Abstract | Background: Tight junctions (TJs) are membrane specializations characteristic of barrier-forming membranes, which function to seal the aqueous pathway between endothelial cells or epithelial cells and, thereby, obstruct intercellular solute and cellular movement. However, previous work from our laboratory found that claudin-5 (CLN-5), a TJ protein prominent at the blood-brain barrier (BBB), was also detected, ectopically, on leukocytes (CLN-5 Methods: To begin clarifying the significance of CLN-5 Results: Flow cytometric analysis revealed CLN-5 Conclusion: Several leukocyte subtypes variably acquire CLN-5 in blood before they enter the CNS, an event that may represent a novel mechanism to guide leukocytes to sites for paracellular diapedesis across the BBB. |
