Aquaporins and Neurodegenerative Diseases
Aquaporins (AQPs) are a family of widely distributed membrane-inserted water channel proteins providing a pathway for osmotically-driven water, glycerol, urea or ions transport through cell membranes and mechanisms to control particular aspects of homeostasis. Beside their physiological expression patterns in Central Nervous System (CNS), it is conceivable that AQPs are also abnormally expresse...
متن کاملPhysiology and pathophysiology of renal aquaporins.
The discovery of aquaporin-1 (AQP1) by Agre and associates answered the longstanding biophysical question of how water specifically crosses biological membranes. In the kidney at least 7 aquaporins are expressed at distinct sites. AQP1 is extremely abundant in the proximal tubule and descending thin limb and is essential for urinary concentration. AQP2 is exclusively expressed in the principal ...
متن کاملThe Relationship between Non-Renal Diseases and Renal Parenchymal Echogenicity in Children with Acute Abdominal Pain
Background Few results have shown that renal parenchymal echogenicity increases in pediatric patients with no concurrent renal diseases. This study aimed to investigate the relation between non-renal diseases and renal cortical echogenicity in children with acute abdominal pain. Materials and Methods This cross- sectional study was conducted among 100 children referred to Amirkola Children’s ...
متن کاملExpression of aquaporins in the renal connecting tubule.
The renal connecting tubule (CNT) is a distinct segment that occurs between the distal convoluted tubule (DCT) and the cortical collecting duct. On the basis of its characterization in rabbit it is widely believed that connecting tubule cells have a low permeability to water and do not respond to vasopressin. Here we utilize segment-specific markers and specific aquaporin antibodies to characte...
متن کاملDownregulation of renal aquaporins in response to unilateral ureteral obstruction.
The expression of aquaporin-2 (AQP2) is decreased in rats with bilateral ureteral obstruction (BUO) and unilateral ureteral obstruction (UUO). Therefore, the expression of additional renal aquaporins (AQP1-4) and phosphorylated AQP2 (p-AQP2), known to play a role in urinary concentration, was examined in a Wistar rat model with 24 h of UUO. In obstructed kidneys, immunoblotting revealed a signi...
