摘要

当可变的、多样的和连接的外显子重组并形成多样的b细胞受体时产生免疫。免疫球蛋白基因的体细胞重排称为VDJ重组。该活性由RAG1和RAG2蛋白控制,与信号序列结合并开始切割。双链断裂由活性氧、核酶和ATM产生。RAG蛋白诱导裂解活性。通过CSR交换段。裂解活动后,片段发生洗牌。TDT引起核苷酸碱基的增加或减少。AID和RAG开始了对恒定区外显子进行洗牌的CSR过程。NHEJ的核心具有催化亚基(DNA-Pkcs)。Ku-DNA复合物对NHEJ的核酸酶、聚合酶和连接酶的附着具有重要作用。RAG2与组蛋白H3K4Me3启动重组活性。HMG1和HMG2促进突触和切割。DExD\H的RNA解旋酶诱导构象变化。ZnA具有连接酶活性。Ku参与附着NHEJ因子DExD/H box,诱导构象变化。NHEJ机制有XRCC4, XLF和PAXX,它们连接DNA末端。蛋白激酶B和磷酸肌苷-3激酶参与RNA表达。TOR69-3A2是中和西部马脑炎病毒的抗体。AMMO1是预防爱泼斯坦棒状病毒感染的抗gH/gL单克隆抗体。抗体也用于埃博拉病毒和肝炎。WT和HVR1 gpE1/gpE2产生针对任何类型的HCV交叉基因型中和表位的抗体。GPE118、GPE325、GPE534分别靶向不同的埃博拉病毒表位。

Recombinant Antibodies and Vaccines for Viruses
Immunity produced when variable, diverse, and joining exons recombine and form diverse B-cell receptors. Somatic rearrangement of immunoglobulin genes termed VDJ recombination. This activity is controlled by RAG1 and RAG2 proteins, binds to the signal sequences and start cleavage. Double stranded breaks are produced by ROS, Nuclear enzymes and ATM. RAG protein induces cleavage activity. Segments exchange by CSR. After cleavage activity shuffling of segments occurs. TDT cause gain or loss of nucleotide bases. AID and RAG begins the process of CSR that shuffle exons of constant region. The core of NHEJ have catalytic subunit (DNA-Pkcs). Ku-DNA complex is important for the attachment of nuclease, polymerase and ligase of NHEJ. RAG2 with histone H3K4Me3 start recombination activity. HMG1 and HMG2 promote synapsis and cleavage. RNA Helicase of the DExD\H induces conformational changes. ZnA have ligase activity. Ku involved in the attachment of NHEJ factor DExD/H box who induce conformational changes. NHEJ machinery has XRCC4, XLF, and PAXX who ligate DNA ends. Protein kinase B and phosphoinositide-3 kinase involved in RNA expression. TOR69-3A2 is antibodies that neutralized Western equine encephalitis virus. AMMO1 is the anti gH/gL monoclonal antibody prevent to the Epstein bar virus infection. Antibodies also used for Ebola virus and Hepatitis. WT and HVR1 gpE1/gpE2 produce antibodies which target any type of cross-genotype neutralizing epitopes for HCV. GPE118, GPE325, GPE534 are targeted to different epitopes for Ebola virus.
