2Type 1 CD8^+ T Cells are Superior to Type 2 CD8^+ T Cells in Tumor Immunotherapy due to Their Efficient Cytotoxicity,Prolonged Survival and Type 1 Immune Modulation显示文摘CD8+ cytotoxic T(Tc) cells play a crucial role in host immune responses to cancer,and in this context,adoptive CD8+ Tc cell therapy has been studied in numerous animal tumor models. Its antitumor efficacy is,to a large extent,determined by the ability of Tc cells to survive and infiltrate tumors. In clinical trials,such in vitro-activated T cells often die within hours to days,and this greatly limits their therapeutic efficacy. CD8+ Tc cells fall into two subpopulations based upon their differential cytokine secretion. In this study,we in vitro generated that ovalbumin(OVA) -pulsed dendritic cell(DCOVA) -activated CD8+ type 1 Tc(Tc1) cells secreting IFN-γ,and CD8+ type 2 Tc(Tc2) cells secreting IL-4,IL-5 and IL-10,which were derived from OVA-specific T cell receptor(TCR) transgenic OT I mice. We then systemically investigated the in vitro and in vivo effector function and survival of Tc1 and Tc2 cells,and then assessed their survival kinetics after adoptively transferred into C57BL/6 mice,respectively. We demonstrated that,when compared to CD8+ Tc2,Tc1 cells were significantly more effective in perforin-mediated cytotoxicity to tumor cells,had a significantly higher capacity for in vivo survival after the adoptive T cell transfer,and had a significantly stronger therapeutic effect on eradication of well-established tumors expressing OVA in animal models. In addition,CD8+ Tc1 and Tc2 cells skewed the phenotype of CD4+ T cells toward Th1 and Th2 type,respectively. Therefore,the information regarding the differential effector function,survival and immune modulation of CD8+ Tc1 and Tc2 cells may provide useful information when preparing in vitro DC-activated CD8+ T cells for adoptive T cell therapy of cancer.Zhenmin Ye Chaoke Tang Shulin Xu Bei Zhang Xueshu Zhang Terence Moyana Jicheng Yang Jim Xiang 2007Cellular & Molecular Immunology2007,4,4:8

8Sortilin promotes macrophage cholesterol accumulation and aortic atherosclerosis through lysosomal degradation of ATP-binding cassette transporter A1 protein显示文摘Sortilin is closely associated with hyperlipidemia and the risk of atherosclerosis(AS).The role of sortilin and the underlying mechanism in peripheral macrophage are not fully understood.In this study,we investigated the effect of macrophage sortilin on ATP-binding cassette transporter A1(ABCA1)expression,ABCA1-mediated cholesterol efflux,and aortic AS.Macrophage sortilin expression was upregulated by oxidized low-density lipoproteins(ox-LDLs)in both concentration-and time-dependent manners.Its expression reached the peak level when cells were incubated with 50μg/ml ox-LDL for 24 h.Overexpression of sortilin in macrophage reduced cholesterol efflux,leading to an increase in intracellular total cholesterol,free cholesterol,and cholesterol ester.Sortilin was found to bind with ABCA1 protein and suppress macrophage ABCA1 expression,resulting in a decrease in cholesterol efflux from macrophages.The inhibitory effect of sortilin in cholesterol efflux was partially reversed by treatment with chloroquine,a lysosomal inhibitor.On the contrary,the ABCA1 protein level and ABCA1-mediated cholesterol efflux is increased by sortilin short hairpin RNA transfection.The fecal and biliary cholesterol 3H-sterol from cholesterol-laden mouse peritoneal macrophage was reduced by sortilin overexpression through lentivirus vector(LV)-sortilin in low-density lipoprotein receptor knockout mice,which was prevented by co-treatment with chloroquine.Treatment with LV-sortilin reduced plasma high-density lipoprotein and increased plasma ox-LDL levels.Accordingly,aortic lipid deposition and plaque area were exacerbated,and ABCA1 expression was reduced in mice in response to infection with LV-sortilin alone.These effects of LV-sortilin were partially reversed by chloroquine.Sortilin enhances lysosomal degradation of ABCA1 protein and suppresses ABCA1-mediated cholesterol efflux from macrophages,leading to foam cell formation and AS development.Yuncheng Lv Jing Yang Anbo Gao Sha Sun Xilong Zheng Xi Chen Wei Wan Chaoke Tang Wei Xie Suyun Li Dongming Guo Tianhong Peng Guojun Zhao Liyuan Zhong 2019Acta Biochimica et Biophysica Sinica2019,51,5:4

10Interleukin-5 promotes ATP-binding cassette transporter A1 expression through miR-211/JAK2/STAT3 pathways in THP-1-dervied macrophages显示文摘Interleukin-5 (IL-5) is manifested as its involvement in the process of atherosclerosis, but the mechanism is still unknown. In this study, we explored the effect of IL-5 on lipid metabolism and its underlying mechanisms in THP-1-derived macrophages. The quantitative polymerase chain reaction (qPCR) and western blot analysis results showed that IL-5 significantly up-regulated ATP-binding cassette transporter A1 (ABCA1) expression in a dose-dependent and time-dependent manner. [3H]-labeled cholesterol was used to assess the levels of cholesterol efflux, and the results showed that IL-5 increased ABCA1-mediated cholesterol efflux. A high-performance liquid chromatography assay indicated that cellular cholesterol content was decreased by IL-5 treatment in THP-1-derived macrophages. The selective inhibitor and small interfering RNA were used to block the Janus kinase (JAK)/signal transducer and activator of transcription 3 (STAT3) pathway. The results of the qPCR and western blot analysis showed that IL-5 activated JAK2/STAT3 pathway to up-regulate ABCA1 expression. Meanwhile, IL-5 reduced the expression level of miR-211. Furthermore, we found that JAK2 is a target gene of miR-211 and miR-211 mimic inhibited the expression of JAK2 and reduced the levels of p-STAT3 and ABCA1 as revealed by luciferase reporter assay, qPCR and western blot analysis. In summary, these findings indicated that IL-5 promotes ABCA1 expression and cholesterol efflux through the miR-211/JAK2/STAT3 signaling pathway in THP-1-derived macrophages.Kong Chen Zhenwang Zhao Gang Wang Jin Zou Xiaohua Yu Dawei Zhang Gaofeng Zeng Chaoke Tang 2020Acta Biochimica et Biophysica Sinica2020,52,8:3
11Interferon γ Stimulates Cellular Maturation of Dendritic Cell Line DC2.4 Leading to Induction of Efficient Cytotoxic T Cell Responses and Antitumor Immunity显示文摘Dendritic cells (DCs) are the most potent antigen-presenting cells (APCs) for the initiation of antigen (Ag)-specific immune responses. In most studies, mature DCs are generated from bone marrow cells or peripheral monocytes; in either case, the harvested cells are then cultured in medium containing recombinant GM-CSF, IL-4 and TNF-α for 7-10 days and stimulated with lipopolysaccharide (LPS). However, this approach is time-consuming and expensive. There is another less cost approach of using immobilized DC cell lines, which can easily grow in the medium. A disadvantage with the immobilized DC cell lines, however, is that they are immature DCs and lack expression of MHC class II and costimulatory CD40 and CD80 molecules. This, therefore, limits their capacity for inducing efficient antitumor immunity. In the current study, we investigated the possible efficacy of various stimuli (IL-1β, IFN-γ, TNF-α, CpG and LPS) in converting the immature dendritic cell line DC2.4 to mature DCs. Our findings were quite interesting since we demonstrated for the first time that IFN-γ was able to stimulate the maturation of DC2.4 cells. The IFN-γ-activated ovalbumin (OVA)-pulsed DC2.4 cells have capacity to upregulate MHC class II, CD40, CD80 and CCR7, and to more efficiently stimulate in vitro and in vivo OVA-specific CD8+ T cell responses and antitumor immunity. Therefore, IFN-γ-activated immortal DC2.4 cells may prove to be useful in the study of DC biology and antitumor immunity.Tianpei He Chaoke Tang Shulin Xu Terence Moyana Jim Xiang 2007Cellular & Molecular Immunology2007,4,2:3

13Preparation and application of iron oxide/persimmon tannin/graphene oxide nanocomposites for efficient adsorption of erbium from aqueous solution显示文摘Rare earth elements(REEs)are used for the developme nt of new energy materials owing to their intrinsic physicochemical property.However,excess REEs in water threaten the safety of animals,plants and humans.An efficient way to separate REEs from the water is therefore needed.In this study,a biosorbent consisting of iron oxide(Fe3 O4),persimmon tannin(PT),and graphene oxide(GO)as Fe3 O4/PT/GO was prepared,and the adsorption of trivalent erbium(Er3+)ions from aqueous solution was investigated.The adsorption process for Er3+ions conforms to pseudo-second order kinetic and the Langmuir isotherm model behavior.Thermodynamic studies indicate that the adsorption process is spontaneous and endothermic.Scanning electron microscopy(SEM),X-ray photoelectron spectroscopy(XPS),X-ray diffraction(XRD),thermogravimetric analysis(TGA).Fourier-transform infrared(FT-IR)spectroscopy;Brunauer-Emmett-Teller(BET)analysis,and vibrating sample magnetometer(VSM)were used to assess the adsorption mechanism of Er3+ions onto the Fe3 O4/PT/GO biosorbent.A combination of electrostatic interactions,redox reactivity and chelation are responsible for adsorption of Er3+ions on the Fe3 O4/PT/GO biosorbent,The magnetic Fe3 O4/PT/GO biosorbent can be easily separated under the magnetic field for effective recycle of Er3+ions from aqueous solution.Therefore,this new biomass composite holds great promise for wastewater treatment.Lin Gao Zhongmin Wang Chaoke Qin Zhenming Chen Mingmin Gao Na He Xi Qian Zhide Zhou Guiyin Li 2020Journal of Rare Earths2020,38,12:3
14The antiatherogenic function of kallistatin and its potential mechanism显示文摘Atherosclerosis is the pathological basis of most cardiovascular diseases,the leading cause of morbidity and mortality worldwide.Kallistatin,originally discovered in human serum,is a tissuekallikrein-binding protein and a unique serine proteinase inhibitor.Upon binding to its receptor integrin p3,lipoprotein receptor-related protein 6,nucleolin,or Krüppel-like factor 4,kallistatin can modulate various signaling pathways and affect multiple biological processes,including angioge esis,inflammatory response,oxidative stress,and tumor growth.Circulating kallistatin levels are sign ificantly decreased in patie nts with coronary artery disease and show an in verse correlati on with its severity.Importantly,both in vitro and in vivo experime nts have dem on strated that kallistatin reduces atherosclerosis by inhibiting vascular in flammation,antagonizing endothelial dysfunction,and improving lipid metabolism.Thus,kallistatin may be a novel biomarker and a promising therapeutic target for atherosclerosis-related diseases.In this review,we focus on the antiatherogenic function of kallistatin and its potential mechanism.Gang Wang Jin Zou Xiaohua Yu Shanhui Yin Chaoke Tang 2020Acta Biochimica et Biophysica Sinica2020,52,6:2

16Myristica fragrans promotes ABCA1 expression and cholesterol efflux in THP-1-derived macrophages显示文摘Myristica fragrans is a traditional herbal medicine and has been shown to alleviate the development of atherosclerosis.However,the anti-atherogenic mechanisms of M.fragrans are still to be addressed.In this study,we explored the effect of M.fragrans on lipid metabolism and inflammation and its mechanisms in THP-1-derived macrophages.The quantitative polymerase chain reaction and western blot analysis results showed that M.fragrans promotes cholesterol efflux from THP-1-derived macrophages and reduces intracellular total cholesterol,cholesterol ester,and free cholesterol contents in a dose-and a time-dependent manner.Further study found that liver X receptor alpha(LXRα)antagonist GGPP significantly blocked the upregulation of ABCA1 expression with M.fragrans treatment.In addition,chromatin immunoprecipitation assay confirmed that GATA binding protein 3(GATA3)can bind to the LXRαpromoter,and inhibition of GATA3 led to the downregulation of LXRαand ATP-binding cassette subfamily A member 1 expression.Furthermore,M.fragrans reduced lipid accumulation,followed by decreasing tumor necrosis factor-α,interleukin(IL)-6,and IL-1βand increasing IL-10 produced by THP-1-derived macrophages.Therefore,M.fragrans is identified as a valuable therapeutic medicine for atherosclerotic cardiovascular disease.Shangming Liu Jiahui Gao Linhao He Zhenwang Zhao Gang Wang Jin Zou Li Zhou Xiangjun Wan Shilin Tang Chaoke Tang 2021Acta Biochimica et Biophysica Sinica2021,53,1:2
