查询词典 antigen

ANP and CX43 began to express at 2nd week after induction and increased gradually,about 60% of the resulting myogenic cells were positive at 4th week after induction ,they were negative for uninduced cells.hMSCs'surface antigen profiles obtained by Flow Cytometry were negative for CD31\CD34\CD45 before and after induction,but CD90 expressed higher after induction while was weak positive before induction(P.05). Apotosis index was correlated with the cultural time after induction,The apoptosis rate of induced hMSCs was remarkably higher than control group(P.01),and the variation between groups was notable(P.05),the cell cycle analysis showed that the percentages of G_0/G_1phases were reduced significantly after induction. The expresstion levels ofβ-MHC and CTNT mRNA were undetectable before induction,began to increase at 1st、4th week after induction,reached the peak at 6th week and decreased after that,the expression of Bcl-2 and Bax mRNA varied regularly after treated with 5-azacytidine. hMSCs'resting membrane potential、range and rate of depolarization were heightened gradually after being induced.

结果：hMSCs诱导前为纺锤形，诱导后第2天部分细胞即开始发生形变，呈球形或短棒状，1周后胞浆中颗粒增多，约20～30%细胞边缘呈毛刷样变化；hMSCs表面抗原CD31、CD34、CD45在诱导前后差异无统计学意义，CD90未诱导时表达呈弱阳性，诱导后明显增高(P.05)；ANP和CX43在诱导前无表达，诱导后第2周开始表达且表达随时间逐渐增强，但CX43在诱导后第5周表达量开始降低。hMSCs诱导后凋亡指数随诱导后培养时间增加，低浓度诱导组低于标准浓度诱导组，组间差异有统计学意义(P.05)，G_0/G_1期细胞比例诱导后较对照组显著减少(P.05)；β-MHC和CTNT基因分别在诱导后第1周和第4周时表达开始增强，在第6周时均达到高峰，第8周时表达开始衰减，Bcl-2、Bax基因表达呈时间依赖性变化，hMSCs经诱导后随心肌样细胞特征的表达膜静息电位、去极化幅值和去极化速率逐渐增高。

Among them, TLR2 and TLR4 recognize lipopolysaccharide and lipoproteins, respectively. TLR9, which is restricted to antigen presenting cells , is specific for unmethylated CpG oligodeoxynucleotides that are present in bacterial DNA.

其中TLR2和TLR4分别参与革兰氏阳性细菌肽聚糖和革兰氏阴性细菌脂多糖的识别，TLR9主要存在于抗原递呈细胞表面，特异识别存在于细菌基因组中的CpG motif。

METHODS Immuno-in situ PCR was used for detection of HCMV antigen in pregnant women cervix uteri exfoliated cells.

The prevalence of antibodies against HCV in hepatitis B surface antigen-negative patients is around 70-80%, and most of them are viremic.

C型肝炎病毒感染是本地慢性肝病的第二大原因，B肝表面抗原阴性的慢性肝炎息者中，70~80%为C肝抗体阳性，且多数体内存有病毒。

So overall the sequential add on strategy is a very good but rather complicated and expensive strategy that is working very well for centers and particularly in low viremic patients particularly in e antigen negative patients.

所以总的来说，序贯加用联合治疗方案是很好，但相当复杂、昂贵的方案。在各个中心对低病毒载量尤其是对HBeAg阴性的患者应用起来效果好。

Owing to the variability of HVR1, the method to check anti-HVR1 antibodies need to cloning and expressing the gene of HVR1 of every sera and that poses some problem. For example, it needs lots of time and money, and the sample must come from viremic patients. It is urgent to acquire a broadly cross-reactivity HVR1 antigen to check the antiHVR1 Ab in the sera of HCV infected patients by ELISA.

由于HVR1的高变性，因此要想测定血清中抗HVR1水平，通常要克隆表达待测血清中的HVR1基因，但该方法时间长、费用高，并仅对HCV、RNA阳性血清适用，所以急需一种具有极高交叉反应性的HVR1抗原，才可通过ELISA对病人的HVR1抗体进行检测。
