The choroid plexus as a sex hormone target: Functional implications.

Area of Science:

• Neuroscience
• Endocrinology
• Cerebrospinal Fluid Dynamics

Background:

• The choroid plexuses (CPs) are brain structures forming a critical blood-cerebrospinal fluid (CSF) interface.
• CPs play roles in CNS surveillance, development, neurogenesis, and circadian rhythms.
• Sex hormones (SH) are known modulators in neurodegenerative diseases and influence CP functions.

Purpose of the Study:

• To review the implications of sex-related specificities within the choroid plexuses.
• To examine how sex hormones affect CSF composition and brain homeostasis.

Main Methods:

• Literature review of existing studies on choroid plexus function and sex hormones.
• Analysis of research on sex hormone regulation of CP biological functions.
• Synthesis of evidence regarding SH impact on CSF composition.

Main Results:

• Evidence suggests estrogens and androgens regulate fundamental biological functions in the CPs.
• SH likely influence CSF composition, thereby affecting brain homeostasis.
• Sex-specific differences in CP function and regulation are increasingly recognized.

Conclusions:

• Sex hormones play a crucial role in modulating choroid plexus functions.
• Understanding CP sex-related specificities is vital for comprehending brain homeostasis.
• Further research into SH-CP interactions may reveal therapeutic targets for neurological disorders.
