| 1 | Hangzhou criteria as downstaging criteria in hepatocellular ca显示文摘Background:The downstaging of hepatocellular carcinoma(HCC)has been confirmed to benefit liver transplantation(LT)patients whose tumors are beyond the transplantation criteria.Milan criteria(MC),a tumor size and number-based assessment,is currently used as the endpoint in these patients.However,many studies believe that tumor biological behavior should be added to the evaluation criteria for downstaging efficacy.Hence,this study aimed to explore the feasibility of Hangzhou criteria(HC),which introduced tumor grading and alpha-fetoprotein in addition to tumor size and number,as an endpoint of downstaging.Methods:We performed a multicenter and retrospective study of 206 patients accepted locoregional therapy(LRT)as downstaging/bridge treatment prior to LT in three centers of China.Results:Recipients were divided into four groups:failed downstaging to the HC(group A,n=46),successful downstaging to the HC(group B,n=30),remained within the HC all the time(group C,n=113),and tumor progressed(group D,n=17).The 3-year HCC recurrence probabilities of groups B and C were not significantly different(10.3%vs.11.6%,P=0.87).The HCC recurrent rate was significantly higher in group A(52.3%)compared with that in group B/C(P<0.05).Seven patients(7/76,9.2%)whose tumor exceeded the the HC were successfully downstaged to the MC,and 39.5%(30/76)to the the HC.In group B,23 patients remained beyond the MC and their survivals were as well as those of patients within the MC.Conclusions:Compared to the MC,HC downstaging criteria can give more HCC patients access to LT and furthermore,the outcome of these patients is the same as those matching MC downstaging criteria.Hangzhou downstaging criteria therefore is applicable in clinical practice. | Qi-Fan Zhan Sun-Bin Ling Yi-Nan Deng Qiao-Nan Shan Qian-Wei Ye Sheng-Jun Xu Guang-Jiang Jiang Di Lu Xu-Yong Wei Li Zhuang Wu Zhang Tian Shen Bei-Ni Cen Hai-Yang Xie Ji-Min Liu Jian Wu Shu-Sen Zheng Yang Yang Xiao Xu | 2020 | Hepatobiliary & Pancreatic Diseases International2020，19，4： | 11 |
| 2 | Targeting HMGB1 for the treatment of sepsis and sepsis-induced organ injury显示文摘High mobility group box 1(HMGB1)is a ubiquitous nuclear protein that is present in almost all cells and regulates the activity of innate immune responses in both intracellular and extracellular settings.Current evidence suggests that HMGB1 plays a pivotal role in human pathological and pathophysiological processes such as the inflammatory response,immune reactions,cell migration,aging,and cell death.Sepsis is a systemic inflammatory response syndrome(SIRS)that occurs in hosts in response to microbial infections with a proven or suspected infectious etiology and is the leading cause of death in intensive care units worldwide,particularly in the aging population.Dysregulated systemic inflammation is a classic characteristic of sepsis,and suppression of HMGB1 may ameliorate inflammation and improve patient outcomes.Here,we focus on the latest breakthroughs regarding the roles of HMGB1 in sepsis and sepsis-related organ injury,the ways by which HMGB1 are released,and the signaling pathways and therapeutics associated with HMGB1.This review highlights recent advances related to HMGB1:the regulation of HMBG1 might be helpful for both basic research and drug development for the treatment of sepsis and sepsis-related organ injury. | Chao Deng Lin Zhao Zhi Yang Jia-jia Shang Chang-yu Wang Ming-zhi Shen Shuai Jiang Tian Li Wen-cheng Di Ying Chen He Li Ye-dong Cheng Yang Yang | 2022 | Acta Pharmacologica Sinica2022，43，3： | 11 |
| 3 | In-situ fabrication of PtSe2/GaN heterojunction for self-powered deep ultraviolet photodetector with ultrahigh current on/off ratio and detectivity显示文摘The research of ultraviolet photodetectors(UV PDs)have been attracting extensive attention,due to their important applications in many areas.In this study,PtSe2/GaN heterojunction is in-situ fabricated by synthesis of large-area vertically standing two-dimensional(2D)PtSe2 film on n-GaN substrate.The PtSe2/GaN heterojunction device demonstrates excellent photoresponse properties under illumination by deep UV light of 265 nm at zero bias voltage.Further analysis reveals that a high responsivity of 193 mA·W^-1,an ultrahigh specific detectivity of 3.8 × 10^14 Jones,linear dynamic range of 155d B and current on/off ratio of^10^8,as well as fast response speeds of 45/102μs were obtained at zero bias voltage.Moreover,this device response quickly to the pulse laser of 266 nm with a rise time of 172 ns.Such high-performanee PtSe2/GaN heteroj u nction UV PD demonstrated in this work is far superior to previously reported results,suggesting that it has great potential for deep UV detection. | Ranran Zhuo Longhui Zeng Huiyu Yuan Di Wu Yuange Wang Zhifeng Shi Tingting Xu Yongtao Tian Xinjian Li Yuen Hong Tsang | 2019 | Nano Research2019，12，1： | 11 |
| 4 | Effects of multidrug resistance, antisense RNA on the chemosensitivity of hepatocellular carcinoma cells显示文摘BACKGROUND: Multidrug resistance is a major obstacle in cancer chemotherapy. We examined whether the antisense RNA of multidrug resistance gene 1 (mdr1) could reverse multidrug resistance in the human hepatocellular carcinoma (HCC) cell line SMMC7721/ADM. METHODS: The recombinant adenoviruses pAdEasy- GFP-ASmdr1 product was produced by the adenoviral vector AdEasy system, which can express antisense RNA against the mdr1 gene. Following that, the recombinant adenovirus was transfected into the P-glycoprotein- producing multidrug resistance cell line, SMMC7721/ADM human HCC cells resistant to adriamycin (ADM) and daunorubicin (DNR). In order to investigate the reversal of multidrug resistance phenotype, we measured the expression of mdr1 mRNA by RT-PCR and the production of P-glycoprotein by flow cytometry. The sensitivities for ADM and DNR SMMC7721/ADM cells were examined by [3-(4, 5-dimethylthi-azol-2-yl)-2,5 diphenyl-terazolium bromide] (MTT) analysis. RESULTS: The low-level expression of mdr1 mRNA and P-glycoprotein production were observed in parental sensitive cells SMMC/7721 in addition to the overexpressionof mdr1 mRNA and P-glycoprotein in SMMC7721/ADM cells. The transfection of antisense-RNA into SMMC7721/ ADM cells resulted in decreases of mdr1 mRNA and P-glycoprotein, but increase of drug sensitivities. The sensitivities of transfected SMMC7721/ADM cells to ADM and DNR in IC50 reduced by 31.25% and 62.96% respectively. CONCLUSIONS: Mdr1 antisense RNA can increase the sensitivities of SMMC7721/ADM cells to anticancer drug by decreasing the expression of the mdr1 gene and inhibiting P-glycoprotein expression. This strategy may be applicable to cancer patients with P-glycoportein mediated multidrug resistance. | Bo Li, Tian Ye, Lei Zhao, De-Hua Li, Xing-Hua Gou, Lan-Ying Zhao, Lei Han, Lin Chen, Lu-Nan Yan and Jian-Ping Gong Department of Hepatobiliary Surgery, Second Affiliated Hospital, Chongqing University of Medical Sciences, Chongqing 400010, China Department of Traditional Chinese Surgery, Second Affiliated Hospital, Luzhou Medical College, Luzhou 646000, China Genetic Engineering Laboratory, Chengdu Di’ao Group Co., Ltd., Chengdu 610041, China Department of General Surgery, West China Hospital, Sichuan University, Chengdu 610041, China | 2006 | Hepatobiliary & Pancreatic Diseases International2006，5，4： | 10 |
| 5 | Hot workability characteristics of Rene88DT superalloy with directionally solidified microstructure显示文摘The hot deformation characteristics of Rene88 DT superalloy with directionally solidified microstructure produced by electroslag remelting continuous directionally solidification(ESR-CDSò) were studied in the temperature range of 1,040–1,140 °C and strain rate range of 0.001–1.000 s-1by hot compression tests. Flow curves for Rene88 DT alloy with initial directionally solidified(DS)microstructure exhibit pronounced peak stresses at the early stage of deformation followed by the occurrence of dynamic softening phenomenon. Rene88 DT alloy with DS microstructure shows higher flow peak stresses compared with HIPed P/M superalloy FGH4096, but the disparities in peak stresses between ESR-CDSed Rene88 DT and HIPed P/M superalloy FGH4096 reduce as temperature increases. The improvement of hot workability of DS alloy with columnar grains avoiding the maximum shear stress comes true. A hot deformation constitutive equation as a function of strain that describes the dependence of flow stress on strain rate and temperature is established. Hot deformation apparent activation energy(Q) varies not only with the strain rate and temperature but also with strain. The strain rate sensitivity exponent(m) map is established at the strain of 0.8, which reveals that global dynamic recrystallization(DRX) shows a relatively high m value in a large strain compression.Optimum parameters are predicted in two regions:T = 1,100–1,130 °C,_e = 0.100–1.000 s-1and T = 1,080–1,100 °C,_e = 0.010–0.100 s-1, which is based on processing maps and deformation microstructure observations. | Fu-Lin Li Rui Fu Di Feng Zhi-Ling Tian | 2015 | Rare Metals2015，34，1： | 9 |

| 7 | Effect of a transverse plasma jet on a shock wave induced by a ramp显示文摘We conducted experiments in a wind tunnel with Mach number 2 to explore the evolution of a transverse plasma jet and its modification effect on a shock wave induced by a ramp with an angle of 24°. The transverse plasma jet was created by arc discharge in a small cylindrical cavity with a 2 mm diameter orifice. Three group tests with different actuator arrangements in the spanwise or streamwise direction upstream from the ramp were respectively studied to compare their disturbances to the shock wave. As shown by a time-resolved schlieren system, an unsteady motion of the shock wave by actuation was found: the shock wave was significantly modified by the plasma jet with an upstream motion and a reduced angle. Compared to spanwise actuation, a more intensive impact was obtained with two or three streamwise actuators working together. From shock wave structures, the control effect of the plasma jet on the shock motion based on a thermal effect, a potential cause of shock modification, was discussed. Furthermore, we performed a numerical simulation by using the Improved Delayed Detached Eddy Simulation(IDDES) method to simulate the evolution of the transverse plasma jet plume produced by two streamwise actuators. The results show that flow structures are similar to those identified in schlieren images. Two streamwise vortices were recognized, which indicates that the higher jet plume is the result of the overlap of two streamwise jets. | Hongyu WANG Jun LI Di JIN Hui DAI Tian GAN Yun WU | 2017 | Chinese Journal of Aeronautics2017，30，6： | 7 |
| 8 | Functional metabolomics reveal the role of AHR/GPR35 mediated kynurenic acid gradient sensing in chemotherapy-induced intestinal damage显示文摘Intestinal toxicity induced by chemotherapeutics has become an important reason for the interruption of therapy and withdrawal of approved agents. In this study, we demonstrated that chemotherapeutics-induced intestinal damage were commonly characterized by the sharp upregulation of tryptophan(Trp)àkynurenine(KYN)àkynurenic acid(KA) axis metabolism. Mechanistically,chemotherapy-induced intestinal damage triggered the formation of an interleukin-6(IL-6)àindoleamine2,3-dioxygenase 1(IDO1)àaryl hydrocarbon receptor(AHR) positive feedback loop, which accelerated kynurenine pathway metabolism in gut. Besides, AHR and G protein-coupled receptor 35(GPR35) negative feedback regulates intestinal damage and inflammation to maintain intestinal integrity and homeostasis through gradually sensing kynurenic acid level in gut and macrophage, respectively. Moreover, based on virtual screening and biological verification, vardenafil and linagliptin as GPR35 and AHR agonists respectively were discovered from 2388 approved drugs. Importantly, the results that vardenafil and linagliptin significantly alleviated chemotherapy-induced intestinal toxicity in vivo suggests that chemotherapeutics combined with the two could be a promising therapeutic strategy for cancer patients in clinic.This work highlights GPR35 and AHR as the guardian of kynurenine pathway metabolism and core component of defense responses against intestinal damage. | Di Wang Danting Li Yuxin Zhang Jie Chen Ying Zhang Chuyao Liao Siyuan Qin Yuan Tian Zunjian Zhang Fengguo Xu | 2021 | Acta Pharmaceutica Sinica B2021，11，3： | 4 |
| 9 | Anti-BCMA CAR T-cell therapy CT103A in relapsed or refractory AQP4-IgG seropositive neuromyelitis optica spectrum disorders:phase 1 trial interim results显示文摘Chimeric antigen receptor(CAR)T-cell therapy that targets B-cell maturation antigen(BCMA)have great potentials in autoimmune diseases and could be novel therapeutics for relapsed/refractory neuromyelitis optica spectrum disorder(NMOSD).To evaluate the safety and efficacy of the CT103A,a self-developed BCMA-targeting CAR construct against BCMA,in patients with AQP4-IgG seropositive NMOSD,an ongoing,investigator-initiated,open-label,single-arm,phase 1 clinical trial is conducted at our center.In total,12 patients were administered with a CAR-BCMA infusion.Ten of the 12 patients dosed were women(83.3%),with a median age of 49.5 years(range,30-67).were The most common events of grade 3 or higher were hematologic toxic effects.Seven patients(58%)developed infections,but no grade 4 infections occurred.Cytokine release syndrome was reported in all patients with only events of grade 1 or 2 observed.During the follow-up of a median 5.5 months,11 patients had no relapse;all patients generally reported improvement in disabilities and quality-of-life outcomes;11 patients’AQP-4 antibodies in serum showed a downward trend by the cutoff date.CAR T-cell expansion was associated with responses,and persisted more than 6 months post-infusion in 17%of the patients.In summary,CAR T-cell therapy shows a manageable safety profile and therapeutic potentials for patients with relapsed/refractory AQP4-IgG seropositive NMOSD.Another expansion phase is currently underway to determine the safety and efficacy of CAR T-BCMA infusion in patients with other neuro-inflammatory diseases. | Chuan Qin Dai-Shi Tian Luo-Qi Zhou Ke Shang Liang Huang Ming-Hao Dong Yun-Fan You Jun Xiao Ying Xiong Wen Wang Hao Pang Jing-Jing Guo Song-Bai Cai Di Wang Chun-Rui Li Min Zhang Bi-Tao Bu Wei Wang | 2023 | Signal Transduction and Targeted Therapy2023，8，2： | 4 |
| 10 | Highly sensitive solar-blind deep ultraviolet photodetector based on graphene/PtSe_(2)/β-Ga_(2)O_(3)2D/3D Schottky junction with ultrafast speed显示文摘There is an emerging need for high-sensitivity solar-blind deep ultraviolet(DUV)photodetectors with an ultra-fast response speed.Although nanoscale devices based on Ga_(2)O_(3)nanostructures have been developed,their practical applications are greatly limited by their slow response speed as well as low specific detectivity.Here,the successful fabrication of two-/three-dimensional(2D/3D)graphene(Gr)/PtSe2/β-Ga_(2)O_(3)Schottky junction devices for high-sensitivity solar-blind DUV photodetectors is demonstrated.Benefitting from the high-quality 2D/3D Schottky junction,the vertically stacked structure,and the superior-quality transparent graphene electrode for effective carrier collection,the photodetector is highly sensitive to DUV light illumination and achieves a high responsivity of 76.2 mA/W,a large on/off current ratio of~105,along with an ultra-high ultraviolet(UV)/visible rejection ratio of 1.8×104.More importantly,it has an ultra-fast response time of 12µs and a remarkable specific detectivity of~1013 Jones.Finally,an excellent DUV imaging capability has been identified based on the Gr/PtSe2/β-Ga_(2)O_(3)Schottky junction photodetector,demonstrating its great potential application in DUV imaging systems. | Di Wu Zhihui Zhao Wei Lu Lukas Rogée Longhui Zeng Pei Lin Zhifeng Shi Yongtao Tian Xinjian Li Yuen Hong Tsang | 2021 | Nano Research2021，14，6： | 4 |

| 12 | CRISPR/Cas9-mediated Tyrosine hydroxylase knockout resulting in larval lethality in Agrotis ipsilon显示文摘Tyrosine hydroxylase (TH)is involved in insect melanin and the catecholamine biosynthesis pathway.TH as an enzyme catalyzing the conversion of tyrosine to 3,4- dihydroxyphenylalanine is the first step reaction in the pathway.Although TH has been proven to affect the pigmentation of the epidermis and development in many insects,there is no report about physiological function of the THgene inAgrotis ipsilon.Here we cloned the TH gene from A.ipsilon.Semi-quantitative real-time polymerase chain reaction (PCR) analysis showed that AiTH was expressed at all development stages.Moreover,its high expression levels in the head and epidermis suggest that it is mainly related to pigment deposition and insect development.Then,we used the clustered regularly interspaced short palindromic repeats (CRISPR)/CRISPR-associated protein 9system to target the AiTH gene:deletion events were detected at the target sites.Compared with the control group,a few mutants with the phenomenon of narrowing in the egg shell and embryos can develop but cannot hatch;the other hatched embryos were seriously dehydrated after hatching and died within the first day.Quantitative real-time PCR analysis revealed that THwas down-regulated inAiTHmutants.Here,our work demonstrated thatAiTHplays an important role in growth and development of newly hatched larvae;meanwhile,it would be a promising target to explore a control strategy for A.ipsilon. | Yang Yang Yao-Hui Wang Xi-En Chen Di Tian Xia Xu Kai Li Yong-Ping Huang Lin He | 2018 | Insect Science2018，25，6： | 3 |
| 13 | A highly sensitive chemiluminescence sensor for detecting mercury(Ⅱ) ions: a combination of Exonuclease Ⅲ-aided signal amplification and graphene oxide-assisted background reduction显示文摘In this paper, we report a highly sensitive chemiluminescence(CL) sensor for Hg2+ ions based on thymine-Hg2+-thymine(T-Hg2+-T) coordination chemistry. We designed a thymine rich oligonucleotide as a capture probe and a signal probe that includes two functional domains: a horseradish peroxidase-mimicking DNAzyme domain for the generation of CL, and a recognition domain. Graphene oxide(GO) was introduced to adsorb the signal probe via π-π interaction, which brought the DNAzyme domain and GO into close proximity and quenches CL. In the presence of Hg2+ ions, the coordination of Hg2+ with the capture probe yielded a hairpin complex, triggers cascaded strand displacement reactions and Exonuclease III-assisted signal amplifications. As a result, accumulated amounts of DNAzyme were generated and released from GO, leading to an enhanced CL signal. This strategy combines enzyme-based signal amplification and GO as a background reducer, leads to a limit of detection(LOD) of 2 nmol/L. This simple detection system provides a label-free yet sensitive approach for detection of Hg2+ ions. | Yang Tian Yue Wang Yan Xu Yang Liu Di Li Chunhai Fan | 2015 | Science China Chemistry2015，58，3： | 3 |
| 14 | BMI and BMI Changes to All-cause Mortality among the Elderly in Beijing: a 20-year Cohort Study显示文摘Objective To explore the association between body mass index(BMI)and all-cause mortality among the elderly in Beijing.Methods This analysis was based on the Beijing multidimensional longitudinal study of aging(BLSA),which included 2,090 subjects over 55 years old and was followed-up from 1992 to 2012.BMI-mortality curves were drawn to find the optimal BMI range with the lowest mortality.Cox proportional hazard models were used to obtain the hazard ratios(HRs)for BMI and BMI changes in the overall population and in specific stratified populations.Results During follow-up,1,164 deaths were recorded;BMI-mortality curve was U-shaped,with the lowest mortality at a BMI of approximately 25 kg/m^2.After adjusting for gender,age,smoking,drinking and some pre-existing diseases,HRs for underweight,overweight and obesity compared with normal weight were 1.372(95%CI:1.154-1.631),0.767(95%CI:0.666-0.884)and 0.871(95%CI:0.830-1.246),respectively.HR for BMI drop was 3.245(95%CI:0.824-12.772)in the underweight group and 1.892(95%CI:0.830-1.246)in the normal weight group,HR for BMI rise was 1.795(95%CI:1.243-2.591)in normal weight group and 1.962(95%CI:1.202-3.203)in the overweight group.Conclusion Keeping BMI in an overweight status and stable is related to a reduced mortality. | WANG Yun Feng TANG Zhe GUO Jin TAO Li Xin LIU Long LI Hai Bin LI Di Tian GUO Xiu Hua YANG Xing Hua | 2017 | Biomedical and Environmental Sciences2017，30，2： | 3 |
| 15 | Application of neoadjuvant chemotherapy combined with anlotinib in occult breast cancer:A case report and review of literature显示文摘BACKGROUND Occult breast cancer(OBC)is a special type of breast cancer presenting as axillary lymph node metastasis with undetectable primary lesions in the breast.Due to its low incidence and unique clinical manifestations,there is a lack of consensus on the diagnosis and treatment of OBC.We report a case of OBC treated with neoadjuvant chemotherapy combined with anlotinib.The treatment was well tolerated,and the patient achieved a pathologic complete response.CASE SUMMARY A 53-year-old woman presented with a lump in her right axillary area with no primary lesions in the breast.Pathological biopsy confirmed right axillary metastatic carcinoma.Immunohistochemical staining results were positive for progesterone receptor,cytokeratin 7,specific breast markers GATA3 and gross cystic disease fluid protein-15.Tumor cells were negative for estrogen receptor,human epidermal growth factor receptor-2,cytokeratin 5/6,cytokeratin 20,and villin.The patient was diagnosed with OBC,and she underwent neoadjuvant chemotherapy combined with anlotinib.Mastectomy plus axillary lymph node dissection was performed.The patient achieved pathologic complete response with no residual invasive tumor cells in the breast or axillary lymph nodes.Postoperatively,she received adjuvant radiotherapy and endocrine therapy.CONCLUSION Neoadjuvant chemotherapy and anlotinib had good efficacy and safety in the treatment of OBC and may be a new therapeutic option. | Yu Zhang Di Wu Bo Zhao Xue-Liang Tian Tian-Cheng Yao Feng Li Wei-Fang Liu Ai-Ping Shi | 2021 | World Journal of Clinical Cases2021，9，4： | 3 |
| 16 | Artificial intelligence in gastric cancer:applications and challenges显示文摘Gastric cancer(GC)is one of the most common malignant tumors with high mortality.Accurate diagnosis and treatment decisions for GC rely heavily on human experts’careful judgments on medical images.However,the improvement of the accuracy is hindered by imaging conditions,limited experience,objective criteria,and inter-observer discrepancies.Recently,the developments of machine learning,especially deep-learning algorithms,have been facilitating computers to extract more information from data automatically.Researchers are exploring the far-reaching applications of artificial intelligence(AI)in various clinical practices,including GC.Herein,we aim to provide a broad framework to summarize current research on AI in GC.In the screening of GC,AI can identify precancerous diseases and assist in early cancer detection with endoscopic examination and pathological confirmation.In the diagnosis of GC,AI can support tumor-node-metastasis(TNM)staging and subtype classification.For treatment decisions,AI can help with surgical margin determination and prognosis prediction.Meanwhile,current approaches are challenged by data scarcity and poor interpretability.To tackle these problems,more regulated data,unified processing procedures,and advanced algorithms are urgently needed to build more accurate and robust AI models for GC. | Runnan Cao Lei Tang Mengjie Fang Lianzhen Zhong Siwen Wang Lixin Gong Jiazheng Li Di Dong Jie Tian | 2022 | Gastroenterology Report2022，10，1： | 3 |
| 17 | Characterization and biodegradation kinetics of a new cold-adapted carbamazepine-degrading bacterium, Pseudomonas sp. CBZ-4显示文摘Carbamazepine is frequently detected in waters and hardly eliminated during conventional wastewater treatment processes due to its complicated chemical structure and resistance to biodegradation. A carbamazepine-degrading bacterium named CBZ-4 was isolated at a low temperature(10°C) from activated sludge in a municipal wastewater treatment plant. Strain CBZ-4, which can use carbamazepine as its sole source of carbon and energy, was identified as Pseudomonas sp. by the 16S rRNA gene sequence. The composition and percentage of fatty acids, which can reveal the cold-adaptation mechanism of strain CBZ-4, were determined. Strain CBZ-4 can efectively degrade carbamazepine at optimal conditions: pH 7.0, 10°C, 150 r/min rotation speed, and 13% inoculation volume. The average removal rate of carbamazepine was 46.6% after 144 hr of incubation. The biodegradation kinetics of carbamazepine by CBZ-4 was fitted via the Monod model. Vmax and Ks were found to be 0.0094 hr 1and 32.5 mg/L, respectively. | Ang Li Rui Cai Di Cui Tian Qiu Changlong Pang Jixian Yang Fang Ma Nanqi Ren | 2013 | Journal of Environmental Sciences2013，25，11： | 2 |
| 18 | Divergent Primary Immune Responses Induced by Human Immunodeficiency Virus-1 gp120 and Hepatitis B Surface Antigen Determine Antibody Recall Responses显示文摘The development of a vaccine based on human immunodeficiency virus type 1(HIV-1) envelope glycoprotein(Env) that elicits potent protective antibodies against infection has been challenging. Recently, we compared the antibody production patterns of HIV-1 Env gp120 and hepatitis B virus surface antigen(HBsAg) to provide insights into how we may improve the protective efficacy of Env-based immunogens. Our previous study showed that HIV Env and HBsAg display different mechanisms of antibody elicitation and that T cells facilitate the responses to repeated immunizations. Here, to elucidate the detailed roles of primary immunization in immune memory response formation and antibody production, we immunized C57BL/6 mice with each antigen and evaluated the development of T follicular helper(Tfh) cells, germinal centers,and the memory responses involved in prime and boost immunizations. We found that after prime immunization, compared with HBsAg, gp120 induced higher frequencies of Tfh cells and programmed death(PD)-1^+T cells, greater major histocompatibility complex II expression on B cells, comparable activated B cells, but weaker germinal center(GC)reactions and memory B cell responses in the draining lymph nodes, accompanied by slower antibody recall responses and poor immune memory responses. The above results suggested that more PD-1^+T cells arising in primary immunization may serve as major contributors to the slow antibody recall response elicited by HIV-1 Env. | Li Yuan Wen-Jiang Chen Jia-Ye Wang Yan Li Dan Tian Ming-Xia Wang Hao-Tong Yu Ying-Chu Xu Di Li Min Zhuang Hong Ling | 2018 | Virologica Sinica2018，33，6： | 2 |
