Blood Brain Barrier Transport Cells is an important component in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.

Overview

This page provides comprehensive information about the cell type. See the content below for detailed information. [@zlokovic2011]

The blood-brain barrier (BBB) contains specialized transport systems that regulate the passage of nutrients, drugs, and waste products between the blood and brain. Dysfunction of these transporters is implicated in neurodegenerative diseases. [@patching2017]

Transport Systems

Nutrient Transporters

Efflux Transporters

ABC Transporters (ATP-binding cassette):

• P-glycoprotein (P-gp/MDR1) - Major efflux
• BCRP - Breast cancer resistance protein
• MRP1-5 - Multidrug resistance proteins

Receptor-Mediated Transport

• Transferrin receptor (TfR1) - Iron uptake
• Insulin receptor - Insulin transport
• Leptin receptor - Leptin transport
• ApoE receptors - Lipid transport

Neurodegeneration

Alzheimer's Disease

Transport Changes:

• GLUT1↓ - Reduced glucose uptake
• P-gp dysfunction - Aβ clearance impaired
• LRP1↓ - Aβ transport reduced
• RAGE↑ - Aβ influx enhanced

Parkinson's Disease

• P-gp - Reduced function in SN
• BBB penetration - Drug delivery challenge
• Efflux alterations - Toxin accumulation
• Dopamine transporters - Complex interactions

ALS

• BBB breakdown - Early event
• SOD1 effects - Endothelial dysfunction
• Drug delivery - Major challenge
• Immune cell entry - Enhanced

Therapeutic Implications

Enhancing Drug Delivery

Restoring Transport Function

• GLUT1 upregulation - SGLT2 inhibitors
• P-gp modulators - Second generation
• Receptor targeting - Trojan horse antibodies

Biomarkers

Transport Function

• CSF/serum ratios - Drug penetration
• Imaging - PET ligands for P-gp
• Expression studies - Postmortem tissue
• In vitro models - iPSC-endothelial

Background
