What are Tight Junctions and Their Role in Vascular Permeability?

Tight junctions are complexes of proteins that form a barrier between adjacent endothelial cells. They play a crucial role in regulating vascular permeability by controlling the passage of substances through the paracellular pathway. Key components include:
Disruption of tight junctions can lead to increased permeability and leakage of plasma components into surrounding tissues.
