Macula densa cells serve an important function in coupling renal hemodynamics with tubular reabsorption in that they monitor the sodium chloride concentration of the tubular fluid and via paracrine signaling molecules like prostaglandin E2 (PGE2), ATP, adenosine, and NO provide a feedback mechanism that adapts glomerular filtration to tubular reabsorption (tubuloglomerular The macula densa. As the distal proximal tubule rises from the renal medulla, it makes close contact with the glomerulus. The cells on the side of the tubule facing the glomerulus have a distinct appearance and constitute the macular densa (Figure 1). These cells sense the NaCl content of the tubule and make changes to GFR appropriately. 2003-04-01 2021-02-05 A new view of macula densa cell microanatomy.

Macula densa celler

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. Celler i macula densa reagerer på ændringer i natriumchloridniveauerne i den distale tubule af nefronen via tubuloglomerular feedback (TGF) -sløjfen. Macula densas påvisning af forhøjet natriumchlorid, som fører til en stigning i GFR, er baseret på begrebet purinerg signalering . 1) Macula densa celler: Specialiserede celler i tubulus væggen, der vender mod de andre celler i det juxtaglomerulære apparat. 2) Granulaceller: Eller juxtaglomerulære celler. Modificerede glatte muskelceller der overvejende findes i den afferente arteriole. Ved stimulation kan disse celler secernere enzymet renin.

Whole-cell patch-clamp experiments. This video is about "Macula densa". This video series is something special. We're fully delving into all things everything and all things about Cells of the 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.

The cells of the macula densa are sensitive to the concentration of sodium chloride in the distal convoluted tubule. Macula densa cells serve an important function in coupling renal hemodynamics with tubular reabsorption in that they monitor the sodium chloride concentration of the tubular fluid and via paracrine signaling molecules like prostaglandin E2 (PGE2), ATP, adenosine, and NO provide a feedback mechanism that adapts glomerular filtration to tubular reabsorption (tubuloglomerular feedback [TGF]).
