1. 1. Studies of nucleotide receptors-induced calcium response in glomerular mesangial cells and afferent arterioles

   Författare :Antonio M. Gutiérrez; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Physiology and anatomy; mesangial cells; nucleotide receptors; purinoceptors; desensitization; afferent arterioles; ATP; UTP; adenosine; protein phosphatases; calcium; Fysiologi och anatomi; Physiology and pharmacology; Fysiologi och farmakologi; Physiology; fysiologi;

   Sammanfattning : It is known that intracellular calcium concentration ([Ca2+]i) changes in rat glomerular mesangial cells (GMC) and rabbit afferent arterioles (AA) in response to extracellular nucleotides. We studied the nucleotide-induced calcium response in cultured GMC and AA. 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. Calcium Responses in the Renal Afferent Arteriole to Angiotensin II and Norepinephrine Stimulation

   Författare :Mark Kornfeld; Klinisk neurofysiologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; norepinephrine; angiotensin II; smooth muscle cells; afferent arteriole; calcium; Kidney; renal hemodynamics; Physiology; Fysiologi;

   Sammanfattning : Studies were performed to investigate the influence of the vasoconstrictors angiotensin II (AII) and norepinephrine (NE) on calcium metabolism in smooth muscle cells of afferent arterioles. Fura-2 and image analysis techniques were used to evaluate calcium responses in the proximal and distal parts of afferent arterioles with attached glomeruli. LÄS MER

7. 5. 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
