recombinant retroviral production and infection of b cells

在真核细胞基因的转基因表达是一个功能强大的反向遗传学方法，在其中一个感兴趣的基因是异源表达系统的控制下表达，以方便所产生的表型分析。这种方法可以用来在生物体中发现一个不正常的基因表达，表达了一个基因产物的突变形式，或过度表达的基因产物的显性负形式。它是造血系统的研究，转录调控是一个主要控制机制，在发展和分化的B 细胞在2-4审查，特别有用。 小鼠遗传学是研究人类基因和疾病的有力工具。一个小鼠和人类基因组的比较分析，揭示了共线性的保护，在超过90％的基因组5此外，在小鼠模型所使用的技术是适用于人类基因的研究，例如， 基因 干扰和等位基因更换6。然而，转基因小鼠的建立需要一个很大的金融和技术性质资源。有几个项目已经开始编译库（KOMP，EUCOMM，NorCOMM）敲除小鼠品系或突变引起的菌株（理研），这需要大规模的努力和合作 7的。因此，这是可取的，首先研究的一个发展的小鼠模型前，在原代细胞的细胞培养模型所需的基因表型。 逆转录病毒的DNA整合到宿主DNA中，最好内或附近转录单位或CpG岛，稳定和遗传利益打包基因的表达，同时避免转录沉默 8 9。然后下一个高效率的逆转录病毒启动子控制转录的基因，在转录和蛋白质的生产效率高。因此，逆转录病毒表达可用于难转染的细胞，细胞在有丝分裂过程中的一个活跃的状态。由于该病毒的结构基因内包装细胞系中，用于克隆感兴趣的基因的表达载体含有病毒没有结构基因，这既消除了病毒的回复的可能性，并增加了安全与病毒上清工作如没有传染性的病毒粒子产生的 10 。 在这里，我们提出了一个脾B细胞重组逆转录病毒的生产和后续感染的协议。隔离后，刺激培养的脾细胞与钍派生淋巴因子和抗CD40，诱导B细胞的增殖和分化 11爆裂。此协议是为年底发生在B细胞发育和分化，B细胞是从以下初始造血事件，但在抗原刺激诱导浆细胞分化的脾孤立的事件研究的理想。
