| 1 | Opiate-induced constipation related to activation of small intestine opioid μ2-receptors显示文摘AIM:To investigate the role of opioid μ-receptor subtype in opiate-induced constipation (OIC).METHODS:The effect of loperamide on intestinal transit was investigated in mice.Ileum strips were isolated from 12-wk-old male BALB/c mice for identification of isometric tension.The ileum strips were precontracted with 1 μmol/L acetylcholine (ACh).Then,decrease in muscle tone (relaxation) was characterized after cumulative administration of 0.1-10 μmol/L loperamide into the organ bath,for a concentration-dependent study.Specific blockers or antagonists were used for pretreatment to compare the changes in loperamide-induced relaxation.RESULTS:In addition to the delay in intestinal transit,loperamide produced a marked relaxation in isolated ileum precontracted with ACh,in a dose-dependent manner.This relaxation was abolished by cyprodime,a selective opioid μ-receptor antagonist,but not modified by naloxonazine at a dose sufficient to block opioid μ-1 receptors.Also,treatment with opioid μ-1 receptor agonist failed to modify the muscle tone.Moreover,the relaxation by loperamide was attenuated by glibenclamide at a dose sufficient to block ATP-sensitive K + (K ATP) channels,and by protein kinase A (PKA) inhibitor,but was enhanced by an inhibitor of phosphodiesterase for cyclic adenosine monophosphate (cAMP).CONCLUSION:Loperamide induces intestinal relaxation by activation of opioid μ-2 receptors via the cAMPPKA pathway to open K ATP channels,relates to OIC. | Wency Chen Hsien-Hui Chung Juei-Tang Cheng | 2012 | World Journal of Gastroenterology2012，18，12： | 20 |
| 2 | Identification of immunodominant linear B-cell epitopes within the major outer membrane protein of Chlamydia trachomatis显示文摘Chlamydia trachomatis 是最流行的性播送的病原体之一。Chlamydial 主要的外部膜蛋白质(MOMP ) 能在鼠科的模型导致强壮的细胞、体液的有免疫力的回答并且被认为是一个潜在的疫苗的候选人。在这份报告, MOMP 的氨基酸顺序用帮助计算机的技术被分析扫描 B 房间 epitopes,和三可能的线性 B 房间 epitopes 肽(VLKTDVNKE, TKDASIDYHE, TRLIDERAAH ) 与高预言的 antigenicity 和高度,保存被调查。为各潜在的 epitope 编码区域的 DNA 被克隆进 pET32a (+) 并且在 Escherichia coli 表示了为 Trx-His-tag 熔化蛋白质。熔化蛋白质被 Ni-NTA agarose 祷告净化并且由 SDS 页和西方的污点分析列在后面。我们与这三熔化蛋白质使老鼠免疫。从使免疫的老鼠包含 anti-epitope 抗体的 sera 能认出 C。在 ELISA 的 trachomatis serovars D 和 E。这些熔化蛋白质的 Antisera 在 serovar E 的侵略上显示了禁止的效果由在 vitro 中立化试金。另外,浆液从恢复健康的 C 取样。感染 trachomatis 的病人与由西方的污点试金的 epitope 熔化蛋白质是反应的。我们的结果证明生物信息的分析选择的 epitope 序列是高度保存的 C。trachomatis MOMP B 房间 epitopes,并且能是子单元疫苗的发展的好候选人,它能在临床的诊断被使用。 | Shanli Zhu Jun Chen Meixia Zheng Wenci Gong Xiangyang Xue Wenshu Li Lifang Zhang | 2010 | Acta Biochimica et Biophysica Sinica2010，42，11： | 11 |
| 3 | A multi-epitope vaccine based on Chlamydia trachomatis major outer membrane protein induces specific immunity in mice显示文摘我们评估了包括主要的外部膜蛋白质(MOMP ) 的一支候选人疫苗的 immunogenicity 和功效 multi-epitopeof Chlamydia trachomatis。从包含多重 T 房间和 B 房间 epitopes 的 MOMP 导出的 multi-epitope 的短基因是人工地,包含 codon 的 synthesized.The recombinant plasmid pET32a (+) 优化了 MOMP multi-epitope 基因被构造。在 Escherichia coli 的 fusionprotein Trx-His-MOMP multi-epitope 的表示被钠 dodecyl sulfatepolyacrylamide 胶化电气泳动和西方的污点分析证实。Balb/c 老鼠是 inoculatedwith 皮下地,三与 2 星期的间隔预定的净化的熔化蛋白质。结果出现了 MOMP multi-epitopeelicited 不仅对 C 的强壮的体液的有免疫力的回答。由显著地产生特定的抗体(IgG1 和 IgG2a ) 的高水平的 trachomatis,而且由 inducingrobust 的细胞的有免疫力的回答在老鼠的细胞毒素的 T 淋巴细胞回答。而且, MOMP multi-epitope 实质地告知 IFN- 的分泌物,表明这支疫苗能导致强壮的 Th1 回答。最后,老鼠与 C 的 MOMP multi-epitope displayeda 减小种牛痘。在 chlamydial 挑战和感染的 C 的一个加速的清理之上流的 trachomatis。trachomatis。在结论, MOMP multi-epitope 疫苗可以对 C 为有效预防 andtherapeutic 疫苗的发展有潜力。trachomatis 感染。 | Jianxin Tu B ailong Hou Bingbing Wang Xiaoyun Lin Wenci Gong Haiyan Dong Shanli Zhu Shao Chen Xiangyang Xue Kong-Nan Zhao Lifang Zhang | 2014 | Acta Biochimica et Biophysica Sinica2014，46，5： | 1 |
