Solute transport through the glomerular filtration barrier: the podocyte slit diaphragms' role in maintaining glomerular basement membrane integrity and podocyte-to-endothelial crosstalk.
A two-dimensional computational solute transport model is developed incorporating two cross-sectional GFB geometries that suggest the structural organization of the GFB, particularly the slit diaphragm, enables solute distribution and directional transport, and therefore provides insight into GFB maintenance and pathology.
