In contrast , " only one infectious particle is sufficient to trigger a b cell because that ' s the way na ture designed it , " hollis notes . " it ' s a beautifully sensitive system . 与之形成对比的是， “一个传染原粒子就足以引发b细胞，因为自然界本身就是这样设计的， ”霍利斯说： “这个系统异常灵敏，令人叹为观止。 ”
In consideration of this the eleventh international conference of diabetes in 1997 stressed that if drugs like glibenclamide no longer have any effect their use should be stopped to let b cells have a rest 故九七年“第十一届国际糖尿病会议”上特别强调“磺脲类药品临床一旦失效，则须停用，令b细胞得一休息” 。
Has made a regain of coenzyme i inside the b cells , thereby create a necessary material conditions for activating the b cells activation by impelling b cells to again fatten , proliferate and regenerate 从而使b细胞得到了重新肥大增殖再生为启动其生理活性创造了必要的物质条件。这就是内因是决定因素的道理。
Why does yi heng has such a predominant effect of pushing blood sugar down ? from the above mentioned changes occurring to islet cytomorphology of the four groups of experimental rat it can be seen that the main composition of yi heng , jiangtangsu 尤其从四组大鼠胰岛组织细胞形态学改变中可见，胰衡中主要有效成份降糖素- deona确与胰岛b细胞有一种特殊亲和力。
However , understanding the regulatory processes of the humoral response to transplantation and the mechanisms underlying therapeutic agents and protocols for preventing and treating sensitization requires a way to study hla - specific b cells 但是，要了解针对移植的体液反应的调节过程、潜在治疗因子的机制、预防和治疗致敏（患者）方案，需要研究hla特异性b细胞。
Elegant microfluidics , also developed at lincoln , direct the sample and nutrient media through the channel , where a charge - coupled device ( ccd ) like those found in camcorders detects even a single b cell firing 先进的微流体芯片? ?同样由林肯实验室研制? ?指引样本和营养介质通过通道，通道中即使只有一个b细胞发光，与便携摄像机里的装置类似的电荷耦合器也会探测到。
Naa can not only defend the invasion of various microorganism , but maintain the stability of internal envioment , lead to self tolerance , regulate immunity and prevent tumor progression 从不同角度对naa的研究显示： naa的产生可能与自身反应性b细胞克隆阳性选择过程有关； naa对外可以抵御外来微生物的入侵；对内可以维持机体内环境的稳定，引起自身耐受，调节免疫和抗肿瘤。
Ganoderma sp . 24 , ganoderma australe ( fr . ) pat . 60 and ganoderma sanmingense zhao et zhang 63 show high activities of inhibiting kb or hl - 60 cells , and ganoderma sp . 24 and ganoderma sanmingense zhao et zhang 63 have a - glucosidase inhibitory activities in vitro 树舌24和南方树舌60的氯仿相对kb细胞和hl - 60细胞摘要都有抑制活性：而三明树舌63 “的乙酸乙酯相对b细胞有一定的抑制活性。
Result 1 , human antisense cd40 rna eukaryotic expression vector was constructed successfully . 2 , in the presence of cd40 / pcdna3 , cd40 expression was significantly decreased , cell proliferation and antibodies generation were significantly restrained , compared to that of the controls ( p < 0 . 01 ) 2 、与转染pcdna3空载体组或未转染质粒组相比较，转染cd40 pcdna3的健康人及sle患者b细胞系cd40的表达均明显减少，增殖能力明显下降， ig的分泌受到明显抑制。
