All is a tumor in which immature white blood cells that normally develop into immune system cells , called b or t lymphocytes , instead multiply rapidly and overwhelm the normal blood cells the body needs to survive All是一种恶性肿瘤，在正常情况下应分化为免疫系统细胞（ b细胞和t淋巴细胞）的未成熟白细胞停止分化，并快速异常增值，使得血液中机体赖以生存的正常血细胞的数目急剧减少。
Our results showed that , in the activated mouse spleen t lymphocytes and self - proliferative jurkat cells , actin bound to brgl , nfl / ctf and rna polymerase ii during gene transcription . whereas , in unactivated mouse spleen t lymthocytes , no binding could be found 结果表明，在活化的小鼠脾t淋巴细胞和自主增殖的jurkat细胞中，肌动蛋白可以与mf复合物、转录因于nfi ctf和rna聚合酶11结合。
2 , immuno - co - precipitation showed that in the activated mouse spleen t lymphocytes and self - proliferative jurkat cells , brg1 , nf1 / ctf and rna polymerase ii were closely bound together , and this was not found in un - activated cells 2 、免疫共沉淀实验证明，在活化的小鼠脾t淋巴细胞和自主增殖的jurkat细胞中， brg1 、 nf1 ctf和rna聚合酶是紧密结合在一起的，在没有活化的小鼠脾t淋巴细胞中这三种蛋白质没有免疫共沉淀现象。
Following the 7d , 14d , 21d , 28d feeding period , in each treatment , one mouse was killed to count the ratio of peripheral anae + t lymphocyte , serum igg content , serum cu , zn - sod activity , serum cp activity , immune organ index , copper concentration in liver and spleen 在正式试验期第7天、 14天、 21天、 28天，每重复选取1只小鼠，测定外周血t淋巴细胞百分比、血清igg含量、血清铜锌超氧化物歧化酶和铜蓝蛋白活性、免疫器官指数及肝脏和脾脏铜含量。
The dynamic changes of cd4 and cds in the pbmc after challenged with prrsv were measured by flow cytometry . the cd4 * and cds * t lymphocytes in blood of porcine infected with prrsv were marked by anti - cd4 * and cds * t lymphocytes monoclonal antibodies , and then detected by flow cytometry 利用流式细胞仪检测猪感染prrsv以后不同时期cd4和cd8动态变化的研究，从猪心脏采血，分离外周血淋巴细胞，采用吉姆萨染色计数，单抗标记，然后进行流式分析。
Hi our study , dendritic cells ( dcs ) were derived from the cultivation of peripheral blood monocytes in vitro successfully . then to observe whether dcs transfected with carcinoembryonic antigen ( cea ) - vaccinia recombinant virus ( rv - cea ) can induces cytotoxic t lymphocyte - mediated cea - specific immunity in vitro 体外成功地完成了cd14 +单核细胞来源的树突状细胞( dc )的培养，并进一步研究人癌胚抗原重组痘苗病毒( rv - cea )转染dc后体外诱导的cea特异性细胞免疫。
Cd226 , also named platelet and t cell activation antigen 1 ( ptal ) , was discovered by burns in 1985 . pta1 mainly expressed on activated t cell , nk cell , megakaryocyte and platelet . previous study indicated that il - 2 , tnf - a and pma could upregulate the expression of pta1 on t lymphocytes and tgf - p down - regulate its expression Cd226又称为血小板和t细胞活化抗原1 ( plateletandtcellactivationantigen1 , pta1 ) ，最早在1985年由bums等发现，主要表达于活化t细胞、 nk细胞、巨核及血小板谱系，参与t细胞的活化与分化以及血小板的活化和聚集。
Campaired with the control groups , the absolute weight , grouth index and cell cycle of immune organs , the anae positive rates of t lymphocytes in peripheral blood , the erythrocyte c3brr and cic rosette rates were singnificantly changed in the zinc - deficient and zinc - toxic ducklings . histopathologically , lymphocytes of the immune organs were depleted , degenerated and necrotic in both zinc - deficient and zinc - toxic ducklings 缺锌和锌中毒组免疫器官的绝对重量、生长指数、细胞生长周期以及t淋巴细胞anae ~ +阳性率、红细胞c _ 3b受体花环、免疫复合物花环率与对照组比较差异显著( p 0 . 05 )或极显著( p 0 . 01 ) 。
In this dissertation , jurkat cells , hela cells and mouse spleen t lymphocytes were chosen as experimental materials to answer the question . with the aid of various techniques such as elisa , immuno - co - precipitation , indirect immunofluoresent co - localization , double - labeling immunoelectron microscopy and so on , the relationships of baf complex with nf1 / ctf and rna polymerase ii were careful observed and analyzed 本文以jurkat细胞、 hela细胞和小鼠脾t淋巴细胞为研究材料，通过酶联免疫吸附实验( elisa ) 、免疫共沉淀、免疫荧光共定位和免疫电镜双标记等实验，观察和分析了baf复合物与转录因子nf1 ctf和rna聚合酶在基因转录活动中的相互联系。
So , combined examination of mutation of hbv c gene , the concentration of cytokines and t lymphocyte subpopulations is very significant to real ise the relationship between hbv c gene mutation and the cellular immunity of the host , and also can offe r the basis to further announce the pathogenesis of chronic hepatitis b and individual diagnosis and treament 因此联合检测hbvdnac基回全序列、血清细胞因子水平及t细胞亚群，可以全面了解基因的变异情况，综合分析变异与细胞免疫功能的相关性，并为进一步揭示慢性乙肝的发病机理及个体化诊断和治疗提供依据。
