| 1. | Although scientists have made progress in diagnosing cell receptor diseases, they have not yet found a way to cure them .
虽然科学家在诊断细胞变体疾病上已经有了很大进展，但是他们还没有找出治愈的方法。 |
| 2. | But human and avian influenza viruses recognise different cell receptors
但是人类流感与禽流感病毒识别不同的细胞受体。 |
| 3. | The rearrangements of immunoglobulin heavy chain and t cell receptor genes in patients with acute nonlymphocytic leukemia
基因重排与急性非淋巴细胞白血病的相关性 |
| 4. | Objective : in most t eel ] malignancies , there are t cell receptors ( tcr ) expressed on the surface of the tumor cells
目的：大多数t细胞肿瘤表面有tcr独特型抗原，可作为肿瘤特异性抗原用于免疫治疗。 |
| 5. | In the new study , conducted by an international team of researchers , the viruses isolated from human patients in vietnam and thailand could recognise both human and avian cell receptors
在一个国际研究小组进行的新研究中发现，从越南和泰国患者中分离的病毒都能识别人类和禽细胞受体。 |
| 6. | Ricin b chain ( rtb ) can specifically recognize receptors on the cell membrane , which have a terminal galactose . rtb is responsible for the binding to the cell receptors and may facilitate the translocation of rta
B链具有凝集素活性，其本身几乎没有毒性，主要作用就是识别和结合细胞表面末端含有半乳糖基结构的受体，并协助a链进入细胞内。 |
| 7. | Effective activation of antigen - specific t cells not only requires the first signal transduction through t - cell receptor ( tcr ) binding with peptide - mhc complex on the antigen presenting cell ( apc ) , but also needs the second signal , termed costimulation . costimulation critical to the degree and consequence of t cell activation is provided by interaction between soluble factors or cell - surface molecules on the t cell and on the apc
而t细胞的活化除需要t细胞受体( tcr )与抗原呈递细胞( antigenpresentingcell , apc )表面的抗原肽- mhc复合物结合所形成的第一信号外，还需要t细胞和apc表面的其它膜分子结合所提供的共刺激信号(亦称第二信号或辅助刺激信号， costimulatorysignal )的参与。 |
| 8. | The hemaglutinin ( ha ) of aiv plays the key role in determing the pathogenicity , cell receptor binding property and host range of the virus . the homology of the ha sequences reported and registered in genbank of different strains of h _ ( 5 ) . h _ ( 9 ) subtype was respectively analyzed and compared with each other . the conservative domin of ha seqence of h _ ( 5 ) , h _ ( 9 ) subtype was selected for pcr amplification . two sets of specific primers were designed
本研究根据genbank中查出的禽流感病毒h _ 5亚型，禽流感病毒h _ 9亚型的ha片段基因组序列，利用dnasis软件分别对aiv的h _ 5 、 h _ 9亚型ha基因区域进行同源性比较，设计筛选出两对联合pcr反应的特异性引物，其中一对是h _ 9亚型通用引物，扩增出ha片段695bp ，另一对引物为h _ 5亚型的通用引物，扩增出的ha区域部分目的片段约为448bp 。 |
