One of the major challenges in identifying appropriate human transcytosis targets is that there is a species-specific transporter expression profile at the BBB, complicating translation of successful preclinical candidates into humans. In an effort to overcome this obstacle and identify proteins capable of binding human-relevant BBB ligands, we generated and screened a BBB-targeting library against human-induced pluripotent stem cell-derived brain microvascular endothelial-like cells (iPSC-derived BMEC-like cells).
