Mechanistic description

Engineer antibody Fc regions with pH-dependent binding profiles optimized specifically for brain endothelial FcRn interactions. These variants would have reduced systemic FcRn binding but enhanced BBB-specific transport.

Debate provenance: derived from debate sess_SDA-2026-04-12-gap-debate-20260410-112908-13c403ee on question: What is the actual quantitative contribution of FcRn-mediated transcytosis to BBB antibody transport in humans?. Consensus signal: domain_expert, medicinal_chemist, skeptic, synthesizer, theorist discussed the mechanism terms Alternative, BBB, Engineering, FCGRT, Specificity, transport. Novelty signal: skeptic-discussed-counterarguments.
