The choroid plexus (CP) is a highly vascularized structure located within the brain ventricles, consisting of epithelial cells that produce cerebrospinal fluid (CSF). Choroid plexus epithelial cells (CPECs) form the blood-CSF barrier and are increasingly recognized as important players in neurodegenerative diseases, including Alzheimer's disease (AD), Parkinson's disease (PD), and Multiple System Atrophy (MSA). These cells are affected by neurodegeneration through multiple mechanisms including senescence, inflammation, and impaired function.
The choroid plexus is found in all four ventricles:
Each CP consists of a core of fenestrated capillaries surrounded by a single layer of cuboidal epithelial cells connected by tight junctions[1].
CPECs form the blood-CSF barrier with several key features:
CPECs produce approximately 500-600 mL of CSF daily through:
| Property | Value |
|---|---|
| Cell type | Cuboidal epithelium |
| Key markers | AQP1, TTR, transthyretin, claudin-2 |
| Transporters | P-gp, BCRP, OAT1/3, OCTN2 |
| Secretory products | CSF, trophic factors, cytokines |
CPECs express numerous transporters mediating:
CP dysfunction in AD contributes to:
The choroid plexus shows morphological changes in AD including epithelial atrophy, basement membrane thickening, and reduced CSF production[3].
CP involvement in PD includes:
CP pathology in MSA includes:
CPECs undergo senescence in aging and neurodegeneration:
CP can accumulate disease-related proteins:
Neurodegeneration compromises CP barrier function:
CP-derived CSF markers:
Understanding CP function is critical for:
Single-cell analysis: CP cell heterogeneity
Organoid models: Human CP in a dish
Gene therapy: CP-targeted interventions
Biomarker development: CP-derived disease markers
