Protocadherin gamma C3: a new player in regulating vascular barrier function.

Area of Science:

• Neuroscience
• Cell Biology
• Vascular Biology

Background:

• Endothelial cell barrier defects are implicated in various central nervous system disorders, including neurodegenerative diseases, stroke, and traumatic brain injury.
• Compromised endothelial sealing results in blood vessel leakage and vasogenic edema, a major cause of mortality following stroke and TBI.
• The blood-brain barrier, formed by brain microvascular endothelial cells and other neural cells, tightly regulates molecular traffic into the brain.

Purpose of the Study:

• To review recent evidence on molecules regulating brain microvascular endothelial cells.
• To highlight the role of protocadherin gamma C3 in vascular barrier function.

Main Methods:

• Literature review of recent findings on molecules involved in brain microvascular endothelial cell function.
• Analysis of studies investigating protocadherin gamma C3 expression and function.

Main Results:

• Several novel molecules regulating brain microvascular endothelial cells have been identified.
• Protocadherin gamma C3 is highly expressed in brain microvascular endothelial cells.
• Emerging evidence suggests protocadherin gamma C3 plays a key role in regulating vascular barrier function.

Conclusions:

• Protocadherin gamma C3 is a newly identified key regulator of vascular barrier function.
• Further research into protocadherin gamma C3 may offer new therapeutic targets for CNS disorders involving barrier dysfunction.
