**Molecular Mechanism and Rationale**
Low-density lipoprotein receptor-related protein 1 (LRP1) represents a critical transcytotic gateway at the blood-brain barrier (BBB), offering unprecedented opportunities for therapeutic antibody delivery to the central nervous system. LRP1 is a large transmembrane receptor (600 kDa) composed of an α-chain (515 kDa) and a β-chain (85 kDa) linked by disulfide bonds. The receptor contains four ligand-binding domains in its extracellular region, each harborin
## Mechanistic Overview
pH-Sensitive Bispecific Antibody Targeting Transferrin Receptor for CNS Delivery starts from the claim that modulating TFRC (TfR1); endosomal acidification pathway within the disease context of neurodegeneration can redirect a disease-relevant process. The original description reads: "## **Molecular Mechanism and Rationale** The pH-sensitive bispecific antibody platform leverages the natural endocytic trafficking pathway of the transferrin receptor (TfR1, encoded by TFRC)
