A) Schematic of the pathways taken by molecules across a cellular barrier. Material is moved either between the cells via the paracellular pathway or across the cells via transcytosis, pores or membrane transporters. B) Schematic of the endothelial phenotypes and their content of structures that were involved in transport across endothelium; TEC, transendothelial channels; VVO, vesiculo-vacuolar organelles.
