Choroid plexus and CSF: an updated review

Area of Science:

• Neuroscience
• Physiology
• Biochemistry

Background:

• The choroid plexus (ChP) is a key brain structure.
• Its primary role in cerebrospinal fluid (CSF) dynamics is well-established.
• Recent studies suggest broader functions beyond CSF regulation.

Purpose of the Study:

• To review the literature on choroid plexus functions.
• To highlight both established and emerging roles of the ChP.
• To discuss the clinical relevance of ChP dysfunction.

Main Methods:

• Literature review of scientific articles.
• Synthesis of findings on ChP physiology and pathology.
• Analysis of the implications of ChP disruption.

Main Results:

• The ChP actively secretes, renews, and absorbs CSF.
• The ChP participates in regulating circadian rhythms.
• The ChP performs critical immune and chemical surveillance functions.
• ChP disruption is linked to neurodegenerative disorders.

Conclusions:

• The choroid plexus is a multifaceted brain component.
• Understanding its diverse functions is essential for neurological health.
• Further research into ChP roles may offer therapeutic targets for brain diseases.
