Splenic sinus endothelial cells, which adhere through tight and adherens junctions, regulate the passage of blood cells through the splenic cord. The objective of this study was to assess the localization of tight junctional proteins, claudin-5 and ZO-1 in the sinus endothelial cells of rat spleen and to characterize spatial and functional relationships between tight and adherens junctions. Immunofluorescence microscopy of tissue cryosections demonstrated that claudin-5, ZO-1, and alpha-catenin were distinctly localized in the junctional regions of adjacent endothelial cells. Immunogold electron microscopy demonstrated claudin-5 localized in the tight-junctional fused membranes of adjacent endothelial cells. Immunogold labeling for ZO-1 was localized not only in the tight-junctional-fused membranes of endothelial cells but also in the junctional membrane. alpha-Catenin was intermittently localized along the juxtaposed junctional membranes of adjacent endothelial cells. Double-staining immunogold microscopy for claudin-5 and ZO-1, claudin-5 and VE-cadherin, ZO-1 and VE-cadherin, and ZO-1 and alpha-catenin demonstrated that ZO-1 was closely localized to VE-cadherin and alpha-catenin in their juxtaposed membranes of endothelial cells. Thus, ZO-1 might play an important role in regulating the cell-cell junctions of sinus endothelial cells for blood-cell passage through splenic cords.
