  1. 1. Regulatory Functions of the Juxtaglomerular Apparatus

    Författare :Ruisheng Liu; Ole Skott; Uppsala universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; 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

  2. 2. Transforming growth factor-ß. Signal regulation in health and disease

    Författare :Urban Molander; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Nyckelord :TGF-b; BMP; Smad; signal transduction; LDL; skin tumour; mesangial;

    Sammanfattning : TGF-b superfamily members have been shown to play a pivotal role in multicellular organisms. Knowledge about signal transduction pathways is important in order to understand and cure diseases like cancer where TGF-b´s growth inhibitory signal often are disenabled via mutated or absent signalling components.

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

    Författare :Antonio M. Gutiérrez; Uppsala universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; 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

  4. 4. Molecular perspectives on glomerular cell physiology in chronic kidney disease

    Författare :Emelie Lassén; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Chronic kidney disease; IgA nephropathy; mesangial cell; podocyte; CKAP4;

    Sammanfattning : Glomerulonephritis is one of the most common causes of chronic kidney disease (CKD) in the world. Recent establishment of guidelines for classification of CKD in five stages has led to increased awareness of the risks of comorbidity and mortality, also in patients with early stages of disease, and the need to further advance our understanding of their pathogenic mechanisms.

  5. 5. Studies on the Role of Apoptosis in Kidney Diseases

    Författare :Linnéa Nilsson; Hjalmar Brismar; Anita Aperia; Lena Scott; Fredrik Palm; KTH; []

    Sammanfattning : Apoptosis is one of the most common types of cell death. Under physiological conditions, it plays an essential role in removal of damaged and potentially harmful cells. Excessive apoptosis has however been linked to a number of diseases including proteinuric kidney disease and DKD, and is believed to enhance the disease progression. LÄS MER
