抗原

Introduction: Self tolerance is regarded as the anergy condition for the immune system to self antigens.

前言 自身免疫耐受是指机体免疫系统对自身抗原的无应答状态。

Inhibition of this pathway results in development of antigen-specific unresponsiveness and clonal anergy.

阻断该通路可以导致抗原特异性的免疫耐受和克隆不应答状态。

The lack of antigen-presenting cell activity of CB MNCs in primary mixed lymphocyte culture did not induce allogeneic T cell anergy.

缺乏抗原提呈细胞活性的脐带血单个核细胞在初级混合淋巴细胞培养下不能诱导同种异体反应T细胞的无反应性。

In the absence of appropriate costimulation, partial activation of T cells can be lead to a state of long-lasting antigen-specific unresponsiveness or anergy.

在TCR识别MHC-抗原肽的同时，B7和CD28分子对的共刺激作用将使T细胞增殖并上调细胞因子表达，启动免疫应答反应。

While the TCR engagement with specific antigen, the administration of CTLA-4Ig can induce T cell anergy in vitro or tolerance in vivo.

在TCR识别外来抗原的同时给予可溶性CTLA-4，在体外可诱导T细胞无应答，在体内则可诱导特异性免疫耐受。

To evaluate the short-period clinical outcome of CD34 expression and DNA aneuploid in acute leukemia.

观察具有CD34抗原表达和存在DNA非整倍体的急性白血病的短期临床疗效。

Objective To appraise the value on combined detection of telomerase activity,DNA aneuploid and carcinoembryonic antigen for the laboratory diagnosis of malignant pleural effusion.

目的评价联合检测胸腔积液中端粒酶活性、DNA异倍体和癌胚抗原对实验诊断恶性胸腔积液的价值。

Three groups were trendelenburg position and were at an angle of declination by 15,30,45 degree accordingly.

患者既往均无黄疸、胰腺炎、严重感染及免疫系统疾病史，术前检查心、肺、肝、肾功能均在正常范围，乙肝表面抗原阴性。

The typical pathological characteristics of SPTs may result from gradual degenerative changes induced anoxemia in some SPT's areas. The heterogeneity of SPTs on different antibody markers showed that the SPTs may be originated from pancreatic embryonic stem cells, and result from immature differentiation of the pluripotential stem cells during pancreatic genesis.

SPT典型病理特征是由于肿瘤组织不同区域相对缺血、缺氧所造成的退行性变的结果，SPT表达多种组织来源的抗原，反映其可能来源于胰腺干细胞及与其发育密切相关的胚胎神经嵴的神经前体细胞，且在发育过程中发生分化不成熟的结果。

Serum titers of antibody to HBV surface antigen were measured at 1, 3, and 12 months posttransplantation.

血清的HBV表面抗原的抗体滴度的测定则分别在移植后的1，3，12 月之后进行。

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
