Along with beta-intercalated cells, they play a critical role in the body’s acid-base balance. Renal alpha-intercalated cells contain an abundance of proton pumps and enzymes like carbonic anhydrase, which aid in the transport of hydrogen ions for secretion in the urine. The bicarbonate/chloride transporters on their apical membrane meanwhile take up bicarbonate ions from the urine and supply them back into the blood. Through this mechanism, these cells contribute significantly to the neutrality of blood pH, and dysfunction of renal alpha-intercalated cells often leads to distal renal tubular acidosis, a condition resulting in acidic blood and alkaline urine.
