Abstract
In rodents, the pH of the tubular fluid decreases as it flows along the inner medullary collecting duct (IMCD) towards the tip of the papilla (17,18, 30), indicating that this nephron segment is an important site of urinary acidification. This acidification primarily results from active proton secretion rather than bicarbonate reabsorption since it is accompanied with a luminal acidic disequilibrium pH (8, 16). However, there is little information concerning the molecular mechanism of apical proton secretion in this nephron segment.
