Symport apical
WebSLC26A4 (also named Pendrin or PDS) and SLC5A8 genes codify for the thyroid follicular cell apical iodide transporters [57,58]. In one study, which included 64 primary thyroid … Because NCC is located at the apical membrane of the distal convoluted tubule of the nephron, it faces the lumen of the tubule and is in contact with the tubular fluid. Using the sodium gradient across the apical membrane of the cells in distal convoluted tubule, the sodium-chloride symporter transports Na and Cl from the tubular fluid into these cells. Afterward, the Na is pumped out of the cell and into the bloodstream by the Na -K ATPase located at the basal memb…
