The localisation of alkaline-, adenosine tri-, glucose-6- and acid phosphatase was studied in the juxtaglomerular complexes of rat, mouse and human kidneys. An alkaline-and adenosine triphosphatase active region was observed between the macula densa, Goormaghtigh cell group and in the interstitium of the latter. The adenosine triphosphatase activity extended into the lateral cell membranes of the macular cells and in properly incubated sections it did not appear among other distal tubular cells. The granular juxtaglomerular cells were ATP-ase negative. The cells of the human macula densa and the granular juxtaglomerular cells of the rat and mouse showed acid phosphatase activity. The glucose-6-phosphatase reaction, accomplished at acid and alkaline pH, was negative in the JG complex of all three species. The possible role of these enzymes in the function of the JG complex also has been discussed. [ABSTRACT FROM AUTHOR] |
