Species-Optimized Preclinical Models
🧪 Overview
Create transgenic mouse models expressing human FcRn at physiologically relevant BBB levels to resolve the species translation gap. Current preclinical models may over- or under-estimate human FcRn 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 BBB, FCGRT, Models, Preclinical, Species-Optimized, transport. Novelty signal: skeptic-discussed-counterarguments.
