Claudin 5 also known as CLDN5 is an integral component of tight junction strands within endothelial and epithelial cells. This protein possesses a molecular weight of approximately 23 kDa. It prominently expresses in the vascular endothelial cells of the blood-brain barrier and other blood-tissue barriers. Claudin 5 plays a mechanical role in forming selectively permeable paracellular barriers that regulate the movement of molecules and ions between cells. This function is essential in preserving the tissue-specific environment.
Claudin 5 serves as an important element in maintaining the integrity of the blood-brain barrier by creating a selective permeability. It operates as part of a larger tight junction complex interacting mainly with other claudin proteins and proteins such as occludin and ZO-1. These interactions ensure the structural and functional integrity of the cell junctions which helps stabilize the barrier properties against various physiological and pathological insults.
Claudin 5 is involved in important biological pathways such as the tight junction pathway and the barrier permeability regulation pathway. Through these pathways it interacts with proteins like occludin and various signaling molecules. This involvement allows tight regulation of barrier permeability ensuring selective transport and preventing the passage of harmful substances into sensitive areas like the central nervous system.
Claudin 5 plays a significant role in conditions like cerebral edema and Alzheimer's disease. Altered expression or dysfunction of Claudin 5 disrupts the blood-brain barrier contributing to these disorders. In Alzheimer's disease there is evidence of impaired tight junctions where Claudin 5 interacts with other claudins and related proteins like amyloid-beta affecting barrier integrity. Understanding these connections helps in developing therapeutic strategies targeting tight junction stability.
