Webb20 feb. 2008 · Leukocytes can transmigrate out of the vasculature by using either the paracellular or the transcellular route . The factors determining which pathway is preferred are unknown, but the pathway of choice might differ between organs, inflammatory stimuli and the type of leukocyte that is emigrating. WebbABSTRACT. The paracellular route is the dominant pathway for passive solute flow across both epithelial and endothelial barriers, and its permeability depends on the regulation of …
WebbThese cell-to-cell adhesion structures act as gatekeepers of the paracellular pathway (Figure 1b) by regulating the passive diffusion of molecules and ions into the brain [23,35,36]. The establishment of TJs at the BBB leads to a high electric resistance (>1000–3000 Ω cm 2 ) across the interface [ 37 , 38 ]. WebbWithin the paracellular pathway, a supramolecular structure, the tight junction transport is largely controlled by the temporospatial regulation of its major protein family called claudins. Besides the fact that the expression of claudins has been identified in different forms of human diseases like cancer, clearly defined mutations in the corresponding …
