Choroid plexus and its relations with age-related diseases

Area of Science:

• Neuroscience
• Cell Biology
• Pathophysiology

Background:

• The choroid plexus epithelium forms the blood-cerebrospinal fluid barrier, essential for brain microenvironment homeostasis.
• This barrier regulates the passage of substances and immune cells into the brain.
• The choroid plexus's role in aging and neurodegenerative diseases is an emerging area of research.

Approach:

• This review synthesizes current knowledge on the choroid plexus epithelium's function.
• It examines the link between the choroid plexus and age-related neurological disorders.
• The review aims to identify potential therapeutic targets within the choroid plexus.

Key Points:

• Choroid plexus epithelial cells and their tight junctions create the blood-cerebrospinal fluid barrier.
• The choroid plexus secretes cerebrospinal fluid and other vital molecules, and acts as an immune gateway.
• Dysfunction of the choroid plexus is increasingly implicated in the development of age-related diseases.

Conclusions:

• The choroid plexus plays a significant role in maintaining brain health and is implicated in aging and neurodegeneration.
• Understanding the choroid plexus's pathophysiology may reveal novel therapeutic strategies for age-related neurological conditions.
