摘要： The invention provides a method for obtaining a broadly neutralizing antibody (bNab), including screening memory B cell cultures from a donor PBMC sample for neutralization activity against a plurality of HIV-1 species, cloning a memory B cell that exhibits broad neutralization activity; and rescuing a monoclonal antibody from that memory B cell culture. The resultant monoclonal antibodies may be characterized by their ability to selectively bind epitopes from the Env proteins in native or monomeric form, as well as to inhibit infection of HIV-1 species from a plurality of clades. Compositions containing human monoclonal anti-HIV antibodies used for prophylaxis, diagnosis and treatment of HIV infection are provided. Methods for generating such antibodies by immunization using epitopes from conserved regions within the variable loops of gp120 are provided. Immunogens for generating anti-HIV1 bNAbs are also provided. Furthermore, methods for vaccination using suitable epitopes are provided.
摘要翻译： 本发明提供了获得广泛中和抗体（bNab）的方法，包括筛选来自供体PBMC样品的记忆B细胞培养物，以对多种HIV-1物质进行中和活性，克隆显示广泛中和活性的记忆B细胞; 并从该记忆B细胞培养物中拯救单克隆抗体。 所得到的单克隆抗体的特征在于它们以天然或单体形式选择性地结合来自Env蛋白的表位的能力，以及抑制HIV-1物种从多个进化枝的感染的能力。 提供了含有用于预防，诊断和治疗HIV感染的人单克隆抗HIV抗体的组合物。 提供了通过使用来自gp120的可变环内的保守区域的表位的免疫来产生这种抗体的方法。 还提供了产生抗艾滋病毒1型免疫球蛋白的免疫原。 此外，提供了使用合适表位的疫苗接种方法。

摘要： The invention provides a method for obtaining a broadly neutralizing antibody (bNab), wherein said antibody is PGG14 having a heavy chain comprising the amino acid sequence of SEQ ID NO: 20 and a light chain comprising the amino acid sequence of SEQ ID NO: 22. Said method includes screening memory B cell cultures from a donor PBMC sample for neutralization activity against a plurality of HIV-1 species, cloning a memory B cell that exhibits broad neutralization activity; and rescuing a monoclonal antibody from that memory B cell culture. The resultant monoclonal antibody of the invention is characterized by its ability to selectively bind epitopes from the Env proteins in native or monomeric form, as well as to inhibit infection of HIV-1 species from a plurality of clades. Compositions containing said human monoclonal anti-HIV antibody of the invention, which are used for prophylaxis, diagnosis and treatment of HIV infection, are provided. Methods for generating such antibody by immunization using epitopes from conserved regions within the variable loops of gp120 are provided. Immunogens for generating anti-HIVl bNAbs are also provided. Furthermore, methods for vaccination using suitable epitopes are provided.
