Monosodium urate crystals trigger Nrf2- and heme oxygenase-1-dependent inflammation in THP-1 cells

Cellular & Molecular Immunology 2015年第4期12卷 424-434页

作者： Jhih-Jia Jhang yu-ting cheng cheng-Ying Ho Gow-Chin Yen Department of Food Science and Biotechnology National Chung Hsing University Taichung Taiwan China and ZAgricultural Biotechnology CenterNational Chung Hsing University Taichung Taiwan China Correspondence: Professor GC Yen Department of Food Science and Biotechnology National Chung Hsing University 250 Kuokuang Road Taichung40227 Taiwan China.

Gouty arthritis is an inflammatory disease that is caused by an accumulation of monosodium urate （MSU） crystals in the joints. MSU is capable of activating the nucleotide-binding oligomerization domain-like receptor pyrin domain containing 3 （NLRP3） inflammasome, leading to interleukin-lβ （IL-lβ） secretion. Reactive oxygen species （ROS） are major mediators of the NLRP3/IL-lβ interaction. Although nuclear factor E2-related factor 2 （Nrf2） is recognized as a transcription factor that is involved in the response to oxidative stress, the effect of MSU on Nrf2 and on Nrf2-mediated antioxidant enzymes remains unclear. The treatment of THP-1 monocytes using phorbol 12-myristate 13-acetate （PMA） was shown to initiate inflammatory responses. Here, we showed that THP-1 cells, following treatment with MSU crystals, significantly increased IL-1β release, NLRP3 inflammasome activation and ROS production. MSU also promoted the nuclear translocation of Nrf2 and activated lysosomal destabilization. Moreover, the levels of heme oxygenase-1 （HO-1） in gene and protein expressions were upregulated by MSU. MSU-induced IL-lβ secretion and NLRP3 inflammasome activation were inhibited by the knockdown of Nrf2 and via the HO-1 inhibitor zinc （11） protoporphyrin IX （ZnPP）. In addition, HO-1 inhibition increased the level of superoxide anion production and the consumption of glutathione. These findings suggest that Nrf2 and HO-1 mediate redox homeostasis and interact with pro-inflammatory factors in MSU-challenged THP-1 cells, thereby providing new insight into how MSU-induced gouty inflammation is mediated by specific mechanisms that are involved in the Nrf2/Ho-1 antioxidant signaling pathway.

作者： ZHONG yu-ting cheng Zi-Qiang MA Liang WANG Jia-Hong HAO Zhong-Hua WANG Qu-Quan Key Laboratory of Artificial Micro- and Nano-structures of the Ministry of Education and School of Physics and Technology Wuhan University Wuhan 430072

The nanostructured Au/AgxO/Ag sandwich multilayer films on quartz substrates are prepared by the magnetron sputtering method. The morphology, plasmon resonance and surface enhanced Raman scattering （SERS） activi- ties of the multilayer films are studied. The resonant absorption wavelength of localized surface plasmon is tuned in a wide range from 618nm to 993nm by controlling the density of nanoparticles of Au and Ag. The SERS activity of the Au/AgxO/Ag multilayer films are enhanced over -10 times compared with those of bare Ag and bare Au films. These properties may find a potential application in biosensor and bioimaging.

Actively tunable electromagnetically induced transparency in hybrid Dirac-VO2 metamaterials

引用

Optoelectronics Letters 2025年第1期21卷 13-20页

作者： DI Ke XIE Meng XIA Huarong cheng Anyu LIU yu DU Jiajia Department of Optoelectronic Engineering Chongqing University of Post and Telecommunications Chongqing Key Laboratory of Autonomous Navigation and Microsystem Chongqing University of Posts and Telecommunications Department of Automation Chongqing University of Post and Telecommunications

In this paper, we present a metamaterial structure of Dirac and vanadium dioxide（VO2） and investigate its optical properties using the finite-difference time-domain（FDTD） technique. Using the phase transition feature of VO2, the design can realize active tuning of the plasmon induced transparency（PIT） effect at terahertz frequency, thereby converting from a single PIT to a double-PIT. When VO2is in the insulating state, the structure is symmetric to obtain a single-band PIT effect. When VO2is in the metallic state, the structure turns asymmetric to realize a dual-band PIT effect. This design provides a reference direction for the design of actively tunable metamaterials. Additionally, it is discovered that the transparent window's resonant frequency and the Fermi level in this structure have a somewhat linear relationship. In addition, the structure achieves superior refractive index sensitivity in the terahertz band, surpassing 1 THz/RIU. Consequently, the design exhibits encouraging potential for application in refractive index sensors and optical switches.
