**Molecular Mechanism and Rationale**
The low-density lipoprotein receptor (LDLR) represents a promising gateway for therapeutic delivery across the blood-brain barrier through receptor-mediated transcytosis. The LDLR belongs to the LDLR gene family and is abundantly expressed on brain capillary endothelial cells, where it normally facilitates cholesterol homeostasis through apolipoprotein B (ApoB) and apolipoprotein E (ApoE) recognition. The receptor's extracellular domain contains seven ligan
## 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)
