| 2 | Induction of cytotoxic T lymphocyte respones in vivo after immunotherapy with dendritic cells in patients with nasopharyngeal carcinoma显示文摘The aim of the present study was to determine the efficacy of immunotherapy with dendritic cells to elicit EBV-specific CTL-immunity in advanced cases of EBV-positive patients with nasopharyngeal carcinoma (NPC) and to determine the safety and toxicity of this preparation. Nine cases of histologically confirmed patients with NPC undergoing treatment with radiological therapy were enrolled in this study. Dendritic cells, generated in vitro from blood monocytes of patients were cultured and matured with cytokines and then infected with recombinant adenovirus vaccine containing EBV-latent membrane protein-2 (Ad-LMP2). On 9 days' cultivation of cells, the matured DCs were harvested, irradiated with Co and then injected intradermally to patients with NPC. The injections were performed 3 times totally. After immunization, the CTL responses were assayed by means of cytotoxicity and epitope-specific IFN-γproduction. The results of this trial showed that all patients could tolerate this kind of treatment without any side effect, during which marked increase of LMP2-specific CTL-responses could be demonstrated in 5 patients of this group. And the level of IgA/VCA antibody decreased in 8 of 9 patients, thus accounting for a better prognosis for these patients. All patients will be followed up for another one year. At least, the present work shows that intradermal vaccination with autologous DCs infected with recombinant Ad-LMP2 adenovirus is a safe procedure in NPC patients, in which this procedure can enhance the LMP2-specific CTL responses in patients. These data are encouraging to develop more effective vaccine strategies for the treatment of nasopharyngeal carcinoma. | JIAN MIN ZUO LING ZHOU ZHI JIAN CHEN DE RUI LI QI WANG JIONG YU CHEN ZHAN WANG SI-IU QING WE YI ZENG | 2006 | Journal of Microbiology and Immunology2006,4,1: | 7 |
| 3 | Construction of the Eukaryotic Expression Vector for Outer Membrane Protein Tp92 from Treponema pallidum and Its Preliminary Study on the Immune Responses in New Zealand Rabbits显示文摘To construct the recombinant plasmid of eukaryotic expression containing Tp92 gene from Treponema pallidum and study its immunogenicity in New Zealand white rabbits. Tp92 gene was amplified from the genomic DNA of T. pallidum by polymerase chain reaction (PCR) and subcloned into appropriate site of pcDNA3.1(+) vector. After identification by sequencing and restrictive enzyme digestion, the recombinant plasmid was transfected into HeLa cells using liposome, and the expressed protein was identified by immunocytochemistry and Western blotting. After verifying that the Tp92 antigen gene fragment could be expressed in HeLa cells, 100?μg of recombinant plasmids [pcDNA3.1(+)-Tp92], 100 μg of control plasmids [pcDNA3.1(+)] or 0.5 ml PBS buffer were administered in 3 groups of New Zealand white rabbits (6 rabbits/group), and the booster immunizations were employed at 2-week interval for 3 times. ELISA assay was used for the quantitative detection of the specific antibody in the sera of rabbits, and the proliferation response of spleen cells was detected by MTT assay. It was found that the target gene Tp92 segment about 2103 bp was obtained, and the DNA sequence of Tp92 gene constructed in pcDNA3.1 (+) vector was consistent with the published nucleotide sequence. The homologies of the nucleotide and putative amino acid sequences of Tp92 gene between T.pallidum subsp. pallidum Nichols and various pathogenic treponeme strains were 95.5%-100%. The analysis of immunocytochemistry and Western blotting showed that Tp92 gene segment constructed in pcDNA3.1(+) vector could express a fusion protein with a calculated molecular mass of 77 kDa in HeLa cells and the expressed protein could react with positive blood serum from syphilis patient. The specific antibody IgG titers were observed and the highest titer was 1∶1024 in rabbits after 3 times with pcDNA3.1(+)-Tp92. The proliferation response of spleen cells were significantly higher than that of rabbits injected with pcDNA3.1(+) ( P <0.05). The successful expression of the eukaryotic expression plasmid of Tp92 gene from T. pallidum was obtained in eukaryotic system and strong responses of humoral and cellular immunity was evoked by DNA vaccine of pcDNA3.1(+)-Tp92 in rabbits thus establishing a solid basis for the future studies in the biological activities and for the development of the syphilis DNA vaccine. | 赵飞骏 吴移谋 刘双全 余敏君 | 2004 | Journal of Microbiology and Immunology2004,2,3: | 7 |

| 6 | Tumor Antigen Specific Activation of Primary Human T-Cells Expressing a Virally Encoded Chimeric T-Cell Receptor Specific for p185HER2显示文摘We have developed and tested chimeric T-cell receptors (TCR) specific for p185HER2. In these experiments, retroviral vectors expressing the N29γ or N29ζ receptors were constructed in pRET6. Amphotropic viral producer cells were established in the GALV-based PG13 packaging cell line. Ficoll purified human peripheral blood lymphocytes (PBL) were virally transduced using an optimized protocol incorporating activation with immobilized anti-CD3/anti-CD28 monoclonal anti- bodies, followed by viral infection in the presence of fibronectin fragment CH296. Transduced cells were co-cultured with human tumor cell lines that overexpress (SK-OV-3) or underexpress (MCF7) p185HER2 to assay for antigen specific im- mune responses. Both CM+ and CD8+ T-cells transduced with the N29γ or N29ζ chTCR demonstrated HER2-specific anti- gen responses, as determined by release of Th1 like cytokines, and cellular cytotoxicity assays. Our results support the fea- sibility of adoptive immunotherapy with genetically modified T-cells expressing a chTCR specific for p185HER2. | 杨建民 Michael S FRIEDMAN Christopher M REYNOLDS Marianne T HUBEN Lee WILKE Jennifer FULLER 李桥 Zelig ESHHAR James J MULE Kevin T MCDONAGH | 2004 | Journal of Microbiology and Immunology2004,2,4: | 5 |

| 8 | The expression of PD-1 and level of CXCL10 in patients with systemic lupus erythematosus显示文摘The aim of this study was to investigate the expression of PD-1 on peripheral blood mononuclear cells (PBMCs) and the serum level of CXCL10 and those of roles in the pathogenesis in SLE patients. The expression of PD-1 on PBMCs was tested by flow cytometry and the serum level of CXCL10 was determined by ELISA in 47 SLE patients and 21 healthy controls. The correlation between PD-1, CXCL10 and ANA, anti-dsDNA antibody and SLEDAI (SLE disease activity index) were evaluated. The expression of PD-1 on PBMCs in SLE patients was significantly different from that of controls. The percentage of PD-1 on neutrophiles in SLE patients was decreased compared with that of healthy controls (P<0.01), and that on lymphocyte from inactive SLE was significantly lower than that of controls (P<0.02). However, the PD-1 expression and the level of serum CXCL10 in active SLE were significantly increased (P<0.01) than those of controls. Positive correlations were found between PD-1, CXCL10 and anti-dsDNA antibody, SLEDAI in active SLE. The abnormal expression of PD-1 on PBMCs and serum level of CXCL10 in SLE patients may impair the auto-immunological tolerance, and play an important role in the pathogenesis of SLE. | YING NAN LI FENG SHAN ZHANG LU LU LI HUI MIN YU YING KUN NIE | 2005 | Journal of Microbiology and Immunology2005,3,3: | 4 |
| 9 | Fluorescence-based Multiplex PCR-Single Strand Conformation Polymorphism (SSCP) Analysis of 16S Ribosomal DNA Using Capillary Electrophoresis显示文摘The rRNA genetic locus is found in all prokaryotic organisms, and is highly conservative, although its relatively stable variations are found frequently in different bacteria. The utility of this locus as a taxonomic and phylogenetic tool has been reported widely. This study, aimed at 16S rRNA gene (16S rDNA) and with the help of biomolecular methods, attempted to achieve the goal of rapid identification of common pathogens. In this study, 333 clinical isolated pathogenic bacteria were collected. Two pairs of primers were chosen and labeled with different fluorescent dyes and then used to amplify the genomic DNA extracted from bacteria. The PCR products were then detected by capillary electrophoresis-single strand conformation polymorphism (CE-SSCP). In order to pursue higher resolution and peak-separation effect, a high efficient separating medium, liner polyacrylamidedel (LPA), was put to use in this study. Finally, every bacteria colony generated distinct patterns from each other, which were easily to be used for identification. These results indicated that PCR-CE-SSCP was a rapid identification method for bacterial identification, with the aspects of high efficiency and high precision. Compared with traditional method, this technology is of great utility for clinical use especially for its high sensitivity. | 高鹏 韩英 许国旺 赵春霞 戴兵 李萍 王运铎 温杰 徐维家 | 2004 | Journal of Microbiology and Immunology2004,2,2: | 4 |

| 11 | Isolation and Characterization of Exosomes Derived from Tumor Cells Genetically Expressing Model Antigen显示文摘Tumor cell-derived exosomes have been proposed as non-cellular nanomeric vaccine which could induce potent anti- tumor immune response in mice. In order to develop the protocols to prepare tumor cell-derived exosomes for basic research and clinical trail, we isolated exosomes from ovalbumin (OVA)-expressing thymoma cells EG.7-OVA by various preparation methods. We demonstrate the non-sedimentation method is simple, rapid, efficient with higher yield and purity of exosomes. EG.7-OVA-derived exosomes are 40-100 nm in diameter sequestered by lipid bi-layer, and contain rich heat shock protein (HSP) and OVA. The result of the size distribution determination is consistent with the calculation by the visual microscopic inspection, with 90.4% particles at the range of 50-90 nm. Moreover, as a model antigen of the EG.7 cells, OVA concentra- tion in EG.7-derived exosomes can be regarded as a good quality control parameter. Therefore, we have established a platform to efficiently prepare exosomes for tumor immunotherapy. | 修方明 杨云山 蔡志坚 王建莉 曹雪涛 | 2004 | Journal of Microbiology and Immunology2004,2,4: | 4 |

| 13 | Hepatoprotective ability of tetramethylpyrazine produced by Bacillus amyloliquefaciens显示文摘Tetramethylpyrazine(TTMP),an important aroma compound,was produced by Bacillus amyloliquefaciens XJB-104 with distillers’grains as raw material.The yield of TTMP under optimized fermentation procedure was 3176.52 mg/L.TTMP in the fermentation broth was purified and the purity(>99%)was measured by gas chromatography-mass spectrometry.Furthermore,the hepatoprotective activity of TTMP in ethanol-water system was evaluated by biochemical indicators of liver injury,parameters of antioxidant defense system and inflammatory response,and liver histopathological assessment in mice.Ethanol treatment increased serum levels of alanine aminotransferase,aspartate aminotransferase,alkaline phos-phatase and lactate dehydrogenase,suggesting liver damage.Both high and low dose of TTMP significantly decreased levels of these indicators.Furthermore,the reduction in the activities or concentrations of superoxide dismutase,catalase,reduced glutathione and malondialdehyde in liver tissue caused by ethanol was significantly alleviated by TTMP.Increased inflammatory cytokines including transcription factor,tumor necrosis factor,interleukin-1beta,interleukin,macrophage chemoattractant protein,inducible nitric oxide synthase and cyclooxygenase were also suppressed by TTMP treatment.It is concluded that TTMP in ethanol-water system has potential liver-protective activity,especially when ethanol is consumed at low doses for short periods of time. | Wenqing Zhang Guanru Si Zhiming Rao Shuai Zong Jinglei Li Xian Zhang Chuanqiang Gao Zhou Ping Ming Ye | 2021 | Systems Microbiology and Biomanufacturing2021,1,2: | 4 |
| 14 | Polymorphism in the upstream regulatory region of human papilloma virus type 16 from the cervical cancer biopsies in Xinjiang Uygur women显示文摘To investigate the mutations in the upstream regulatory region (URR) of human papillomavirus type 16 (HPV-16) from the cervical cancer biopsies in Xinjiang Uygur women and its relationship to the high incidence of cervical cancer in the southern Xinjiang, the tissue DNA was extracted from the cervical cancer biopsies, and the URR segment of HPV-16 DNA was amplified, sequenced and analyzed. Thereafter, the polymorphism of URR in HPV-16 was then analyzed. It was demonstrated that the positive rate detected for the presence of URR in HPV-16 was 89.47% (17/19). Compared with the previously published sequence in URR of prototype HPV-16, some mutations were detected in the sequence of URR. The mutations in 17 URR fragments of HPV-16 could be divided into 11 patterns (XJU-1 to XJU-11) at nucleic acid level, in which each of XJU-1 and XJU-4 accounted for 23.53% (4/17), and other patterns of mutation accounted for 5.88% (1/17) . In comparison with the URR of prototype HPV-16, the DNA identity of these patterns was 98.50%-99.68% . In these 17 URR fragments, two point mutations occurred at position 7192 (G to T) and position 7520 (G to A) and they appeared to be constant in Xinjiang area. These two mutations were ubiquitous in the Asia-American type and conferred strong infection activity and carcinogenicity of this virus. In addition, the mutations at position 7729 (A to C), position 7843 (A to G) and position 7792 (C to T) could enhance its transcription activity considerably. It is concluded that some mutations occur in URR gene of HPV-16 in the cervical cancer biopsies taken from Uygur women in Xinjiang area, suggesting that certain relationship exists among the mutations in URR of HPV-16, the phylogeny of HPV-16 and the high incidence of cervical cancer in southern part of Xinjiang area. | MENG YU ZHENG HAI MA YAN PIN WANG XI DAN RE FU CHUN ZHANG | 2006 | Journal of Microbiology and Immunology2006,4,3: | 4 |
| 15 | Quality control and evaluation of human immunodeficiency virus antibody assays used for screening donated blood in China显示文摘During 2004, a total of 124 batches of HIV antibody ELISAs from domestic and overseas manufacturers, comprising approximately 60 million tests, were tested for quality and released for screening blood in China. The inter- and intra-batch variation, specificity, and sensitivity were evaluated using a laboratory panel and clinical samples. The inter-batch variation was less than 15% and only 2 of 12 assays had intra-batch variation of less than 20% for 4 dilutions of a control specimen. 257 samples confirmed positive for HIV antibody and 4826 negative samples from different regions in China were used to evaluate the sensitivity and specificity of the assays. The results showed that the sensitivity is in the range from 93.7% to 100% for assays sampled directly from the manufacturers, and 91. 4%-99. 6% for those retrieved from the consumers; the specificity was in the range from 97.88% to 99.97% . The testing environment may vary in different regions of China. Therefore, manufacturers should provide robust assays to satisfy the requirements of these diverse environments, and especially reduce the intra-assay variation and improve the stability of the kits. | You CHUN WANG XIU HUA LI AI JING SONG CHUN TAO ZHANG SI HONG XU FENG ZHANG HONG ZHANG YIN | 2006 | Journal of Microbiology and Immunology2006,4,1: | 4 |

| 18 | Exosomes in the Immune Response and Tolerance显示文摘Exosomes, secreted by many live cells, are small non-cell vesicles with nanoparticle-grade size. In addition to the original function of discarding the uselessful membrane molecules, exosomes are involved in a range of immunoregulatory functions. Dendritic cell-derived exosomes and tumor-derived exosomes are the best characterized vesicles with potent anti- tumor effect by efficiently inducing immune response. Down-regulation of immune response or induction of immune tolerance is another interesting function of exosomes. Further functional studies of the exosomes will shed light on the application of exosomes. | 修方明 曹雪涛 | 2004 | Journal of Microbiology and Immunology2004,2,4: | 3 |

| 20 | PI3-K/PKB/NF-κB and p42/44 MAPK pathway mediates inhibition of lipoxin A_4 on CTGF-induced production of RANTES in mesangial cells显示文摘In order to investigate the regulatory role of connective tissue growth factor (CTGF) on production of RANTES (regulated on activation, normal T cell expressed and secreted) in rat glomerular mesangial cells, and the modulatory effect of lipoxin A4(LXA4) on action of CTGF, and to explore the mechanisms of action of CTGF and LXA4, cultured rat mesangial cells were treated with CTGF, with or without preincubation with LXA4. Expression of mRNA was analyzed by RT-PCR. Protein of RANTES in the supernatants was determined by ELISA. Monocyte transmigration was assessed by in vitro chemotaxis assay. Expression of p42/44 mitogen-activated protein kinase (MAPK), phosphoinositide 3-kinase (PI3-K) and protein kinase B (PKB) was assessed by Western blotting. DNA-binding activity of nuclear factor-κB (NF-κB) was determined by electrophoretic mobility shift assay (EMSA). To observe whether transfection of LXA4 receptor homologue gene (LRHG) into mesangial cells intensified these modulatory effects of LXA4, mesangial cells were transfected with pcDNA3.1/LRHG vector. The results showed that CTGF enhanced the mRNA expression and protein release of RANTES, and the expression of phospho (P)-p42/44 MAPK, P-PI3-K, P-PKB and NF-κB. P-p42/44 MAPK blockade inhibited the CTGF-induced expression of P-p42/44 MAPK and partially decreased the level of RANTES in supernatants. P-PI3-K blockade downregulated the CTGF-stimulated expression of P-PI3-K, P-PKB and NF-κB, and partially decreased the release of RANTES. NF-κB blockade abrogated the CTGF-activated NF-κB and partially decreased the secretion of RANTES. LXA4 dose-dependently inhibited the CTGF-stimulated above action. Transfection of LRHG into mesangial cells intensified these inhibitory effects of LXA4 on CTGF-induced release of RANTES and expression of the P-p42/44 MAPK. In conclusion, LXA4 inhibits CTGF-induced production of RANTES via PI3-K/PKB/NF-κB and p42/44 MAPK-dependent signal pathway, which is mediated by LRHG in rat mesangial cells. | SHENG HUA WU CHAO LU LING DONG Guo PING ZHOU XIN You JIANG | 2005 | Journal of Microbiology and Immunology2005,3,3: | 3 |
