Nephrology

Nephrology is the study of the kidney, including both normal kidney function and kidney diseases. The Renin-Angiotensin-Aldosterone System (RAAS), also known as the Renin-Angiotensin System (RAS), is a multi-hormonal system that coordinates a variety of physiological processes for proper regulation of blood volume and pressure. RAAS regulates sodium and water absorption in the kidney, thus directly impacting systemic blood pressure.

Typically, RAAS is activated when a drop in blood pressure (reduced blood volume) occurs to increase water and electrolyte reabsorption in the kidneys, which compensates for the drop in blood volume and increases blood pressure.

When renin is released into the blood, it acts upon a circulating substrate, angiotensinogen, that undergoes proteolytic cleavage to form the decapeptide angiotensin I. Vascular endothelium, particularly in the lungs, has an enzyme, angiotensin converting enzyme (ACE), that cleaves off two amino acids to form the octapeptide, angiotensin II (AII), although many other tissues in the body (heart, brain, vascular) also can form AII.

The one-dimensional standard of kidney disease detection is incompatible with the complexity of renal pathology. The diagnosis of kidney disease has largely focused on glomerular filtration, while assessment of kidney tubular health has notably been absent. Kidney tubular cells undergo a cascade of cellular responses that result in the production and accumulation of low-molecular-weight proteins in the urine and systemic circulation. Recent advancements in molecular analysis and proteomics have allowed the identification and quantification of these proteins as biomarkers for studying kidney diseases. 

IBL-America offers a variety of unique biomarker assays that may be useful while studying acute kidney injury (AKI) and chronic kidney diseases (CKD).
