Key Roles of Renal Aquaporins in Water Balance and Water-Balance Disorders.

چکیده
The discovery of aquaporins by Agre and co-workers provided an answer to the long-standing biophysical question of how water can pass cell membranes. The identification and characterization of several aquaporins expressed in the kidney has allowed detailed insight, at the molecular level, into the fundamental physiology and pathophysiology of renal water metabolism.

Physiology 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 کاملLong-term regulation of aquaporins in the kidney.
The discovery of the aquaporin family of water channels has greatly improved our understanding of how water crosses epithelial cells, particularly in the kidney. The study of the mechanisms involved in the regulation of collecting duct water permeability, in particular, has advanced very rapidly since the identification and characterization of aquaporin-2 (AQP2) in 1993. One of the more surpris...
متن کاملThe Role of Aquaporins in the Kidney of Euryhaline Teleosts
WATER BALANCE IN TELEOST FISH IS MAINTAINED WITH CONTRIBUTIONS FROM THE MAJOR OSMOREGULATORY ORGANS: intestine, gills, and kidney. Overall water fluxes have been studied in all of these organs but not until recently has it become possible to approach the mechanisms of water transport at the molecular level. This mini-review addresses the role of the kidney in osmoregulation with special emphasi...
