fiber-Based Actuator显示文摘Twisted and coiled fiber-based actuators have drawn a great attention because their unique structure can provide mechanical response with the external thermal stimulus.Herein,an ultra-fast and light-weight twisted and coiled fiber-based actuator was designed based on a nature melanin/poly(vinyl alcohol-co-ethylene)(PVA-co-PE)nanofibers/PA6 composite fiber.In brief,PA6 was firstly coated by melanin/PVA-co-PE nanofibers using a spraying method,followed by the twisting and coat-ing the composite fiber to obtain the actuator.The excellent photothermal property of melanin contributed to the superior performance of the actuator,whereas the PVA-co-PE nanofibers was responsible for the uniform distribution of melanin and the enhanced mechanical property of the prepared-actuator.This unique design has led to the high performance of the melanin/NFs/PA6 fiber-based actuator,whose torsion actuation can reach to 14,000 rpm,and maximum tensile actuation was−6.36%at temperature difference of 40℃.In addition,the tensile stress of PA6/NFs/melanin fiber was about four times higher than PA6 filaments.Owing to the simple and environmental-benign preparation method,as well as the excellent effi-ciency of twisted and coiled melanin/NFs/PA6 fiber-based actuator,this study highlights the facile design of the composite fiber for high-performance fiber-based actuators.This fiber-based actuator is promising for application in energy generator. | Jiahui Chen Esfandiar Pakdel Wanjie Xie Lu Sun Mengyuan Xu Qiongzhen Liu Dong Wang | 2020 | Advanced Fiber Materials2020，2，2： | 0 |
| 3 | Dietary ribose supplementation improves flesh quality through purine metabolism in gibel carp(Carassius auratus gibelio)显示文摘Since the aquaculture industry is currently observing a deterioration in the flesh quality of farmed fish,the use of nutrients as additives to improve the flesh quality of farmed fish species is a viable strategy.The aim of this study was to investigate the effect of dietary D-ribose(RI)on the nutritional value,texture and flavour of gibel carp(Carassius auratus gibelio).Four diets were formulated containing exogenous RI at 4 gradient levels:0(Control),0.15%(0.15RI),0.30%(0.30RI)and 0.45%(0.45RI).A total of 240 fish(150±0.31 g)were randomly distributed into 12 fibreglass tanks(150 L per tank).Triplicate tanks were randomly assigned to each diet.The feeding trial was carried out in an indoor recirculating aquaculture system for 60 d.After the feeding trial,the muscle and liver of gibel carp were analysed.The results showed that RI supplementation did not result in any negative impact on the growth performance and 0.30RI supplementation significantly increased the whole-body protein content compared to the control group.The contents of collagen and glycogen in muscle were enhanced by RI supplementation.The alterations in the flesh indicated that RI supplementation improved the texture of the flesh in terms of its water-holding capacity and hardness,therefore improving the taste.Dietary RI facilitated the deposition of amino acids and fatty acids in the muscle that contributed to the meaty taste and nutritional value.Furthermore,a combination of metabolomics and expression of key genes in liver and muscle revealed that 0.30RI activated the purine metabolism pathways by supplementing the substrate for nucleotide synthesis and thereby promoting the deposition of flavour substance in flesh.This study offers a new approach for providing healthy,nutritious and flavourful aquatic products. | Wanjie Cai Lele Fu Cui Liu Linyue He Haokun Liu Dong Han Xiaoming Zhu Yunxia Yang Junyan Jin Shouqi Xie | 2023 | Animal Nutrition2023，，2： | 0 |
