    • The present disclosure provides polypeptide heterodimers formed between two different single chain fusion polypeptides via natural heterodimerization of an immunoglobulin CH1 region and an immunoglobulin light chain constant region (CL). One chain of a heterodimer comprises a binding domain that specifically binds a target (e.g., a receptor). In addition, both chains of a heterodimer further comprise an Fc region portion. The present disclosure also provides nucleic acids, vectors, host cells and methods for making polypeptide heterodimers as well as methods for using such polypeptide heterodimers, such as in reducing T cell activation, inhibiting solid malignancy growth, and treating autoimmune or inflammatory conditions.
    • 本公开通过免疫球蛋白CH1区和免疫球蛋白轻链恒定区(CL)的天然异二聚化提供在两种不同单链融合多肽之间形成的多肽异二聚体。 异源二聚体的一条链包含特异性结合靶标(例如受体)的结合结构域。 此外,异二聚体的两条链还包含Fc区部分。 本公开还提供了用于制备多肽异源二聚体的核酸,载体,宿主细胞和方法以及使用这种多肽异源二聚体的方法,例如在减少T细胞活化,抑制实体恶性肿瘤生长和治疗自身免疫性或炎性病症。
