白蛋白和免疫球蛋白具有相当长的血清半衰期,这是因为依赖于pH的FcRN介导的细胞循环将这两种配体从细胞内降解中拯救出来。此外,增加免疫球蛋白和白蛋白类药物的半衰期有可能提高它们的疗效,但非常需要可靠的方法来筛选相对FcRN依赖的循环能力。在这里,我们报告了一种新的基于人内皮细胞的循环试验(HERA),可以用于此类临床前筛查。在HERA中,从降解中拯救依赖于FcRN,并且在人类FcRN转基因小鼠中,工程配体以与其半衰期相关的方式被回收。因此,HERA是一种新的细胞检测方法,可用于预测FcRN结合蛋白如何从细胞内降解中解救出来。半衰期延长的基于免疫球蛋白和白蛋白的治疗药物的发展需要更有效的筛查程序。在这里,作者报告了一种基于人类内皮细胞的循环试验,能够在动物试验之前筛选免疫球蛋白和白蛋白变体,而不需要化学标记。
Albumin and IgG have remarkably long serum half-lives due to pH-dependent FcRn-mediated cellular recycling that rescues both ligands from intracellular degradation. Furthermore, increase in half-lives of IgG and albumin-based therapeutics has the potential to improve their efficacies, but there is a great need for robust methods for screening of relative FcRn-dependent recycling ability. Here, we report on a novel human endothelial cell-based recycling assay (HERA) that can be used for such pre-clinical screening. In HERA, rescue from degradation depends on FcRn, and engineered ligands are recycled in a manner that correlates with their half-lives in human FcRn transgenic mice. Thus, HERA is a novel cellular assay that can be used to predict how FcRn-binding proteins are rescued from intracellular degradation. The development of IgG and albumin-based therapeutics with increased half-lives needs more efficient screening procedures. Here the authors report a human endothelial cell-based recycling assay enabling screening of IgG and albumin variants without chemical labelling and prior to animal testing.
