Thus, cell-to-cell communication between macula densa cells and mesangial cells, which express P2Y(2) receptors, involves the release of ATP from macula densa cells via maxi anion channels at the basolateral membrane. This mechanism may represent a new paradigm in cell-to-cell …

They are the critical link between renal salt and water excretion and glomerular hemodynamics, thus playing a key role in regulation of body fluid volume. Since identification of these cells in the early 1900s Macula densa cells detect changes in luminal sodium chloride concentration through a complex series of ion transport-related intracellular events. NaCl entry via a Na:K:2Cl cotransporter and Cl exit through a basolateral channel lead to cell depolarization and increases in cytosolic calcium. Macula densa cell function.

Macula densa cells are located in the distal convoluted tubule, and stimulate juxtaglomerular cells to release renin when they detect a drop in sodium concentration in tubular fluid. Together, juxtaglomerular cells, extraglomerular mesangial cells and macula densa cells comprise the juxtaglomerular apparatus. In appropriately stained tissue

cell type of Macula densa er en specialiseret del af den distale tubulus, der sammen med de juxtaglomerulære celler danner det juxtaglomerulære apparat, som producerer renin og har betydning for blodtryksregulering.

We studied the fine structure of human MD cells focusing on their apical and basal ends and correlating structure and function.
