The transport of organic anions in the proximal tubule occurs primarily through the epithelial cells. This process involves movement across both the luminal and contraluminal membranes via specialized transport systems. Although some of the organic anions are taken up into the cell from the lumen, they can also be accumulated in tubule cells from the interstitial compartment by a variety of transporters. The relative affinities of anions for the different luminal and contraluminal transporters… CONTINUE READING
