  1. 1. Local Purinergic Control of Arteriolar Reactivity in Pancreatic Islets and Renal Glomeruli

    Författare :Xiang Gao; Leif Jansson; Olle Hellberg; Uppsala universitet; []
    Nyckelord :afferent arteriole; islet arteriole; adenosine; A1 receptor; ATP; P2Y receptor; microperfusion; angiotensin II; type 2 diabetes; hypertension; oxidative stress; nitric oxide; tubuloglomerular feedback;

    Sammanfattning : Local control of regional blood flow is exerted mainly through the arterioles. An adequate minute-to-minute regulation of blood perfusion of the kidney and the pancreas is obtained by the modulation of arteriolar reactivity, which will influence the organ function. LÄS MER

  3. 2. Interaction between Adenosine and Angiotensin II in Renal Afferent Arterioles of Mice

    Författare :Enyin Lai; A. Erik G. Persson; Göran Bergström; Uppsala universitet; []
    Nyckelord :Physiology; adenosine; angiotensin II; afferent arteriole; calcium; nitric oxide; microperfusion; tubuloglomerular feedback; Fysiologi;

    Sammanfattning : Renal arterioles represent the most important effecter site in the control of renal perfusion and filtration. Adenosine (Ado), angiotensin II (Ang II) and nitric oxide (NO) interact in modulating arteriolar tone. The present work investigates the mechanism of this interaction. LÄS MER

  4. 3. Regulatory Functions of the Juxtaglomerular Apparatus

    Författare :Ruisheng Liu; Ole Skott; Uppsala universitet; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER
