    Abstract: The present invention relates to human antibodies that binds specifically to the extracellular water-soluble domain of DLK1 and fragments which include antigen-binding sites thereof; a polynucleotide which encodes for the human antibodies or fragments thereof; a recombinant vector containing the polynucleotide; transformants transformed with the recombinant vector; method for manufacturing the human antibodies or fragments thereof; a pharmaceutical composition for preventing or treating disease which includes the human antibodies or fragment thereof; and diagnostic kits. Human antibodies and fragments which include antigen-binding sites that bind specifically to the extracellular water-soluble domain of DLK1 of the present invention show anti-tumor activity. By significantly raising the binding capacity of the DLK1 extracellular water-soluble domain to the Activin receptor type II B (ACVR2B), utility is demonstrated for prevention and treatment of diseases associated with ACVR2B signal transduction including related metabolic disorders, immune disease, liver diseases, and cancer.

    Abstract translation: 本发明涉及与DLK1的细胞外水溶性结构域特异性结合的人抗体和包括其抗原结合位点的片段; 编码人抗体或其片段的多核苷酸; 含有多核苷酸的重组载体; 用重组载体转化的转化体; 制造人抗体或其片段的方法; 用于预防或治疗疾病的药物组合物,其包括人抗体或其片段; 和诊断试剂盒。 包括与本发明的DLK1的细胞外水溶性结构域特异性结合的抗原结合位点的人抗体和片段显示抗肿瘤活性。 通过显着提高DLK1细胞外水溶性结构域与激活素受体IIB(ACVR2B)的结合能力,证明了预防和治疗与ACVR2B信号转导相关的疾病的效用,包括相关代谢紊乱,免疫疾病,肝脏疾病, 和癌症。
