The cribriform plate: A dynamic central nervous system-immune hub

Area of Science:

• Neuroscience
• Immunology
• Ophthalmology

Background:

• The cribriform plate (CP) contains olfactory nerve bundles and a rich perineural microenvironment (cpPME).
• The cpPME interfaces with cerebrospinal fluid, blood, bone marrow, and lymphatics.
• Immune dynamics within the cpPME are altered by neuroinflammatory conditions.

Purpose of the Study:

• To investigate the role of the cpPME in neuroinflammation.
• To explore the diagnostic potential of olfactory dysfunction in neurological disorders.
• To identify therapeutic opportunities targeting the cpPME.

Main Methods:

• Review of existing literature on CP anatomy and neuroinflammation.
• Analysis of immune cell interactions within the cpPME.
• Correlation of olfactory dysfunction with neurological disease markers.

Main Results:

• Neuroinflammation significantly alters the cpPME immune niche.
• Olfactory dysfunction is linked to CP neuroinflammation in various neurological diseases.
• The CP's proximity to the nasal mucosa offers a route for targeted therapies.

Conclusions:

• The cpPME is a critical immune site influenced by neuroinflammation.
• cpPME changes may serve as early diagnostic indicators for neurological disorders.
• Targeting the cpPME presents a promising strategy for treating neuroinflammatory diseases.
