The blood-brain interface: a culture change.

Area of Science:

• Neuroscience
• Immunology
• Cell Biology

Background:

• The blood-brain interface (BBI) is crucial for brain function and is increasingly recognized in psychiatric and neurological disorders.
• Significant advancements in the last decade have reshaped our understanding of BBI's role in health and disease.

Purpose of the Study:

• To review key discoveries in blood-brain interface (BBI) research over the past ten years.
• To highlight emerging tools and their potential for studying the human BBI.
• To emphasize the BBI's central role in immunopsychiatric syndromes and brain disease management.

Main Methods:

• Review of recent scientific literature on solute and cell trafficking across the BBI.
• Examination of endothelial cell and pericyte biology in the context of the BBI.
• Discussion of extracellular matrix components influencing the BBI.
• Exploration of novel tools for BBI research and clinical application.

Main Results:

• The BBI plays a critical role in conditions such as sickness behavior, delirium, and psychosis associated with specific antibodies.
• Understanding of solute and cell transport across the BBI has significantly improved.
• New tools are enabling more detailed investigation of the human BBI.
• The BBI is a key target for diagnosing and treating various brain diseases.

Conclusions:

• The past decade has yielded exciting breakthroughs in blood-brain interface (BBI) research.
• Continued exploration of the BBI promises further insights into human behavior and brain disorders.
• The BBI is integral to understanding and managing a spectrum of neurological and psychiatric conditions.
