    • Disclosed herein are immunoglobulin fusion proteins that have a first antibody region attached to an extender fusion region. The extender fusion region contains a therapeutic agent and a beta strand secondary structure. The extender fusion region may contain 7 or fewer consecutive amino acids based on or derived from an ultralong CDR3. Alternatively, the extender fusion region contains a rigid stalk protein structure, but does not contain an amino acid sequence based on or derived from an ultralong CDR3. The extender fusion region may also have one or more linkers or proteolytic cleavage sites. The immunoglobulin fusion proteins may have additional therapeutic agents and extender fusion regions. Also disclosed herein are pharmaceutical compositions of immunoglobulin fusion proteins and methods for using the immunoglobulin fusion proteins for the treatment or prevention of a disease or condition in a subject.
    • 本文公开了具有连接到增量融合区的第一抗体区的免疫球蛋白融合蛋白。 增量融合区域含有治疗剂和β链二级结构。 扩增融合区域可以含有7个或更少的基于或源自超长CDR3的连续氨基酸。 或者,扩增体融合区域包含刚性茎蛋白质结构,但不包含基于或衍生自超长CDR3的氨基酸序列。 扩展融合区也可以具有一个或多个接头或蛋白水解切割位点。 免疫球蛋白融合蛋白可以具有另外的治疗剂和增量融合区域。 本文还公开了免疫球蛋白融合蛋白的药物组合物和使用免疫球蛋白融合蛋白来治疗或预防受试者的疾病或病症的方法。
