Barriers for solute and water transport in PD. The endothelial and mesothelial cell monolayers form leaky membranes. Intercellular junctions define the selective permeability properties and thus paracellular bulk flow of small and large solutes together with water. An in-depth understanding of these key elements of PD should provide promising therapeutic targets to improve PD efficacy, biocompatibility, and sustainability.
