    • The invention provides methods for identifying protein modulators (e.g., antibody agonists) of eukaryotic cells. The methods typically involve expressing a combinatorial agent library (e.g., via lentiviral vectors) inside a eukaryotic cell type (e.g., a mammalian cell) and then directly selecting for agents (e.g., antibodies) that are agonist, of a target molecule (e.g.,. a signaling receptor) that modulates a phenotype of or elicits a cellular response in the cell. Some related methods involve co-culturing a cell expressing a combinatorial agent library and a second cell, and then selecting agents that modulate a phenotype of or elicit a cellular response in the second cell. Preferably, the agents are antibodies and are introduced into and expressed in the starting cells under conditions each individual cell expresses no more than 3 different members of the antibody library. In addition, the invention provides methods for identifying protein agonists that capable of reprograming or trans-differentiating a target cell. Also provided in the invention are specific agonist antibodies of signaling receptors or biomolecules that modulate a phenotype or effectuate a cellular response in a eukaryotic cell (e.g., agonist antibodies of EpoR, TpoR or G-CSFR). Further provided in the invention are methods for selecting from combinatorial antibody libraries bispecific antibodies that can regulate cell phenotypes.
    • 本发明提供鉴定真核细胞的蛋白质调节剂(例如抗体激动剂)的方法。 方法通常涉及在真核细胞类型(例如,哺乳动物细胞)内表达组合试剂文库(例如通过慢病毒载体),然后直接选择靶分子的激动剂(例如,抗体)(例如, 一种信号受体),其调节细胞中的表型或引起细胞反应。 一些相关方法涉及共培养表达组合试剂文库和第二细胞的细胞,然后选择调节第二细胞中表型或引起细胞应答的试剂。 优选地,所述试剂是抗体,并且在每个单个细胞表达不超过3个抗体文库的不同成员的条件下被引入并在起始细胞中表达。 此外,本发明提供了鉴定能够重新编程或反向分化靶细胞的蛋白质激动剂的方法。 本发明还提供了调节表型或在真核细胞(例如EpoR,TpoR或G-CSFR的激动剂抗体)中调节细胞应答的信号传导受体或生物分子的特异性激动剂抗体。 本发明还提供了从组合抗体文库中选择可以调节细胞表型的双特异性抗体的方法。

    • The present invention provides methods for identifying escape variants of a target polypeptide. The methods typically involve generating a library of variant polypeptides of the target polypeptide on a replicable display platform (e.g., phage display), identifying variant polypeptides which maintain the ability to bind to a known binding partner of the target polypeptide, and examining the identified variant polypeptides to identify escape variants whose binding to the binding partner is not antagonized by a library of known compounds which disrupt binding between the target polypeptide and the binding partner. The methods can further entail screening a library of candidate antagonist agents to identify a cognate antagonist agent which antagonizes binding between the escape variant and the binding partner. Additional escape variants can be identified by creating a library of further variant polypeptides of the identified escape variant, and subject the further variant polypeptides to the screening process. In each subsequent round of screening, the identified antagonist agent is combined with the library of known compounds employed in the previous round of screening. The invention also provides related methods for identifying novel antagonist agents of a target polypeptide. Further provided are vectors and kits for displaying a functional multimeric target protein on the surface of a phage.
