1In situ preparation of g-C3N4/Bi4O5I2 complex and its elevated photoactivity in Methyl Orange degradation under visible light显示文摘A graphite carbon nitride(g-C3N4)modified Bi4O5I2 composite was successfully prepared insitu via the thermal treatment of a g-C3N4/Bi OI precursor at 400°C for 3 hr.The as-prepared g-C3N4/Bi4O5I2 showed high photocatalytic performance in Methyl Orange(MO)degradation under visible light.The best sample presented a degradation rate of 0.164 min^-1,which is 3.2 and 82 times as high as that of Bi4O5I2 and g-C3N4,respectively.The g-C3N4/Bi4O5I2 was characterized by X-ray powder diffractometer(XRD),scanning electron microscopy(SEM),transmission electron microscopy(TEM),Raman,X-ray photoelectron spectroscopy(XPS),ultraviolet-visible diffuse reflectance spectra(DRS),electrochemical impedance spectroscopy(EIS)and transient photocurrent response in order to explain the enhanced photoactivity.Results indicated that the decoration with a small amount of g-C3N4 influenced the specific surface area only slightly.Nevertheless,the capability for absorbing visible light was improved measurably,which was beneficial to the MO degradation.On top of that,a strong interaction between g-C3N4 and Bi4O5I2 was detected.This interplay promoted the formation of a favorable heterojunction structure and thereby enhanced the charge separation.Thus,the g-C3N4/Bi4O5I2 composite presented greater charge separation efficiency and much better photocatalytic performance than Bi4O5I2.Additionally,g-C3N4/Bi4O5I2 also presented high stability.·O2^- and holes were verified to be the main reactive species.Zhe Feng Lin Zeng Qingle Zhang Shifeng Ge Xinyue Zhao Hongjun Lin Yiming He 2020Journal of Environmental Sciences2020,32,1:12
2Allogeneic Vγ9Vδ2 T-cell immunotherapy exhibits promising clinical safety and prolongs the survival of patients with late-stage lung or liver cancer显示文摘Vγ9Vδ2 T cells are promising candidates for cellular tumor immunotherapy.Due to their HLA-independent mode of action,allogeneic Vγ9Vδ2 T cells can be considered for clinical application.To apply allogeneic Vγ9Vδ2 T cells in adoptive immunotherapy,the methodology used to obtain adequate cell numbers with optimal effector function in vitro needs to be optimized,and clinical safety and efficacy also need to be proven.Therefore,we developed a novel formula to improve the expansion of peripheralγδT cells from healthy donors.Then,we used a humanized mouse model to validate the therapeutic efficacy of expandedγδT cells in vivo;furthermore,the expandedγδT cells were adoptively transferred into late-stage liver and lung cancer patients.We found that the expanded cells possessed significantly improved immune effector functions,including proliferation,differentiation,and cancer cell killing,both in vitro and in the humanized mouse model.Furthermore,a phase I clinical trial in 132 late-stage cancer patients with a total of 414 cell infusions unequivocally validated the clinical safety of allogeneic Vγ9Vδ2 T cells.Among these 132 patients,8 liver cancer patients and 10 lung cancer patients who received≥5 cell infusions showed greatly prolonged survival,which preliminarily verified the efficacy of allogeneic Vγ9Vδ2 T-cell therapy.Our clinical studies underscore the safety and efficacy of allogeneic Vγ9Vδ2 T-cell immunotherapy,which will inspire further clinical investigations and eventually benefit cancer patients.Yan Xu Zheng Xiang Mohammed Alnaggar Léonce Kouakanou Jiawei Li Junyi He Jiashuang Yang Yi Hu Yan Chen Li Lin Jianlei Hao Jingxia Li Jibing Chen Man Li Qingling Wu Christian Peters Qinghua Zhou Jianshuang Li Yingqing Liang Xiaohua Wang Baohui Han Meili Ma Dieter Kabelitz Kecheng Xu Wenwei Tu Yangzhe Wu Zhinan Yin 2021Cellular & Molecular Immunology2021,18,2:8
3Calcium carbonate nanoparticles promote osteogenesis compared to adipogenesis in human bone-marrow mesenchymal stem cells显示文摘Rhombohedron-like and fusiform calcium carbonate nanoparticles were fabricated using a new method. Their geometry was controlled by varying the mixing speed and ratio of ethanol versus water in reaction system. The calcium carbonate nanoparticles(CCNPs) have slight effect on viability of human bone-marrow mesenchymal stem cells(hBMSCs) with dose-dependent and shape-dependent, but they can significantly promote osteogenic differentiation of hBMSCs in vitro by 10–37% increase of alkaline phosphatase(ALP) activity, 9–36% growth of collagen secretion and 1.13–1.83 folds upregulation of osteogenesis-related genes, even at lower dose ranges(5–20 μg/ml). The efficacity of promoting osteogenesis depends on the shape and dose of CCNPs. Furthermore,adipogenesis was inhibited by less accumulation of lipid droplets, lower triglyceride(TG) secretion and downregulation of adipogenesis-related genes. These findings improve the understanding of effects CCNPs on hBMSCs fate towards osteoblasts or adipocytes and have meaningful impact for combining use of CCNPs and hBMSCs in tissue engineering and regenerative medicine fields.Xiaoning Li Xing Yang Xujie Liu Wei He Qianli Huang Shengrong Li Qingling Feng 2018Progress in Natural Science:Materials International2018,28,5:3
4Nanoparticles and their effects on differentiation of mesenchymal stem cells显示文摘Over the past decades,advancements in nanoscience and nanotechnology have resulted in numerous nanomedicine platforms.Various nanoparticles,which exhibit many unique properties,play increasingly important roles in the field of biomedicine to realize the potential of nanomedicine.Due to the capacity of self-renewal and multilineage mesenchymal differentiation,mesenchymal stem cells(MSCs)have been widely used in the area of regenerative medicine and in clinical applications due to their potential to differentiate into various lineages.There are several factors that impact the differentiation of MSCs into different lineages.Many types of biomaterials such as polymers,ceramics,and metals are commonly applied in tissue engineering and regenerative therapies,and they are continuously refined over time.In recent years,along with the rapid development of nanotechnology and nanomedicine,nanoparticles have been playing more and more important roles in the fields of biomedicine and bioengineering.The combined use of nanoparticles and MSCs in biomedicine requires greater knowledge of the effects of nanoparticles on MSCs.This review focuses on the effects of four inorganic or metallic nanoparticles(hydroxyapatite,silica,silver,and calcium carbonate),which are widely used as biomaterials,on the osteogenic and adipogenic differentiation of MSCs.In this review,the cytotoxicity of these four nanoparticles,their effects on osteogenic/adipogenic differentiation of MSCs and the signalling pathways or transcription factors involved are summarized.In addition,the chemical composition,size,shape,surface area,surface charge and surface chemistry of nanoparticles,have been reported to impact cellular behaviours.In this review,we particularly emphasize the influence of their size on cellular responses.We envision our review will provide a theoretical basis for the combined application of MSCs and nanoparticles in biomedicine.Xing Yang Yuanyuan Li Xujie Liu Wei He Qianli Huang Qingling Feng 2020Biomaterials Translational2020,1,1:1

12Tetratricopeptide repeat domain 36 deficiency mitigates renal tubular injury by inhibiting TGF-β1-induced epithelialemesenchymal transition in a mouse model of chronic kidney disease显示文摘The damage of proximal tubular epithelial cells(PTECs)is considered a central event in the pathogenesis of chronic kidney disease(CKD)and deregulated repair processes of PTECs result in epithelialemesenchymal transition(EMT),which in turn aggravates tubular injury and kidney fibrosis.In this study,we firstly revealed that the reduction of TTC36 is associated with unilateral ureteral obstruction(UUO)-induced CKD;besides,ablation of TTC36 attenuated tubular injury and subsequent EMT in UUO-treated mice kidneys.Consistently,TTC36 overexpression promoted EMT in TGF-β1-induced HK2 cells.Moreover,TTC36 elevated the protein expression of CEBPB,which was involved in the regulation of TGF-β/SMAD3 signaling,and augmented SMAD3 signaling and downstream genetic response were reduced by CEBPB silencing.Collectively,our results uncovered that TTC36 deficiency plays a protective role in tubular injury and renal fibrosis triggered by UUO;further,TTC36 overexpression exacerbated TGF-β/SMAD3 signaling via elevating the stability of SMAD3 and CEBPB,suggesting that TTC36 inhibition may be a potential strategy in the therapy of obstructive nephropathy.Xin Yan Rui Peng Yilu Ni Lei Chen Qingling He Qianyin Li Qin Zhou 2022Genes & Diseases2022,9,6:0
