  2. 1. Macula Densa Derived Nitric Oxide and Kidney Function

    Author : Anna Ollerstam; Pontus Persson; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cell biology; Nitric oxide; rats; kidney; macula densa cells; tubuloglomerular feedback; renin; angiotensin II; blood pressure; hypertension; renal blood flow; neuronal nirtic oxide synthase; Cellbiologi; Cell biology; Cellbiologi; Physiology; fysiologi;

    Abstract : The kidney is the major organ regulating the extracellular fluid volume and thereby the arterial blood pressure. The neuronal isoform of nitric oxide synthase (nNOS) in the kidney is predominantly located in the macula densa cells. READ MORE

  4. 2. Regulatory Functions of the Juxtaglomerular Apparatus

    Author : Ruisheng Liu; Ole Skott; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cell biology; mesangial; desensitization; nitric oxide; calcium; P2Y receptor; macula densa; NaCl; luminal. microperfusion; angiotensin; Cellbiologi; Cell biology; Cellbiologi; Medicine; medicin;

    Abstract : The tubuloglomerular feedback mechanism is an important regulator in the juxtaglomerular apparatus and it detects flow dependent alterations in luminal NaCl concentration ([NaCl]) at the macula densa (MD) cell site via a Na+-K+-2Cl cotransporter. Signals are sent by the MD to adjust the afferent arteriole tone and altering release of renin. READ MORE

  5. 3. Functional Aspects of the Juxtaglomerular Apparatus : Control of Glomerular Filtration and Renin Release

    Author : Johan Sällström; Erik Persson; Peter Hansell; Jürgen Schnermann; Uppsala universitet; []
    Keywords : MEDICINE; MEDICIN; Medical Cell Biology; Medicinsk cellbiologi;

    Abstract : The juxtaglomerular apparatus (JGA) is a control unit of the kidney, that regulates glomerular filtration rate (GFR) and renin release, and hence extracellular volume and blood pressure. The tubuloglomerular feedback (TGF) mechanism is a negative feedback loop that regulates GFR. READ MORE
