This strategy combines LDLR upregulation in brain endothelial cells with engineered LRP1-targeting antibodies containing pH-responsive endosomal escape mechanisms for enhanced CNS delivery. The approach begins with targeted pharmacological or gene therapy-mediated upregulation of LDLR expression in brain capillary endothelium, which primes the cholesterol transport machinery and creates a metabolically active endothelial environment that enhances LRP1 receptor cycling and transcytotic capacity.
## Mechanistic Overview
FcRn Transport Bypass Strategy starts from the claim that modulating LDLR within the disease context of neuropharmacology can redirect a disease-relevant process. The original description reads: "# FcRn Transport Bypass Strategy: A Novel Approach to CNS Antibody Delivery
## Introduction
The development of therapeutic antibodies for neurodegenerative diseases has been constrained by the blood-brain barrier (BBB), a specialized endothelial structure that restricts the par
