查询词典 antigen

Antigen of hepatitis B surface is electropositive person the 8%~10% that occupies our country population.

The heterologous protein fragments are so-called CTL epitope, which is the linear fragment or the space conformation structure recognized specifically by immune cell and plays a key role in CTLs activation. It is the elementary event of inducing immune responses and it decides CTL specific cytotoxic effects, therefore, selection of antigen epitope makes the pivotal step to identification of specific antibodies.

No TSHR protein was found in the healthy subjects. Conclusion High TSHR expression in the EOM of TAO patients indicates that as a common antigen between the orbit and thyroid, TSHR play a key role in the pathogenesis of TAO.

TSHR蛋白TAO患者眼外肌组织中有表达，而在正常个体中没有表达，证实TAO患者球后眼外肌组织中存在有活性的TSHR蛋白，提示TSHR可能作为交叉抗原在TAO发病机制中起重要作用。

Coclusion These results demonstrated that the rSpaA-N is a protective antigen of Erysipelothrix rhusiopathiae serotype 2 strains, and might be a useful vaccine candidate against swine erysipelas.

本研究结果表明rSpaA-N具有良好的免疫保护作用，可以作为猪丹毒亚单位疫苗。

Compared with classical cytotoxic T lymphocytes , NK cells are superior in the following aspects: NK cells are among the first cell types to be activated after intracellular pathogen stimuli, the activity of NK cells peaked between 1 to 3 days, retained during the first 7-10 days, and the T cells response emerged only after 7 days when the NK cell responses begin to decline; though comprising of only 10％-15％ of peripheral lymphocytes, NK cells mobilize most of the cell populations in a strong and high level response to different invasions, and act as key factors at early defense before a specific immune response could mount, while only certain clones were involved in T cell response; NK cells kill virus-infected or malignant transformed cells without pre-sensitization and without restriction by major histocompatibility antigen, which is usually a mechanism of immune escape to T cell recognition by virus-infected or tumor cells, thus NK cell in complementary with T cells play crucial roles in tumor and virus eradication.

NK细胞以其强大的细胞毒活性为特征，与细胞毒性T细胞相比，NK细胞具有如下特点：NK细胞虽然只占外周血淋巴细胞的10-15％，但是对刺激性因素产生应答的过程十分迅速，一次可以调动大多数细胞共同参与，而不是几个克隆的活化，免疫应答的强度高；病毒感染或恶性转化细胞的一个主要特征是细胞表达的MHCⅠ类分子下降或消失，并借助这一机制逃避特异性T细胞应答的识别，NK细胞介导的杀伤活性无需抗原刺激，不受MHCⅠ分子表达的限制，从而与T细胞应答互为补充发挥免疫防御的功能；NK细胞的免疫活性可以被多种细胞因子上调，其中IFNα，IL-2，IL-12，IL-15和IL-18具备更强的作用；NK细胞具有强大的细胞因子分泌功能，对于启动T细胞特异性应答必不可少。

Aiming at the currently shortage of XML streams quality detecting, this paper proposes a new forecasting method of XML streams quality by least squares support vector machines, which is used the method of XML keys' vector matrix as windows, and vector product wavelet transform to multilevel decompose and refactor the XML streams series, that can fulfill real-time checking demand of XML quality, and ensure constraint, consist- ency and integrality. For even more adapting net load, it proposes a control strategy by weight and adaptive adjustment to ensure XML streams quality.

针对当前XML数据流质量检测存在的不足，提出构建XML键的矢量矩阵作为窗口，利用矢量积小波变换多级分解与重构XML数据流，再结合最小二乘支持向量机对XML数据流质量进行预测的一种方法，满足XML数据流质量重构时实时检测的要求，保证XML数据的约束性、一致性与完整性；为了更好的适应网络负载，采取加权与自适应窗口调整等调度策略充分保证XML数据流的质量检测。
