| 1 | NLRP3-dependent pyroptosis is required for HIV-1 gp120- induced neuropathology显示文摘The human immunodeficiency virus-1(HIV-1)envelope protein gp120 is the major contributor to the pathogenesis of HIVassociated neurocognitive disorder(HAND).Neuroinflammation plays a pivotal role in gp120-induced neuropathology,but how gp120 triggers neuroinflammatory processes and subsequent neuronal death remains unknown.Here,we provide evidence that NLRP3 is required for gp120-induced neuroinflammation and neuropathy.Our results showed that gp120-induced NLRP3-dependent pyroptosis and IL-1βproduction in microglia.Inhibition of microglial NLRP3 inflammasome activation alleviated gp120-mediated neuroinflammatory factor release and neuronal injury.Importantly,we showed that chronic administration of MCC950,a novel selective NLRP3 inhibitor,to gp120 transgenic mice not only attenuated neuroinflammation and neuronal death but also promoted neuronal regeneration and restored the impaired neurocognitive function.In conclusion,our data revealed that the NLRP3 inflammasome is important for gp120-induced neuroinflammation and neuropathology and suggest that NLRP3 is a potential novel target for the treatment of HAND. | Xiaolong He Weijun Yang Zhijie Zeng Yi Wei Jie Gao Bao Zhang Li Li Liqun Liu Yu Wan Qing Zeng Zelong Gong Liting Liu Hanyun Zhang Yubin Li Shaojie Yang Tongtong Hu Lixian Wu Eliezer Masliah Shenghe Huang Hong Cao | 2020 | Cellular & Molecular Immunology2020，17，3： | 11 |
| 2 | Iodine biofortification of vegetable plants-An innovative method for iodine supplementation显示文摘To elevate the iodine level in edible plants has been shown to be an excellent approach to correct iodine deficiency.We have proposed an innovative approach to produce iodine supplementation by growing vegetables on soils with algal-based iodized organic fertilizer.Ten species of vegetables were tested.The biological absorption and migration of the iodine within the vegetable plants were revealed using microscopy with silver iodide precipitation technique.The results show that the absorption of iodine by the vegetable increases with increasing amount of the algal-based iodized organic fertilizer in general.And the uptake of iodine by leaf vegetable is significantly greater than that by fruit vegetable.Distribution of iodine in various plant organs shows a trend of decreasing iodine concentration from root,leaf,stalk,to fruit.A similar of decreasing concentration can also be found in various cells(cytoplasm>cytoderm>organelles).The exploration of the iodine uptake and biogeochemistry migration mechanisms provides an important scientific foundation for establishing a new method of producing a natural iodine supplementation by iodine biofortification of vegetables. | WENG HuanXin HONG ChunLai XIA TianHong BAO LiTing LIU HuiPing LI DeWang | 2013 | Chinese Science Bulletin2013，58，18： | 3 |
| 3 | Facile synthesis of CoFe_2O_4 nanoparticles anchored on graphene sheets for enhanced performance of lithium ion battery显示文摘Recently, metal oxides as high capacity anode materials had been investigated for lithium ion batteries.However, the fast capacity fading upon cycling leaded poor durability, which hindered their application as higher energy density of lithium ion battery. In this paper, a nanostructured nanocomposite with graphene supported CoFe_2O_4 nanoparticles(NPs) was prepared via simple hydrothermal reaction. The uniform CoFe_2O_4 NPs were anchored on graphene sheets, which brought a good performance on cyclability. Combined with the optimization of graphene content, the anode delivered a better capacity retention of 944 m A h g^(-1)over 50 cycles at current density of 100 m A g^(-1)and the good reversible capacity as 990 m A h g^(-1)when the rate returned from 5 A g^(-1)to 0.1 A g^(-1)after 60 cycles. The present work provided a desired structure for conversion anode materials or other electrode materials of large volume change. | Wen Qi Pei Li Ying Wu Hong Zeng Liting Hou Chunjiang Kuang Pei Yao Shaoxiong Zhou | 2016 | Progress in Natural Science:Materials International2016，26，5： | 1 |
| 4 | Effect of Roucongrong(Herba Cistanches Deserticolae) decoction on the substantia nigra through Wnt/β-catenin signaling pathway in rats with Parkinson's disease induced by 6-hydroxydopamine hydrochloride显示文摘OBJECTIVE:To investigate the effect of Roucongrong(Herba Cistanches Deserticolae)decoction on the substantia nigra in rats with Parkinson’s disease(PD)induced by 6-hydroxydopamine hydrochloride(6-OHDA).To further determine whether the Wnt/β-catenin signaling pathway is involved in the action.METHODS:A rat model of PD was established by intracranial injection of 6-OHDA.Subsequently,three concentrations of Roucongrong(Herba Cistanches Deserticolae)decoction were prepared and administered to rats by gavage therapy for 14 d.Behavioral changes were measured in PD rats.In vivo tyrosine hydroxylase(TH)levels in the substantia nigra were examined by immunohistochemistry.Additionally,gene and protein expression levels of members of the Wnt/β-catenin signaling pathway were examined by Western blotting and polymerase chain reaction.Lastly,a Wnt/β-catenin inhibitor was used to investigate the mechanism of action in 1-methyl-4-phenylpyridinium(MPP+)-treated MES23.5 cells in vitro.RESULTS:Roucongrong(Herba Cistanches Deserticolae)decoction improved performance in the stride and gait adjustment tests in PD rats.It also increased TH in the substantia nigra and altered the expression of genes and proteins in the Wnt/β-catenin signaling pathway.Wnt/β-catenin inhibitor reduced the effect of Roucongrong(Herba Cistanches Deserticolae)decoction in MPP+-treated MES23.5 cells.CONCLUSION:Roucongrong(Herba Cistanches Deserticolae)decoction may promote neuronal survival in PD in vivo and in vitro by increasing TH content in the substantia nigra and by activating the Wnt/β-catenin signaling pathway. | XU Qian QIN Wei WU Fangzhen LIN Yao HONG Liting CHEN Dan HU Xuefeng CAI Jing | 2021 | Journal of Traditional Chinese Medicine2021，41，5： | 1 |

| 6 | Molecular Basis of Unique Branching Phenotypes in Salvia splendens and the Role of PSY显示文摘The branching system of higher plants plays a very important role in plant morphogenesis,and the number of branches can directly affect crop yield and the ornamental value of plants.It is a complicated development process involving complex molecular mechanisms.The‘Cailinghong’variety of Salvia splendens is characterized by its great branching ability with the ability to grow into a spherical form naturally,without pinching.To gain insight into the molecular events during the branching development of S.splendens,suppressive subtractive hybridization(SSH)technology was used to screen differentially expressed genes between the erect plant type(strain 35)and the spherical plant type(‘Cailinghong’).In total,96 and 116 unigenes were annotated.Four and eight unigenes up-regulated in‘Cailinghong’and strain 35,respectively,were associated with plant hormone anabolism and signal transduction,suggesting that they participate in the branching process.One of these genes,phytoene synthase(PSY),is a precursor of the new plant hormone group strigolactones.Using the PSY fragment(192 bp)as a template,the cDNA sequence of PSY in S.splendens was cloned and named SsPSY.A relative expression analysis and transgenic test results indicated that SsPSY plays an important role in lateral branch development in‘Cailinghong’.These results provide new insight into the molecular mechanisms underlying branching in S.splendens. | Peipei Hong Mei Wang Liting Zhi Hongwei Chen Kefeng Liu Hongli Wang | 2022 | Phyton-International Journal of Experimental Botany2022，91，6： | 0 |
