摘要:
目的:观察护卵汤对慢性应激超排卵小鼠卵巢转化生长因子β(TGF-β)/Smads信号通路相关蛋白表达的影响。方法:建立慢性应激小鼠模型,将模型小鼠随机分为中药(护卵汤)组、西药(生长激素+阿司匹林)组和模型组,并设正常组。模型组和正常组给予0.9%氯化钠溶液,治疗组给予相应的药物。在超排卵后第3天处死小鼠10只;注射绒毛膜促性腺激素(HCG)24h后处死余下小鼠取卵巢。Western Blot检测卵巢TGF-β1、 P-Smad3及卵泡刺激素受体(FSHR)蛋白表达。结果:模型组卵巢TGF-β1、P-Smad3及FSHR蛋白表达较正常组同期均显著降低(P<0.05)。与模型组同期比较,中药组和西药组卵巢TGF-β1、P-Smad3及FSHR蛋白表达均明显升高(P<0.05);且中药组与西药组同期比较升高更明显(P<0.05)。结论:护卵汤可促进慢性应激小鼠卵巢功能的恢复,其机制可能与调控TGF-β/Smads信号通路相关蛋白表达有关。

摘要:
医学免疫学是基础医学中最抽象、难懂的一门学科,如何提高课堂教学效果和教学质量,一直是教学改革的方向。课前预习可有效提高教学效果和质量,但在大学教育中由于没有相应的督促措施与评价手段,学生预习效果往往并不理想。将课前预习与小讲课相结合应用于医学免疫学教学,有利于保证知识的系统性和连贯性,从而提高教学质量。

摘要:
Peptides, bound to the tegument of live Schistosoma japonicum schistosomula, were differentially screened by phage display in vitro using three rounds of reverse absorption and bio-panning. Three M13 phage peptides were isolated and identified by determination of their recovery rate, immunohistochemical localization, immunoblot analysis, and their anti-schistosomal effects in vivo and in vitro. Of the three, M13 phage peptide ZL4 (MppZL4, YSGLQDSSLRLR, 1.4 kDa, pI 8.8) bound to the tegument of mechanically transformed schistosomula and to other developmental stages of S. japonicum from the mammalian host. By contrast, MppZL4 did not bind to the surface of cercariae. To further examine its binding properties, MppZL4 was conjugated to Rhodamine B (RhB-YSGLQDSSLRLR, RhB-ZL4) and a peptide control (RhB-AIPYFSGILQWR, RhB-12P) was similarly synthesized. The binding capacities of RhB-ZL4 to the surface membrane of S. japonicum schistosomula in vitro and of S. japonicum adult worms in vivo were examined and revealed specificity for binding. When examined for anti-parasite activity, both MppZL4 and RhB-ZL4 exhibited a potent schistosomicidal effect in vitro. Further MppZL4 also affected the growth and development of schistosomula in vivo. These findings extend previous studies showing that phage display techniques can recover polypeptides that bind specifically to living schistosomes and, moreover, that these bound peptides have the potential to inhibit key physiological processes in these parasites. Our findings suggest further that ectogenic polypeptides, which can bind to the tegument of S. japonicum, might be adapted as vectors to deliver experimental probes and/or pharmacologically relevant compounds to the schistosome tegument, including drugs and immunological mediators. © 2011 2011 Elsevier B.V.

摘要:
Retroviral transduction of cultured schistosomes was explored in our study. The vesicular stomatitis virus glycoprotein (VSVG)-pseudotyped pantropic retroviral vector pBABE-puro was modified to incorporate the human telomerase reverse transcriptase gene (hTERT) as a reporter gene under the control of retroviral long terminal repeat (LTR). Pseudotyped virions were employed to transduce Schistosoma japonicum (Sj) to investigate the utility of retrovirus mediated Sj transgenesis and to investigate the activity as human telomerase as a reporter transgene in schistosomes. The presence of transgene hTERT was detected by PCR. Furthermore, analysis of RNAs from transduced parasites, immunohistochemistry of thin sections and immunoblot analysis revealed expression of hTERT transgene in the transduced worms. These findings indicated that Sj could be effectively transduced by VSVG pseudotyped retrovirus carrying the hTERT gene.

摘要:
Although draft genome sequences of two of the major human schistosomes, Schistosoma japonicum and Schistosoma mansoni are available, the structures and characteristics of most genes and the influence of exogenous genes on the metabolism of schistosomes remain uncharacterized. Furthermore, which functional genomics approaches will be tractable for schistosomes are not yet apparent. Here, the vesicular stomatitis virus glycoprotein (VSVG)-pseudotyped pantropic retroviral vector pBABE-puro was modified to incorporate the human telomerase reverse transcriptase gene (hTERT) as a reporter, under the control of the retroviral long terminal repeat (LTR). Pseudotyped virions were employed to transduce S. japonicum to investigate the utility of retrovirus-mediated transgenesis of S. japonicum and the activity of human telomerase reverse transcriptase as a reporter transgene in schistosomes. Schistosomules perfused from experimentally infected rabbits were cultured for 6 days after exposure to the virions after which genomic DNAs from virus exposed and control worms were extracted. Analysis of RNA from transduced parasites and immunohistochemistry of thin parasite sections revealed expression of hTERT in the transduced worms. Expression of hTERT was also confirmed by immunoblot analysis. These findings indicated that S. japonicum could be effectively transduced by VSVG-pseudotyped retrovirus carrying the hTERT gene. Given the potential of hTERT to aid in derivation of immortalized cells, these findings suggest that this pantropic retroviral approach can be employed to transduce cells from specific tissues and organs of schistosomes to investigate the influence of transgene hTERT on growth and proliferation of schistosome cells. © 2010 Elsevier B.V.

摘要:
目的 探讨用双嗜性逆转录病毒载体将外源基因导入日本血吸虫(Sj)细胞的生物学理论与实验依据. 方法 用生物信息学方法对双嗜性逆转录病毒rRam-1受体同源性分布、结构与功能作系统的分析与比较;利用携带外源E77.43基因的双嗜性逆转录病毒感染Sj童虫培养细胞,经PCR和RT-PCR检测感染细胞目的 基因(E77.43)的整合与表达. 结果 根据生物信息学分析结果推断,Sj细胞膜上存在的SiCHGC09605和SjCHGC05362两种蛋白为非分泌性跨膜蛋白,可能具有细胞膜离子转运通道或受体蛋白的功能及双嗜性逆转录病毒感染的膜受体样作用,可能参与病毒对细胞的吸附和穿入过程;利用携带外源E77.43基因的双嗜性逆转录病毒感染Sj童虫培养细胞后.用PCR及RT-PCR检测到目的 基因整合与表达,扩增的目的 片段大小为330 bp,与理论值相符. 结论 用载有E77.43基因的双嗜性逆转录病毒感染Sj童虫细胞获得成功,推测SiCHGC09605和SjCHGC05362两种与rRam-1受体同源的蛋白可能是Sj感染过程中起作用的分子.研究结果为下一步用双嗜性逆转录病毒载体转导永生化基因到Sj细胞提供了生物学理论与实验依据.
